So upgraded a taz 4 from a Buddha to a All metal with the following shroud:
The problem I am running into is that the fan pointed at the cooling block is blowing very slowly. It appears to be plugged into a PWM pin, but setting #define EXTRUDER_FAN_SETUP 4 to 3 or any setting doesn’t allow me to run gcode to adjust it.
Meaning, once I turn on the machine, the fan goes very slowly. Trying to adjust it with M106 S255, M106 P0 S255 or ANY P0 setting, only adjusts the fan on the right (parts fan). Nothing will even adjust the coolblock fan.
What am I missing?
I upgraded firmware to the latest, and had a lot of problems with LCD stuff and other random things to adjust.
left – hexagon always on cooling fan - cannot adjust it and runs too slow - have to flick it once to get it going, barely turns
right – parts fan, only fan that is adjustable via no p setting or p0 p1 p2 etc for M106 Px Sx commands.
sorry for the bad lighting, but you get the idea. Followed verbatim the upgrade instructions provided on the website.
