Keeping the speed fixed, I varied the power this morning and got this set of results.





32A



35A



40A



The 32A cut is terrible, there is severe bevelling on the X axis cuts but oddly not on the Y axis cuts, no idea what's at play there?


I think the 35A cut is best, the dross knocked off pretty easy and it's on size.


The 40A cut is not much different than the 35 one so best speed is likely 35-37A?


Overall, I'm not impressed and am slowly losing faith. it seems this machine needs way more power than it should and does not give results to match, yet.


Do any of these cuts look respectable?
