Bed Mesh

Bed Mesh

(UPDATE) Disregard, I figured it out.



I have the printer tuned pretty good now. I'm getting the best prints I have ever done with PETG. I love how easy it is to adjust the setting on the Duet. One of the last remaining bits is the bed mesh.


For a CoreXY printer do I put the M557 in the bed.g file or in the config.g file? Does G29 need to be in either of these files? Are there any other M or G codes that need to be included in the bed.g or config.g file.

Not sure of the placement and order of the m & G codes.

On the machine control tab of the web control what does "Run Mesh Grid Compensation" trigger? the bed.g file or??

If anyone has an example of their bed mesh code for a CoreXY printer it would be appreciated.

M557 normally goes in config.g because you normally want to use the same values every time.

If your printer has multiple independently driven motors for the Z axis, then you will normally use bed.g to do bed levelling by adjusting the leadscrews. If not, then you can repurpose bed.g to run G29 mesh levelling if you wish.

"Run mesh compensation" will send G29.
