I really hesitate to post a problem here as I've been printing with my Ender 3 for over a year now with few and minor hiccups (and it running often for days at a time) but I recently replaced the entire hot end an am having issues with the print quality since then. Over the last week I've calibrated the extruder, increased/decreased the flow rate, increased/decreased the temp (nozzle and bed), increased/decreased the printing speed, changed filament rolls, and leveled the bed several times and I just keep getting a super rough, uneven finish on my prints. Before I start taking things apart, I thought I'd run this by you all and see if anyone had any thoughts. I'm going to replace the bowden tube and nozzle next (even though they are new), but if I'm missing something obvious I'd love some input. The bottom looks better but also not great.
