Hi All,
Recently the RAMPS board on my PrusaI3 developed an issue with the heated bed not working. This later developed into the USB comms not working either, which was a problem as I use OctoPI. So I finally bit the bullet and got a new RAMPS board and Arduino Mega. I have chosen to use the current Marlin as I did not have a copy of the Marlin which came with the printer, I suppose I could have got one from the original printer supplier but thought I would upgrade to the current Marlin.
The printer is working but I keep getting issues with a "Thermal Runaway" showing on the LCD panel. I have managed to get a couple of prints without issue so the setup is generally working. I have done a PID auto tune and put the figures in the firmware but still get the issues. It is an E3D V6 hot end and I have tried the PID settings on the E3D web site and the results from the auto tune biut neither work. If I tell the hot end to go to 150 C and then to go to 200 C it almost always fails. It was all working fine befire I replaced the electronics. I have got another E3D V6 which I will try at the weekend.
Any other suggestions?
