OK - now imagine a high speed machine using linear motors capable of 1,600 lbs. continuous force and peaking at about 4,000 lbs. of force pushing a crossbridge that weighs about 650 lbs. This machine will easily run at 2g acceleration rates.
I have to decide soon whether to commit to Mach3 to run this or use my current CNC. What I'm using now will do this, but I'm trying to move to Mach, and this may be the next project for us.
I get that, in theory, Mach can do this. I'm hoping to get feedback from somebody who has actually tried something similar, and to know if they had any problems with the accel/decel, corner rounding, arc tolerences, etc.
