General Mach Discussion / Step increment wrong after loading g-code

« on: May 20, 2009, 01:41:04 PM »

Just upgraded to the current release version R3.042.020 and I run into an odd problem. When I first open Mach3 everything works normally. I can jog in increments of 0.001 and the machine moves in increments of 0.001, so far so good. If I then load previously run g-code and try to jog the machine moves 0.025 for every 0.001 requested. I also noticed on loading that the x, y, and z DRO showed different values after loading the file but clicking on any axis zeros all three (I had previously zeroed the axis prior to loading the file).

Any thoughts?

General Mach Discussion / Mach3 toolpath not consistant

« on: October 19, 2007, 10:16:31 AM »

I am having an issue with pockets created in BobCam V21 and routing using Mach3. I get what appears to be arcs that are cut in the wrong direction. I've read several posts regarding the IJ mode. If I toggle between modes I will see the crop circles in one mode so obviously I use the other mode. I've attached a couple of pictures and I'm hoping for a few suggestions on things to try. In letter1.jpg you can see the odd path on the right top of the W. In letter2.jpg and letter4.jpg you see the same letter but the gcode was recreated in BobCam V21. Is there something I need to do in BobCad to make it work?

Thanks for any help and suggestions.
