Harrison Lathe and Gecko's

Hi,

This post is aimed at Mariss but anyone else who can answer is free to jump
in.

I have a Harrison 280 CNC/Trainer Lathe with a blown Z amp. The motor is a
four wire stepper and the board connections are motor clock, motor
direction, +85 volts DC @ 10 amps, +24 volts DC, 0 volts and Drive Enable.

The problem is that the drive is blowing the 2 amp fuse on the +24 volts
when the machine is powered up. When the X amp is plugged in nothing blows
so I assume that is ok.

I cannot identify any of the components on the board except the logic even
with the help of the internet and a circuit diagram is out of the question
because I don't know the board manufacturer.

Is it possible to use one of you Gecko stepper drives to replace it with out
pulling the whole machine apart and starting again?

Regards,

Terry
