Let customers speak for us
from 44 reviewsGreat motor, easy to wire to the ouro
Couldnt be better! Easy to setup for a tmc 4671 overall, and support is great
Great service!
Great board, and putting it to use in a new AFC solution.
It is the second one and both are working great very good and hot swap safe by the look of it since I was swapping out cables a lot
Very well packaged. I haven't built it yet, but all of the parts look great. Everything is clearly labeled.
I installed this on my new 6 toolhead Stealthchanger build, and it was by far the easiest CAN setup I've used yet. I wired the toolheads using the Igus Chainflex cable, so using both input and output pairs going to each toolhead, and all the toolheads worked without issue. I also hooked up filament sensors for all the ptfe inputs, and was so easy with provided inputs on the board.
Much easier to mount/use than other nozzle-mounted accelerometers. Troubleshooting/calibration now is much more convenient
Great product. Excellent support and customer service
This is my second kit not built yet but should be good when I do
I fried the one that came in the kitchen. This one is working good after it was flashed.
Shipped fast and worked as intended
Works great once you figure it out.
