Yaccomod - Yet Another aCtive Coolment MODification for the M200 extruder gear

thingiverse

The extruder gear on the M200 gets hot and when higher temps are used, with side panels or covering the printer, the filament is softened to a degree that extrusion stops because the gear has no grip anymore. Higher ambient temperatures can cause this issue as well. The filament can be pushed into the extruder by applying a little force, but it's not an ideal solution. The extrusion stop happened frequently for me when laying the raft, which is done by the M200 software in a non-optimal way. It also happens after changing to Hotend V2 nearly with every print, and sometimes during a print if temps are even higher. There is another variant of an active cooling mod on Thingiverse that solves this issue. I call mine the poor man's version because it works very well. The mod consists of a printed cover, an XHP-2 socket/jack extension for connecting the fan to the upper fan of the printer, and 4 sets of M3 screw/nut/washers. The fan used by me is a 40x40mm 12V type, which I actually ran at 15V but it worked fine. The original extruder cover is removed because I use a Z-Temp, and the mod is put in front of it. Getting the filament through the cover can be a bit tricky if it's not straight, but it's not a problem. The cover was printed flat with a 90-degree rotation at X, using Z-ABS, .19 layers, solid fill, and support light at 10 degrees. Update: The mod covered the Z-Temp that sits behind it and also the colored real-time temp status display of it. I did another print with NuNus transparent ABS, same ZCode, -20 degrees offset at Z-Temp, and now the cover of my mod carries the colored temp status of the Z-Temp.
