MPG (Handwheel) wiring and configuration needed in Mach3 , I have Red 4 axis mach3 board and standard handwheel.

Mach3 Red handwheel 10 socket port:

+5v | o o | GND
X | o o | Y
ACH o o | BCH
Z | o o | A
X100 | o o | X10

Standard MPG with ESTOP Wire Colors:

(Red - Green/black) -- 5v
(Black - White/Black - Orange/Black) -- GND
(Yellow) -- X
(Yellow/Black) -- Y
(Green) -- A CH (Encoder)
(White) -- B Ch (Encoder)
(Brown) -- Z
(Brown/Black) -- A
(Orange) -- X100
(Gray/Black) -- X10
(Blue & Blue/Black) -- IN1 & DCM in BOB

2- Config -- ports & pins -- Input signal:

OEM Trig#1 port -- 3 , pin -- 5
OEM Trig#2 port -- 3 , pin -- 6
OEM Trig#3 port -- 3 , pin -- 7
OEM Trig#4 port -- 3 , pin -- 8
OEM Trig#5 port -- 3 , pin -- 9
OEM Trig#6 port -- 3 , pin -- 10
_____________________________________________________
3- Config -- ports & pins -- Encoder/MPG's:

Encoder1 -- Enabled
MPG#1 -- Enabled
_____________________________________________________
4- Config -- System hotkeys:

Trigger 1 -- oem code 185 To select X axis
Trigger 2 -- oem code 186 To select y axis
Trigger 3 -- oem code 187 To select z axis
Trigger 4 -- oem code 188 To select a axis
Trigger 5 -- oem code 192 To select x10 jog step
Trigger 6 -- oem code 193 To select x100 jog step

5- Config -- General Config... -- Jog Increments in cycle Mode:

Position1 -- 1
Position1 -- 10
Position1 -- 100

6- Program Run Alt1 -- Tab key -- Jog Mode MPG
_____________________________________________________
Notes:

0- Just use 5v pulse generator (encoder) , higher than this will damage your BOB.
1- Plugin control -- RnRMoton "MPG disable" must not selected
2- Check Encoder in Setting Alt6 -- MPG Diagnstic -- MPG1 ,by rotating encoder you can see count and velocity ; just by settings in step 3, you can check encoder test
3- In Program Run Alt1 -- Tab key -- Jog Mode MPG, you can see selected axis and jog step
4- to select axis and jog step you must push side key
5- Default jog step is 1 for encoder without pressing side key , pressing side key equal to selected jog step
6- To calibrate your MPG: Function Cfg's -- Calibration of MPG's
7- Do not forget to save any changes in Config -- save settings..
