and I used Normally Closed contact LS (series connection), if you used a Normally Open LS (parallel connection), set this to active low)

X-Drive Limit Switch = pin- 10 (PS-6), active high (I used this since it is not inv.

Z-Drive Enable = pin- 16 (PC-2), active low (I used this since it is not inv.).

Z-Drive Direction = pin- 9 (DP-7), active low.

Z-Drive Step Pulse = pin- 8 (DP-6), active low.

Y-Drive Enable = pin- 7 (DP-5), active low.

Y-Drive Direction = pin- 6 (DP-4), active low.

Y-Drive Step Pulse = pin- 5 (DP-3), active low.

X-Drive Enable = pin- 4 (DP-2), active low.

X-Drive Direction = pin- 3 (DP-1), active low.

X-Drive Step Pulse = pin- 2 (DP-0), active low.

It is more cheaper and easy to get from hardware store (like : ace hardware or home depot/depo bangunan).Ĭontroller bits setup ( LPT I/O port bits) with selected bit function (based on KCAM drawing example) :

For the mechanical driving, I will use ball bearing slide drawers rather than using linier rails with roller bearing. I prefer the second choice because it is more challenge, besides that I already bought those stuff. So I think I must search for the new ones with the same spec and abandon all what I have or make my own controller for this stepper motor. I put email in the stepper motor discussion news group, but don't have any replay or answers. Up to it is NEMA-34 (3.4' dimension) can drive about 2 metres x 1 metre or below. It can drive CNC table with size about 1 metre x 0.5 metre or below. Nema-23 standard (2.3' dimension) has more torque to drive. The torque is very small, only can drive small load. Disk drive stepper has NEMA-17 standard (it is about 1.7' dimension).

Searching the net, but I could not found any related with this kind of stepper. At first I think, I could found the schematic controller from the net. I found used stepper motor NEMA-23 standard, but the spec for 5-phase coils, not quiet the same with the other making, like 2 phase bipolar or 2 phase unipolar (the spec like stepper disk drive). It will drive slower, but I think it's ok for the begining. I bought 3 of them each with 1 metre length each of has pitch like 6mm (1/4') with thread about 26 tpi (turn per inch), 8mm with thread about 20 tpi and 10mm (3/8') with thread about 17 tpi. I found cheaper threatrods, but the threads very few. An exception of another parts will be build by myself. First, I search for the important materials, ie: stepper motor drive, threatrods, and mechanic driving.
