I’ll try describe my issue if I set the tempurature with pronterface to 200º the temperature never reaches that value for instance it almost target that tempeurate 196/197ª and then start to drop to 184/85º end then start to raise again to the 196/97º. And remains in this loop forever, I’m not able to start any print because tempurate never stabilize.
I’ve try to configure the PID (M303 E0 S200 C8) with 8, 12, 15 intervals not help the issue continue.
I’ve try to change heatblock and termistor not help
Its important to refer this behaviour occur in any tempurate if I fix 150º it never reaches 150º it go to 146/147º and then drops again 10/15º and restart the loop. Same thing if I fix the tempurature to 210º.
Also I’ve tested this in multiple versions of marlin 1.1.8 and 1.1.9.The version of marlin 1.1.8 have worked in the same print in the past.
I’m have not clue about what can cause this issue, maybe its a board malfunctions (mosfet) or a powersupply malfunction.
Somebody can help me on this?
