A while ago I posted about some problems I was having with my Up! Plus 2 3D Printer slipping throughout some prints (read the post by clicking here including how I fixed the problem). Well the issue seems to be back as you can see in the first image above. The first slip was quite small, so I let the print continue, but when I checked on the print after about 4 hours I found this lovely mess with 2 more slips.
I’m going to try the same procedure as discussed previously – cleaning the debris inside the arm that may be catching in the belt (controls front-to-back movement), and applying some grease to the silver rail which the print plate slides along. Hopefully this is just a continuing maintenance issue, and not something more complicated. Time will tell…

UPDATE 16/01/2015: After taking a closer look at the mechanism, I noticed a small tension clip interfering with one end of the gears. It’s just an overhanging piece of the wire, but when the print plate moves to the very back position it begins to wrap around the gear and this small overhang hits an edge of the grey plastic pictured below. I have used needle-nose pliers to bend this arm down slightly so that it no longer collides. Hopefully this will help reduce any print errors as well as the clean/grease mentioned earlier.
