I'm designing/testing a micro delta (details soon when its working). Running it off ramps due to severe space constraints for the electronics (I know there are much better boards for deltas - I also have a Kossel xl/duetwifi).
I've got it roughly calibrated using the Escher3D least squares method. But I have a tower leaning out about 1 degree. Mechanically fixing it is possible but difficult as the design uses one piece printed top and bottom horizontal sections, so it's not adjustable, the idea is to design a ludicrously simple delta to build, the frame only has 5 component parts, so a little frame imperfection is going to have to be accepted, which for its very small print area 100mm diameter should be doable.
Can Marlin rcbugfix accept a tower lean correction? I presume not as I can't find it documented anywhere. Any other firmwares that I can run on arduino/ramps that can? Is there another strategy that might work to compensate for this?
