    • RE: Create thermostatic fan without a pin

      My printer is currently in pieces so I can't test, but I assume the way to do it with the meta commands would be a macro with basically this:

      M409 K"sensors.analog[<sensor number>].lastReading"
      while result >= <shut-off temp>
          M409 K"sensors.analog[<sensor number>].lastReading"
      
      M81 S1
      

      Is this correct? It would busywait (which probably isn't important). Is there a way to use them to actually influence M81 S1? (so rather than having a macro to do a delayed shutdown just be able to put M81 S1 in the console)

    • Create thermostatic fan without a pin

      Is it possible to create a fake thermostatic fan? I have an arduino reporting temperatures to my Maestro and I want to have that arduino control the fan too. Additionally I want to have a thermostatic fan configured on the Maestro to stall the delayed ATX shutoff without taking up a pin. My fallback idea is to use an unused pin that isn't capable of PWM. Are either of these possible?

    • RE: Arduino send data to duet

      @zapta I just want to turn the fan off and on so assuming my relay works with a 3.3v expansion pin that's good, thanks.

      Also, if I could connect 3 more thermistors and another relay that would negate the above question. I have e0temp available but I don't think there's anywhere for the other 3 thermistors or the relay for the fan.

    • Arduino send data to duet

      I'm using an arduino with thermistors attached to control fan speed for one of the fans cooling electronics. There are a couple of things I'd like to do:

      1. report 1-4 temperatures back to the duet that'd be viewable in the extra tab

      2. report if the fan is spinning to stall M81 S1

      I'm using a duet maestro and have a paneldue attached w/ 4 wire cable (it seems like the general advice is to talk to arduino with the paneldue port)

    • RE: Bltouch in alarm mode when V_IN isn't on

      @bearer I guess I worded that poorly. I meant when the bltouch's 5v and servo wires are connected to the board's 5v and z_probe_mod pins, respectively, not that I wired them together.

    • RE: Bltouch in alarm mode when V_IN isn't on

      It seems like this happens when 5v and Z_PROBE_MOD (or the servo pin in the expansion) are connected. I got around it by disconnecting 5v and using 3.3v (on the red v_in line which shouldn't work) instead but the bltouch thinks there's a fault on 5v now so that's not great, but it seems to be working for now.

    • Bltouch in alarm mode when V_IN isn't on

      On my maestro, I connected the ground of my bltouch to the E1 pwm pin, which from the schematic should just switch to ground, so that I could turn it off when not homing (to turn off the bright light). Turning it off and on in the homing files is all working, however moving the grounds from the Z probe header to the E1 header has caused the bltouch to be in alarm mode (blinking red light) when V_IN isn't on (external 5v is on). It blinks with or without the ground on/connected but very faintly with it off. Occasionally turning it off with v_in off doesn't turn off the led immediately but it fades slowly so it seems like there's a cap somewhere I'm not noticing. Is there a better pin for this or should one of the bltouch grounds be connected differently than the other?

    • SD card over SPI not working

      I tried to use the sd card slot on my paneldue with a maestro, however I can't get it to say anything but "Error: Cannot initialise SD card 1: Card is unusable." I tried with both cables and just paneldue sd ribbon (30 cm). I tried a 10cm cable just to test. As far as I tested everything had continuity and the card had power where it should. I've tested a separate, bare spi sd card reader and it has the same effect even with a 10cm cable. SPI is working on the board to some extent as the pt100 daughterboard is working, but I can't get sds to work. I've tried the sd that came with the maestro and a clean fat32 formatted card. I don't see anything about it on the paneldue hookup page or the gcodes list but is there something I need to add to the config for this to work? (RRF 3.0)

    • RE: Z max trigger stop z probe dive

      G1 H1 F240 Z5 does what I want. (besides a feedrate change just a move type change from the generated home configs is all that was needed)
