This is a great channel and I love your content! I prefer no music if possible. It’s nice to hear the sounds of building, even when sped up.

10/10 servo vs stepper analogy

Моё уважение. Мне все нравится,просто продолжай делать. Ты меня вдохновляешь.

The change in noise will be based on the closed loop board will be using a better stepper driver chip.

Well done. Again. Your progress is inspiring 👍

Amazing vid and router mod! $20 per servo board is a good price

Amazing

I now built my own CNC with the same looped setup as yours, all thanks to you. Keep up the excellent work ❤. Maybe limit switches upgrade next?

Hi! Your video is very interesting as always. But this time I'm not ready to agree with you on everything :) I have the same CNC3110 machine. I tested its accuracy. I researched the phenomenon of "skipping steps" SD. I even tested it under a load of almost 100N and it showed acceptable accuracy. (There is a video on my channel). The problem of "skipping steps" is much less of a backlash problem in a trapezoidal drive. If this backlash is eliminated, the efficiency of this machine can be significantly improved.

The improvement of the backlash is addressed in the previous modification. This was a modification to increase the nut preload on each axis, for example. Increasing the preload increases resistance and increases the likelihood of step-out. The current modification is a modification to prevent step-out from occurring. To further improve backlash, I believe I need to make more mechanical improvements or use backlash compensation with LinuxCNC. I believe this modification would work for machining steel.

@@a-cnc-f I agree with you that Increasing the preload increases resistance and increases the likelihood of step-out. But I went the other way: 1. Removed the spring. 2. Removed long screws. 3. Instead of screw holes, I cut out arched slots in paired nuts. 4. Mounted the slotted nuts against the fixed nuts. As a result, I was able to eliminate the backlash by turning one nut relative to the other. Links are not allowed in your comments. Maybe I'm not explaining clearly, but with an illustration, everything would become clear. :)

Haha you built a mini box for it !

about the Z-axis. there was nothing to stop you from leaving the knob and installing the board on the back side of the feed screw :)

I remove the handle and there is a feed neni there. Eventually, I can't mount the board the same way as the X and Y axes.

Why swap wire you can set direction on MKS45C in the menu -> DIR-> set CW/CCW option

@nerddub

it want that his direction was wrong, is that it wasnt moving at all. he had the coils miswired I believe

@a-cnc-f

It is not a problem of direction. It is true that changing the wiring also changes the direction, but this time, it did not work properly. That was mentioned in the manual.

Hi please could you link the encoders? or at least the model?

Nah this will not work. Stepper motors have higher accuracy than those encoders. Same thing happens with the encoders, they also shift because of gaussian error. Just increase the torque or decrease the speed. High accuracy encoders use optics tech like lasers etc. They measure in nanometer and costs 100k +dolars.

This modification is an improvement to a problem when machining metal on a desktop CNC router. One of the major problems is the step-out of the stepper motor. This is a countermeasure to solve this problem. This machine is for hobby use. If you need real industrial level performance, you need to make all components industrial level, not just the motor.

These servo42c from Aliexpress SUCK. Bought 5 of them, 4 do not work (freeze after booting if EN or COM pin is connected to the controller

Does the motor not run completely after being turned on? If it runs a little but not properly, that could mean that the four wires leading to the motor are wrong. Another way to check is that one motor seems to work, so try replacing the encoder used in that motor with another encoder. If it does not work, the encoder is most likely the cause. It could also be a problem with the encoder settings. But if it is the default, it should be the same. Then use an oscilloscope to check the signals coming to the wires. A tester can also give you some idea.
