How to control the operating status of the equipment?

[Danu]

 

Hello everyone, we are mass-producing small CNC intelligent marking equipment, all using the same specification stepper motors, the same driver, and the same control program.

Strangely, the running feel varies greatly between different machines. Some move smoothly and fluidly, while others run with a stiff rhythm. Even copying the parameters doesn't achieve uniformity.

We have already checked for power ripple, wiring interference, and differences in driver batches, and have even swapped motors for cross-testing, but the problem persists. It's highly likely that the individual electromagnetic dispersion of stepper motors within the same batch is too large, affecting the consistency of CNC motion control.

I would like to ask our peers how they select, match, and standardize the running feel of these types of motors during mass production?

Thank you in advance for all your help and guidance.

this thing can be very helpful and of course you should check driver setup, volts, steps etc.

For my own CNC, I use something like https://www.directindustry.de/prod/muuntosaehkoe-oy-trafox/product-110911-1145655.html
because of my big 7 kW Vacuum pump, which is very electronic noisy on power end.
