On TAZ5, TAZ6 and TAZ WE (RAMBO controlled) with the half height motor aerostruders (SE, SL, finch) we are getting overheating extruder motors.
In a well insulated enclosure at 42C ambient, which is about where the cluster is running, i measured the temp of the extruder motor with the FLIR to be about 95C.
@david.hall mentioned the motors on the redgums in the cluster were running at about 93C
Over an extended period of time this high temperature will melt the motor mounts and fan shrouds (T8313)
On trinamic drivers we are limiting the current to these motors at 960mA
On the Rambo drivers we are running them at 1250mA
We will need to adjust the motor currents down to 960mA on all firmwares for all half height motor aerostuders.
