Btw I just experienced the problem that some other users have reported, which is that the expression "${workspace_loc:/${CoreName}/SAM4E8E/cores/arduino/syscalls.o}" in the linker command line got expanded to "". Right-clicking on the project and selecting Refresh resolved it.

Support could be added to PanelDue and DWC to accept gcodes passed to it through messages.

So the message would include the prompt to the user, then some syntax that provides a button (or series of buttons) that the user can press that executes gcode.

Obviously, this only works well if the message is presented at the end of a gcode file, and gives the user options to initiate other gcode macros.

I would also be interested in a way to get the current position (triggered by an input being made high or low, or when an analog sense pin reaches a certain value). Maybe looking at the firmware code for how the endstops/homing works can help.

This was available in Marlin and was very useful for my printer. Hopefully get_position() can be incorporated into RRF.

Ok, thanks.
