General Mach Discussion / Mach 3 vs Shopbot vcarving
« on: July 10, 2010, 11:20:39 AM »
First of all V carving for us is awful.
I am using mach 3 v 3.042.020 with an Ascension 1000 control box. We converted to this from a shop box PRT around 2006.
I have finally got our arc cutting smoother by turning off all the CV settings and adjustments but the v-carving is another story. I am using the Archs inch PP. We had smother v carving cuts when we were using the shopbot controller and software. I have noticed that the files created for the shopbot PP uses a M3 command that allows the router to "lift" smoothly out of the corners. The code generated with the Mach3 inch arcs PP does not use G3 G2 commands it only uses G1 commands for v carving unless there are curves in the fonts, bit the straight portions and the "lifting" out of the corners are real " jerky", not smooth and flowing like I the Shopbot code.  Does any one have any insight?

In our general config settings , motion mode is set to Constant velocity and Distance mode is Absolute and the IJ is set to Inc. CV controls are all unchecked and the Settings Alt 6 page that has the Angular Limit CV is turned off

thanks
