Thread: Tool Changing
Possibly a well too many times asked question but my searches only bring up the talk of scripts so please bear with me!
My g-code wanted a tool change so I swapped the tool, went back to the workpiece surface and zeroed the Z axis - restarted Mach3 and the machine went off and started 'cutting' above the surface.
Was my method correct or am I just imagining it should be easier than it is??
Your method is correct.
Provided you did Zero Z axis and the G-code is correct. Only thing I can think of that would cause this is if you have a tool offset applied in the tool table for that tool #. If your not using spindle with tool holders then all tools in the tool table should be zero.
Cheers Jazz, I'm not using a tool table or anything like that - just a plain manual swap by hand and 2 x adjustable spanners. My bits are of different lengths. At least I know the problem isn't with me!
you will need to look through your gcode for the tool length offset call G43 H~ and delete it. Do not delete the M6 call as this is what stops the machine.
If you ever rig up a tool measuring probe and use Mach3 then it is worth looking up Ger21's mach2010 screenset. makes zeroing tool after tool swaps a doddlewww.emvioeng.com
