I recently inherited support for our two Taz printers, one being a Taz 6. It does not auto-home properly, failing consistently on the first washer. I’ve checked x-axis alignment (Step 23) and have cleaned both the washers and the head. There is something I’d like to check with the community, however, since I think end users might have tried to monkey with this printer.
I’ve been trying to figure out from video pictures where the 5v sensor for auto homing connected to the print nozzle. I screen grabbed this image:
Seems like the 5V sensor attaches via a screw on the opposite side of the power cables?
On our printer, on the right side of the nozzle (from front) there are two red power connectors and a black cable that goes somewhere…
On the other side, where I believe the 5v sensor attaches, I’ve got an empty screw receptacle above and slightly forward of a metal protrusion.
I’ve scoured the wires coming from the extruder cable set and can’t find a free cable in the set. I’m wondering if someone before me put the wrong cable in the wrong place? I’ve removed the right side fan, airflow cage, and then loosened the clamp near the power connectors, but that black cable looks like it goes right into the nozzle and might be in the right place (GND?).
I wonder if my 5v sensor is not attached, therefore it can not auto-home?
Thanks for the assistance. Coming up to speed on this printer as fast as I can. I have pictures of my nozzle but can’t upload because I’m a new user.
