Hi!
I'am new into plasma cutting. I've managed to get a couple of
decent cuts, but also a whole bunch of bad ones.
At the moment i struggle with a strange problem.
When i try to cut a 200mm shape with two holes in it on both ends
the holes don't align to center on the x-axis. About 2 mm wrong.
I've tried this piece four times with the exact same result. Also tried another
one with the exact same problem.
The shape and hole dimensions do match the cad , but i'd like to have them centered as drawn
The holes are round and the shape it self looks fine.
Iam using:
* Sheetcam
* Mach3
Any ideas what's going on here?
Best regards

Your code and xml seem to be fine from a quick look. Your accel in motor tuning is quite high though, can you reduce that by 50% and see if you still get the issue.

Hi again!
Thank's for your reply.
I've tested some more, turns out that this problem only occurs when using the torch.
With a pen, all moved fine. So it seems like i have some interference problems when torch is firing.
I noticed that the wiring for Z axis limit and Z axis "safety" were unshielded so i removed them yesterday, i'll do some test cut's tonight.

From my readings here. Noise/interference is a real issue for plasma tables. Practice the best wiring techniques.
