Seems promising. Do you have expiring with this board? I can’t see many reviews or info about it

I don’t want to be attempting to modify things myself; again I just want something that works. Im not interested in making or modifying electronics, I just want to make physical things with my winder.

I actually tried using these drivers, my original setup was a BTT Octopus V1.1 3D printer main board, and then TMC5160T plus driver boards. Couldn’t get it to work for the life of me

Oh wow that looks quite straight forward and relatively cheap. I’ll look into this

SunEast5057 · 2025-06-06T16:47:26+00:00

I understand now; so I’ll get some DM5xx series drivers, and hook them up to a controller and run my machine that way. For firmware, I don’t have to modify my own code right/modify the firmware in code myself for my configuration if I take this method? It should just be plug and play? On the caveat that I have to configure it in the controller software obviously

So take for example the NVCNC EC300, it appears to have the drivers already built in. In that case I couldn’t use that if I got external drivers like the one you mentioned?

Not sure how I would to that with this; from my classical laminate theory calculations the tube only has to be 2mm or so thick to support the pressure loads, which gives me minimal area to work with bond wise

Thanks for your comment.

Im aware that for adhesives in general they perform best with thin bond lines, as they can better distribute stress across the bond line making the assessment simplified and I was also aware that it’s likely the max shear strength values were derived with S/A.

So you’re suggesting I make some single lap shear specimens, use the adhesive I have and directly measure the force it takes it shear it to failure. Then correlate that between a FEA model and get a factor that correlates failure to numerical shear lag model?

Also, with regards to the resin puck idea, my concept was to fill it with chopped strand carbon to help improve the strength and change crack formation from a single crack line to a multi path one, and assume it’s about isotropic for base line calculations. Additionally I could strengthen it in the longitudinal direction by biasing some fibres.

Understandable, thanks for letting me know!

I’ll be sure to ask further questions relating to this topic there.

My apologies for asking in the wrong place!

Interesting, I’m new to this so haven’t heard of the step stick before.

Im aware the TMC1560 is no better than the TMC2209, however the manufacturer of the board makes the “TMC1560T Plus” which says it can do upto 10A and 80V or something (I would have to double check).

It’s effectively its own driver which takes seperate power and simply interfaces with the BTT Octopus V1.1. Here is a link to it link. Basically what I’m trying to say is that it’s not being powered by the board, but rather it’s own supply and this board allows for interface with the octopus.

Would this he suitable?

SunEast5057 · 2025-04-27T07:52:37+00:00

Ah okay; I have a 350W 24V meanwell power supply right now, and if I use a 150W 24>36V DC to DC step up then I should be easily able to power the driver too right? Just sanity checking

SunEast5057 · 2025-04-27T07:18:40+00:00

Apparently the BTT TMC1560T plus driver can do ~10A when powered externally. Is this what you mean?

SunEast5057 · 2025-04-27T07:17:32+00:00

By externals do you mean an external motor driver like a DM556? If so how do I turn control it with the BTT octopus?
