why did my Printer melt?

@dc42 I should also mention that everything worked fine before the convertion to RRF3.

I very much doubt that it is related. If all the heaters turn on when you power up with no SD card inserted, then it's definitely a hardware fault.

every heater output is set to 100% at startup?

Every heater was on full power at startup?

Yes

correction not every just Bed and E2 E3 and E6

@dc42 I corrected myself it's only Bed, E2, E3 and E6

I now checked it and without the sd every heater is off

@Killernoy is it because you have inverted your heater pins?
Try removing the ! From each M950 command and try again

I will try that tomorrow thanks

I miss a few things in your config:

PID settings
Max Temp protection (M143)

Also the bedheat, e0heat and e1heat do not have to be inverted on duet2. If you do, then the heaters are always on.

The two heaters on duex5 a correctly that they have to be inverted.

According to you config there is no E6. You just have defined four extruders.

I also noticed you have defined

M950 H0 (Bed)
M950 H1 (Tool0)
M950 H2 (Tool1)
M950 H3 (Tool2)
M950 H4 (Tool3)

but you create tools with:

M563 P0 H2
M563 P1 H3
M563 P2 H4
M563 P3 H5

So the heater mapping does not match. That means if you gcode tries to heat up tool 1 it will heat up tool 2.

So your config is really confusing and I think this is the main reason why something is melted. The looks like you have done some mistakes while conversion to RRF3.

You can look at my config how to define 4 tools (I just picked the lines which are related for the tools):

This looks like a winner. Like swapping the gas and brakes pedals in a car.

Although that will work, if you are using a DueX to provide heaters 3 and 4 then I would use this instead:

M950 H0 C"bedheat" T0
M950 H1 C"e0heat" T1
M950 H2 C"e1heat" T2
M950 H3 C"duex.e2heat" T3
M950 H4 C"duex.e3heat" T4

You don't need to invert any heater pins if you use the actual pin names that you connect the heaters to.

I´m going through the configuration tool in order to avoid any further Problems

Thanks again to everyone that gave me advise for software.

Killernoy

I´m now set up with the config from the Tool, but the E6 LED is still lit up is this because i have my BLTouch on PWM5?
