stepper speed very slow

[John S]

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?

[jonm]

hi
i have tried various settings in here

[John S]

Right the maximum you can do with this is 177.18mm / min if it can get up to speed in time hence your 88mm/min or suchlike.

Leave the steps alone and increase the velocity to 2,000 to start and acceleration to about 150 as a start point.

.

thanks john
so my steps are set right , will try the settings you suggest, i knew i should be able to get a bit more speed somehow, if i can even get to 1000mm a min i will be happy

[jonm]

managed to get my speed up , wired the steppers bipolar single coil
at 2.5 amps the 3nm motors are down to about 2nm but the speed has increased quite considerably can get about over 1000mm/min

If you increase speed, then the torque will inevitably go down.

What was the problem?

(Glad you got it sorted!)
