Changed the hot end? Like just the brass nozzle tip? Or the what?
Either way if pla isn’t printing below 220 I’d start with a pid autotune. This will let you see if the hot end is actually doing what it should.
This site:
https://teachingtechyt.github.io/calibration.html
Has all the steps for tuning a printer, pid and e steps are listed. It’s worked well for me on my old Ender3 Bowden drives and many of my newer direct drive ones.
What printer do you have?
To your printer.cfg I’d add:
[exclude_object]
Allows you to cancel individual items. If you have multiple items printing and one fails in one way or another you can cancel just that object and continue the rest of the print. Literally the only thing is add the bracketed thing to the cfg and it’ll add a icon next to the pause button that gives you the options.
Meh on the next part. I see that version doesn’t have bed level knobs. I’ll leave it if there is someone else who doesn’t know about it.
I’ve also found that one of the bed screw leveling options is very helpful for getting the bed close enough for the bltouch to really be dialed in. I use
[bed_screws] Screw1: 32.5, 202.5 Screw2: 32.5, 32.5 Screw3: 202.5, 32.5 Screw4: 202.5, 202.5
Then in the console run: bed_screws_adjust
Just moves the nozzle to each of the four corners right above the leveling knobs. Makes it pretty simple. I will add that the coordinates I use are fore a ender3pro but should be the same ish for you. But don’t quote me on that.
