Resetting Z Height on M2E After Nozzle Change?
Posted: Wed Jul 19, 2017 2:07 pm
I've been searching for simple instructions on how to do this, but all I've found is info on earlier machines. I can run through the entire "getting started" bed leveling process, but there has
to be a quick way to re-zero things when you have to swap out the hot end, change nozzles, fix a clog, etc.
I've got Simplify3D, and I'm guessing that I could use the control panel to:
1) Under "Tools - Machine Control", jog the X&Y to the center of the bed
2) shut off the Z-axis motor drive, and manually raise the bed until the supplied feeler gauge is just touching the nozzle
3) force the Z=zero (?) in Simplify3D
That gets me close, but doesn't account for the thickness of the feeler gauge. There seems to be a major difference between the Z-axis system between the "D" & "E" versions. the "D" version used a limit stop at the top of the Z-travel, and on the "E", the limit stop is on the bottom of the travel. I don't even know if Z=0 is now at the top of the travel (i.e. when it hits the nozzle), or is now at the bottom. I'm guessing it's still at the top, but it's defined by the nozzle and set in software, rather than being mechanical.
So, what are the secret incantations required to do this?
Thanks!
