Hi All, 

I'm struggling to get the CRX to work for me. I am printing PLA at 200Degrees and 60Degrees on the build plate which is glass with glue stick. I believe it may be heat creep that's causing issues. I have the stock fan on the heat sink running at 100%. The print starts off well, but then flow stops as per the image. The extruder drive starts to knock and then when I open it up there's a good size plug, I'm sure this is the reason for the print fail. Could I have any suggestions to help out the troubleshooting process?

I've had the same issue on my Ender 3V2 before, and it turns out that there are some connection issue on the fan: it stops to work after a while and causing the clogging. Thus, I was wondering is the same problem happends to you as well.

as mentioned above, it's highly fan related issue..

Is your side fans working?  I had similar clogging issue when my side fans are not working.  My hardware and material is different thou.  Ender5+ and PETG
