CNC USB CONTROLLER MACH3 UPDATE

It is a bit annoying to do this manually but at least it works! Load the PFG gcode into MACH3 and then you will be asked to manually confirm if the g31 commands should start or if they have finished. Then its simply a case of loading a gcode file and GENERATE PFG The Z initialisation block was modified to use a custom block and M2002 was replaced with M2003.

To try and fix the first problem, I used a macro to insert a delay before and after the g31 gcode command.ДЄutoleveller was set to use a custom controller and the custom controller options configured with the Pre-probe command set to M2001 and the Post probe command set to M2002.

The triple file is used by autoleveller to generate the height map so this is a significant problem.

The g31 command should write the triple x,y,z values to a file opened with the M40 macro, unfortunately it doesnвЂ™t.

The g31 command doesnвЂ™t update the 2002 variable.The g31 command will happily run from the command line, but it will fail to complete if it is run from a gcode file containing other commands.This was the case with the usb controller card supplied with the Sainsmart Genmitsu 3018-MX3 mini cnc. Unfortunately the G31 command implemented on Chinese MACH3 usb controllers is often found not to be fully functional. This allows very fine traces to be milled from the thin copper layer of pcbs.ДЄutoleveller uses the G31 gcode command to probe the height at several locationa. which is then used to modify gcode to take account of height variations. Autoleveller is a program used to aid in the process of milling printed circuit boards by probing the surface height of the pcb and using the probe data to create a height map.
