I found the single 5V pwm output limiting, plus to get the most precise control, an analog 5v fed to the CPAP blower driver board is most accurate. Tried a few ways to do that and settled on this board https://www.amazon.com/dp/B079BH3SHX?psc=1&ref=ppx_yo2ov_dt_b_product_details -- it's powered by 24v, will take the pwm output of a regular fan output and create a clean 0-5v analog output. If you run it at 100-200hz you can get the low end to be around .5v, and that's as slow as the CPAP blower can go. I can go the full spectrum and have perfect output control. Not sure of another source for these boards, but I will use them for duet and for klipper configs since they're simple and the best part is the fan control is super accurate.

@jens55 Thanks for confirming!

I edited the pre release into an actual final release of rfm 1.2.0. No need for you to switch out anything it's the exact same binaries.

Will update the tool thread tomorrow. Happy this was solved so easy and sorry for the bug.

@e4d If you mounted the electronics in a metal box, can you confirm that the enclosure is properly grounded (GND)? You can stop DCS on the RockPi and check via gpiotools (gpioread AFAIR) if the input signal is correctly read once you hook up that line to GND and +3.3V respectively.

@dc42 final update for this: your suggestion works like a charm, thanks a lot! 😃

@Phaedrux thanks, I will give that a try once the printer is done with the current job (15 hrs)

I think the limit varies depending on the other variables, but I'm not certain. It's time in seconds though, so you may be able to measure a reasonable ballpark.

@fcwilt No, sorry... Some basic things such as batch programs or conditional gcode is okay, but everything else is over my head - otherwise I would have already tried to compile my own version or add a parameter to G30 in Github...

Thus, I think that would require much more than I can do. Apart from that, I have to admit I don't really like having to switch between two displays.

@SupraGuy Does the fan voltage jumper match the voltage of the fan itself? Other than that, some fans just don't play nicely with pwm, have you tried a different PWM value? I've found that sometimes a really low value like 10Hz can work.

@jens55 Thanks for letting me know. It was just a wild guess, but given that your configuration looked fine, it had to be something like that.

@jens55 for homez, you need to move to a location that takes into account the probe offsets. so if you want to probe the centre of the bed, you would move to the centre, minus the offset. e.g.

G1 X{(move.axes[0].min + move.axes[0].max)/2 - sensors.probes[0].offsets[0]} Y{(move.axes[1].min + move.axes[1].max)/2 - sensors.probes[0].offsets[1]} F3600

For G29, you need to take into account the offset when setting the mesh limits. e.g. if your probe is on the right of your nozzle by 20mm, to start probing a mesh anywhere to the left of X20, the nozzle would have to be at X0 or less. Its not the end of the world if you do get this wrong because as long as your axis limits are correct as RRF will just tell you that your probe points are unreachable and skip them.

@Phaedrux

thanks to all

Yup, confirmed!

As I replied to your other thread, the pin names can be found here: https://docs.duet3d.com/en/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#pin-names

@msugar said in Calling Separate Trigger Files:

What are the appropriate names of these pins?

https://docs.duet3d.com/en/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#pin-names

M950 is used to define the pin that M42 would control.

@chrishamm, thank you, that will help tracking things down. That certainly explains why the original CF card had the warning.

@dc42 OK great thanks! I must have made an error, I'll try again.

@Phaedrux :

3.4.6 same as 3.4.4

but in 3.4.0beta3 print paused message appears first then it's overridden by 'Too little movement' pop up message.

and how i print that messages on console? any suggestions on it?
