I recently purchased a Lulzbot Mini 1 toolhead on the cheap, and I’m looking to set it up as my dedicated 3mm toolhead on my TAZ 6 (which is converted permanently to 1.75mm). I printed the new mounts, fan ducts, etc, and physically it’s good to go. I moved the pins around the connector to match the TAZ 6, and it heats, extrudes, etc. From what I can tell it should be gravy.
It will not home the Z axis correctly. Normally, when it homes the Z axis it will home the bed first, which then moves back about 1-2" before the extruder is lowered onto the home switch. With my new extruder hooked up, the bed never moves back after homing and the Z-axis lowers onto the corner leveling pad instead. It is making contact and it’s seeing the connection since it does the quick down/tap/slow down/tap cycle like it does during leveling, but then just repeats this cycle over and over again. That’s all I get, and it just loops at this point.
If I plug in my original extruder, everything works perfectly without issue.
Anyone seen this before? Any thoughts? It’s really frustrating and doesn’t make sense. Thanks in advance.
