Hi there,
I just got my Duet electronics + expansion, and I have some plans as to how I want bed leveling to work.
However, I need to adjust the firmware to fit these needs, I've done some adjustments inside marlin firmware, but never in reprap firmware, so i'm not sure where to look.
Anyhow, my plan is as follows:
I want my bed to have 3 axes (3 z motors) 2 in the front, 1 in the back.
But i want these to be able to move independetly (my plan was to use the expansion board for these axes).
The idea is, that the hotend moves around the bed, probes some points, and saves the differences for each axes.
Then i can compensate, by that amount, for each axis.
So the changes i have to make are:
- Adding 3 seperate Z axes on the expansion board
- have a function saving the z positions when probing
- calculate those differences, and make it an offset for the z axes
- have a gcode routine for probing the bed ( this one is easy)
No ofcourse i don't need to compensate all axes, as the back axes will be the "Main" one, so the front 2 should compensate based on the difference with the back axis.
I hope i made my intentions clear, and can get some help as how to go about this.
I'm definitly not an expert programmer, as I only know the basic arduino programming functions (#define #ifdef means nothing to me) However, i'm always eager to learn more, and i learn quite fast.
So any steps in the right direction are greatly appreciated!
