Only seeing 62W out of the advertised 200W of power for v2-50.

For the V2-50 I'm only getting 62W from the wall before the spindle stalls using a power meter at the outlet. This is a far cry from the rated 200W of continuous operation spindle power. Can anyone else verify these findings?

The NSK E3000 series motors have a rated peak performance of 350W of power, and 200W continuous. Pocket NCs documentation states 200W of continuous power. However there is only 1 controller advertised by NSK which doesn't fit the form factor of the Pocket NC. I don't know if a custom part was negotiated or Pocket NC rolled their own controller and just used the NSK motor and spindle. Either way, I'm not reaching any of these ratings.

Warm up itself takes up about 40-45W of power. Perhaps this is a simplification, but I think this would mean that only 20W is used to cut the metal. Even if we got 200W at the wall (this would include axis steppers and electronics), that would be 160W of cutting power, or 8x what I'm currently seeing. Is this logic reasonable, even if simplified?

Hello,

Until recently, the V2-50 machines were shipped with a main circuit board that limited current to the spindle motor. This was done as safety precaution while we did more testing. The most current V2-50 machines do not have that current limit and have more power at the spindle. 

If you are interested in making this modification to your V2-50, please reach out to us at ser...@pocketnc.com and we can provide more details.

Thanks,
