I can not get through one dam print now without error “FB2846” 20 fucqing times and I don’t understand why.? Because there is no tangle in the filament. I changed the nozzle because I thought that was the problem. But it wasn’t why is this now a dam persistent problem?
Hi! I’m sorry that you’re experiencing this problem. The issue is probably not related to the nozzle. I found another possible solution on the Creality Wiki - FB2846 | Creality Wiki
You can try those steps, and if they don’t help, you can contact Creality After-Sales Support — they are very helpful.
Here’s the link to the support contact: Creality Aftersales
Let me know if you need more help in this case 
Thanks for the reply, it was the heating bed. However I think I found a workaround that has been working for the last few prints. I had to pre-heat the heating bed to 84 degrees before I start a print. There for eliminating the wait time all together.

Did this sort the issue for you? I keep getting it mid print.
im sure this is related to bad spools not rolling properly on the CFS unit
That’s what I thought but it’s random. I’ve printed from the same spools up to around a week ago and then they started failing.
There’s no pattern to it.
what size spools are you using
Check if anything is blocking the white roller that spins the spool inside the CFS—like a piece of filament, a silica gel bead, or something similar.
