Title: Reduce plasma machine speed at corners.
Post by: dck on August 30, 2017, 03:42:42 PM

Hello,

I have a machine with Mach 3 with a plasma source from Hypertherm and the Sheet cam, I'm trying to implement speed reduction in corners and holes to improve cut quality.

It includes a cutting rules in the Sheet cam to reduce the speed in the corners and in the small holes, the machine does the reduction of the speeds however when it does that reduction of speed the machine of a stop, reason why I realized it it decelerates totally and soon it accelerates Again being stopped a bit in place leaving the piece a little marked by the machine getting a little stopped.

Is there any other way to slow down in Sheet Cam or Mach3, I tried to change the CV settings in Mach 3 but did not change anything.

The problem is in Mach3 itself. Any time Mach3 runs a macro while running gcode, it causes a pause in motion.

This problem was one of the reasons I moved to UCcnc.
