K1 + CFS - Not cutting PETG

Good day,

After I have upgraded my K1 with the CFS upgrade kit… i am experiencing issues with the cutter. It doesn’t seem to cut the filament when it rams against the cutting block. It does it a few times then fails and gives an error. I then manually switch the lever to cut the filament and retry… then the head gets rammed against the block again and the cutter doesn’t fully go back to the original position and fails again. Retry then sometimes it works and the filament gets retracted.

I have search the web to see if i can find an alternative solution maybe a different cutting block the is a bit bigger to allow the filament to cut properly with no luck. I have even thought of replacing the blade on the cutter, but its still brand new. So guess it couldn’t be that.

Any one else found a solution to this?

You need to readjust the cutter block or replace it. I had the same problem and replaced the cutter block. There is a video on wiki creality to replacemthe block.

I had the same problem I just replaced the entire extruder with one from Creality off of Amazon, as I was having issues with my extruded too. Seemed to do the trick

Also the latest firmware released a few days ago seems to have solved a good few issues also. Including multi filament loading before test extrusion. As this wasn’t working properly and would try to test extrude before loading filament
