z=0 inconsistent
-
Hi,
I have a ender 3 pro with a bl-touch on the duet maestro. as stated in the subject my z=0 does not seem to be setting or is some how changing. i removed the springs form the bed and have it hard mounted. I leveled the bed using mesh bed compinsation and adjusting the hard set level. I am honestly not sure if it is pulling the saved height map or not but every time i set my z 0 and reset z offset if i home and check my z 0 it is not where i set it at. any ideas on what could be causing this?thank you

Please post your config and homing files. And your slicer start gcode. Describe the order of operations you're using.
I have the springs still installed on my ender3 pro with a BLTouch and haven't noticed any issues from them being too springy. Though I did have to remove the Z endstop as the bed was cupped and the nozzle wasn't able to lower far enough in the center to touch the bed unless I raised the entire bed with the leveling screws which made them a little loose.

I think i might have worked it out at this time. i paper tuned the z=0 at all 4 level screws and checked my center z=0 to find that my bed has developed a big dip in the center. I have placed the G29 s1 code in my slicers starting code and it seems to be making the necessary adjustments.
thank you for the quick reply

Yes I think that's quite common for the creality aluminum beds.
