As can be seen, the G540 'A' Coil is connected to the stepper half coil leads 4 and COM24. The Adapter lead wiring need to wire the Unipolar coils to the Bipolar drive as depicted below.

The parts needed for eachВ adapter lead is a Rather than cut the existing DIN plug off the stepper leads, I decided to make an adapter lead between the existing DIN plug on the Stepper motor lead and the DB-9 connector that will plug into the Geckodrive G540. The Taig MPS Controller uses 6 pin DINВ connectors for it's motor wiring.В TheВ stepper motors are wired as below You could also use both ends of the coil and ignore the centreВ tap but as the Geckodrive prefers low inductance motor coils, using the centre tap is the preferred option. The Unipolar motor can be treated as a Bipolar motor by using the centre tap and either one of the coil ends. As can be seen below, the UnipolarВ motors have a centre tap in each of the twoВ coils. TheВ difference between the Taig Unipolar motors (a) and the bipolar motors (b) that the G540 is designed for is shown below. Taig Motor to Geckodrive G540 adaptor Leads This problem is solved by constructing the adapter leads as described below.

I had repaired the Controller a number of times, but when the Geckodrive G540 was released, converting the mill over to the G540 was self-evident as the G540 is a complete 4 axis 10 micostepping drive system.ДЄn impediment to using the G540 with the existing motors is that the Taig uses six wire Unipolar motors with a 6-pin din connector on the end of the lead, whereas the G540 is a bipolar stepper motor driver and needs the stepper leads to have a DB-9 connector on them. A good and robust controller in it's day, but in the end the driver gave out. The Taig CNC mill with the Microproto MicroMill 2000HD controller is a combination that a lot of Taig users started off with.В The Microproto controller is a 1/2 microstep Unipolar stepper motor driver.
