When building our RTR sets a lot of time was spent doing the wiring between the steppermotor drivers and the interface. Each driver had a seperate connection for the steppermotor and also a seperate main power connection (75VDC 48VDC 36VDC). To further standardize the connections we have designed/built this new inteface card that has one central power connection...
With this card the steppermotor system is completely separated from the computer. So no damage to the pc's parallel port can occur. No separate supply is needed on the PC side of the circuit.
The card is really nice for those people who are working with brand new computers. I often use older PCs for which it isn't needed.
The kit is offered assembled and tested ready to run...
This kit allows up to 4 drivers to be easily connected to the parallel port of your PC. It is even possible to use 2.1amp and 4amp drivers on the same interface. Because of the ribbon cables slaving drivers is also possible. Making it possible to connect up to 8 drivers from this single interface. Two relays are included, so spindle and coolant can be turned on & off...
