Im currently upgrading my cnc plasma cutter to try to make it better. Ive added a G100 instead of the old breakout board, ive bought a new machine torch and upgraded to sheetcam TNG.
Ive got as far as trying to cut a part and have two problems, im using a touch off switch on the z axis and when the torch comes down and touches the switch and resets the z height to zero for some reason mach is adding or subtracting seemingly random numbers from both the x and y position at the same time, so the machine then thinks it is in the wrong place so cuts to the side of the shape and then cuts the shape. Any ideas? The G code is exactly the sae as i used to use in the old version, it has nothing in it about the x or y axis?
I am also finding my torch on off is unreliable, when i click the button on the screen in mach its perfect but when a program runs it will only work if i ahve recently cycled it on and off manually, if i havent the light comes on in mach but the relay doesnt close?
If it makes any difference i am running under vista and as i mentioned with a g100
Any help would be greatly appreciated
