Re: Auto Bed Leveling doubt

Hi Roxy,

Thanks for you advice. After sending the M502/M500 command I had the 1.65 mm offset showing up in the display but it also messed up with everything else (:P).

If you could be so nice, I have other questions that you may provide answers. They are:

• After issuing M502/M500, none of the motors were moving. Investigating the issue, I found that my feedrate (500 mm/s) was too high. Therefore, I started to play around and found that 12mm/s made them work again (X,Y). Z was alway 5 mm/s. Don´t you think this value is too low? I am using lead screws TR14, 3 mm pitch and all my drivers are set to 1/16.
• As I mentioned before, I am using an endstop as Z-Max and an alligator and old pcb as Z-Min. So, when the bit touches the PCB the firmware knows it is zero. Before the M502/M500 the 3 point auto leveling was working fine but now everytime I send a G29 my Z axis moves until Z-Max endstop is no longer active (goes down and then home again), then X and Y proceed to the next point where Z-Axis again moves down just a little bit until Z-Max is not active. The same process goes on for the third point. Do you have any suggestion on where to look at?
• The last one, once I make the Auto Bed leveling work again, how do I implement the corrections needed? I mean, what commands do I need to send to have the matrix stored and applied to further movements?

Thank you so much for you patience.

Regards,

Marcus
