Which bowden and collet/retainer for UM2 1.75mm conversion?
Posted: March 24th, 2018, 8:17 am
Hi all,
I would like to finally finish installing a 1.75mm extruder as a second extruder on my UM2. I have already installed the feeder motor, a mirrored version of the IRobertI feeder and a 1.75mm hotend. The only thing I am missing is the bowden from the feeder to the printhead. I think that a number of people here have converted their UMs to 1.75. What did you use? A 1.75mm bowden with special collets? A 3mm bowden with a inner 1.75mm bowden and regular collets? If the second option - how do you ensure that the inner bowden doesn't slip back and forth?
Hope you have some ideas to help me finish the conversion!
BTW: I plan to use only one hotend at a time and remove the nozzle from the unused one - both hotends have Olsson blocks installed.
