Anet A8 ignores extruder temperature? I don't understand what's wrong with my G-code. I have set the printing temperature to 195 °C but when I try to print, the target temperature is always 0 °C and printing never starts.

I have tried changing material preset to different PLA profiles but that didn't help at all.
G-code:

In addition, the extruder and heat sensor are working. An older G-code file correctly sets 200 °C as the target temperature for the extruder.

This G-code prints just fine

Note, I have never modified the firmware or changed anything except what I can change with the frontpanel.
There is nothing wrong with the G-code, M109 S195 sets and waits for the temperature to reach the set point. There must be a different reason, other than G-code, why the temperature is not set correctly.

After updating your question by adding another G-code script, the conclusion is that there is nothing wrong with the G-code itself. The problem is that the printer cannot set the 195&nbsp;&deg;C temperature.

Could it be that the minimum temperature is 200&nbsp;&deg;C and that it doesn't set a temperature lower than the minimum value?

If you are comfortable enough to flash a new firmware (which you should always do with an Anet A8 as it has no thermal runaway protection) you could try to see if this is a firmware problem.
