stepper speed very slow

[irving2008]

I would expect those steppers, even on 24v, to handle 2000 full steps/sec easily, thats 10rps, 600rpm or 1800mm/min with little load...

80mm/min = 26rpm = 0.43rps, 86 full steps/sec

have you told MACH3 you are using 1/8 step?

It does suggest your MACH3 settings are wrong...

Just about to say the same thing....

Take a look at the attached image which are the MACH3 motor tuning settings for my router and let us know what figures you have, don't use these settings as they will be incorrect for your machine.

hi irving
i have the "steps per " in mach set to 533.3
200 X 8 = 1600 divided by the screw pitch which is 3mm = 533.3
maybe i am missing something here

resolution seems good i drew a 300mm diam circle and measured it to exactly 300mm

but the speed is very slow

Are all the axis free? no binding ?

[jonm]

yes john everything seems free without the screws attached light finger pressure will move them

[HiltonSteve]

It is the velocity and acceleration figures that adjust the speed, what are they set to?

hi
i have tried various settings in here
