Strange, I had upgraded my original printer-head with an Olsson block a while ago without any firmware update and hadn't had problems. Guess I got lucky. It is doing way better to try and stay within' the mark (10 degree fluctuation instead of the 30 degree). I'm going to try a print and see how it goes, though the fluctuation still seems a bit high. Thanks again!

Hey guys So I'm trying to do a PID auto-tune and I'm getting the error of the auto-tune failing due to the temperature is too high. I type in "M303 S215 C10" into the Repetier command g-code area and it starts, I watch the temp rocket past the 215 target but under the max of the extruder and it cancels the auto-tune. I'm trying to look around and see what is wrong, It seems like some kind of power output problem from the posts I'm looking up but it's getting so advanced so fast I have no clue what to google for that's comprehensible. Additionally, I've tried updating the firmware of the printer to UM2+ and it just becomes unresponsive. So I have to revert to UM2 Firmware. What should I do next? Any possible links that may help me comprehend some underlying factors so I can better wrap my head around troublshooting this?

I replaced my original print head on my printer with the the closest model available (Ultimaker 2+), I'm not sure if they're is anything different but now the hot-end has serious trouble maintaining a steady temperature, causing ribbed edges on the sides of prints. When a print begins, it does a massive spike (35+ Celsius over setting) and then continuously fluctuates around 10 under to 20 over the mark. I checked the motherboard and the connections seem fine. I've never done any update to the printer, simply changed out the print-head. Anything I might be missing?
