Hello all. I am new to the OpenBuilds software and grbl Post Processors. I recently built a JDs Garage Plasma cutter running the Arduino Uno R3 controlled by the Openbuilds with Grbl. I design in Vectric Cut 2D and Aspire. I emailed Vectric and they helped me get a working Post for my machine. It works well but I want the Z axis to raise to a safe height in between cuts and I do not have a clue how to. Vectric basically just copied a post I had from Fusion 360 and they say they dont know much about how to get it to do other things. So could anyone help me modify my post so as to raise the Z to a safe height in between cuts as to not hit tip up peices? Here is My pp. I do understand the G0=(pierce height), G4=(pierce delay seconds), G1=(cut height), but thats all I can figure out. begin HEADER "(Made in Vectric Plasma Post Processor)" "G90 G94 G17" "G20" "G54" "G0[XH][YH][FP]" +--------------------------------------------------- + Commands output for rapid moves +--------------------------------------------------- begin RAPID_MOVE "G0[X][Y]" +--------------------------------------------------- + Commands output for the plunge move +--------------------------------------------------- begin PLUNGE_MOVE "G38.2 Z-3.937 F6" "G10 L20 Z-0.122" "G0 Z0.25" "M3 " "G4 P1.8" "G1 Z0.2 [FP]" "G1 [X] [Y] [FC]" +--------------------------------------------------- + Commands output for the retract move +--------------------------------------------------- begin RETRACT_MOVE "M5" "G0 [X] [Y]" +--------------------------------------------------- + Commands output for the first feed rate move +--------------------------------------------------- begin FIRST_FEED_MOVE "G1[X][Y][FC]" +--------------------------------------------------- + Commands output for feed rate moves +--------------------------------------------------- begin FEED_MOVE "[X][Y]" +--------------------------------------------------- + Commands output for the first clockwise arc move +--------------------------------------------------- begin FIRST_CW_ARC_MOVE "G2[X][Y][J][FC]" +--------------------------------------------------- + Commands output for clockwise arc move +--------------------------------------------------- begin CW_ARC_MOVE "G2[X][Y][J]" +--------------------------------------------------- + Commands output for the first counterclockwise arc move +--------------------------------------------------- begin FIRST_CCW_ARC_MOVE "G3[X][Y][J][FC]" +--------------------------------------------------- + Commands output for counterclockwise arc move +--------------------------------------------------- begin CCW_ARC_MOVE "G3[X][Y][J]" +--------------------------------------------------- + Commands output at the end of the file +--------------------------------------------------- begin FOOTER "G0 Z0.6" "M5" "G0[XH][YH]" "M30"
I know this post is old, but did you ever get it working? Or have you found a good post processor for grbl based plasma cutter? I have a grbl based plasma that I'd like to use with vectric. Current work flow is design on main computer in office with Vcarve pro 12, export dxf to openbuilds web based cam for tool paths, then export g-code to openbuilds control on the tablet on the plasma cutter. I would really like to export the g-code directly from vcarve, because having to change anything and re-cut the file means editing, export dxf again, redoing the tool paths in cam, and then exporting a new g-code. I haven't been able to find a grbl post processor for vectric that let's me add pierce height, delay, cut height, touch off, etc. I like the openbuilds cam, but I would prefer to eliminate a step. And the vectric tool paths are better at calculating lead in, overcut, and leadout. And openbuilds cam can't do open vectors for thin lines on anything other than straight lines
