Came well packaged, on first couple of prints no problems at all. The started getting problems with longer prints, turned out the motor being used got very hot, very quickly. In fact that hot, it melted the PLA outside of the tube and caused a failed print. After stripping down and unblocking the PLA, a small amount had damaged the feed tube but I managed to correct that. Only was to solve problem was to change motor for a better quality one. Currently ran several 20+ hour prints without problems.
When the hot end came, I stripped and fitted the unit to the printer. Looked the part... the Pinda Probe was ok, worked on my aluminium bed. Initially the prints were ok, only small short runs 10mins - 1hr. So I decided to do a bigger print - about 6hrs, it managed to do about 4hrs and the filament jammed, which I have never had. Cancelled the print and found to my surprise after burning my hand the motor had cooked it self and was that hot it melted the PLA on the gear. My previous motor got warm but that was it... never that hot you couldn’t touch it. Stripped the unit off and disassembled to change motor over. That’s when I noticed the heat block had melted the bottom of the case where it was touching!! Which in turn had melted over the block and was transferring to the print jobs in forms of black burnt PLA. I thought I had a problem with retraction setting at first, blobbing. I rebuilt and printed new case then transferred all again with new heat block & silicone cover.
