Fan with PWM from filter unit how to hook up and address
Excellent advice however I got the PWM part of the fan wrong. It's a 3 wire fan. The third wire is a tacho. It won't control the speed. To be able to switch it on and off is worth a lot. The bed heater port can do that. In the mean time I'm going to search for payable PWM 24V 4028 fans. Thanks for your advice.

Fan with PWM from filter unit how to hook up and address
He is, because the 2 4028 24V fans would draw a too heavy load on the boards fanport and possibly fry by overload the 24V rail of the board. Problem was too have the MOSFET switch on and despite a days and nights long search on Google there's no documentation on CNN connecting the MOSFET to another device than a hotbed. latest info points me to the endstop signal pin being Digital and connecting that to the "SIG" port of this MOSFET which is designed for a digital signal.

Fan with PWM from filter unit how to hook up and address
I read that similar MOSFETS need a 5-24V signal to switch, so maybe that's the thing. I guess it needs a 2 wire setup from signal pin to Bed + and gnd to Bed -. The signal pin coming from a PWM fan port since that generates a 5V signal. If anybody knows please guide me in the right direction.

Fan with PWM from filter unit how to hook up and address
Thx, got it! Now the only thing I've to figure out is the printer.cfg code, especially the pin names. I'll trace back the part cooling setup and pin names and copy the setup with the new pins .

Fan with PWM from filter unit how to hook up and address
Thanks, I waited to connect it for an advise. You saved me from frying my Octopus Pro. Thx! I'll use the MOSFET and signal it from a free port. Can I still use the PWM the same way the 4028 part cooling fan is used? PWM wire connected to a pwm port? Or does the MOSFET limit it to on/off only? As far as I see it the MOSFET is the equivalent of the always on port but only switchable. Thx again!

Which Thermistor to Choose
Got a Beacon Rev H, was a bit of a struggle to find a decent mount but think I got it covered now. So now it's restart, back to config and go for the beacon right?

That's worth a lot, today I calibrated the RR . It is a lot to do.

Thanks, better to be safe than sorry. It's more expensive but it works. I'll go that way too eventually.

Which Thermistor to Choose
So far the functioning of the BTT microprobe was unsuccessful. I have not received the configs from @MDFPereira yet. I tried a solution from @MDFPereira which was posted on Facebook (ran the configurator, installed a generic probe and included the microprobe.cfg ). No joy, I kept receiving the error "z-probe activated after retraction". Tried inverting the sensor pin setting but error stayed. So I swapped back to an old bl-touch and reconfigured the setup, that works fine. Calibrated and PID tuned bed and extruder. Then I ran the belt tensioning macro. Gave me a nice graph but I'm not sure what to look for. In the low frequencies there is noise on the graph but at the higher frequencies there is less noise shown and both belts are almost equal. How to interpretate or read the graph and translate that to my settings. How are frequencies and speed related to each other and when is a belt too tight or too loose? I hope someone can point me in the right direction.

Any beacon? Or is there a significant difference between brands? I do have a proximity sensor laying around ( Finglai LJ18A3-8-Z/BX-5V) which looks awfully similar to the loose probe/beacon on the RR site. I love tinkering and trying once pointed to the right direction.

Mikkl, my compliments for your fantastic work. I just switched to klipper (my CR6SE) but the RATOS layer makes it so much easier and better to understand. I'm now in the process of calibrating it . A bit scary for the calibration of the BTT microprobe. Any suggestions?

same applied for the EBB 42 1.2 toolboard. That one I could reset (boot+reset release reset and boot) since I had it already wired it was a bit of a challenge to reach the buttons but two ballpens solved that 😉 ) Here it would flash but after the flash the same error. Going back and forth worked fine.

At first I chose the DFU method but had not yet placed the boot jumper. I placed the jumper and tried the reset button but nothing happened and the interface kept telling me it couldn't find it. Also hitting the back button and next again with reset press didn't change that. After killing the power and restarting it, I entered the DFU again, it recognised the board and started flashing. After the flash it gave an error. But after going back and next again it walked through
