My custom Cartesian

@obeliks What I am very interested in is the question if these motors will have an audably different noise level and if so in which direction.

OBELIKS

I will measure before and after.

wilriker

@obeliks Cool, thanks! Looking forward to the results of that. Because if they are more silent, guess what's next on my to-do list.

OBELIKS

First thing, package was here in 3 working days and it came from Germany.
Now the big problem (maybe?), the shafts have no flat spot. At all.
Second small problem, the leads are short.

deckingman

@obeliks No flats is no big problem - all you need is a file. The shafts aren't usually hardened so it's easy to do.

OBELIKS

@deckingman Ah, not hardened, OK then. Thanks.
I haven't even tried, I'm just from the vacation. The good thing is that next week I'm still at home.

deckingman

@obeliks Yes it's dead easy to do. I've filed flats on all 10 of my motors.

Yeah, Wantai has a European warehouse in Hamburg here in Germany. So, if you ordered from their "EU Stock" it'll come from there.

OBELIKS

Results are in they are about 5dB quieter and 5°C cooler than stock A8 steppers
Also, it seems I am melting.

wilriker

@obeliks Definitely sounds great! At what settings do you run them?

OBELIKS

Just like on A8 steppers 50%, so 1200mA in case of Wantai.
The loudest ones are Z-axis, but that is related to M5 leadscrew.

Just wanted to say thank you for your build log.

I went a very similar route to you, started with an Anet A8 and am now left with a box full of spare bits that looks suspiciously like an Anet A8 (Only thing left is the stepper motors and guides)...

The Duet was a bit of a pain to configure after using Marlin but the first test benches turned out like a dream with your settings.

So thanks again!

I'm glad that this helped you.

@OBELIKS Can you measure the length of your Anet stock steppers? I just measured the length of the newer 0.9A steppers and they are not 40mm but only 37.3mm long.

So compared to the 48mm long Wantai steppers (would you be so kind to measure their length as well?) that is an extra of over 10mm and I have a feeling that I will not be able to fit them everywhere.

OBELIKS

@wilriker sure, tomorrow. I wrapped up for today.

OBELIKS

Eh, I needed to fetch a beer from the storage. So I hopped in to the "workshop"
Anet steppers are 37,8mm long and Wantai real length is 46,8mm.
And the beer is imperial IPA with 10% alcohol. And it is brilliant.

Thanks for that! Will measure on the weekend of I can fit them. Biggest issue might be Y axis as my heat bed holder has only a certain width cutout for the motor.

I am all but a beer type but happy that you have something you enjoy.

OBELIKS

If it's aluminum bed holder, just chop it.

wilriker

@obeliks It is aluminium. Though, I have some concerns of messing with the statics of it if I chop it. But first I need to find out if it will be an issue after all.

wilriker

OK, I looked into the dxf file that is used to cut the bed holder and it has a clearance of 58mm for the Y motor. 46.8mm motor + 6mm damper leaves 5.2mm for the thickness of the motor holder (which I am not absolutely sure but I think is 3mm) and some clearance to compensate any amount of mounting skew... this will be tight... And as you can see on the image of the seller below there is not much room for removing further material without coming really close to some existing holes
