Welcome to the SeeMeCNC Community

I made some progress here today that will hopefully help. To use T1 for your thermistor, modify pins.h. Look for the section that says "#if MOTHERBOARD == 301". In that section, you will find variables named TEMP_0_PIN and TEMP_1_PIN. Change the setting of TEMP_1_PIN to -1 and TEMP_0_PIN to 1. That ...

Flateric, I measured one of the holes for my heating resitstors in my hot end. It measure about 6mm so I think the ceramic heating element you found on the seemecnc website will fit. I guess the biggest change is that I'll need to run four wires instead of two to heat the hot end. Still, that's much ...

I finally managed to make some progress here. The short of it is that two of my thermistor ports are shot, but I do have two that appear to still be functional. Here's the process I went through for those that are interested. First off, I'm using the Marlin for rambo firmware that was mentioned in ...

Would you be willing to provide links to the heating element and thermistors you are using? I really like the idea of reducing the possibility of shorting out those components.

Thanks for the quick reply! There's a lot of good info in those threads. Sad that I may have blown an input. I have a few ideas to try now. Thanks again!

Hi, A homing mishap eventually led to my hot end thermistor getting damaged. I was not able to detect any connection between the leads using a multimeter. My replacement will arrive in a couple of days, but I have a problem that I need to resolve before it will do me much good. M105 always reads ...

I just want to say thanks for posting this. I'm also quite new to 3d printing. I look forward to following your progress. Hopefully, I can learn from your experiences building it.
