* Removed the Nylon piece between the Fan Duct & the metal block to raise the duct opening a bit more. (In the hope that this would work better) | |||
* '''Carefully''' tweek the angle of the heatblock -- to get as much clearance for Fan Duct as I can. | |||
* Clear yet another Head Jam ... then the Thermocouple no longer works! (Head temp. always reads "off".) | |||
** At the Plywood of the Head, the Bowden Clamp is toooo difficult to get to release. (New clamp needed?) | |||
** I also seemed to have the Heater cable too tight to get the Bowden Tube totally out. (Problem from feeding more cable through head?) | |||
** We seem to be having '''far too many''' head jams with this printer. Does the PEEK and/or PTFE Teflon parts the filament goes through need replacement? | |||
** A separate 12V regulator & a PEEK Cooling fan ( https://www.thingiverse.com/thing:383950 ) should be installed for higher temp. printing. | |||
** And if this head needs to be rebuilt, then this ( https://www.thingiverse.com/thing:344113 ) using ABS looks like the best Filament Fan solution. (NO blocking head view/access, NO turning Heatblock, etc..) | |||

* Replaced filament cooling fan duct w/ https://www.youmagine.com/designs/tapir-shroud-for-ultimaker ... printed using PETG | |||
* Had to '''carefully''' rotate the heat block about 90° to install that. | |||
** Had to feed a bit more wires through wooden printhead to get slack to do that. | |||
* Resorted to using tie-warps to get this on/installed. | |||
** A piece of (nylon) tie-wrap was put between the Metal printer plate & this part, to prevent warping due to heat. | |||

* Replaced the filament cooling fan duct for a 2nd time. (Heatblock burned through it.) | * Replaced the filament cooling fan duct for a 2nd time. (Heatblock burned through it.) | ||
* This '''large''' cooling fan shroud now is '''extremely close''' to the Printbed ... which produces excellent results, but makes it incredibly difficult to catch the loose filament when a print first starts. (Filament trapped next to the printhead causing prints to fail when first started.) | * This '''large''' cooling fan shroud now is '''extremely close''' to the Printbed ... which produces excellent results, but makes it incredibly difficult to catch the loose filament when a print first starts.
