Hello,
I'm new here., but I've been using Mach3 for some time now.
I have a problem.
I had a G-code, a 3D finishing, that worked great on Thursday, it was a 66k line long code.
Then I had another project, that run great yesterday, but that was only a roughing code.
And then today I wanted to run the finishing code, but the Z level kept going upwards. After 10 mins, I was 2 centimeters (almost an inch) over Z0, while Mach thought that I'm at Z-4.
I've had some problems like this, but those were solved, when I set the pulse lenghts to 4-4. That problem was that whole movements were missed. Now it's just steps, that are missing.
They are missing at even half acc, half vel and even at max pulse lenghts, and only on the Z axis.
I've been watching it, and every time is moves downwards and then up again at the same position, the axis of the stepper motor doesn't stop at the same place, but somewhere else with some degrees or steps.
I didn't have these problems with grbl, that was just unstable af.
Here is the program. :

Simítás is finishing
Tetejesikba is just a "pocket"
Could you run the "simítás" file on your router without any workpiece inserted to check it?
I use a 3 axis router with tb6600 drivers and a mach3 breakout board with an lpt connector, and the drivers get 36Volts.
The steppers are nema23 sized "56mm" type ones, as eBay regards to them, with 200 steps/rev. And I use no microstepping.
Could you hep me with my problem?
