one for each external stepper. a new power supply might be cheaper 🙂

Yes, I agree, I'll keep this option as a backup plan.

I'd like to know more about the board mentioned by @Phaedrux, if it's going to be released and purchasable in the next 2/3 months I'll wait for sure.

@T3P3Tony might have a better idea on availability.

In my opionion, the best option would be to configure you e-stop button as a trigger.
https://duet3d.dozuki.com/Wiki/Connecting_an_Emergency_Stop#Section_Making_a_button_do_what_you_want

You could use M581 to configure an external trigger binded to a trigger#.g macro. The macro would be triggered by your e-stop and run the piece of gcode, in wich you may put a pause/stop command and a M18 to turn off each motor so they will move freely.
I'm not sure, but I think with M18 the firmware simply sets the enable pin to the stepper drivers as low, so only the power between drivers and motors is cut.
If you are ok with it you only need to wire the endstop to a IO pin or to a not used endstop pin.

It has only two extruders, trying to keep boards and wiring to a minimum, more parts=more things to break. @Phaedrux

@Peletor That's a possibility. Basically any stepper movement that doesn't directly translate into vertical movement. Mechanical mushiness.

@jaymcd0626 said in Is there a way to fix a blown fan0 output - Duet 2 Maestro V1.0:

Where would I even get a replacement?

From the link:

If you short out a PWM fan, the fan driver mosfet will burn out. The original part number on most Duets is PMV40UN2 or PMV40UN2R which is available from the usual electronic component distributors such as Farnell/Newark/element14, Digikey, Mouser and RS. You can also use type PMV20XNER or AO3400A or AOSS32334C which have a higher peak current rating and are fitted as standard in recent production Duets.

Maybe stick to RRF 3.1.1. Setting up a new build with a beta firmware isn't the best way to go about it.

The heater tuning algorithm has changed in 3.2.

https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control

I'm glad it seems to be solved. Please upgrade to 3.2beta 4, which fixes issues in 3.2beta 3.2.

@bearer said in 5v LED light is red....?:

@Phaedrux are there maestro/duet 3 specific versions of https://duet3d.dozuki.com/Wiki/Hardware_Overview#Section_LED_indications ?

No, but there probably should be. I'll look into that.

@mrehorstdmd said in safety relay for ssr heated bed.:

How are you going to protect the protection relay from some crud preventing its armature from moving, or from the contacts welding shut?

My relay is noisy so I hear it clicking on each time I turn the printer on. Kind of a self test.

"perfect is the enemy of good" . 😉

It not a perfect solution but it reduces the risk of fire due to a short in the duet's mosfet or the SSR.

@dc42 Perfect, thank you

This is weird, during the print never happens that "all motors" are sitting still and this is duet2 board so TMC2660 .... this does not follow our observations but since I'm sure dc knows what he's talking about 😄 the obvious solution is that our observation is faulty that lead to the wrong conclusion(s).

What I'd guess now is that our "live" current is too low.

It worked. New fuse of 7.5A made it work again. Takes a few minutes after setting up to provide enough current to hotend

Huh. I reflashed tehj firmware and it seems to be working now. Strange

OK thx for the information I place an order for normal motor

Best regard

@bearer just a visual artifact

@dc42 I'll keep an eye on it and try my best not to definitely fry my board this time

Really happy with how you design this board. It has been a blast playing with them.

Kudos to you and the Duet team!

@dc42 said in Mini IR Sensor Intermittently Triggering Too Far From the Bed:

When did you purchase the IR sensors? There was a firmware change some time ago to eliminate the false triggering that sometimes occurred with some bed surfaces.

Does the false triggering correlate with a low sun visible through the window, with no clouds in front of it?

All my IR sensors are either purchased direct from the Duet website or E3D, purchased my last batch about a year ago (they are all SMD mounted components) and they came from E3D

My printers are in my workshop it has no windows. Only diffused artificial light.

you have to test it. the idea is to increase the force with which the nozzle hits the bed.

@deckingman said in Max current of vfused for duet 3:

@kvi94 Well to be pedantic, the current from vfused is determined by the size of the fuse. 🙂 But that's not really what you want to know is it? The answer to your question depends on which connector you use. e.g. Out0 is generally for a bed heater and will take around 15A. Out1to3 are the larger 2 pin JST VH connectors and each of those can take 6A. The smaller 2 pin KK connectors can take around 2.5 Amps each. Specs for the gen 3 main board are here https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview

Thanks for the info, it is partly what I was looking for.

Sorry for not being explicit about the particular vfused connector. I was actually referring to the vfused(2 pin KK connectors) which is meant for an always on fan.

If its rated 2.5 Amps, then that should be more than enough for 2 fans and an LED. Correct me if I am wrong.

Thank you.

hi,
back to be relevant again,
this board(1XD) is used for controlling steppers drivers/
what should i do if i need to control ac servo driver?
model and imformation- https://www3.panasonic.biz/ac/ae/motor/fa-motor/ac-servo/a6/index.jsp

appriciate your help
