Hi Guys,
I have a hypertherm powermax 1650 cnc and am entirely self taught. As such I am having trouble with some things.
My struggle today is getting holes and squares to cut the right size. I am attempting to cut a 50mm square with several 10mm holes inside the square.
Trouble is the holes end up 12mm and the square ends up 48mm. The holes cut counter clockwise and the square cuts clockwise. Kerf value is set to 0mm. I did try setting it to 2mm but for some reason the holes then cut elongated.....maybe a different problem?
I am using 60amp consumables with 3mm plate, 1.5mm cut height and 138volts.
Any help would be appreciated.
Thanks,
Richard.
