Welcome to the SeeMeCNC Community

Hi all,

I have a SeeMeCNC Orion Delta that is still fairly new. The total print time amounts to 8 days worth, and the equipment is in good repair overall. Out of the blue, my printer no longer will heat up in order to print. I will set the target temp to over 210* C and it will not break past 190*C... and it takes a while to get there. I'm not sure what went wrong, but I am wondering if there's something awry with the thermostat / thermistor? And if that's true, how can I even identify that piece in an effort to troubleshoot / resolve the problem? I think that the issue should be minor, but I am learning about my machine so I'm not sure with where to start.

Thanks for your help!

Using a digital multimeter, I would measure the resistance of the heater. I'm sure someone will chime in on what the resistance of two of the resistors in parallel should be.

Which hot end do you have on your printer? Is it an HE280 with the accelerometer probe? Or the old peek hot end that you have to calibrate manually?
