Finally got some downtime between projects and have installed a new Micro Swiss all-metal hotend for my Ender 3 Pro. (also switched to Capricorn tubing) The install was pretty straightforward, and I followed the video instructions on the Micro Swiss website.
I had to adjust the z-stop slightly upward and after a quick re-level it seems to be working great. The 20mm XYZ cube came out very nice. I'm going to run another complex print test, but so far so good.
At the end of the install video, Micro Swiss suggests reducing the retraction to no more than 4mm -- easy enough.
They also suggest keeping the fan on 100% at all times, which raises a question. I'm printing PETG, and my current settings are:
0 fan for the first 3 layers
Regular fan speed 60
Max fan speed 80
Initial layer speed 20 (for 2 layers)
Print speed 40
Extruder 245, Bed 75
Initial layer height 0.3
I'm thinking they meant the advice to keep the fan on for printing PLA rather than PETG. Can someone give me a sanity check on this?
Thanks in advance!
