I recently bought the DXC2 Extruder because I really liked how quickly I could access the extruder's internals, and because I'd heard great things about its quality. Of course, during my research, I saw people were having various issues, and to be honest, I expected them. It's a modification, and with that comes compatibility challenges. What I didn't expect was spending a full 2 weeks trying to resolve the DXC2 not cutting or retracting the Filament when loading, unloading, and during CFS Filament swaps. Other than that, it works amazingly, just not the way I need it to lol

As a starter note, I have reached out to Phaetus and been in communication with them for about 4 days now. Their support is super responsive, and they have been really trying to help me, so I am grateful. In addition, when I bought the DXC2, I also upgraded my hot end to a MicroSwiss FlowTech CM2 - .4 Nozzle and did the proper calibrations and print setting changes, so I cannot see why this would be causing my problems since it did the same thing with the stock hot end my K2 came with!

All 4 of my CFS slots have issues retracting filament during color swaps and throw error code FR2865: Feed Issue, Filament Failed to exit Extruder. At this point, it forces me to retry the retraction process/ Cutting for it to finally work (it always exits and retracts on the second try). This sent me down a spiral of changes and checks to my CFS PTFE feed tubes, gear system, cutter, literally everything.

In addition, I:

Added 1 mm extension to cutter probe
Played with my Cutter pos/ offset values, as well as adding a pause during the cutting process
Retraction speed & Distance
Extrusion Temp/ Velocity

Plus many more backend tweaks....

All of these yielded nothing but more failures and, in some cases, other issues, so I stopped messing with them and did a full reset of my printer to factory settings, only changing the required DXC2 Values in Fluidd.

Tomorrow I plan to flip the magnet on the DXC2 backplate and swap the DXC2 Filament cutter for the Stock Creality one as my last go at it before I wait to see what support says now, or I just go back to stock.

If anyone out there has any tips, tricks, or advice, I would be happy to share more information and try anything to get this extruder working... There has to be something out there that can fix this!

Thanks in advance to anyone who can chime in!

So I’m fairly new to 3D printing and it’s been about 1 month now since I purchased this A1 Mini. I have read the maintenance guide, done research to make sure I’m properly using the printer, and am keeping up with regular maintenance.

I’ve done many prints on this A1 already but this is the first time I have heard this sound so I’m not sure if it’s normal.

I checked the rails and made sure they were properly lubricated, the tool head is perfect, and I’ve calibrated the printer just to be sure.

I suspect this is the Y-Axis timing belt, but before I go taking this thing apart I want to be sure and get some opinions & feedback😅

My prints are not compromised or causing any sort of errors, but the sound is annoying and if it is something that needs to be checked and adjusted, I’d rather do so!

Thanks in advance for your support!

The DXC2 is driving me CRAZY!

My new A1 Mini is making an odd sound.. what are my options here or is this normal?
