I am total noob to CNC and got as a hobby for drawing and little wood engraving and laser. I bought an OX CNC from AliExpress with only mechanical parts including 4 stepper motors that have the 57h54h-0504A28 number on them.
I also got TBH6064AH drivers and tried first powering with 48v but the noise was there and also I couldn't tell for sure the pulse and DIR + and - connections. I was afraid that something might have happened to the motor that I tried, so I checked inductance by a meter, and all unused motors read around 60mH on all phases except the tried motor which read 60mH in one phase and only capacitance on the other.
so I connected a 18v PS and tried this only axis, and it moved but I think it was slow.
I googled that motor, but it was only mentioned in AliExpress and without any real specs https://www.aliexpress.com/store/pro...700761094.html
do I ditch these motors, as I mentioned, I am not doing any serious work on the CNC, but of course I need it to be functional.
