Setting up Z probe

G32 uses bed.g for bed levelling - the height map is produced by G29

Okay, thanks for that. So where does G32 store the result?

In memory. So it's lost when you restart the firmware.

lol I thought I was the only one doing FSR like this

Tried a G29 and got an error message saying: Error: No valid grid defined for G29 bed probing

Where and how do I define a grid and why can't it use the G30/32 grid?

This page has all the information:

G32 and G29 are currently different, I recommend using G29

stephenc,
I have a Sintratec SLS kit that I use for various things and while I am still sorting things out with it I thought I would make an FSR holder for my much upgraded OpenBeam Kossel Pro.

How do I upload pictures? Tried the picture icon but it asked if I wanted to leave the page and lose any info!!

Thanks T3P3Tony. Reading the right instructions helps a lot!!

I set up the M557 and M558 and ran a G29 and produced a very nice heightmap, thank you. Are these M codes remembered once the printer is switched off or do they need to be put into a config file?

Add them at the end of the Config.g File and they will be remembered!

Thanks Dougal1957 - will do.
