Prusa MK3s Clone 3D printer unboxing and assembly

[@Karafu147]

I've bought this clone a few weeks ago and assembled it now completely and want to share my experience with. First of all i've never owned a Prusa before but generally I'm not new to 3D-Printing. I printed the parts you need for this 3D-Printer out of PETG with my Cr-10 I already had. For the Assembly I think its also not a bad idea to have an adjustable Wrench, because i had the feeling that no wrench I had fit to the nuts i needed to tighten. For the assembly: Generally when istarted assembling the printer I used the FYSETC aasembly video as guide, but later i figured out that the guide from the Prusa Knowledgebase through the assembly is way more detailed and the comments also helped with some problems i had. The Frame wasn't really a problem, with the video also, the only thing I'd recommend, like it's said in the video, that you should take a look at the bearings and test which one works the best before installing them on the Y-Axis. I bought myself 10 bearings from E3D as well, so that i have the choice, if some bearings are bad. For the X-Axis I started to have some bigger Problems. To put the bearings into the printed parts i took a hammer for help and printed myself a cylinder to hammer the bearings into place, because otherwise i didn't have something to get the bearings in the right position. The second problems occured when i tried to put the linear guides into the printed parts. I reprinted the parts for the X-Axis two times because they broke while i assembled them. When i look back at that point I think i would be best to take the X-Axis Motor and Idler development files into you CAD-Programm of choise and create some more clearance. I don't know if that problem just occured because of the bad tolerances of my printer or are a regular issue. If you are not able to modify the clearance or simply just lazy, you can just take a drill 8mm drill and make the hole the right size. Also check again that the bearings you put on the X-Axis and in the printed parts in are decent quality. For the printed parts of the Z-Axis I also recommend to take a drill or just a drill head because of the holes for the linear guides that didn't fit in the first place as well. When started with the Extruder clearance problems occured again with the square Nuts that need to be put in the holes, the magnet that had to be put in the extruder body and the magnet hole in the FS-lever. I fixed those Problems again with adding more clearance, but i had to glue the lever magnet now, because it could fall out. Keep in mind to put the magnets in the right direction that they are repelling each other. Cable management for the Filament Sensor when putting the Extruder body with the backplate together didn't work that well because the cable was to wide, after i teared the three cables for the cabel channel apart it worked. The Heatbreak as it is mentioned already in the video comes with a PTFE fitting what is suboptimal when you using the original Prusa firmware, so I bought an original Prusa Heatbreak that i can also use the MMU2S somewhen, if I want to. When doing the cable management the cable of the Hotend fan and the Fan itself is different from the that comes with the original Prusa printer, so be aware that it should be done decent otherwise the cable can be jammed and in long therm beeing damaged when homing. Same for the PINDA-sensor cable management. Before tighten the PINDA-sensor, try to cut the brim thats on the bottom because if you don't the arm for the PINDA can easily break. For the overall cable management from the extruder i did not exchanged the nylon filament with something else wich worked also if you twist the cable guide good enough. Mounting the heatet bed was very straight forward, but I heard something about the contacts being solderd instead of screwed can be a safety issue, so keep that in mind. When mounting the Board hinges keep in mind that they can easily break, i added clearence to them and even printed them lying, because they broke in the first place. The Heatsinks that came with the board to put on the stepper drivers were too high for the one on the edge and it would have collided with the board housing, so i took pliers and trimmed it down that it fit. After the Assembly: After the Assembly was finished everything worked fine and like it should be. Flashing the Firmware was unfortunately incomplete and led to an error on the LCD that the External SPI flash W25X20CL is not responding. After some testing it seemed like the Firmware was working although I get the LCD error with every startup and I'm unable to change the language. I wrote an mail to ther engineers but haven't got an answer yet. After a few prints I noticed sparks between the holes of the steel sheet. It seemed like the holes of the steel sheet had sharp edges that scratched on the surface of the heated bed everytime i changed the print plate. I "fixed" the open contacts that created sparks with electrical isolating tape but I also contacted the support because of the issue and they told me they will send me a new heated bed. I would highly recommend to coat the steel sheet on both sides with the PEI sheet. Even though I coated now both sides of the steel sheet the holes still seem to leave imprints on the isolating tape on the heated bed. For future I've bought myself another both sides PEI coated spring steel sheet. All in all I'm pleased with the clone and the PRUSA features that came with it, but i wasn't very pleased with the safety of the heated bed even though I mabe didn't do everything right with coating the steel sheet. Thanks for the great Video and the good information @Dombi3D and @Ole Urgast for the useful information in the comments.

Hi did you use something to replace the Nylon filament or did you just ditch it and used nothing als a cable guide? From you text I understood the later but it is not 100% clear to me. Also, did you get YTP bearings with your kit or just no name? I had a different LCD with my kit (black instead of red) which one did you have and cloud you just use the cables without modifications? Or did you have to modify them like Dombi3D did?

[@Karafu147]

@@lusiada6787 Greetings, i didnt use anything to substitute the nylon, but if you twist the cable conduit its tough enough even without the nylon filament. I don't know if the YTP bearings have markings on them, but i think the delivered ones are just no name bearings. The LCD that i got was a black one as well. For me i just plugged the cables in how it "normally" should be and the LCD just worked fine (except th error i described earlier :D). If you are unsure, if the LCD will work after assembly you might want to check it before, just with the mainbord connected with the PCU and the LCD, that you can see if you need change the directions of the cables.

for future projects: instead of cutting off the guiding/security/positioning "pin" and just flip the plastic on the board. yes *just* the plastic can be slid out and reinserted

[@oleurgast730]

Interesting how different the batches are. On my clones the heatbreak was hollow to put the blue tube down to the nozzle (thats the reason I immeditly saw the difference to original Prusa). With a short PTFE already applied inside the heatbreak, the dangerous difference is much harder to detect, no wonder you had not seen it in your first video. The fast changing contents of the box also might be responsible for some reported underextrusion (or bad first layer): Cloned Bondtech gears might be from different manufactures, having a different cut. They all worked fine for me, but need. slightly different eSteps. So for the Clones eStep calibration is mandantory while on the original it is optional. The different heater with 50W is no problem by itself, but require a PID tuning. More problematicly is the potentially different thermistor. Prusa uses "Type 5" of Marlin, while sometimes the clone is delivered with Type 1. This can cause an error about 10°C in meassured temperature. Hard to detect, but I had some Type 5 flying around and used them to be sure. Alternatively you can of course change the firmware or simply print a temptower to get the right "Temperature" to set in the slicer (so you can not use the nice predifined settings in PrusaSlicer). For the bearings: It is more about missing quality controll than generally bad bearings. As I got multiple Clones (3 Fysetc Clones of the Prusa Mini, 2 Fysetc Clones of the mk3s) I changed two of the clones to high quality bearings - and for the other clones I tested all bearings by hand, sorting out the bad ones. So in summery: The Fysetc Clones (of the mk3s and of the Mini) are quite nice. But you need additional parts and steps in asembly. Also you need some calibration that is not needed with an Original Prusa - but of you do so, you get same quality as with the original for less than halve the price. I recommend following parts: - e3d Heatbreak PE (you can get the special PrusaEdition from 3djake), so you solve the heatbreak issue and also might add an MMU2 later - a Type 5 thermistor - some extra bearings to replace the worst bearings (or a complete set of higher quality bearings) Of course, as you print the plastic parts yourself, in some aspects the Clone can even be better than the Original Prusa. For example the filament runout sensor often is not reliable in the original, as it tend to stuck. It is caused by Prusa printing the parts with 0.3mm layerhight quite fast. So if you use 0.2mm layerhight or less to print the parts of the printhead and print slower, this problem is solved. Also you can even use the old filament sensor (wich also detects if filament moves!) as its missing reliability was caused by the high reflecting PET-G. So if you print the parts yourself, simply use non-reflective black ABS for the printhead (or, more easy to use, ExtrudR Greentech pro black). Of course the most important change: Modify the display case before printing and replace "original" by "cloned" ;-)

[@Dombi3D]

Thanks for your comment again! I will use a HSS nozzle on my new builds which requires around 10°C higher printing temperature so I hope that the temperature difference caused by the different type of thermistor will get balanced with the predefined printer profiles.

[@oleurgast730]

@@Dombi3D Interesting solution. If I remember correctly, the special heatbreak Prusa uses also require a little more temperature than normal (I think 3d printing nerd had that problem with a certain filament in one of his videos). So maybe the professional solution would be to print a temptower with same filament both on the Original and the Clone and compare results to find the practical difference in hotend temperature needed. If I remember correctly, you can set a temperature offset in advanced.conf. Or maybe use a second nozzle of same type (both on original and clone), drill it wider to insert a reference temperature sensor, and make your own fitting resistance/temperature table for the clone with all it changes... It is esp. interesting if using a mix of original and cloned printers - so the gcode is the same on all mk3s. Prusa firmware is a bit special, a bit different from main Marlin fork. But theese parts are quite stock. So change and compile is not a big deal. A bit more complicated is the Prusa Mini, as you have to compile the firmware for every change (eSteps, PID...) as it does no M500. Of course you can edit start-gcode. But with a mix of Originals and Clones with different modifications this means different printer settings for every printer. I so much prefer every printer being calibrated for its own, so only one printer profile for all printers of a type (O.K. I always have one second profile with virtual extruders for manual multicolor, but not with different startcodes)

[@natebigg802]

can i just use capricorn tubing

[@oleurgast730]

@@natebigg802 Capricorn uses PTFE with some additives and more precise manufacturing. It solves some issues low quality tubes have, like deforming early, but If you get to the temperature PTFE degrades, all this do not help. If I remember, deforming starts mostly on 250, degrading on 275. On Capricorn deforming is reduced by additives. But degrading still happens If your printer preheats to Polycarbonate. Anyway - a full metal heatbreak is in the same price-range as Capricorn - and you get no advantage of the higher precisision on the very short tube inside a direct extruder. Also of course it does not have the inner structure to form the tip if you want to add an MMU2 later.

Square nuts for the extrusions I can live with, but they lost me with the slot-head screws, c'mon. Good idea to put some thermal compound between the heat break and sink.

@@Dombi3D I see, so you used those in place of the wrong-length screws they provided, thanks for clarifying, not that wrong length is much better on the manufacturer's part. My FLSun i3 clone also came with square nuts (which I eventually replaced most with T-nuts just for ease of reassembly during maintenance), but had plenty of allen-heads of various sizes left over to swap around. E3d all metal heatbreak was also a big improvement over the knockoffs i tried first.

[@lusiada6787]

Hi Thank you for this video. After seeing the video and already owning a Prusa mini clone form Fysetc I decided to buy the MK3S and the MMU2S from Fytsec. The MK3S Prusa clone is almost built (only the wiring and cable management has to be done.) and the process was pretty straight forward. I used the videos and the guide from Prusa, I think using both is a good strategy as the one is a video (which is not very good by the way) and the other only foto's and text, the video can be more explanatory in some circumstances. The only thing I am wondering about is the nylon filament guide, I am wondering why Fytsec does not include this and if is 100% necessary. In the assembly video that do not use it also. One other thing i would like to mention is that Fytsec seems to have made some improvements, I got different square nuts which seem to fit perfectly and I got bearings from YTP which look very good also, I had ordered IKO bearings form Triangle labs and used those but the ones that cam with my kit (YTP) look as good as the IKOS and much much better then the ones that came with the Prusa mini clone. So I used the IKO's and will use the YTP ones for my Prusa mini. Also, I cleaned the bearings with isopropyl alcohol and put fresh superlube grease on them. One other tip that helps with bearing problems and loud sounds etc. is to lossen all rods just a bit after assembly of the gantry's move th agentry's back and forth and tighten it again. I also exchanged the heatbreak for a Triaglelabs Titanium one and brass heatblock also from Triangle labs. Not sure if the brass heat block will cause any issues with temperatures and the used cartridges. Time will tell. Regarding the electronics, I seem to have a different LCD, mine looks better than the ones in the video and the ones shown by Dombi3D, mine has a black PCB with very clear text on it and good soldering, but not tested yet, not sure also if I need to do the cable modification. Regarding the filament detection sensor, on the Prusa guide they say you shroud use the red sensor, but in the kit there is a black one, not sure if this will cause any issues with the Prusa firmware. @Dombi3D, You have stated in your video about testing with IGUS bushings did you test that already and if so how are the results? I am planning to exchange the LM10UU Z axis bearings on my Prusa mini clone and the Z axis bearings on my MK3S clone with these IGUS polymer bushings but want to know how the experiences are.

[@Dombi3D]

The tests are ongoing. I am testing 5 different bearings and I want to make the test more scientific with accelerometers etc. which takes more time as I expected. However I already Printed with the IGUS bearings and so far looks good. You just need to take car to not clamp them too strong because then they will have too much resistance. For Z axis I use IGUS for 6 printers. I am working on different projects but I really hope that I can manage that Bearing comparison video also in the future.

[@lusiada6787]

Hi Everybody, Since this place seems to be the best place to exchange information on the Fysetc MK3S I am going to post my build results as it is running and printing now. First the trouble and how to avoid it: Filament sensor. Do not over tighten it! Make sure the leaver inside as some clearance and moves freely. First sign of filament sensor not working well is the auto filament loading not working and in settings IR always stating 1 even without loaded filament. Cracking of the x Axis (or are they actually Z axis) parts (x-end-idler and x-end-motor) one cracked slightly pushing in the rods (fixed with a dab of contact glue) and the other cracked while tensioning the belt (still in place and working but will have to be replaced, will leave that for when I will install the MMU2S also from Fytsec). PINDA, make sure to adjust the hight correctly otherwise a lot of calibrations and checks will fail, I use a creditcard or back card for hight with the nozzle a 0 then lossen the Pida and make sure the bank card just fit snugly under the PINDA and then fasten it. Z-axis misalignment (not fixed yet) some how I notice that a couple of times my right side is one or 2 mm lower then the left. After turning off the printer and manually turn the z lead screw and measure it with a calliper all is fine again, but it comes back once in a while, anybody experienced this behaviour and if so did you got it fixed? If you got this fixed please share how? Setup process (not fixed yet) the complete process goes well but the Z axis calibration check at the end fails at the Z axis check. to sure why but the printer is working fine. The electronics case and cable management inside. This is a complete nightmare! Just did what the video from Fysetc shows bundled it but a tierap around the cable bundle shoved everything inside, closed the door fastened the screw. Obviously I am not happy with this solution and I cant imagine this will be good for the cooling of the Eynsie board. So one of the first things I will replace is this. For the rest it was pretty straight forward and I must say that I am again pleased with Fysetc that is fast becoming one of my favourites on Aliexpress, also because the support until now has been amazing! Anyway, Hope my pointers help other to prevent the issue I ran into! @Dombi3D I almost cant wait for you bearings review (it is a pity you did not include the IKO's but I can say from my experience they are amazing!) and maybe even more anticipating the MMU2S review as I want to wait for your experience before I start with mine. Somehow I had etc feeling that one will be hard work to get it working correctly and stable.

In general it should work, but PLA or even PETG tend to have better Layer Adhesion than ABS. Allthogh ABS has more Impact strength, but dont know if you need that in theese parts. If you just dont want the parts to break you could just adjust the tolerances of the CAD files of the X-Axis parts.

The cloned gears are not from Fysetc; Fysetc buy them from other chineese manufactures. In different batches you might get different cuts. There is a cut that was intended for 2.85mm but also work with 1.75mm. And a cut for 1.75mm only, like the original Bondtech. Due to the different cut you have a different effective diameter. So in an mk3s you need 830 esteps/mm for the 1.75 only cut, but about 870 eSteps/mm for the other cut. If you have underextrusion with stock settings, this is the first point to check...

@@oleurgast730 Hi Bought and installed the IKO ones, must say that they are a big improvement, well worth the money! The YTP ones that came with the printer don't look bad at all, will install these on the Prusa mini clone as the ones that came with the mini are terrible. I cleaned all bearing with isopropyl alcohol and greased them with Loctite Superlube.

[@cobusgrobler662]

Nice video, thanks. Are you perhaps going to do a review on the clone MMU2S kit as well?

[@Dombi3D]

I thought about it because I am printing already with more colors but I swap the filaments by hand. As I saw many people are not satisfied with the original MMU2s either, I did not purchased it yet, but could it be that the functionality is the matter of the assembly quality. Now I really think about to order one :)

i brought my hotend from e3d and it was prusas kits i ordered direct from e3d and theres had the teflon tube

[@arturwolf]

What do i do regarding the 3D printed parts?, i already bought it but it's my first 3D printer, is there any way to temporary assembly it to print those parts? or any work around? (i bought the bear upgraded one) should i buy a set of 3D printed parts for the Mk3s Bear?

[@Dombi3D]

If you do not have any other 3D printer to print the parts yourself you have to purchase it. After it you can make as much 3D printer as you want :)

Why go prusa clone vs ender3? I have a prusa and debating on a second ended 3 since I can get 2 for the price of 1 prusa clone, or 4 for the price of an origional prusa

[@jonatanrullman]

If we ignore the inherent differences in construction and just focus on quality and what you get for you money. I'd say that the genuine Prusa is high quality and well thought out with pretty much everything included. It will cost you just shy of $800. The clones are, as we can see, pretty good too but could use with a couple of replacement parts. Base price is about $350 and a couple of essential upgrades is another $100 so slightly more than half the price. The Ender 3 Pro is frankly a bit of a mess. It's basically a nice printer but to just get it workable you will want a glass sheet bed, replace the entire hotend assembly with the hero me gen 5, replace the extruder with something decent, new part cooling fan and belt tensioners. So you're going to spend something like $180 and then another $100 for upgrades, a bunch of prints and a couple of evenings installing all of it. And you are still just at workable. Add the silent drivers (which you may get for free if you're lucky), bed probe, spring steel sheet and everything else to get an ender to the same functional level as the clone and we're talking bare minimum another $100. The ender is nice to play with but it is not in the same league. You could get the Ender 3 V2 and get a much better baseline but then you start at $300 and will still need $100 to get all the trimmings the prusa clone has.

Built a PrusaClone: PETG at 230 degrees First layer cal looks perfect. go to print something and after a few minutes the filament starts to fade. Looks like the stepper stopped grabbing the filament. But why? it was so perfect. I suspect that the stepper is overheating and the heat is warping the filament overtime until it gets to soft to grab? I tried loosening the gear screw and had no luck. Any ideas?

[@Dombi3D]

That could caused by several things. Clogged nozzle, Heat creep, bondtech gears are not aligned, Teflon tube misalignment. -If you can manually push the filament trough the nozzle than clogged nozzle is not the issue. -The clone has a strong nozzle fan so I would not think that it is heat creep issue. (PETG also not prone to that). -Check if you aligned the gears with the hole. -Check if your Teflon tube in its place. If Teflon pieces goes inside the tube can clog your nozzle. Because the Clone comes with a Teflon tube inserted in the heat-brake on the heated side also, can also cause issues by retractions.

[@UnrealApe]

@@Dombi3D I had upgraded my heatbreak as per your recommendation. I also used an upgraded nozzle. I have aligned and realigned the gears a few times with no luck, but i can try again, i was thinking the gears are cheaply made and i should upgrade them to bondtech gears... Teflon tube seems fine. I ended up using one of the original prusa ones i had laying around, and it is the correct length. What else should I consider?

[@Dombi3D]

@@UnrealApe in this case turn up the nozzle with around 10°C could be that the temp is not high enough to melt the material. First layer printed slower and that is why it could print fine but when it speeds up not anymore.

[@UnrealApe]

@@Dombi3D ah yes, I forgot to try to slow the print down. Thanks I will test it some more🙏

i just received printer. I broken extruder idler plastic part and now i have to wait to print another. May i ask you how u connect hotend 2 wires that have no connector at end wires? Should not be there a connector for motherboard? The wire for temperature sensor have a plastic connector at the end, but thermistor have 2 wires without any plug.

[@Dombi3D]

There is a screw terminal type connector in the package. You can build the 3d printer, make the wire management and at the end cut the cable length, free up the ends from the insulator layer and screw inside the connector, after that you can plug it into the Einsy board. Polarity does not matter.

@@Dombi3D man this hotend is crap. I put petg and it clogged inside radiator and overfilled on entire extrusion assembly. It extruded like 2 cm after i finished calibration and wanted to adjust live z . now i have to buy another hotend, i think i buy from prusa straight. This printer is kinda crap. Also some holes from frame for einsy case mount are not properly threaded. A lot of issues. But hotend is a crap. Now i wait 2 weeks more to get hotend from prusa.

[@Dombi3D]

@@Flavius-Tech I am over 2kg of PETG with the stock clone hotend parts without issues. Are you sure that you assembled the hotend properly? No filament should escape anywhere just through the very end of the nozzle.

[@oleurgast730]

The original Prusa mk3 kit was my first 3d printer about 2 1/2 years ago (exept from a toy, the fischertechnik 3d printer). This was before chineese mostly preassembled printers where sold. So I also started without experience. But due to the very good assembly guide, there was no problem at all. The only advantage of being experienced is becomming faster on assembly. My assembly time got down from 9h to 4.5h, as I do not need to look into the guide anymore and also have some tools like electrical screedriver with fitting bits. So do not get frighten by the many parts - assembly takes time, but it is not complicated. And you get the best printer in its price-range. For the Fysetc Clone only 3 things to be changed: Buy a full metal heatbreak, the original Prusa thermistor and the bag with Harribo bears seperatly (the Haribo can be substituted by any alternative sweets without effect in print quality ;-) As preassembled chineese printers often have loose screws, I have found many of them even more complicated to tune in - I had errors and had to research the cause. This never happened on my mk3... So even for beginners, I recommend such a kit. The time you spend for assembly is well invested. You spare more than that afterwards. The Prusa mk3(s) with PrusaSlicer and predifined profiles is much more easy in usage - so spend a weekend to build it will save you lot of time while using it.
