Hey. So I have a new to me M200 Plus with a problem. At least one that I can’t fix on my own.
The temperature readings are way off. Even when the printer is started the hotend shows about 167 degrees an the buildplate 57 degrees. Both are heating when activated manually. Also I reseated and checked all the cabeling. I also checked the mainboard for burnt spots or anything off. I found nothing.
I also tried different firmware versions with no difference.
Also even when disconnecting extuder cable or heatbed cable the readings don’t differ and there is also no error message.
What can I check further? I won’t replace the mainboard of the printer as it is not anymore state of the art.
But I really would like to safe the machine from the landfill.
Thanks!
