I am using 2 Heaters
Heater6 = 150W
Heater7 = 100W
I am using it through Duet Expansion board (PWM Heater)
I have tuned it several time. but it is getting out of control temp increases or decrees by 15C.
here is my setting.
M307 H6 A113.8 C160.0 D49.5 S1.00 B0
M307 H7 A280.4 C232.7 D30.4 S1.00 B0
M570 S240 H6 P40 T25
M570 S240 H7 P40 T15
My PT100 sensor works fine when i start a machine.
But when i shoot Extrude Command or Retract Command then temp. goes to 2000C
The same configuration works fine with thermo couple.
Do you mean the breakout board gives out pulse of 5v?
