@droftarts I can send the Pin Down and Up and I will test everything else tomorrow but I think if that works now it should be fine. I will give an update on the other stuff tomorrow when I´m back at the printer. Thanks!

@Phaedrux and @caviara
it s ok now , i gone try IR sensor
thanks a lot

@tazla said in endstop:

@tazla if i would setup 3 relays for endstop switches and just use24v for the them

would that be bad somehow?

i made a 24v circuit to a relay and that worked

@phaedrux It's at 12v....because the LEDs are 12v, but the rest of the system is 24v! Of course!

I'll try fixing this tomorrow but I seem to remember there was some reason I had it wired up this way.

EDIT: I remember, I blew some of the mosfets on the duet over the years so the duet fan headers don't work right, hence I used the deus. I really should fix this things properly someday

@ukwebb said in Failed driver on Duet3 Mini5+ ??:

This happens even when i replace the motor and wire with a known good one
and also putting the existing extruder motor wire onto a different driver it too works well
so i can therefore only conclude that the stepper driver itself has failed.

It would seem so.

@user3d
I've made fan shrouds from color-changing PLA, just to see if there is any difference in fan-direction.
The color changes from orange to yellow above 33°C

I could see changes with different filament temps, but not related to fan direction.

Note, the solution for correct run of relay is:
M950 F4 C"exp.heater7" Q500 (create a fan4)
M4106 P4 S1 (to turn ON the fan or relay).

@mgjosh A7X is the new one i had bought. 9CR is the one ive been using for a long time and suspected was going faulty. 9CR is the only one that works with my current config. That you for your reply.

@rasa

AFAIK there are no pinouts for stepper signals on the duet3 6HC. The most elegant solution is indeed what @Phaedrux and @Dougal1957 have suggested. The Duet 3 Expansion 1XD board provides all the pins you need for connecting external stepper drives and has extra fuses for safety.

@pkos, I'm sorry your Duet appears to be faulty and I approve a warranty replacement. Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@phaedrux

Shhh, don't tell my fans that

It's a ferrite bead with impedance 1K @ 100MHz. But I can't see any way that it would burn out, short of a bare 24V wire or something like that touching it.

@dc42 Thank you

@o_lampe said in rc servo not moving:

@cosmowave

Sservo pins are just GpOut pins with a different default PWM frequency.

Maybe you must not overwrite the Servo frequency with 'Q500'?

I have tried different frequencies, also without a "Q" Value

@cosmowave said in rc servo not moving:

M950 S1 C”exp.heater3” Q500 ; assign GPIO port 1 to heater3 on expansion connector, servo mode M280 P1 S46 ; set (~1deg?) servo position on GPIO port 1 (Servo range 44.2 - 141.2?)

Looks like those are the wrong sort of double quote characters in your M950 command. The correct ones look like " not ”.

O yes! You are right! This is a bit embarassing...
sorry for that, and thanks!

@dc42 Yes, all are running independently now and everything is stable, thankyou.
