Would it cause it to jump at a specific temperature every time? You'd think it would be at different random intervals, but it jumps to the from and to the same temp every time. I think it's the controller, but I also don't know much about wiring.
It prints... can't complain too much. I just really wish there was support for this ANET board. I've seen one other person with this exact issue on another forum and he had the same board and issues.

I have the same problem. Anet A8, Repetier Host. Bed temperature always jumps from 83C to 95C and back, it looks like there is only one degree between 83 and 95 somehow...

Check the temperature file.
As a practical test. Set the bed temp to 100C so it forces the heater on at 100% up to 100C.
Look at the temperature profile in repetier. The temperature should rise smoothly. You will see where an error in the table causes the reported temperature to change the slope of the curve.
This is repeatable because its a reporting error at these specific thermistor values.
In the OP you see this happen just after 57m at ~ 83C.
Interestingly the heater is not turning off until 58m so the bed control is working OK its just the temperature reporting that's the issue. I don't know how that can happen as they must use the same table. I can only assume that when calculating the target temperature its using a different algorithm.
Hopefully there is an attached example of the temperature file (not the one for your machine).
