I am not sure whether this forum is right place or not.

Couple of days ago, I got KT-2525 I ordered from K2.
I assembled and connected with my controller.

I setup all axes and tried to move step motors.

All 3 motors looked fine, but the issue happened when I tried to drive motor high frequency.
When I tried to dirve motors around 3000Hz or more the motors just made "Why~~~ng" noise and not actually moved.
but low freequence around 500Hz it worked.

500Hz / 200 step / 10 tpi * 60 sec = 15 ipm. Is this normal or what?

I am using HobbyCNC controller configured 24V drive with upto 15A.
My computer is about 133MHz pentium CPU.
Step motors are purchased from HobbyCNC 200 oz motors.

Lower your acceleration and your velocity, (in motor tuning menu) till you can get the motor to run at their top speed with-out missing pulses. Also check to see what your holding voltage on the hobbyCNC board is set to.

Which software are you using to drive the Hobby CNC board?

Aside from checking the accell/decell, make sure your screws can rotate freely across the full travels of the axis. If the screw isn't prefectly aligned with the axis, binding is assured.

Thank you for your reply. I am using TurboCNC software. Before the motors are installed they worked OK with around 6000Hz. But when they are equiped into CNC, the issue happened. I cannot say the screw rotates "Freely" but feels "tight".
