Reply To: MK9 Extruder



I think you might be right with the temp, I have a thermocouple on my DMM I’ll confirm the temp.

I thought the stepper was feeding too fast, as after a couple of MM it starts to skip on the hobbed gear and when you stop the feed the plastic continues to extrude from the nozzle for quite a while, now I think about it if the temp wasn’t hot enough this would happen too.

I’m using thermistor #1 in the Marlin firmware which is 100K 4.7K pullup, I don’t know what kind of thermistor this is though due to the dodgy chinese ebay listing. Which setting are you using in Marlin?
