Nice and shiny but couldn't test it, It did not come with mounting screws.

Avec des TMC UART 256 uSteps, on atteint une finesse dans les mouvements et ce dans le silence le plus total

Bon produit, peu utilisé pour le moment mais fait le job.

Der Motor tut zunächst was er soll, allerdings hat sich der von mir erhoffte Effekt nicht eingestellt. Ich wollte damit die VFA minimieren. Also die feinen vertikalen Linien, welche zum Großteil durch Motorvibration ausgelöst werden.Hier bestand, zumindest bei mir kein Unterschied zu 1.8° Motoren.

Used to replace an unknown 1.8deg stepper for a 3D printer extruder. Lots of torque with less current than the previous stepper.Unfortunately it's super noisy with TMC 2100 (known for being silent) drivers and 24v supply. This is likely due to their very high inductance for a NEMA17 motor.Also due to the high inductance these motors will likely not run very fast with typical voltage (up to 24v) for motors this size. Would probably work great in a higher voltage system (36+v) though, and be quieter as well.

Great 0.9 degree stepper but the cable length way too shot. I have a small form factor 3D Printer 165x165x150mm and the length of cables were too short. I had to add a junction so that the cable could reach the board which might have been part of the design of the stepper considering the cable are integrated. Considering the price I would have expected more cable length making one full run possible on all 3D Printers. Other then the cable length it does come with awesome instructions and specs which seems to be rare.

I bought this for my prusa mk3 to cure my VFA but it didn't solve the problem so I swapped the board to an SKR v2.0 mini. This stepper is still really noisy when holding or moving, I replaced this motor with a LDO-42STH40-1684MAC AKA LDO-42STH38-1684MAC from printed solid and it's dead quiet, smooth and accurate even without stealth mode enabled.

Motore consegnato nei tempi indicati. All'arrivo collegato subito al mio dispositivo, funziona benissimo, sono molto contento ed il fatto di essere un motore a 400 steps, non ha fatto altro che migliorare il funzionamento del mio rogetto.

Used to replace the Zaxis motor on a 2418 CNC where I needed more precision without relying on stepper microsteps. Had adequate torque, even though drawing lower current than the original 200 steps per rev motor. It was great to prgram the GRBL to expect "1600steps/mm" (physically 200) :)

Upgraded a laser engraver from a 1,8 deg to a 0.9 deg for better accuracy. work fine with my K40 mother board.

These are some great precision steppers. I use them for a custom dobsonian tracking system and they exceed expectations. The only time I have encountered any issues, it was the fault of the stepper drivers. I'll be using these for all of my precision builds.
