CarbideMotion - Pause Retract - 80mm Spindle

Feature Request Carbide Motion
1

Context:
I noticed when I upgraded from the Shapeoko Pro with makita router with Bitrunner v2 to the Shapeoko 5 with Carbide3D 80mm spindle, when I push the ‘Pause’ button during a cut, that the machine no longer retracts (Z-axis) the spindle from the workpiece and stops the spindle.

Instead, it simply pauses in position with the spindle still running. One time when I did this, it created significant rubbing and blackened/burned the stock where it was static.

Feature Request:
Can you make the spindle retract and switch off to 0rpms when ‘Pause’ is pushed in CarbideMotion like it did when i had shapeoko pro+makita+Bitrunnerv2

Thanks!

This occurs in Grbl. The lift-on-pause feature is coded into Grbl as an option which may be enabled at compile time.

The SO5 Pro has dual-Y-axis motor homing, another such option.

Grbl is so memory constrained (2KB):

That it is not possible to have both options enabled at the same time, so a choice was made for the SO5 Pro.

Arduino does make processors with more than 2kb SRAM!

With respect (and this subject has come up numerous times here in the Community, just search Grbl), it wouldn’t matter if there was a Tb of memory, because Grbl can’t utilize it…

If using a more capable board (MEGA2560), then use a more capable grbl (grbl-mega).

The capability does exist, just not for the current hardware.

Acknowledged… It would not be just recompile-with-the-option-enabled… :slightly_smiling_face:
