General Mach Discussion / Disable THC Temporary

« on: November 23, 2014, 07:09:28 AM »

Hi! I have THC control on my plasma torch. It works good
but sometimes i would like to disable it in an easy way when i
read reference arc voltage for new materials.
I have a THC ON/OFF button in the gui, but that doesnt seem
to do anything. Everytime i must go without THC i disable all the
THC inputs in "ports and pins" but it feels like there should be an easier
Way to Temporary disable the THC logic?

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.

General Mach Discussion / Holes don't align to center X-axis

« on: February 18, 2014, 04:11:05 AM »

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
