Hey guys, I started with an old series 1 machine and have upgraded it to a series 3, including the new steppers and control board. My "official" Tormach controller PC from 2007 finally died so I did my testing yesterday with a newer desktop I keep in the garage. I installed the new V3 Tormach version of Mach 3 and tried to test the steppers. They move! But very weakly. They wont move the table without help.

So is there a current limiting function on the board or in the software im missing? Has anyonet else experienced this issue? I would call Tormach yet again but as soon as they learn that I bought my own VFD and braking resistor they get much more reluctant to offer advice (the VFD wasnt even installed yet) and try to sell me one of theirs.


So is there some reason my steppers are so anemic?

Thanks in advance!
