Help Identifing old stepper controller board

Hi All,

Hopefully someone can help. I have an old CNC, installed I think by Machinetoolcamp back in '06 its running deskcnc with a 2nd gen lmservices control board. However the z axis controller for the step-syn drive popped a cap. I can not find any markings on it to help identify it to replace it.

Does anyone know which controller this is or possible could direct me to a replacement that would be usuable?

Thank you all in advance.

Dennis

Looks a little like a Gecko G250? Maybe an old version?

the faulty component is one of two current sense resistors used to measure the current through the motor coils

Attachment 427320

with the shadow its hard to see if there is a decimal point between the zero and five

its possible a fault with one "H" bridge has overloaded the resistor
