Sounds like at least the computer is working. None of the control buttons do anything? I usually (with the power off) check the connector to the control pad and remove and reseat it. Sometimes I have found loose/corroded connections. I usually try and turn the pump by hand if you can get to it somet...

Pictures would help. I have seen a needle puller where you take the needle off and reposition it without removing the face plate. If the back comes off the can be "calibrated" Rarely some have screws to adjust, most have a horseshoe shaped calibration that gets adjusted by squeezing it more narrow o...

That looks pretty great to me. Did you have to draw it in CAD prior to printing?

This is done by moving the lever to the spot where the hol...

I recently purchased a GS2 and have begun a bit of a restoration with a few updates. Here is about where I am currently, parts loosely fitted not assembled. {image} The machine has been in storage for 20 years. It was partially disassembled, with the wiring taken apart and a couple of wires missing ...
