General Mach Discussion / Tangential Problems
« on: May 21, 2013, 11:32:09 AM »
We've been using Mach for a number of years and a lot of our systems use the tangetial mode. One system is a high speed waterjet cutter that uses tangetial mode to cut rubber with a beveled edge.
There is a problem that has crept into the later versions that screws up tangential mode. When I cut a circle all is fine. The propblem is in parts with radiused corners. When the motion tansitions from a straight edge to the 1st radius Mach will take a nosedive in speed (about 90% drop) and the head is rotating a lot more than it should to follow the radius. Anyone else seeeing this? As mentioned, we've used tangetial for years without this problem. BTW, we do use the ESS SmoothSteper board.
