Accuracy

Hello,
i finished with my linuxcnc setup and now i have some trouble with the accuracy.
Im using qtDragon and the newest version of linuxcnc (2.9.3 i think).I home my maschine first and after i send it to the G54 g0 x0 y0 z0 and the machine is going there but not reaching exactly the 0 position.
anyone could maybe help me or explain me?
 
 

What type of motion hardware do you have?

Most probably missing G64 P0.1 or whatever the tolerance should be, notice the white line still visible in the preview.
G64 Pnn should be in the gcode file.

I guess a more diagnostic question would be:

Are those the commanded or actual positions?

EC500

well, i just wrote in the MDI field G54 G0 x0 y0 z0 after the gcode what i was simulating.

oh okay, i never heard from that. Im using fusin360 to postprocess my gcode.

Your PID and deadband settings. I suggest bringing the topic into the Remora ethernet thread

edit, oh man this was an old thread
