Is anyone having issues with getting MPC Autotune to work on an Ender3Pro v4.2.7 w/bltouch and stock hotend?
Everytime I try to autotune it stops at first attempt ramping to 200C

I can’t figure any reason for it to not work. I’m using a custom build made with the firmware builder (tried today’s build to be sure it wasn’t a bug already patched) and although it does seem to print okay and the ramp up is nice and free of ringing I can’t get the autotune working.
When first trying it out I didn’t set my heater power and just tried to autotune. Today I read I was supposed to set that heater power (M306 P40) but it didn’t help with the autotune.
Am I stuck tuning it manually?
