That's a good thing to have, but I thought, we'd have to home XY at once for a CoreXY?
Another thing is the 'backoff' move. Shouldn't you increase the motorcurrent first, to make sure this move doesn't cause an error?
Why do you abort the macro? Instead increase motorcurrent on every iteration, until it is high enough.

@spoonunit
Nice work. I'm looking forward to trying some of this out.

I run some fairly large production runs on my printers.

Thank you for sharing this.

I've only just discovered this and it works great, however the M564 command at the end needs to be changed to

M564 S1 H1

Otherwise the printer can still be moved outside of the axis.

@droftarts
Feel free
I can send the text and images tomorrow if it helps.

There are no array variables yet, and no vector variables. Here are some ideas:

You could pack several integer variables into a single integer variable, but take care not to exceed 2^31-1. You could create 9 axes in total, then use the offsets of each axis in one or more of the workplace coordinate systems as 9-element arrays

@fcwilt Thanks Frederick!

This is the latest version - most likely won't change until variables are enabled in the firmware.

💡Use the included Macros for filament handling.
To make filament loading, unloading, and changing the most straightforward and simplistic possible evolution, I have made a macro set that is readily accessible from the PanelDue. To take full advantage of the duet filament system you will need to make the system filaments PLA, PETG, ABS, and PC. This will allow you to have custom instructions for each different filament, by adding such to the filament's config.g file. !Note: Based on my current macro version, it is required that each filament's load.g and unload.g remain empty. Placing code into these files will make these macro fail.
"Set Filament Type" asks what type filament you are going to use; PLA, PETg, ABS, or PC. Based on the selection, this macro rewrites the "Heat Nozzle" macro to heat the nozzle for the selected filament type. !Note: This macro only has to be executed once for the given filament type change as it's settings are nonvolatile, regardless of reset or power off. !Note: The script will not let you change the filament type while filament is loaded.
"Filament Handling" is for any filament unloading, loading, and changing regardless of the printer's state, printing or not. This macro will load, unload, and change filament based on two conditions; whether it detects filament is currently loaded or not, and if a print is in progress or not. !Note: The logic function in the macro retrieves the current status of the filament sensor to base the perceived desired action to enact. If your printer's filament is currently empty and you intend to load filament, please do not place it into the extruder until requested to do so by the macro. Else the macro will determine that filament is loaded and that you desire to unload filament, instead of load.
"Heat Nozzle" is created by the "Set Filament Type" macro and can be selected to heat the hotend to the set temperature for the last chosen filament type. You do not need to run this to change filament, the "Filament Handling" macro automatically runs this macro to perform the heating of the hotend to carry out the filament handling, whether it be loading, unloading, or changing.
