If a project include different tools like a 2 mm endmill and a 4mm endmill, I the Gcode do not stop or pause for a change off endmill. Would it be possible to ad a field, where we could ad some gcode like M0 M3 M5 M8 M9 in the configure Toolpath sections?
I know. That is why I want to use the M0 (Pause) then i can change the tool manually and probe manually. I have done that in my post process file for Carveco as example. It would be nice to have a field in the toolpath where we could add some g-code that would be added at the end of the toolpath.
you cannot probe during a pause so you must mean you are adding a probe macro after the pause. bit changing during a pause is very dangerous, an accidental keypress during a pause can cause instant motion and possibly also turn the router back on while you are holding the bit/collet/nut/spanner (depends how your machine is wired of course). The right way to do it s to generate separate files for each bit size and do the bit change and probe between files.
Yes David, that is what I do in Carveco se example below (G-CODE FOR Openbuild Black Box) (3.175mm) (------------------------------) (MATERIAL ( X MIN:-95.000 Y MIN:-90.000 Z MIN:30.000) ( X MAX:95.000 Y MAX:90.000 Z MAX:30.000) ( X SIZE:190.000 Y SIZE:180.000 Z SIZE:0.000) ( THICKNESS:30.000) G21 (MM MODE) G90 (ABSOLUTE DISTANCE MODE) G94 (MM/MIN MODE) (=========FIRST TOOL==========) ( TOOL NUMBER:1) ( DESCRIPTION:3.175 mm dia. slot drill) (FEED RATES IN MM PER MINUTE) ( CUTTING FEED RATE:1000) ( PLUNGE FEED RATE :270) ( RAPID FEED RATE :9999) ( SPINDLE SPEED :S18000 r.p.m) (---START TOOL CHANGE AND PROBING---) (Move to manual tool change position) G53 G1z-6 F1000 G53 G0 X-365 Y-729 F2500 (X,Y;Z to be modified for tool change position) M0 (T1 3.175 mm dia. slot drill) (Change tool and press Resume) G53 G1z-6 F1000 G53 G0 X-85 Y-724 (X and Y need to be modified for probe position) G54 G38.2 Z-70 F200 (Probing Z axis) G54 G92 Z51.5 (Z thickness of the probe) G53 G1 Z-5 F800 ( Z maximum up ) G54 (G54 coordinate system) G53 G1z-6 F1000 (Move back for dust shoe mount) G53 G0 X-365 Y-729 G54 M0 (Check Z high then press resume) (---END TOOL CHANGE CONTINUE WORK---) M3 S18000 (SPINDLE ON) M8 (suction on) G0X0.0000Y0.0000 (GOTO PART HOME) G0X-39.9735Y-37.0580Z31.0000 G1Z29.0000F270.0 G3X-38.8510Y-37.5230I1.1225J1.1225F1000.0 G1X38.8510Y-37.5230 G3X40.4385Y-35.9355I-0.0000J1.5875 G1Y35.9355 G3X38.8510Y37.5230I-1.5875J-0.0000
From OpenBuilds CAM use the show/hide toolpath buttons, export a gcode file for each tool you need (full manual control). Between job files you can change tools, probe etc
