I have had my 2525 machine from k2cnc for 2+years and have had realitively good results with it. However it has always been hit and miss trying to get ahold of the guys at K2. a month ago my wires were in a bind and they pulled themselves out of the controll box. I emailed K2 and have yet to get a response from them. I hope someone out there can help. anyway, I have the problem narrowed down to the driver. when the machine is on my X axis automatically goes all the way to the end of the table. I replaced the wires but the driver is still acting up. The controller looks fine but it doesn't work.. I have also switched the wires with my other axis and each has the same result the motor runs nonstop until reaching the limits of the axis. Please help. Jerikol

Sounds like the encoders wires are broken or not connected.

I agree with Ger.
It is most likely that the servo motor encoder wire(s) on the X axis are broken.
(The servo is moving the axis, but there is not any encoder pulse feedback to the X drive indicating that the motor is turning, so the drive continues to send voltage to the servo until the machine hits the end of travel.)

Thanks, I sure hope its something simple like that. I replaced the wires from the motor to the control box....maybe the plastic clips are bad? Oh well I will re-investigate..Thank You so much.

Replacing the wires is a good idea. When they were in a bind they could have stretched enough to break the conductors but still leave the insulation/ sheathing/ shielding intact.

The encoder also requires voltage (usually 5 volts DC) so one needs to verify that there is voltage to the encoder.
If you still cannot figure out the problem, post the information that is listed on the label on the encoder such as model, type, manufacturer, etc. Also, any info drawing, etc. that you received with the machine.
