@Bill thanks! Do you have a link to the compression fitting, so I can order one?

Hey @Bill - I had couple of the PFTE tube pop out of the 3D Chameleon. I disassembled it to put the ferrules back on but couldn't get the originals back on the PTFE. I ordered some new ones and they arrived today. Do you do anything to help keep them on the tube once installed? What keeps the tube from sliding out again?

I may have just answered my own question - in looking at my printer's firmware, the manufacture set the DEFAULT_STEPPER_DEACTIVE_TIME setting in Configuration_adv.h to 5 seconds!!! (default is 60!). It looks like I can fix this either by editing the firmware (still not quite comfortable with that - don't want to brick my only printer), or via G-Code with the M84 command and an S parameter to set the timeout. For example; M84 S300 would set the motors to disable 5 minutes after the last move.

I see. I have all-metal MicroSwiss hotends, so I guess there is no where to install it... unless it is meant to go between the MicroSwiss and the BMG? Thanks!

Thank you Bill! One last question (for now ;-) ) - there is a short piece of PTFE in the parts bag that seems to be a tighter tolerance than the rest. Does that go between the 3dC Y adapter and the BMG Extruder? or does it have some other purpose?

Ok - thanks for the honest insight. I've ordered a BMG extruder to see if I can fit it to the E2 on the printer. If that works, then I'll be back here to order a Chameleon.

Hi Bill - I think I was editing my post and you were replying. I also have Titan Extruders. Should I be rethinking this? The the FAQ you mention an alternate "Advanced Extruder Replacement" installation method documented here: https://www.youtube.com/watch?v=GaWiYqWP_s4&list=PLs1jpNL7rg78Bm6cDAC4JwaUNlpFa6UEf - but this link doesn't work. Thanks!
