We just purchased 2 new TAZ Pros and have 4 other TAZ6s in our inventory. On one of the TAZ Pro’s the 2nd extruder will not lower. We have tried printing with it and it does print but from the upper (i.e. not lowered) position which is clearly not correct. We did a quick inspection and could not find anything immediately wrong. I have opened a support ticket and we have been dragging our feet a little bit since the other TAZ Pro appears to be working fine and I have 20+ other printers to maintain, but now with the pending Aleph problems, I am very concerned about getting help before help is no longer available.
Sorry I have not done more troubleshooting, but I will this week. I am just hoping for a quick point in the right direction. Thanks in advance. You can find out at: www.makerspaceusna.com
