DLC32 start and stop movements losing position

[tjivanhoff]

Premise: with my old genmitsu everything was ok.

A simple square on lightburn. The machine engraves well the first and the second edges. Starts the third one. Somewhere it suddenly stops for a fraction of second and then restart, and again, and again. At the end, the third edge is shorter. Starts the fourth one. Stops and starts, stops and starts. The fourth edge too is shorter then the third one.

At the moment the microstep configuration is ON-ON-ON, but the problem is the same with every setting.

You can imagine what happens with complex designs...

Where is the problem?

Hi bro I had the same issue before and It was because of lightburn try another version of lightburn

[tjivanhoff]

The problem is over. It was the stepper motor controller voltage setting. When I put the correct voltage the engraver goes well.
