My printer [A Tiertime UpBox+ with an enclosed and heated chamber] had a problem with a Y Axis layer offset that ruined the print.
Examination of the printer revealed the Y axis belt was loose.
This was due to the Plastic Bearing support for the Y Axis drive shaft had broken. This is a known problem with this and similar printers in the range.
The previous owner had reinforced the supports with a 3D printed cover. However the Left hand support had completely fractured into 3 bits. The Manufacturer has these plastic supports available for ~$3 from China ... a 2 week wait !
Since I have modified my printer to keep the enclosure temperature up to around 60-70 C to prevent ABS prints distorting I decided that the Plastic bearing supports should be replaced with something a little more substantial in Aluminium.
I removed the 2 supports and measured up the good one, fortunately the dimensions came up to whole numbers so machining was going to be a bit easier. A Tee slot cutter was used to cut the recess for the bearing
After a couple of hours on the milling machine and a bit of fettling with a file and emery cloth I had a working machine again.
