Quite a lot of work over the last few days partly necessity and partly for convenience.
The function selector was faulty, so needed replacing. This required removal of the front panel, so this was an opportunity to fit a 3D printed mount to angle the panel upwards by 45 degrees, making it much easier to see. At the same time I replaced the control knob with a 3D printed raised knob which is much easier to use.
The extruder fans were getting noisy and running unevenly. The nozzle heights have been uneven from new; it's necessary to remove the fans to adjust these. If there's a blockage it's often necessary to remove the fans to deal with it. Removing the fans required the removal of 8 dome nuts and then the fans had to be slid off their mounting pins, made difficult because their wires were too short to allow easy removal. In short replacing the fans was an opportunity make other tasks easier.
So, it was off with the old fans and new ones fitted with longer, rerouted wires. I fitted 3D printed fan holders that the new fans just slide into and whilst the fans were off adjusted the nozzle heights.
It didn't stop there. For some reason instructions sent to one extruder were being duplicated by the other extruder, making the use of dual filaments impossible and having double extruders pointless. I've tried time and again to resolve this through printer and slicer software settings without gaining anything other than the knowledge that this was a printer fault. Well I went for a factory reset in the hope that it would fix the problem; it did, yipee 😀
