Perhaps it doesn’t matter now that you’ve moved to marlin, and perhaps there is some information I’ve missed since i didn’t read the whole thread… but.
In your config you’ve got the following settings which seems way off to me;
That’s 60000 mm/minute or 1000 mm/s. 1 meter per second. It’s insanely fast. Try something like 5000
Strange value but i don’t know your hardware. Have you checked prusas reprap calculator?
Not a big issue though, printer would still work but your distances would be off.
Once again an insanely high value. A Prusa i3 or ultimaker has ~1000. A well tuned CoreXY can do 3000-5000 and produce good looking prints. I’d start at 1000 and work my way up if I were you. Try printing a few ripple tests to see what your printer can handle.
I’d start with 0.05 which is the default setting in most configs and work your way down from there.
Why such high values? I’ve limit my printer to 30000 for X/Y and 600 for Z I can assure you it’s fast enough.
Once again. Why the high value?
I’ll eat my sock if your extruder motor can handle that acceleration. Try 100 and work your way upp.
Seems quite high. You sure your stepper motor & driver can handle that?
I run my extruder at 0.5
" # PID configuration" (had to use " " as the hash sign or whatever it’s called makes text bold here)
All your PID values are commented out with a # at the start of the lines. As far as i know PID is required for the hotend to work. But perhaps you’ve got it in your override file?
Your printer looks like a CoreXY to me but you haven’t enabled CoreXY homing;
I’d recommend you go through each line of your config and read up on it on the smoothe wiki.
They also have good starting guides for 3D printers.
There are probably more errors in there. Perhaps the wrong pins are used for example, have no experience with the MKS.
