Hi, is it possible to generate a gcode from fusion containing information about rotational speed and spindle cooling? lead1010, black box
Yes, it (the OB postprocessor for GRBL) always does this.... M3 S12000 where 12000 is the rpm you set in Fusion for this tool. If you have set Flood coolant for the tool, then and M8 and M9 pair will also be output. For this to work automatically you have to correctly wire your spindle to the Blackbox (if that is possible for your spindle). also the Blackbox must be told the RPM range in parameters $30 and $31 which you can do using the OBControl GRBL settings panel. If you have a Dewalt/Makita/Router11 then the spindle speed knob settings is in a comment in the Gcode, make sure you select the correct spindle when posting.
