A bit of a problem with my BitSetter?

I’m sure I installed it correctly and tested it according to the instructions, but my BitSetter doesn’t seem to be working properly.

Essentially, everything works as I think it should, from connecting to and initialising with the router, which homes, travels to South, prompts to add a bit, then sets the bit height with the BitSetter before returning to South.

I then Jog the bit to the starting point of the workpiece and the cut starts, but it goes a bit wrong when the tool change is due, the workflow ‘Pauses’, lifts the cutter but stays in the X/Y axis.

This happens at Line 882 in both CM 513 and 518.

There is no pop-up on the laptop screen to indicate I have to do anything, with the only options available on the main screen, as shown in the photograph:

I’ve attached the *.c2c and *.nc files. if anyone has the time to look, please.

Thank you

Hi Peter,

It looks like you are not using the right post-processor, go to Edit / Select post-processor and select “Carbide3D Shapeoko”, and re-save the G-code file.

Details if you are interested:

  • you generated the G-code file using one of the other (non-Shapeoko) post-processors, and they happen to deal with tool changes by just inserting a “Txxx” command
  • the Shapeoko post processor on the other hand inserts “M6Txxx” commands everytime a tool change (and therefore BitSetter probing) is required, and Carbide Motion pauses and prompts for a new tool only when it sees that M6Txxx command passing by

Here’s a diff of the two g-code files,

Notice how yours has “M0; T201”, where the one I re-generated from your C2D file with the Shapeoko PP has “M6T201”

In other words, Carbide Motion + BitSetter only works as expected if you select the Shapeoko post-processor.

Thanks, @Julien!

It had to be me, because the same thing happened in each version of CM - and I didn’t think to check the post-processor because I’ve never had to before :thinking:

D’oh!

Always interested! I actually downloaded a file comparison program to replicate your investigative work!

Thanks again :smile:
