CNC 3040 Parallel port pinout
Hi everyone,
I bought a used 3040T cnc machine with parallel port.
Now my goal is to control it via USB over a Arduino Nano or Duo with GRBL
PC -> Arduino with GRBL -> Control Box
Know anyone the pinout of the parallel port that I can connect X Step, Direction and everything?
The control box is the black one.

Re: CNC 3040 Parallel port pinout
As the various suppliers supply contolboxes with different electronic boards / modules depending on the stepper motors and spindle motor fitted.
more information will be needed to make it possible for others to help
for example
this is one version of a control box for machines with a low power DC spindle motor
found on the net

Attachment 366118

Attachment 366120
printer port
Attachment 366122
you will need the manual for your control box to know the exact function of each pin

I got the control box with the letters "T-D"

Re: CNC 3040 Parallel port pinout
a quick web search for 3040 T-D didn't find your manual
for now you can try the pin out in this manual

Re: CNC 3040 Parallel port pinout
Open the box and check the model of the control box. If it is JP-3163B ver 3.9, here are the pinouts
JP-3163B ver. 3.9
Pin 1: Spindle on/off Relay 1(active low)
Pin 2: X Axis Step (active low)
Pin 3: X Axis Dir (active low)
Pin 4: Y Axis Step (active low)
Pin 5: Y Axis Dir (active low)
Pin 6: Z Axis Step (active low)
Pin 7: Z Axis Dir (active low)
Pin 8: A Axis Step (active low)
Pin 9: A Axis Dir (active low)
Pin 10:Estop (active low)
Pin 11: X Axis Limit Switch (active high) = when NC switch(es) open
Pin 12: Y Axis Limit Switch (active high)
Pin 13: Z Axis Limit Switch (active high)
Pin 14: Buffer Chips “Enable” controlled by computer if Jumper 3 is set to 1-2 position
Pin 15: Probe (active low)
Pin 16: Is supposed to turn Relay 2 on/off but is currently not connected in board.
Pin 17: PWM 0-10V for VFD Spindle AN1 (if jumper 4 is in default 1-2 position) active low
Pin 18: Gnd
Pin 19: Gnd
Pin 20: Gnd
Pin 21: Gnd
Pin 22: Gnd
Pin 23: Gnd
Pin 24: Gnd
Pin 25: Gnd or NC

Hello, I was wondering if the pin out would be universal for most of the controllers? I was the prt-e750 and connot get the spindle to move through mach3 . In motor outputs under spindle, what should step pin# be set as? as well as Dir pin#.
regards,
Josh

NO it is NOT universal - that's why you must open the lid of the control box and find out the model number of your BOB (breakout board) and get the manual for that board.
Or else buy a famous control board from Gecko.

[QUOTE=JoshG502;2093168]Great, thanks for the reply! I have the bob number but still curious how the pins correlate with the step and dir. which is which. Thanks[/QUOTE
Tell us your BOB part number and I or someone else may have the information for you.
