When I talk about tower positions, I mean virtual tower positions. They may be wrong because of something of this is wrong:
It is interesting that Repetiers radius correction is not mathematically correct. It is easy to do it correctly. At least in Marlin. I doubt Repetier uses same different math for delta conversion. One of the difference is that Repetier uses integers internally so it can be quicker but will have sooner problems with bigger printers. People on google deltabot group also claim Repetier uses acceleration and speed limits for platform while Marlin uses them for carriages.
I used only a temporary mounted probe only. I do not think a permanent probe makes sense. My experience indicates it is needed only once when calibrating. Some people need to recalibrate after taking out the glass and putting it back or after transporting the printer. This was never needed in my case.
- actual real tower position
- carriage dimensions
- platform dimensions
