1. Most CNC machines in the shop will use a filter on the air intake of the electronics to keep dirt and chips out. That should be an easy mod. 2. Use an air blower or preferably an air mister with coolant to blow away the chips to get a better finish. 3. Try to have the end mill stick out of the collet as short as possible to keep the tool from flexing... Awesome project!

You are on the right track with the box. I am a control systems engineer. This is my explanation to everyone. You need to make the air in the box slightly higher pressure than the outside. So you need your fan to suck through a fine filter and *PUSH* the clean air into the box or cabinet. You'll find many electrical devices have the fan on the outlet of the ventilation system. Go look at the PSU on most desk top PCSs. My PS4 does this and its something I like to slap a few Sony guys for. The problem is when the fan is at the air outlet its sucking air from inside the box/cabinet which reduces the air pressure inside the box/cabinet. It will then suck in dust from any and every place it can be sucked.

If you aren't happy with the side wall surface finishes, you should create a roughing tool path leaving a few thou of excess stock on the walls, and a secondary "finishing" tool-path to clean them up.. you'll want to reduce the travel speed, full depth of cut minus about a thousandths so you don't mar up the floor finish (only applicable to parts with a floor to finish), and skim the edges to remove the excess stock you left in the first operation, as well as cleaning up, and leaving a uniform wall surface finish. It's common in CNC machining to create multiple operations like this. roughing passes care little about surface finish, it's all about removing material as fast as possible, and a secondary clean-up pass to remove the last bit of stock and leave an acceptable surface finish. Hope this was helpful :)

Really a good build-series. Even though you've used a few Chinese parts, your build is already much better than a chinese CNC. There are a few things I noticed ... 1: Please don't use double sided tape for attaching the heatsinks; double-sided tape (especially foam-tape) insulates against heat and thus keep the heat inside the part you wish to cool down. Instead you can use DOW Corning 340 if you can mount the heatsink using bolts (DOW Corning 340 is not adhesive). Stepper motors do not need to be cooled; most people make the mistake that they think they should not get hot. Normal working temperature for a stepper motor is 60°C (which is: not boiling, but you do not want to touch the motor). If you can't mount the heatsinks using bolts, there are still a few adhesive heatsink compounds available (I know Arctic make some, but they're hard to get as they're epoxy based and are usually sold to companies in larger quantities). Epoxy-based heatsink compounds *can* be mixed with non-adhesive variants, to make it possible to remove the heatsink if necessary; you'll have to experiment with the mixing ratio, though. 2: You could use double-sided tape for the parts you're milling. Stick the aluminum block onto the build-plate with double-sided tape, then keep the holding tabs (at 11:20) and let the CNC remove those gently as the last step - then you hav a part which is ready to use when the CNC is done. 3: A4988 is a good stepper driver to test with; but try upgrading to TMC2209, they should make smoother movements, which will minimize the chatter and thus resulting in a smoother surface on the part. BiQu's TMC2209 v1.2 is currently the best driver (don't get fooled by other manufacturer's v2.0 or v2.2 or 3.x). IMPORTANT: Remember to disconnect all motors, then adjust vREF so it matches your motors and finally connect the motors. If you start by connecting the motors, you'll likely fry the TMC2209's MOSFET (like I did, because I forgot). 4: Arduino is also a good and easy start, however, upgrading to a ARM Cortex-M4 board (recommend STM32F4-based), then you will get floating point calculations and 32-bit calculations at a much higher speed, which in the end means you'll be able to get the ability to calculate curves (bezierpaths) - again, this improves the quality of the workpiece. 5: When I saw your first build, I was thinking that you could probably create your own spindle from good quality ball-bearings and a 10mm shaft; then power that spindle by the motor. Note: Roller-skate bearings are cheap and fairly good quality (I think they're actually 8mm, so you'd probably have to use an 8mm shaft). 6: The 2020 aluminum profiles used for the frame have a circular center, where you can tap a thread; then drill a hole in the connecting piece for a bolt and tighten this to get better rigidity; keep the plastic, so you'll get as much rigidity as possible. About heatsink compound (10 years ago, I worked with this for living) - apply one drop-size heatsink compound per square-inch. Spread it evenly over the surface using a razor blade. It should be a layer thinner than a piece of paper. The job of the heatsink compound is to remove airgaps between the two surfaces and otherwise be "invisible". It should not insulate. Tighten the bolts holding the heatsink as much as possible (without breaking the threads of course). I know you'll probably not implement all my suggestions, but if you (or someone else) can use just one of them, then it's been worth writing it. =)

On the backlash. Their are backlash nuts that are designed to use a spring to push them apart and they are pretty cheap. The benefit is that since your causing more friction the nut will wear out faster and the spring ensures it stays in good contact despite wear.

Just stumbled across this video today. Pretty impressive. Goes to show you, when there's a will, there's a way. Since you already have access to Aluminum and a way to cut it you can replace all the 3D printed gussets with Aluminum for more rigidity. Also, the whole back of the X gantry can be a slab of Aluminum and you can bolt linear rails to. OR, you can build a V2 and forego all TSlot entirely and use Linear Rails bolted to Aluminum slabs. Just ideas; I understand that $$$ doesn't grow on trees.

Having run a cheap desktop CNC mill for many years myself, I would highly recommend using a single flute endmill. You get a much better finish, better clean-out, and lower overall load. Plus, if you are machining plastic rather than aluminum, your cut speed can be greatly increased. I did many many parts in type 2 PVC, UHMW, medium and light density polyethylene, and PTFE. Heck, some of your aluminum parts on this CNC can be re-machined in PVC for a more dimensionally accurate part. Also, you really need to put flexible couplers on the stepper motors. The threaded rod has a run out, even if it's very small. The flexible coupler will keep that run out from transferring into the stepper motor's bearings, thus increasing the stepper's life.

@John Colvin For small desktop mills, I've run the aluminum helical couplers for hundreds of hours. But, you do need to make sure there is no axial misalignment. They can take a degree or two of radial but will quickly fatigue with axial issues. The ones with the rubber spacer have the same problem. Only thing is they will break other things in the drive before they fail. Your best bet for the best coverage is an Oldham coupler with a single flex plate on one end. An Oldham coupler has two dovetail joints at right angles from each other. That way, they can slide to allow for axial misalignment. The flex plate will compensate for any radial misalignment. You could run a multi-section flex plate, but those are very pricey.

@@jameslmorehead : Thanks for that. I saw a simple arrangement I was thinking I might try: (the one I saw was using a cheap Chinese stepper that has the motor shaft and lead-screw all in one.) The stepper is connected to the ball-screw by a non-flexible coupling... the stepper itself is attached to a flexible plate, effectively working as a flexure. This allows some axial movement, but controls rotational and radial movement. There is no bearing at the driven end... axial forces are controlled by a thrust bearing at the non-driven end. Admittedly the machine I saw was a laser, so there was only minimal loads, but anything I tackle will only be small. It worked well, and was a tidy installation. (I must put Gurgle to work checking out the Oldham coupler! 😉 )

@@PiefacePete46 Also keep in mind, on the scale of small to medium desktop CNC equipment, a deep groove ball bearing can carry a surprising amount of axial load. I'd be weary of the lead screw and stepper motor combos. They have to skimp somewhere. Plus, you don't want the axial load going into the stepper motor. They have a spring inside to take up axial play, and these springs don't have much force to them. You can easily get a hard to trace inaccuracy from this type of issue.

If you can get an Ø8 tolerence rod, you can balance the original fan for the motor. You could also just print a new one and balance that since the original isn't super effective. Just put the Ø8 rod through the fan and with some excess rod on both sides, you've essentially got a wheel balancer, just put 2 rods parallel with eachother on a very level surface and put the fan on those. If the fan rolls and stops, it's out of balance. I balanced my original 500W motor fan with a couple of very small bearing balls since it was WAY out of balance. Now when running the spindle at the lowest speed it runs very crooked but at 11k RPM there's absolutely no vibrations.

Instead of tightening the nuts together with nothing to constrain the compression, either shims should be used under one of the nuts, or the mounting holes should be slotted to allow it to be rotated.

I don't think a larger diameter lead screw would add any significant advantage. Perhaps swap from a trapezoidal lead screw to a ball lead screw would be beneficial in reducing friction and back lash, but that was already discussed. As he's not dealing with a large build volume, with vast spans of unsupported lead screw, there shouldn't be any problems. Due to the addition of linear bearing rod, and linear bearings, the only forces on the lead screw would be compression, and tension (pushing and pulling) along it's length. As he's not dealing with significantly strong materials, or exceptionally high torque motors here, those shouldn't be excessive enough in this situation to warrant a thicker lead screw in my opinion.... however.. if he's willing to spend the $$, by all means, go for it XD

A good machine has to be heavy. With a heavier machine you get better finish and precision. As said below try to keep everything as short as possible. Rigidity is the most important in a machine. You have to get rid of those chips while you machine, they can even break the tool. Try using a roughing end mill, to cut out most of the material and then finish it, with a finishing cutter.

If you just make an oversized plastic nut it is naturally zero backlash. Plastic is elastic. Plastic is self lubricating too. Plastic is just another form of oil. You do have to sacrifice some lead screw to make a tap to tap your lead nuts. I found that I had to expand the thread a little or the nuts would be too tight. I just hit a few of the threads with a punch. That blew them out so they cut the threads wide enough. You're still going to get some flex with those unsupported round linear guide bars. Rounds just flex.

I don't advise using alcohol when dealing with CNC machining for several reasons 1) While Alcohol will evaporate, and can dissipate some heat, at a certain point during the machining cycle, heat buildup will far exceed the minute benefits alcohol provides with concern to heat removal, at which time, it actually flashes off too fast, removing even less heat with it. 2) Heat build up increases the speed at which alcohol evaporates, thus increasing the amount of alcohol vapor in the air. This is a fire hazard for very little benefit. This is particularly dangerous when dealing with unknown aluminum alloys, many of which contain zinc or magnesium. 3) Alcohol function quite poorly as a lubricant. The viscosity is far too low, and it's high flash-off speed prevents it from being very effective. 4) While alcohol may be cheaper than WD-40 by weight... It simply doesn't last very long, meaning you will use more and more of it as the part heats up during the machining cycle. This will end up being more expensive compared to using almost any other lubricant such as WD-40, or other such light machine oil based lubricants. WD-40 is not only a perfectly acceptable lubricant for Aluminum machining, it's also one of the most preferred methods by hobbyists and professionals world wide. Unless you're using a VMC or other such high-speed CNC center that uses exotic oil suspension coolants, WD-40 is the go to for soft / gummy materials such as aluminum and copper. that is for a few significant reasons: 1) It acts as a lubricant, which aids in the machining process by reducing friction and heat. 2) It acts as a release agent. If you've ever machined aluminum, you've probably run into a situation where chip evacuation issues, and heat lead to aluminum chips "sticking" to the flutes of the end mill. This is called "Chip-Weld" and is a major factor in reduced tool life, and surface finish problems. 3) Because WD-40 has a high flash-off point, and high viscosity than water or alcohol, it tends to "stick" to parts and tools, maintain a layer of protection throughout the machining cycle, and reducing the amount needed over all, as reapplication is less frequent.

You’ve already got it in great detail…. I’ve read a decent amount of the reactions to your initial upload of this DIY build gem. And i did notice that you take the provided info very seriously and put everything to good use. The result of this build speaks for itself, and it turns out beautiful. You could use 1 or 2mm thick rubber mats for the protection against burs and sliced up loosen material from falling into the frame square/rectangular. By using lubricants to extend your tools lifetime, both wd40 and alcohol based solutions as well just water i warn you that these are all way too thin in viscosity and will have little effect on the purpose of the projective. Be aware that most of the different sort aluminum grades are manipulated in molten state by adding silicate and even harder stone-like materials that will destroy your tools and blunt them way faster than you would think. I mean, silicate is just beach sand. Try little more grease-like substances in small amounts while surface cutting and edge smoothening. Just don’t use grease while cutting inside slots because that will cause the phenomenon “re-chipping” and wear out your tool rapidly plus putting lots of heat in your material to the extent of destroying the tool and failing your end product measurement, looks in surface roughness. I cannot express how grateful I am having you provide me with this back to back build of a CNC-milling machine. Thanks isn’t somehow cutting it 😉

With a roughing pass you'll first mill with like a 1mm offset followed by the actual pass you intend to make near the part but now at least your unevacuated chips have a place to go and thus not getting in the way of the Endmill while its _actually_ engaging the part. I'd describe it as a poor man's adaptive clearing - Still won't allow you to go balls deep with the cutter because after all the roughing pass is as wide as the entire cutter but at least you're regrinding your chips because you don't have a way of evacuating it ( I for one have an MDF Spoilboard so Flood Cooling is an absolute NoGo )

Hey my man, great couple videos I watched. I watched the original build for this one as well. I'm glad that you upgraded your vertical supports. I thought they looked pretty weak on the original. Not weak, just not rigid. I felt the same way about the corner brackets on the base. If I can make a suggestion to you, it would be to get rid of all your 3-d printed parts. That's a great idea for a 3-d printer or light duty router, but I'm quite frankly surprised that it works as well as it does for your heavier duty milling. I would absolutely upgrade the 3-d parts to all aluminium to further enhance the rigidity. You may also want to try linear slide rails instead of the round ones, but that's less of an issue. Keep up the great work my man!!

I will use it for something else. The generic spindle from China has had good reviews but u never know what ur gonna git from that place. Thanks for the Free CAD bro.

looking good, 1 issue though. your heat sink on the spindle is now an insulator keeping in the heat. the double sided tape is insulation and will not let heat transferto the cooling fins. must be metal to metal contact to draw out the heat

@@HyperspacePirate i recommend putting the heatsinks back on, but use a combination of thermal paste and thermal epoxy. Use thermal paste in the center of the heatsink, and thermal epoxy around the edges of the heatsink to seal in the thermal paste + secure the heatsink to the motor. Thermal paste generally has a much higher thermal conductivity than thermal epoxy. You could probably just use thermal paste + normal epoxy if you want to save money. This will do a much better job of keeping the motor cool.

Many thanks for your great video, I am on the process for helping a capenter guy near my home to build one of the wood carving CNC based on your video! However he wanted to build a bigger one with more load (1m-Wx2m-L). I am thinking of a two stepper motors for Y axis but I am worrying that if one of a side motor failed, the Y axis may cause problem. Do you have any idea for fault protection to avoid such case? Please advice with thanks!
@1pcfred
@1pcfred Жыл бұрын
You just use motors and drives that don't fail. When you're running open loop that's the only strategy that works. Go big or go home. What you need to understand is what makes a good stepper motor for CNC. You want a low inductance low voltage high current motor. Learn how to read torque curves. Holding torque is meaningless. You need torque at speed. It is also critical to set the current right on a drive for the motor you're running. More is not better. Stepper motors get hot in use but way too hot is not good. Running rough is not good. Drives with switches to set the current are horsecrap. That stuff ain't right. Performance comes with tuning. Learn how step sequences work. Then you can set the current right at the peak step. Under current performs better than over current does. Bench run your motors and understand how they operate. Figuring this stuff out when it is on the machine is a nightmare. You're probably going to buy cheap Chinese stepper motors. Oh well you'll learn. Spend more and get Japanese motors. Vextas are nice. Finally never ever disconnect a stepper motor from the drive while it is powered up. Or you'll get a lesson in what back EMF is.

@@1pcfred : I'm not a high-level guru; my experience is limited to using it to control a simple DIY plotter / vinyl cutter. I also used it to mess around with a simple mecanum wheeled buggy... it was definitely not the right choice for that, but I had it set up, and it was free! I used it in conjunction with an Arduino Uno and CNC Shield, the same as used in this (and his previous) video. As you say, it doesn't send G-Code. I guess it's more of an interpreter or parser... You load the G-Code file created by your design software (In my case Inkscape with the J Tech Community Laser Tool extension installed), into Universal Gcode Sender. Gcode Sender allows you to view a visualisation preview, jog X, Y, Z axes. You can edit the loaded G-Code file, and manually enter G-Code instructions directly,via a command line. You can Run, Pause, and Abort the output to the plotter (or CNC whatever) which is connected by a USB A to B cable. There is a config area which allows all the setup parameters you might expect, like selecting inches / millimeters, calibrating linear output for each axis etc. It ain't new, it ain't high end, I would say it was someones "Labour of Love", but may not be getting ongoing upgrades, but it is available, there is not much else out there, and IT IS FREE! There are some pretty basic example videos on KZbin, if you are looking to pass time on a rainy day! 😜
