QCAD.org Forum

Rookie question I know, but I am a QCAM rookie so no surprise there.

QCAM generates a T1 command in the Gcode that I don't need, as I don't have a tool changer. GRBL complains about invalid code so I have to edit it every time just to delete that line. Minor inconvenience, but I have looked around and can't find the setting to suppress that feature. Where might I find that option?

Version: 3.30.1.0 (3.30.1)

Thanks

Hi, and welcome to the QCAD forum.

This is typically done in the (custom) post processor.
It is not a preference or an option that can be checked/unchecked.

There are some standard included post processors that are intended for GRBL in general.
In the forum there are a few especially customized for certain setups based on GRBL.
Not every setup or supported GRBL dialect is the same.

It is common that a 'T1' or 'Txx' is ignored when already using that tool.
Some CNC drivers need at least an initial setting of a tool number, some may assume 'T1'.

But assumptions are dangerous things in CNC processes.
Exporting a tool number for a toolpath is considered as 'better safe than sorry'.
Tool changer or not, 'T1' >> 'T2' on a manual setup means that you need to swap in the intended tool by hand.

Please indicate and/or attach the post processor that is used.
Also see above forum rules in red.
