TL;DR I want to know how to tell Marlin the thickness of the feeler gauge I used for manual bilinear bed levelling.
It looks like I've stumbled into a minefield of half documentation, rapid development and personal ineptitude.
I'm a bit of a geek, so I've been following Marlin on github for a while. I have a second hand folgertech 2020. But I don't think that matters. I have a bugfix-1.1.x pull from a day or two ago. That's probably more interesting. I also have a display with a rotary encoder. That might be interesting too.
I'm over here because, unlike the lead developers, I think github issues are for bugs, not support, and I can't find an official Marlin forum/mailing list.
I'm having a nightmare setting my bed height. I think there are a number of factors confusing me:
The Z end stop is not really an end stop. I think it is actually a known position very close to the minimum Z travel.
It is not considered cool to have too many words in the source. Therefore the documentation in configuration.h is slim.
Some of the relevant defines are not available to query or set at runtime.
I suspect software end stops prevents me from positioning below where the Z end stop triggers
I think the trick I'm missing is the z-probe trigger height. But I've been at this for so long, I have brain-fry.
Any tips greatly appreciated.
