Yes 2 cooling fans (original Predator) in parallel connected to the FAN-0 connector, fans and the PSU are 24V.
Don't know about PWM frequency of Q24000, I copied the setup from someone on this forum (honestly doesn't know who anymore), maybe he didn't use the original fans.
Deleted M106

Don't delete the whole M106, just the F65535 part.

Try this:
; Fans
M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 C"PartCoolingFan" P0 S0 H-1 B1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"fan1" Q500 ;HOTEND FAN create fan 1 on pin fan1 and set its frequency
M106 C"HotendFAN" P1 H1 T45 ; set fan 1 value. Thermostatic control is turned on

@Phaedrux

It's working now, many thanks for your help

Is it also possible to start the cold-end fan at a nozzle temp of 50 degrees on the fan01 connector?

holco62

I see it now line 4 and 5 is for the hotend fan that triggers on 45 degree, I only have to put the connector on the FAN1 output which is now connected on a always on output

Have a lot to learn about G-code

Still needed some tuning, but a week ago I did not expect to have a working printer already

With a Z axis calibration I sometimes see the number 1000 in red in the status box at sensors Z-probe, but usually it stays at 0 (not in red).
What does that mean?

Phaedrux

It's showing that the probe is triggered. What it shows and how long it shows it will depend on the type of probe.

holco62

@PhaedruxOk, but why don't I see the number 1000 in red every time the probe triggers during a calibration?

Phaedrux

What probe do you have?

holco62

The stock Predator probe with a micro switch

I changed M558 H30 to H35 in the config.g, but that hasn't changed anything, but the calibration is going damn slow now

Phaedrux

Well the switch is only going to show triggered when it's depressed, so in normal use it would be very brief.

M558 H is the dive height.

You should consider posting a new thread with your probing issues as it's not related to your initial problem which was solved.

Ok thanks, I will create a new topic.
