Hello,

I'm a new member and i hope someone could help me or point me i the right direction.

I recently bought a used Optimum BF 46 Vario from 2007 fitted with stepper motors from optimum controlled by optimum controller IV.

I use UCCNC together with UC100 motion controller and Fusion 360 for CAD/CAM.

I´ve got the x,y,z axis to work but i don´t know how to connect the spindle to the controller IV and setup with UCCNC or if even is possible.

Is there anyone here with a Optimum mill that uses Controller IV or anyone who got a good guess.

Info on the optimum controller IV:

The Unit has:
1 X parallel ports named port 1 (25pin)
9 pin connection plug for a three axis point of origin
4 X slots for the stepper motor cards (I am using 3)
1 X relay port, potetial free relay output (8 outputs/pins)

Pin assignments for the DB 25 male is
Pin Application Description
1 RELAY Switch output eg (motor on)
2 Direction X axis
3 Cycle X axis
4 Direction Y axis
5 Cycle Y axis
6 Direction Z axis
7 Cycle Z axis
8 4th Axis
9 4th Axis
10 Free
11 References switch Z
12 References switch Y
13 References switch X
14 RELAY Output eg coolant
15 Reference switch 4th axis
16 - 24 Free
25 OV DC, Earthing

The 9 pin connection pins are as follows for the reference switches
1 X1 Machine point of origin port 1 X Axis
2 Y1 Machine point of origin port 1 Y Axis
3 Z1 Machine point of origin port 1 Z Axis
4 ROUND TABLE
5 +12V DC
6 X2 Machine point of origin port 2 X Axis
7 Y2 Machine point of origin port 2 Y Axis
8 Z2 Machine point of origin port 2 Z Axis
9 OV DC


I would like to controll the spindle speed, direction and on/off from within UCCNC.
