I built my Plasma machine over a year ago, and it has performed really well in that time.
Today I got a rush job to do on it, and the parts were a lot bigger than I normally cut (500mm square approx.)
I have a problem where the machine is cutting small on the X Axis by about 2mm
E.G
Part should be 505mm and the part was 503mm
The Y axis measurement was spot-on
I cut a couple of parts rotated 90° and it again cut short on the X Axis.
At first I thought it was the Kerf set wrong, but after correcting that the machine still cut short on the X axis.
The machine uses 5mm leadscrews on the X & Y Axis and a 3mm on the Z Axis.
It is set to 320 steps on the X & y and 266.66 steps on the Z Axis
I have not touched the Mach3 settings since I got the machine up and running so I am at a loss why it is cutting short on the X axis.
Is it possible to compensate on Mach3 to get around the problem?
Any ideas?
