Old Autolevel reset
Hi! I have a suspicion with the calibration of my Delta Rostock Max V1! Unfortunately, despite the very precise calibrations, I am unable to obtain a compliant surface even with G33, I add that the variations of the plane do not know constant in the error towards the outside of the circular plane as on the horizontal plane, but in patches! As if it were in a grid of multiple variations that I seem to remember and bring back to the manual calibrations made with matter Control at the time. Now, I tried to reset with M322 S2 and G33 R0 but despite this nothing changes and therefore I suspect a complete reset is needed, so is there another command to reset a hypothetical old autolevel in the eeprom?
Best is to use the escher delta wizard with 6 parameter to calibrate geometry settings. That normally reduces a lot of the geometrical errors so autolevel is nearly zero and G33 distortion correction also gets minimal.
Shifts in xy should not happen - make sure to not come to much to outside. Here motors start needing higher speeds and acceleration and can more easily loose steps.
Can't say much to the results. It al depends on how close your start parameter were with the real geometry of printer so any geometrically error causes errors in some xy positions be more or less prominent.
But you are right - delta is a model that has the big problem on nonlinearity making everything quite complicated.
