New Railcore II Bed Leveling Issue
-
Nothing changed. Prints still don't adhere past middle of the bed. New g29 after 3 g28’s yielded.
-
Do you have the mesh compensation active for the print? Is it trying to adjust for that dip or not?
-
Tried with and without. After just the g32’s no way. After a 16 point g29 it improves a bit but doesnt correct enough for the dip. When I used mesh with the 256 point I did last night, i got a 225mm circle to look great except for one small section at the far end of the drop off.
-
Here is the 4 point g29 they had set up for rail adjustment. It doesn't look bad. Obviously you miss the dip. But does this indicate rails ate reasonable?
-
@dc42 Looking at your post above, you said that it doesnt really matter which 3 point are probed fir g32. I realize you said that because if the bed is flat, any 3 points will determine a plane. I then thought why not use that to disprove flatness. I have tried using sets of different points (avoiding the magnets) and can get very different g29 results after the g32’s. Is that not proof that the bed is not flat?

G31 X2 Y42
can you double check that those values are correct?
-
@Veti those are the values I have been using. Basically I am using the config.g, bed.g and firmware I received from Projectr3d.
-
Finally got a quality machinist’s large square. The bed has those dips in it. Software rules!

Yes, or that the trigger height of the sensor varies with where on where on the bed you probe.
-
It turns out they had some bad beds. Sending a new one.
-
@4lathe Did the new bed fix the problem?
-
@draven much flatter but still a small dip on part of it.
