So I got me a Slice Engineering Copperhead a while ago from the Kickstarter campaign (https://www.sliceengineering.com/pro...rhead%E2%84%A2) and finally got around to installing it to my Tronxy X5S. I got the groovemount variant of Copperhead, which is almost a direct swap for E3Dv6, although I had to do miner modifications to my E3D Tronxy mount (https://www.thingiverse.com/thing:3312783).

I also needed to design a part cooling fan setup since the previous part was designed for E3Dv6. The mount allows swapping the fan ducts so I can revise the design, current one isn't optimal because it's one side only (https://www.thingiverse.com/thing:4793026). I printed the mount and duct with GreenTEC Pro which claims to withstand temps up to 160C.

The thermistor is the 450C version, not sure if I ever need such high temps. Configuring Duet was easy once I found the proper values for config.

Initial test with PLA were stringy and after some tuning couldn't get rid of it. Tried tuning retraction and temperatures to no avail. Might be because of the oncluded 0.4mm vanadium nozzle. Luckily the hotend supports de facto E3D nozzles so I can swap in basic brass nozzle. PETG with 0.6mm brass nozzle produced quite nice results so I'll test PLA next.

Haven't done any multi-material printing with the new hotend yet. Interested to see how the bimetallic heatbreak affects the tip formation, would think that the sharper temperature difference would help with stringing.
