I am serious about the crying btw and I have no shame in admitting it. I have spent so much time and money on this now, I have been working on this printer for several months now and I am about to throw in the towel and just destroy everything with a sledge hammer out of frustration.
I am attempting to replace the controller of my CR10s with an azteeg X5 GT using BSD2660 drivers for all axis and the extruder.
Had a horrible time trying to find out how to drive a dual Z axis with a slave setup, but thanks to some friendly folks on the reprap forum I was able to get this working.
So now the last bit keeping me from printing is the actual homing and ABL process…
I can home X and Y no problem. Since I use a zprobe and not a z min endstop, I am aware that I need to “home” Z by sending G30 Z1.5 but when I do this after running G32, it will trigger once and go into alarm state. If I send G28 to home X and Y after this, the print head will be dragged across the bed and even worse, pushed into the bed because the grid I probed before sending G30 is apparently ignored completely.
I just don’t understand how to get this right. Please please help…
Here is my config and here is the starting sequence before a print I am using right now:
G28 X0 Y0;Home
G92 E0 ;Reset Extruder
G28 X0 Y0;Home
When I slice an stl using that as start gcode, the head will be smashed into the bed with a lot of force and my BL touch will be warped…
The sensor is mounted besides the nozzle in such a way that at 0,0 it will be beside the bed and the nozzle as well is beside the bed. I tried to compensate for this in the config by setting:
But I can’t figure out if that is the correct way to do it. There is so many similar options to set.
Thank you very much for helping, I will gladly provide more information as needed.
