@jay_s_uk Thank you !!!! Have a lovely weekend!

@jay_s_uk

Awesome, thanks! Dummy question:

It is has to be mounted to ensure, that this part (the red X) where the moving part has to touch it ?
OR
A thin "flag" has to get into the U shape to block ?

And this is the connector which is compatible with the 6HC or it is need to be replaced with ?

@jay_s_uk

Can you recommend an optical endstop if thats more pro pls, which you have experience with and fit well with 6HC ? I will go that way too .

@jay_s_uk
Awesome, thanks for the heads-up!!

May I ask if by any chance you could recommend a reliable end switch for the axis ends which also connect to 6HC well ?

@jay_s_uk

Thanks, so to summarize, the best way to do this is:

• Buy and connect a 3HC expansion board with twisted pair (as I found based on search) cable to 6HC
• Connect 5 axis, 1 extruder stepper motors and its filament sensor to 6HC
• Connect 1 extruder stepper motor and its filament sensor to 3HC

So, at this way, I can fit all steppers, plus their filament sensors on the same board as dc42 indicated it above.

Correct ?

@dc42 Not to hurry you, just to be able to step forward, may I ask your kind help on the 2 questions above? So:

• if all 7 stepper motors (5 axis, 2 extruder) can be connected to 6HC directly ?
• can you recommend any other reliable filament sensor works with 6hc direct (because duet3d cant be purchased anywhere)

BIG BIG thanks in advance, and sorry to take your time.

@dc42

Thank you for the confirmation!!

i have 5 axis stepper motors (x,y, z1, z2, z3) and 2 extruder ones (titan aqua), so in total 7 stepper motors.

I am sure about the 5 to connect with 6hc directly to use the onboard stepper motor drivers, but the additional 2 titan extruder may fit as well without any expansion ?

And in case I cant get the Duet3D magnetic filament monitor as it seems out of stock everywhere, can you recommend any other you trust and can be well connected to 6hc ?

Many many thanks for your time and help!

@Veti

Fair point, however, when you dont want to have many spools with a small bit of filament left, without a sensor, you are unable to use a complete spool 100%, at least in my experience.

@ Veti

Truly ? I see. In my case it can happen e.g. overnight, so I would love to make sure, that he printing paused, while I refill the filament.

Hoping may others can respond, especially on the technical prospective, whether the 2 filament sensor can be attached directly to the Duet 3 6hc, right ? I am asking this, because after reviewing this 2 docwiki source, it still not fully clear:

https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_filament-out_sensors

https://duet3d.dozuki.com/Wiki/Duet3dFilamentMonitor_RotatingMagnetVersion

@Veti

May I ask an other quick question:

I am planning to use 2pcs (since dual head) of Duet3D magnetic filament monitor.

Questions:

1. Did I understood right, that this will work with ALL filament (even PVA or transparent) ?
2. Did I understood right, that BOTh can be attached directly to Duet 3 6HC without the need of any daughterboard or other extension ?
3. Do you truly recommend this? (I am asking this, as its very hard to buy, so would be great to know if this worth it or you recommend something else ?

Many many thanks for your time and help!!

@oliof

Excellent question, but I am afraid, I dont know.

@Veti

Yeah, thats what I was afraid of. Thats life, at least for now

@Phaedrux

Never!! Just try to listen on all of you, whom smarter on this field, than me.

@bearer said in Connect OLED display to stepper motor:

Whats the end goal? The display doesn't really do anything usefull unless coupled with a driver.

As linked to you can buy the board and use with any stepper, but its much much more than just a display.

Just purely for fun, as I had written it. No real function, but as Veti pointed out, since its only for closed loop, I need to drop this.

@Veti

I see, thanks for the heads up! Since you already recommended earlier the standard stepper motor setup against of the closed loop one, I would not sacrifice that just for having the displays. Many thanks!

Hi,

I wonder if any of you have experience/tried to add those 0,96” OLED displays for a standard nema stepper motor ? (In my case: e3d super whooper)

I know it is possible to buy complete servo kit from BIGTREE, but what I am looking for is to add it to a normal stepper motor.

I know it is strange idea, but it looks super awesome , so why not ?

Many thanks for any help/guidance !

@Veti SUPER CLEAR!!!!!!!!!!!!!!!!!!!!!!!!!!

I will add a fuse too, just as suggested in docwiki.

Big thank you !!!!!

(PS: i mark this for solved now, until i have new question. )

@Veti Big thanks, and I did read the SSR article you pointed to me already, I even have the SSR wiring diagram, so allow me to rephrase myself:

Having only a built-in thermistor and a properly applied SSR, is enough for Duet 3 to control on/of and specific celsius temperature, right ?

(So basically all not needed watts will be "burned" at SSR, simple is that if I understand well the concept behind)

@Veti said in Kind help on req Duet3d hardware based on specification:

B3950 Thermistor

As far as I see, it has: NTC 100K thermistor buil-in. This one works also ?

And back to my main question, no additional HRDW needed to control the temperature, so not only read it, but control it as well ?

Hi Again,

I am working hard to put together a final wiring diagram to be confirmed, but I ran into some questions, allow me kindly to ask them.

(I always try to search the forum and the docwiki before I ask, but if I am confused, better to be safe than sorry)

Background:

• The Keenovo heatbed I had chosen has built in thermistor.
• I had chosen a proper SSR.
• I had found the wiring diagram for the Duet 3 6HC + SSR + Heatbed as well as the mainboard wiring digramm as well.

Question:

• If I understood well, Duet 3 6HC use the thermistor value to know the actual temperature of the bed.
• But do I need a separate thermostat attached to Duet 3 to control, or thats will be handled by Duet 3 natively, OR I need a TEMP DAUGHTERBOARD OR .. ?

Many thanks for your time and help!
