Hi, This one's beyond me at the moment engineering wise, but might be worth thinking about... When I was a kid my microscope allowed me to rotate a lense carousel which clicked into place allowing each lense in turn to be aligned under the eye piece & allowed it to be out of the way when not in use. The carousel was cone shaped so that the unused lenses would always be above the one in use. I was thinking how this might work for delta type robot effectors where the filament tubes would travel as a bundle. I was thinking that the heads could be stepped into place with two solenoids rotating the carousel in the two required directions so that it could unwind. The benefit being that each head would sit in the same position when selected & be above the print area when not. A common fan could cool the assembly & heat to the individual heads could be maintained throughout or switched on or off by aligning selection contacts. Has this idea already done the rounds? If so, my apologies I can't have read far enough. https://reprap.org/forum/read.php?88,367658,367658#msg-367658 Sat, 06 Jun 2026 00:55:54 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?88,367658,532241#msg-532241 https://reprap.org/forum/read.php?88,367658,532241#msg-532241
Using stepper motor are good for accuracy but the body are too big to make it compact, I guess a servo much better so the bowden tube won't get tangled since servo has rotation limits and its center too

Try imagine most dual extruder/hot end mount design in bowden, switching places each other, no compromise on print volume (but watch out on bulldog clip or something =)]]> sarf2k4 Let's design something!

Different nozzle diameters? A lot of work for a switch in accuracy.Is it really worth all the work?]]> Lykle Let's design something! (I've got an idea ...)

i'm very interested in this since it (and maybe some other configurations for multi-hotend) would allow for a single calibration point, which from my experience is the only way multiextrussion can be properly done in a delta
