6XD I/O >> Issue solved

@droftarts said in 6XD I/O:

They should also all be able to cope with 24V.

That confirms my question, just wanted to be sure and safe

I can't find any optocoupler with that marking.

That's the OUT pins, though, not the IO.out pins, just to be clear! IO.out pins are only 3.3V tolerant, wiring 24V to them will destroy the MCU.

@droftarts

These 3 only?

[droftarts]

@tecno You have the 6x fan outputs as well, 3x 4-pin, 3x 2-pin.

@droftarts

Thanks Ian, appreciated.

@droftarts

io1.in is capable to take 24V ??

[droftarts]

@tecno Yes, but io#.in pins don't switch to GND. They are for reading a voltage input, eg endstop, or digital input, eg communications. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#inputoutput-port-capabilities

OK, will have to sort out my input I/O's and see how they work.

[tecno]

@droftarts

All limits are OPTO's X, Y, Z1 and Z2 + one more that I can not figure out is Lz

Also Emergency switch did go to old driver.

[droftarts]

@tecno They can connect to the IO headers. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Sensors_endstops#h-33v-compatible-optical-endstop
You can use 3.3V or 5V for them. Or do they need 24V too?

Emergency stop can go to any IO input, too. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/IO_E_stop

24V ;(

[droftarts]

24V ;(

That shouldn't matter, as the 6XD IO#.in are 30V-tolerant. Just supply the optos with 24V, signal wire to the IO#.in.

OK, thanks

Lz mystery? Looks like a loadcell? Just behind toolheads.

If you mean the thing the pokes out looking like a button, it could be a microswitch or pressure switch, or tool offset switch, or limit switch in case of problems. Otherwise, I don't really know.

Edit: or is that the red LED cross target?

[droftarts]

@tecno Maybe an inductive probe? ie for creating a mesh of the board if it is warped? This video talks about "automatically correct the offset caused by PCB irregularities". https://youtu.be/eW8JtbPlvKQ?t=29

For wiring, see https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#npn-output-normally-open-inductive-or-capacitive-sensor
But could be NPN or PNP.

@droftarts

OK, will take on that one later on as I see it is not criticall for now to get this machine up and running.

Thanks once again Ian, I really appreciate your kind help.

So back to the machine and start crimping some connectors.
