This tab is under Config on main Mach page
Set up the port as shown, you only need to use Port #1
If The port address is different on you PC USE THAT HERE.
Do NOT go messing with your PC.
To find your port settings go to:
Control panel > System
System Properties > Hardware > Device Manager
Also - Make sure you're using ECP, set in your BIOS
Config > Motor Outputs
Make sure Port is set to 1 for all active axis.
These pin numbers are standard for most CNC software.
Dir LowActive will change the direction
Config > Homing / Limits
This changes the direction the motor travels.
This is standard for most motor driver boards & motors.
You can also wire the motor backwards.
If this is backwards, then the motor is wired backwards.
You can also CHANGE DIRECTION with MOTOR OUTPUTS by changing Dir Active Low / Hi
Config > Ports & Pins > Input Signals
E - Stop must be a hardware switch or Emulated.
If not you will not be able to turn the big red Reset switch at the bottom of the main screen off.
Then NOTHING will move!
Config > General Config
Ignore Tool Change NO! If you aren't paying attention it will ruin your project.
Say you're supposed to change from .125 to .0300, guess what happens - @$#^*&!!!
Screen Control Will expand your screen & make it full size.
G04 This a drill dwell (pause) If not set to ms, it will take SECONDS instead of Milliseconds.
So G1Z-0.1960F4.0 G4 P500 will be 1/2 second in ms.
IMPORTANT Config> Save Settings
Now restart Mach & make sure they saved
Config > Motor Tuning
I use 3/8-12 TPI Leadscrew
Z axis 5/16-18
1.8° Motor 200 steps per revolution x 18 turns per inch (5/16"-18 rods) = 3,600 full step or 7,200 1/2 step, etc.
1.8° Motor 200 steps per revolution x 12 turns per inch (3/8"-12 rods) = 2400 full step or 4800 1/2 step, etc.
FULL STEP IS NOT ADVISED
From Mach3 site -
You must use a Desktop PC with Mach3 Parallel Port Driver
Config > System Hotkeys
This is how you can change the direction of travel according to the arrow keys.
This is how mine is setup.
Home Neg affects how the DRO's act.
Whether they go positive or negative as you move away from zero
FULL = 2400
1/2 = 4800
1/4 = 9600
1/8 = 19200
FULL = 3600
1/2 = 7200
1/4 = 14400
1/8 = 28800
Step Pulse = 10uS
This can be dereased as low as 3 as long as it doesn't miss steps
Setting any axis step / Dir
pulse will set all
Try Velocity at 36 to start, increase as desided until stall
Mach3 doesn't do bluumax router support.

24VDC Power Supply Wiring
for 110VAC ONLY
Black is (L) Line, also hot
White is Neutral (N)
Green wire is Frame Ground (FG) or just ground
(literally Earth ground)
FG and V- are not the same.
V- is DC ground
Black or White wire to wide blade
White = wide
Black = narrow
Sorry for the obnoxious bouncing text but it became necessary.
