Mesh bed leveling gone wild!
-
Just deleted the bed.g and config-override.g. Now it starts the mesh bed leveling at X-2 but still does not go past X98. Looked at the config.json and it does not match. Could this be the issue? If so do I edit it to match? It also thinks the firmware is 1.17 and I have 1.18.1

Just changed to M557 X10:200 Y10:200 S20. Now it goes to X165 and the Web interface mesh display on show 1 row of coordinates at X190 here is my heightmap.csv . Does anyone have any ideas? I getting ready to pull out the SLEDGEOMATIC!

Looks like the firmware thinks that X10 is not reachable by the probe, hence the initial column of zeros. In the config.g file you posted earlier, the X movement limit (M208 S1 X) is -22 and the probe offset (G31 X) is +32, which puts X10 right on the boundary between reachable and not reachable. Try X11:200 in your M558 command instead of X10:200.

That seems to work for the left side of the bed. Still does not seem right yet. This is what I just ran M557 X11:200 Y10:200 S40 and this is what I see only points on right hand row.

What about the config.json mismatch?

I just spotted this in your earlier post:
It also thinks the firmware is 1.17 and I have 1.18.1
If it thinks the firmware is 1.17, chances are that it is. Send command M115 to check. If the upgrade to 1.18.1 failed, you may need to upload the latest iap4e.bin before you upload firmware 1.18.1.

Also did you see the heightmap pic? Just one row of data show up. Does not appear to be work as it carved out my PEI !
-
I guess that may be an artifact of how DWC responds to the column of zeros. I'll ask chrishamm to check it out.
-
Why am I getting zeros if it is probing X11? What about the rest of the data as well?
-
Your config.json file doesn't agreed with the config.g file you posted earlier. Please post your current config.g file again.
The version number in config.json suggests to me that you created it before you upgraded the firmware.
-
Like I said they don't jive. I did the full firmware again and same thing. Ran m997 no change to config.json

So i was having the same issue of 0's in the first column, and only displaying part of the mesh in the mesh visualizer, I had unwittingly made my X start point value for the probe grid below my X offset and the first column was 0'd out for the 16 point grid.
-
I was 2mm inside the the offset and just for giggles changed it 27mm and shazaam! It started working! I guess you can't be close to the edge…..
-
Now to try a test print.
