Baby step during a long linear move? Baby step other Axes?

@jml said in Baby step during a long linear move? Baby step other Axes?:
Just another update ... after loading the heightmap with G29 S1, the printer seems to be frozen if I try any X or Y movement. But with some experimentation, it looks like it is just taking infinitely long to execute the move command.
When you do a G1 command WITHOUT an F parameter the G1 command moves at the speed of the last F parameter the firmware processed.
So...
G1 X10 F100
then...
G1 X20both move at F100
So I'm guessing that somewhere you had a G1 command with a very small F value.
Unless you are sure it is not moving at all. The slowest speed is hard to see.

@fcwilt Not sure what was going on when it was moving super slow (or not moving at all). I think it was actually not moving at all after some tests. But it got solved by creating a better heightmap.csv file without the extra commas that excel added for some reason.

And I was able to test it, and the baby stepping is as responsive as I would like - it will now respond quickly after pressing the baby stepping buttons. Hooray!
Thanks for all the input

Glad you got it working.

I'll consider adding a "first layer segmentation" option in a future firmware revision, so that you won't have to create an empty height map - if babystepping is only needed during the first layer.
If you still have a height map file that crash the firmware, please post it so that I can fix that.

@t3p3tony another use case would be on belt printers, from my research and current project the Y-axis is used to adjust height from build surface. I've also opened a topic under firmware wishlist..
