Robo3d AUTOLEVEL Not Working
-
ok i had to change g30 z0 to z-2now its doing autohoming, guess its time to calibrate the z height
-
as you can see the auto level doesn't seem to be working very well, Do you think i need to run a mesh grid calibration? -

It's a good way to see your bed topography even if you don't use the compensation feature.
Did you end up getting a probe?
-
no i did not get the probe yet. mainly because i havent seen a design for the robo x carriage that houses the bltouch and i dont have time to design it at the moment
-
Does your print bed have levelling screws? If so then I suggest you do true bed levelling adjustment before you run mesh probing. See https://duet3d.dozuki.com/Wiki/Using_the_manual_bed_levelling_assistant.

Not sure what I did but its working again : ) and dialed in

Hi can you point me to some literature about clearing the compensation and running the calibration sequence in as many points as possible?
-
@sleepless Here's the relevant docs on mesh bed compensation
https://duet3d.dozuki.com/Wiki/GCode#Section_G29_Detailed_Z_Probe
https://duet3d.dozuki.com/Wiki/GCode#Section_M557_Set_Z_probe_point_or_define_probing_grid
https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensationThe way to maximize the grid area is to take the size of your bed, and subtract the G31 X and Y offsets to get the area of the bed reachable by the probe. Then you can enter a M557 command into the gcode console with a really small grid spacing. The system will determine that it's too small, and suggest a new grid spacing that should maximise your probe points.

@phaedrux thanks ill try this out

ok so it turns out it was a mechanical issue. One of the endstops was a little loose so it would move when triggered. I tightened eveything up and now its looking much better
