Custom printer. E3D 6lite hotend.
I'm trying to finalyl print and 2 weird things happen:
1. I configured the max temp to be 245 deg, but when I try to heat it through the menu it lets me heat up to 230.
Then I changed to 244 and could heat to 229. Changed configuration to 255 and could get to 240.
As I use 6lite and shouldn't exceed 245- someone know what the 15 deg difference is about?
(BTW, same thing happened with the heat bed. and same 15 deg difference)
2. I'm starting to print from card. The bed heat up just fine. The hotend heat up, get to the temp and then start "dancing" around the wanted temp. Sometimes gives me "thermal runaway", but I "fixed" it through thermal runaway configuration.
Anyway - it never start printing. It just trying to get to the temp all the time.
(Also tried to play with PID, but it shouldn't matter as the temperature somtimes get and even pass the wanted temp. It just doesn't print)
Any ideas?
