Hello guys, just wondering if it's a standard behaviour... but when I set the Hot End Temperature of my Prusa i3, let's say at 195°C,
it ranges between 194 and 198.
You may have some electrical noise causing this, or some other cause for this abnormal behavior. The normal variation is +/- 1C. Try to twist the hotend thermistor leads or shield them from the stepper wires and make sure you have the PID parameters in the firmware correctly configured for your 3D printer.
