Hey Chris,

Onefinity makes nearly no statements about the [capabilities of their machine](https://forum.onefinitycnc.com/t/what-materials-can-a-onefinity-cnc-cut/10255) in the meaning of providing numbers.

In any case I would assume that on a machine that uses a .75 kW [hand trim router](https://www.makitatools.com/products/details/RT0701C) as milling motor (which since it is a [commutated series-wound motor](https://en.wikipedia.org/wiki/Universal_motor) with [carbon-brush commutators](https://en.wikipedia.org/wiki/Commutator_(electric)) which by translating AC into a DC-like motion, induce counter-currents due to [electromagnetic induction](https://en.wikipedia.org/wiki/Electromagnetic_induction) everytime when alternating current direction, that besides the production of heat and sparks, ensures a poor efficiency, furthermore a motor with very [unfavorable motor characteristics](https://forum.onefinitycnc.com/t/incorrect-or-missing-data-on-cheap-chinese-vfds-and-spindles/18909/27), and a power statement that means **power consumption** and not, as IEC 60034-1 requires, the **mechanical power available [at the shaft](https://forum.onefinitycnc.com/t/anyone-using-huanyang-gt-series-vfd/13083/12)**, does not at all translate to the performance of a .75 kW [spindle](https://en.wikipedia.org/wiki/Induction_motor)), the router is the limiting factor, whereas with a 2.2 kW spindle it should be the machine (assuming that a chip load that bends the machine or makes it chatter is outside the range of being specified).
