Today I tried to set the drivers to 1600 as someone suggested in this other post >>> LINK


While in the motor tuning section I put the values 320 steps 1500 speed and 40 acceleration.

Then I used the auto-calibration tool of Mach3 and it slightly changed value, like 326.5 ....

The axes with this configuration move quite well, maybe it's a little too fast.

What is still not good is the accuracy of the movement, in fact it is wrong about:
- 0.5 cm if I do G0 X20 F400
- 1 cm if I do G0 X40 F400
- 2 cm if I do G0 X80 F400

The positive thing is that when I do G0 X0 F400 from one of the commands above it is not wrong and returns correctly to the point of origin.

What could be the problem? The settings in the driver? Should I redo the mach3 motor-tuning?


For the Nema 23 engine, at the moment I used the same settings (different current values of course) but I have not yet checked if it is wrong during the movements.
