Great Maintenance List, Angus !! 1) Print a reference item like a Benchi for Before/After reference. 2) Invert and clean generally, esp V-Grooves 3) Check tightness at the Z Servo Coupler screws 4) Inspect all limit switches and wires 5) Loosen rollers & belts and clean / inspect for wear 6) Re-tension belt rollers. 7) Inspect Hot End for Nozzle wear, chafing wires 8) Trim PTFE at Nozzle, clean with scrap filament/ IPA 9) Check all MODs for their unique issues 10) Clean/vacuum out all fan apertures. Install fan debris guards. 11) Lube Lead Screws lightly, clean up any excess, align Screw bearings 12) Inspect Heater Bed wires, connectors. Solder is preferred over crimping 13) Clean under any removable printing (magnetic) for flatness 14) Update Firmware (optional) 15) Level bed, checking many areas for warping. 16) Re-Print the reference item (Benchi) and enjoy!

[@robinmunkittrick4569]

I have to disagree with point 12. Do not solder the wires, use ferrules. The solder will work harden and become brittle over time which will turn into a fire hazard

[@solosailorsv8065]

@@robinmunkittrick4569 soldering with proper anti-wicking and mechanical support does not have those issues. But few hobbiests solder to NASA or USAF standards.

[@QqJcrsStbt]

@@robinmunkittrick4569 I have some wonderful solder loaded heat shrink tubes in a variety of bores. Strip wire ends, a little twist, poke one wire all the out, overlap the other piece, push back to centre position. Apply heat gun (best with digital temp control/readout). The cuffs are flexible with an adhesive inner coating and there is a tube of solder in the centre that flows. Result--slim, neat, humidity tight, strain relieved and a solder join in the stiff centre portion. Bought a pack for a mate who goes ocean sailing. In an emergency you can use one of those blow torch lighters, after all if you are are out at sea with broken electrics, you might have no power and probably no heat gun. DO NOT play that game in the engine bay of a petrol driven craft/car.

"When your machine is apart, it's a great time to print some new upgrades." Unless you have a second machine, it's better to print any necessary parts BEFORE you disassemble the machine.

Right?

[@ForthviewDevelopments]

I picked up an ender 3 last month and it's been great for prototyping, I started with Chuck's Cura profiles and they work a treat, I've had consistently good prints with PLA. My only gripe (so far) would be the couplers on the Bowden tubes which seem to spit the PTFE out at the extruder and I can''t seem to get rid of the elephant foot unless I print on a raft. Wish I'd got into 3d printing years ago, haven't had this much fun in years

[@josephhuelin6997]

Every time I watch one of your videos I learn something else that improves my printing results! Thank you mate! :)

[@RobertoCecchi]

Thank you for this... Maintenance is one of my biggest (3d printing) worries at this time!

[@delscoville]

Just finished maintaining my MP Mini Delta. This is a printer that needs help out of the box! But pleased with it after some work. MP advertises it as an introductory printer that works out of the box, but that's not even close to the truth unless only the very center of the bad is used. Printing bigger causes the nozzle to dig into the bed.

[@Saturn_Enslaved]

Got the 3 Pro after referring to your content, I figured it was best after the information you put forward in your videos. I use an Intermac waterjet and an Intermac CNC machine for my work, these are obviously very different in function but similar in behaviour and principle, I find over holiday periods or reduced work, the machines can succumb to "rust-like" behaviour where errors arise and parts break after periods or inactivity. Servicing our 3D printers periodically is important as the complexity of CNC devices induces a constant state-of-decay, prevention is the best cure ;) Peace.

[@FUTUREDESIGN3000]

A an amazing video on Ender 3 maintenace along with those additional part making tricks using Fusion360!!! I just received my Ender 3 and sponging as much knowledge as I can absorb before I start sitting down to assemble it! The price for mine has gone up a bit to date (March 2021) to CDN $282.99 all in (no taxes and no shipping were charged) from Amazon Prime!!! Still really unbeatable for the quality and large printing area following my research. Thanks much and will be putting a library together of your KZbin tutorials on this unit for reference as I get going. Keep up the good work!!!

[@Doughy_in_the_Middle]

13:00 - I need to say something here for the newbies like me, as I just installed my Ender 3 at the end of May. Rather, I installed my Ender 3 **PRO** at the end of May. YOUR CONTROL BOARD WON'T HAVE THIS ISSUE. This hobby has changed SO much -- As Angus notes in the video -- over the years, and one of the changes was the regular E3 vs the E3P. One of the changes was that the motherboard box is now upside down, and all the venting is from below. You will NOT have the fan opening. Most of the videos out there demo the Ender 3s, and NOT the Ender 3 Pros. Keep that in mind to save yourself the confusion. I noticed that I didn't need the fan mods that were all over Thingiverse, but it wasn't until I went to check on why my USB input looked a little loose (it wasn't; it was the cable itself), and after removing far to many screws, I realized it opened from the bottom.

[@3dmedicvince449]

I would add that it helps to check the fan blades for wear (I had a blade break off) and even clean the edges as dust accumulates and can reduce the air flow. I do this with my big fans in the house as well and can notice a difference in the amount of air blowing out.

[@Cyberdyne_research]

Ender 3 pro. I have more than the cost of the printer in mods. Full Capricorn, full Swiss, brass nozzles, glass bed, 32bit controller, 2nd Z axis, and it’s a beast. I haven’t had an issue in 1000hrs and that’s operating time. Resin printers are better for models and detail, but I’ve printed over 1000 functional mechanical parts about 90% of which have been working for years straight. Also lithium grease is your friend.

[@SteelShadowAnimations]

Perfect timing, as I was just about to do my maintenance on my Ender 3 Pro and CR-X.

[@jacoblf]

even though this is a TWO year old video, and there's been so many upgrades by Ender, this episode is still revelant. eg: simple tightener on the end of the travel bar to manage precise belt tension.

[@nismocapri1]

Hi Angus, I'm running direct drive as well and I mounted the spool on the top so it comes off the roll directly down towards the head, the feed path is a straight line. It works really well. Thanks for all the great information, your vids have been really helpful!

[@yelectric1893]

Perhaps the idler pulley at 6:36 could have a 3d printed other side to make sure the bolt doesn't bend and unnecessarily stress the belt. Thanks for the advice!

[@AlexanderEresov]

Thanks Angus! Please continue with "maintenance" topic on other machines you've got

Pipe cleaners and an old toothbrush come handy when cleaning your printer, to reach all the tiny gaps! Also these sprays with just compressed air are very useful.

Tons of good advice, I have had my Ender 3 pro for about 7 months and have done a few upgrades, but this video helped me with one nagging issue, by belt adjuster has always been bent like yours and I need to straiten it, because it has been rubbing on one edge it is beginning to show some minor wear on the belt. Was thinking of getting a second ender and upgrading to the bigger bed kit and doing it from a new build. Thanks again.

[@FusionSource]

I love my Ender 3 but it does need to be modded. Thanks Angus, great video as always. Some really excellent suggestions, especially the wire fraying part because if the firmware does not get updated, then thermal runaway will not be enabled, which could lead to a fire.

[@paulnortness1354]

Angus, you're the man. I'm kind of turning into the "Get off my lawn" old guy, and I find a lot of videos really bug me. You watch 15 minute videos where the guy is yapping about God knows what and repeating himself to make sure he gets his video a certain length so his affiliate will pay him, then he gives you 3 minutes of useful info. Your videos are awesome, straight to the point, super helpful and you never talk down to newbies. Subscribed and liked.

[@jacoblf]

Paul! you beat me to it! Ditto!

[@spagamoto]

I like to move wire mounts (zipties, etc) around every so often to distribute wear more evenly across the wire. Back in the day I put together my Ultimaker incorrectly which years later led to an intermittent fault in the connection to the thermistor due to wire fraying. It led to my hotend shooting up in temperature which I'm lucky didn't destroy it (the old Ultimakers did not use all-metal hotends) or burn down the house.

[@BLBlackDragon]

Excellent timing. My Ender 3 Pro just started buggering prints yesterday. Probably a clogged nozzle, so a good time for a full maintenance cycle.

[@Ckapolka]

Thank you for a great walkthrough! Your videos helped me a great deal as I started to learn how to use a 3D printer. I'm now printing model skeletons daily for each of my Anatomy students to use at home this Fall, and I was worrying a bit about keeping my Ender running smoothly through a couple months of constant printing. I'll definitely be putting your advice to use!

I recently got a used ender 3 pro. it is doing really well and I am very happy with it. my dad likes the results so much that he is thinking about selling his davinci 1.0 pro to get his own. so may go back through your reviews and recommend something better/more capable for him, or at the least an ender 3 V2 and filament run-out sensor. fyi we have greatly enjoyed the davinci 1.0 pro (we got it for $400 thanks to a warehouse liquidation store) and are glad we got it. I know a lot of people seem to hate the davinci, at least for beginners it is really nice. I like the box design, the way everything moves, and the case. it definitely has room for improvement but I don't see why it gets all the (vocal) disdain it does there are some things I plan to do to my ender 3 pro and I figured while I have it somewhat apart I will go through and do a check-up on it. I am using prusaslicer because it was free and I am liking it a lot. for me it was easier to work than cura slicer (free edition) and even goes to a finer layer height if I so choose. I am putting a Z-axis kit on to give it 500mm vertical, new motherboard so I can put a runout/jam sensor, and a direct drive so I can do flexible filament in the (hopefully) near future the fans on the hot end just started to make some sounds, like debris is in the blade path or a screw has worked itself loose a little and is vibrating. it seems a lot of people like to replace the stock duct work for a new design. they also tend to change the fans from stock. I think I will wait to do so unless I have to but when I do I plan to use noctua fans (I have them for my computer CPU and I love how quiet and efficient they are so I am hoping smaller versions would have just as much quality). for the hardware would it be alright to use a small drop (or use a drop and have it shared with a couple bolts) of blue loctite? in general would there be a written manual with a bunch of steps (with pictures as well) and recommended usage hours between certain checks? I do some car repairs and maintenance so I was curious if the caliper grease I have would be viable? granted it is a grease so it would hold onto any garbage and 'eat' the screw and nut a little faster but I am fine having to replace it after likely years of use. if not i will see about silicone spray, and if I can't find that locally I will try to find some thick and heat resistant grease I am trying some filament from gst3d (USA made with a couple factories around the world). I know you are better at thoroughly testing though. the big reason why I want to try it is if you order 10 KG you get it $9 USD per KG, if you order 20 KG you get it $8 USD per KG (they only do PLA+). where I have been getting my filament from the price is twice as much (about $22 USD per KG). if you would be willing to would you be willing to try some? they have a lot of different colors to choose from Thank you for all your hard work, videos, and sharing of knowledge. it is greatly appreciated

[@francistaylor1822]

Wow, this is the first video I have seen that covers maintenance - I dont know how I missed this topic.

[@Slushee]

I looove doing maintenance to my ender 3 pro. Check the belts, lubricate the Y rod, remove all the debris from the wheels, vacuum the slots, check the cables, remove all the dust from the fans, clean the nozzle, give it a wipe with IPA... It sounds like boring work but it's fun for me!

[@Chrissi33004]

I think its fine that you use grease to lubricate your z axis but you may also consider a (non silicon based) machine oil. I used both and found that the grease was really prone to collect dust or even small plastic parts from my prints which made the Z axis get stuck on them. With oil you can easily spot if that happens and have to clean less, trying to clean out all of the grease was always a bit trickier. Just my two cents on that topic. Also if you're using axis with linear rods or rails, please only use machine oil to lubricate them. Plus silicon grease is usually made for plastic on plastic contact, not for metal on metal. So keep that in mind!

[@RomanoPRODUCTION]

Angus, you are cool and genuine. Thank you for the Pro tips. Daddy CHEP is awesome.

If you take a soldering iron and run it over the solder joints connected to the lcd directly it should repair it. Be sure not to leave the iron over the plastic for more than two or three seconds or it will melt. You will also need to leave the lcd on to see what you are doing.

[@cpace123]

Good video. Minor suggestion. Instead of alcohol for the wheels. Use naphtha. Alcohol can dry out rubber over time. I own 3 laser and which have similar wheels, and you should also use naphtha on those according the manufacture. I also have several 3d printers.

[@danieledm0101]

Instead of grease i suggest to use petroleum jelly, vaseline, which it can lubrificate as well and is not smelly and you can touch with hands

[@wiredforstereo]

The hot PTFE tubing is a poor design. I had serious issues with it, eventually to the point that melted filament was leaking out of multiple places and would not print at all. I installed the Micro Swiss All Metal Hotend. Also replaced the thermistor on the hotend. I have an idler on the bed that will no longer tighten enough to eliminate movement. Time to replace that. I also really want direct drive. And a good upgrade for that would be Dual Z.

Display. You would definitely have a mare of a problem. Visually this looks like CoB, one Com-Seg driver with two Seg extension drivers. Wierdly it looks like it could have a top and a bottom edge silicone/carbon zebra connection arrangement. May be one with a massive amount of tracking out of sight heading south on the topside of the board. That would allow for a hot-bar welded flexi. Lots of connections to the glass then on a fairly fine pitch. Problem uno: the glass is affixed to the board by the metal bezel. The bezel tabs have been twisted and then locked with solder on a wave machine. Could be for security or for EMI/EMC reasons. A lot of patience, flux and braid can get you past that. Problem 2a: If zebra(s), remove. Wipe glass, board and both edges of zebra with IPA. Reassembly could be the hard part. Sandwich it all together again. Apply firm clamping pressure, power up. If good, lock the lugs. Retest. Apply only small blobs of solder to finish (going back in will be easier). Problem 2b: If HB flexi then it can be tricky. Layout unfolded and work your way in from the outer ends applying pressure to the glass and board end connections. One by one. The dead rows (Comms) will likely be consecutive connections. Looking into the glass with decent magnification will probally show you from which end the Coms are being fed, the Segs are either the central block or the other end. If you get a result then a soldering iron will be needed. Three kinds of flexi--exposed, easy--windowed, easy--single sided, tricky. On single sided you have to apply heat through the Kapton backing so try to stay beow 400C. Should ony take 3 to 8 seconds. Warning you could end up worse than when you started. Consider, are find it annoying MM's atitude or plain unuseable?

When would you want to replace the bed springs? I'm guessing it takes quite some time to wear them down. I only ask because when I ordered my upgraded springs I got 3 sets with it like I would need them in the future or something. Haha guess it could be for extra printers if I has them lol
