Re: Temperatures do not update when Heatbed turns on - 11 years ago
@Nick: Is this your Hotend? It's still seems that your Hotend is equipped with a Thermocouple, which needs to be operated differently than Thermistors (It needs an Amplifier) see here The Repetier Software seems to save all configurations inside the program itself instead of being defined in the marlin configuration.h (referring to this)) I'm sorry I can't help you out here but I suggest to justby Garfiled - Reprappers
Re: Temperatures do not update when Heatbed turns on - 11 years ago
Problem Solved Thank you very much guys! I tried a 47Ohm Resistor on the 5V rail but it got unpleasantly hot. So I hooked a 5V Servo to the rail and tried to power the Heatbed with success and remaining serial connection. The crazy thing is that the voltage still drops to 10.76V when powering the heatbead but the serial connection doesn't break and the desired heat is achieved quickly. When I gby Garfiled - Reprappers

@Nick Hi Nick, The Thermistor on my E3D V6 Hotend says to be a 100k Ohm Semitec so I chose option 5 (the only Semitec with 100k). in my uploaded config.h its is mistakenly valued 1 The Thermistor from the Heatbed just says 100k without any specification so I chose option 1 since this is usually delivered with the MKII Heated Bed. Which Hot End do you use? @plankton I will try that out, thanksby Garfiled - Reprappers

Hey, thank you for the fast reply I'm using the Printrun Package from 10.03.2014 and Marlin version 1.0.1. The Configuration.h file from Marlin is attached Edit: Just found out via the debug option in pronterface that the printer stops sending the basic information as soon as I turn on the Heatbed By accident I touched the mosfet for the Heatbed and it was smoking hot (burnt fingertip).
