@droftarts said in Is this board Genuine or Clone?!:

Duex5 looks similar to my genuine one, except for the heatsinks on the stepper drivers. Do these actually make any difference to? I thought the stepper drivers conducted very little heat through their plastic tops, mostly through their bases into the PCB, and had read that you get better cooling by mounting the heatsinks on the other side of the PCB!

Ian

Precisely so! The stepper drivers have a large metal pad on the bottom to conduct heat away through the PCB. That's also why there are all those small holes underneath each stepper driver - they're called "thermal vias" and serve to increase the surface area of the connection between the chip's power dissipation pad and the copper of the PCB.

Putting heat sinks on top of the drivers is quite pointless if the PCB is correctly designed (which it is in the Duet3D hardware).

Putting them on the bottom might help with the tiny little plug in stepper driver boards used on other hardware, but compared to the size of the PCB on the Duet/Duex boards, I wouldn't imagine they would make any significant difference.

hi thankyou i will do

@T3P3Tony Unfortunately, you're correct. The M3D version only comes with the board and a cord. Their service isn't the best and personally, I wouldn't recommend them.

@boldnuts all. if you have an issue please email info@duet3d.com

@bearer It could have been a bit longer but I tested for continuity between each leg and the pads on the front and back the best I could. I'm going to try and hunt down a spare wifi module just in case 👍

@nitrofreak, this is from one of C.R.T's Duet videos. He criticizes behaviors, not race. We should be more careful with public accusations. 😉

Sorry, I have overlooked that completely.
Thank you.

@dc42 That was easy, ty man and ty for your hard work.

it's 3mm diameter x 15mm long, to fit a modern E3D heater block.

@elmoret Thank you very much for the offer. I had already seen you and Filastruder help another customer in a bad situation with M3D and was already convinced you guys go above and beyond to help out our community. Hopefully M3D does the right thing and finally sends the promised replacement board but in any case i'm a Filastruder customer from here on out. You folks are awesome thank you!

Why is there no double axis option?
An expensive hardware is the duet3d and such a cumbersome setting I don't understand is not everyone with programming skills I could simplify setting here ...

@dc42
I have posted the picture in my other thread.

I suggest you email info at duet3d dot com.

@gisli said in Moving mass / torque requirements:

@deckingman Ian, your setup is very interesting, I have never seen counterweights used in this way,

Forget the counter weight / dynamic load balancing thing - it makes no difference (although it might if the frame flexed rather than the entire printer "rocking"). The point was that you can print at 300mm/sec (if your hot end can melt filament that fast) with a mass of 1.5kgs using Nema 17s.

I don't know of any long, thin, nozzles that would accomplish what you want to do.

6mm belts will be fine - it's what I use. Timing belts are designed not to stretch (although some cheap Chinese ones might).

I approve the exchange of that board under warranty. But please check the wiring to that motor for possible shorts or intermittent connections.

Duet 3D shows a link for dc42's company Escher Consulting Ltd, trading as Escher 3D which in turn has a contact us page with an address:

Glad you sorted it out 😄

Happy new Year,

are there any news yet?

I've extracted a bed heater from an old printer to test your board with. I wasn't able to reproduce the problem using just stepper motors and a 5 ohm dummy load. I hope to test this and post the board back to you on Monday.

Please confirm the address to post it back to by PM.

We (Filastruder) have a solution for this, feel free to get in touch via the contact page on the Filastruder website for more info.
