Today I just found out that typos in your C-Code sometimes can be lethal.
e.g. if you type a 61 instead of a 60 for the maximum number of values in your array,
your µC might just hang and melt down your PEEK heat stopper.
I've already ordered a new hot end.
Hopefully it arrives soon.
In the meantime I'll optimize the way, R2C2-Firmware manages the heating.
Because there are more efficient and stable ways to do so...
