Mach3 / Fusion / DIY CNC ... speed problem

(1/1)

borquee:
Hi,
I have diy cnc with 4000mm/min speed (157in/min) 12nm motors working on Mach3 and Fusion 360

So ... I have a convex surface that I need to machine and maximum speed that I get is 1200mm/minute ...
Fusion says it should be 12min, CNC is working for over 25min

I tried increasing feedrate from Fusion and Mach, tried smoothing from Fusion... it just floats around 1200 whatever parameter I change ... on a flat surface it speeds up
my guess is that there is something with Mach setup

Controller is Pokeys57cnc over ethernet ... so there should be no bottlenecks, Windows machine is ok, Mach is fully licensed.

Try increasing the Acceleration in Motor Tuning for each axis and save the changes - this will improve your overall Constant Velocity speed.
