Itty Bitty Double Extruder

Issue a G28 then G29 manually and see if it completes the routine.

It does complete both routines. On G28, it moves to X, Y, then near center of bed and Z. On G29 it maps the glass in a 3x3 grid and retracts the probe, leaving the extruder in the last position of the test.

For my Start G-code, shouldn't these commands occur after the bed and hot ends are heated to allow for proper thermal expansion? I see that Clough's code appears to accommodate for this, but I'm not able to get a print started with it yet.

Edit: I just successfully started a print. It's still a bit too high off the bed, but at least it's trying to print ON the bed now. I *think* disabling the eeprom commands helped. Will keep tweaking.

Yes your start G code should heat first. Ill post my start code later when I get home.

What did you insulate them with?

I first sprayed the servo wires with Super Shield (Nickle conductive coating) then i wrapped thin strips of adhesive aluminum foil tape around them, seems to have helped

the Super shield isnt cheap ($30/can)

Yea! Looking good....

No matter what I do, I can't get the hotends level...my right side Z-nut spins itself out of the nut trap by the time the right side hotend touches the paper (see gap on right side in photo). I'm at a loss...

Sounds like you have a Z axes bind remove the rods from the motors and make sure your Z has no bind throughout the entire range.

Sorry, I'm a little dull sometimes. Can you elaborate on what you mean by making sure there's no bind?

I'm assuming I should discconnect the threaded rod from the motors, then run the z-nuts up and down the threaded rod to make sure they don't hang on the threads?
