I am new to this forum and not a native English speaker. I am sorry if I do something incorrect :)

I started studying at a university last fall and discovered that we had a CNC router in the student workshop. Because I don't have access to other machines during the weekend and the afternoon a CNC would come in handy. Because nobody really knew how to operate the machine I started to learn Fusion CAM and Mach3 and basic CNC machining with the help of youtube and forum posts. After solving many in retrospect trivial problems I am now stuck a point where only help from an expert can help.

The major Problem is that the machine is only moving at max 1000m/min and the steppers are still stalling.I tried to change the mach3 motor tuning settings but the only thing that helped was reducing the feedrate. Is 500mm per minute really the maximum feedrate achievable with this hardware? If so this machine is pretty useless for anything else than starting a fire. Because this is exactly what happened when I tried to cut with a 2 flute 6mm bit into pine at the spindle min speed(10 000rpm). My questions are now: Is this machine any good without major investment?
