Hi guys,
I have an Ultimaker 2 with the latest tinker software. I just bought a heater mat from Mcmaster (Part #: 35765K482 ), and I bought a solid state-relay from Digikey (Part #CC2108-ND). Everything works like it is supposed to, but with the "Bang-Bang" setup on the heated bed I am getting a lot of temperature variation, which is causing thermal expansion of my plastic. During prints the plastic would expand and shrink, which would cause layers to protrude outside the shell in a repeating pattern. (Please see the attached picture)
I know that it is the heated bed, because as soon as I shut it off completely the shell went back to a perfectly smooth wall. I have tried many different material, Colorfabb HT, Ultimaker ABS, Ultimaker PLA, and Matter Hackers Pro-series PETG. All of them have acquired this pattern ever since I changed the heated bed.
If someone could help me turn on the PID controller for the heated bed, and show me how to use the auto-tune, I would really appreciate it.
Thanks,
Andy

Ok! Thanks, again! You're right about the factory reset. I did that. Only because Cura wasn't able to upload the new firmware.
So, long story short: Never mind! 🙂 I'll leave the compiling to the pros and download it when ready. I'm done here. Have a good weekend!
