Switched my hotend from a regular V6 block on Hemera to the Revo quick change hotend. This is on a Taz Workhorse with an Archim2 (so quiet!).
Revo hot end nozzle sits about 10 mm lower than the block. G29 works at a Z off set of -1.2.
Here’s the issue…when I try to fine tune the Z for a perfect first layer (at Z -0.5) G29 no longer works. Z needs to be somewhere around -1.2 or it doesn’t seem to work.
I tried putting spacers under the corner discs, but unless the spacers were 0.5mm or less, G29 won’t work. My two options are: raising the entire extruder 1cm on the mount, or going back to the old block hot end.
Anybody have any other ideas?
