When I press the switch for one second there is a horrible grinding noise from the stepper motor in the 3D chameleon. Is this normal?
When I tried printing, the firth thing that happens is the grinding noise, then the chameleon unloads one of the filaments so that it ends up far away from the y, then the printer starts "printing" with no filament loaded. I used the gcode generator. Not sure what else to do other than perhaps changing the code to press the switch 3.5 seconds to load instead of 5.5 seconds.
The grinding noise is a concern.
Does anyone other than you have this thing working? I have a brand new ender 5. The only modification I made was to buy a BMG clone (on your suggestion) and I installed it on top of the hotend in a direct drive configuration because I figured that would reduce the load/unload time. Perhaps I need to go back to an all stock setup - move the extruder back down to the side and reinstall the Bowden tube just prove that this thing doesn't work, even when I set it up just like yours in your Ender 5 videos.
Even perfectly shaped ends are hanging up at the bottom of the Y nearest the extruder. There's something wrong with the design. The compression fittings on the Y are just loose in there. Would have been better if that thing was one solid piece with no internal lips for filament to get hung up on. I now regret having made this investment. I need to take a break from this so that I don't end up taking a sledge hammer to my printer. I'll try again in a few days. If I can't get this sorted soon, I'll just ship all this crap back to you for a refund.
Multi colored prints are not worth this.
