Change Z-babystepping to Y-babystepping for Belt printers.
-
Hello,
Would it be possible or is there a way to change Z-babystepping to Y-babystepping? I'm building a belt printer and the distance from the print surface is controlled by the Y-axis on a belt printer.Thanks

The M290 command currently only supports Z babystepping, but it would be possible to extend it to support other axes as well.

I could see this feature being useful for fine-tuning the alignment of tools on an IDEX printer.
On that note: does babystepping function on a per-tool basis, or is it an augmentation of a single "machine coordinate system?"

It applies to all tools. I guess we could add a command to shift the babystepping offsets into the offsets of the current tool and clear the babystepping offsets, but I'm not sure whether that would be useful more generally.

Personally I would prefer to alter the X and or Y with a G10 offset in my config file or manually. Once I change hotends I always get my offsets dialed in before doing any real prints. Then once it is set I haven't had any alignment issues.
Just my opinion on this, nothing more.

Hmm, maybe a good solution would be to simply allow a modifier in the babystepping GCODE to tell the printer to apply it to only one specific tool?

I agree. I could only picture using babystepping to discover the best offset to apply manually/permanently.

@dc42 That would make dialing in a belt printer much easier... I would be more than happy to test the feature should you implement the ability to baby step the y-axis.
