    Yes they are, and now you ask lol I used the AM882 autotune function on the last motors I just replaced not actually "Autotuned" the new motors so they aren't even close to set up correctly.

    Last motors were only 1.8nm so must be out and I did a cut for 30 mins and the motors were cool to touch, need to tune them in to get best performance but motors are stronger than machine lol.

    I only built the machine out of 4590 heavy duty extrusion it's not steel.
