Yes I do have a multimeter

Do I test the 3 ribbon conection at the Driver or where the Parallel port end

What am I testing Ohms or volts ?

[john-100]

if the remove the BOB from the control box its possible to use the wires that are now connected to the E-stop switch
to make a temporary connection to a 12 to 24V power supply

see the red 2 pin connectors


as the BOB has a diode to prevent damage due to the reverse connection of the supply

you can power the board and when you get the polarity correct you will have 3 LED's on

one marked 24V that indicates the 10V regulator is working

the second you have the 5V supply to the 74HC245 IC's that buffer the 12 signals from the PC's printer port

the third LED indicates the relay controlled by pin 17 is on

all the BOB's inputs (pins 1 to 9 + 14 , 16 & 17) are pulled up to +5V by 10K resistors

all the 74HC245 outputs should be at +5V

so you should have + 5v on all the 3 pins of the connectors for the 5 axis ribbon cable connectors
Attachment 387218
assuming you put the D-type connector back together you can connect the multimeters negative wire to the HEX stud or the shell

to test the signal path for problem X axis

the 25 pin D-type connector on the BOB will be the mirror image (pins 13 & 25 on the right)


short pin 2 to ground (to the shell may be easier) and the3 pin ribbon cable connectors pin 2 should to down to 0V

short pin 3 to ground (to the shell may be easier) and the3 pin ribbon cable connectors pin 3 should to down to 0V

if you put some sleeving on the pins you not testing it will make it easier to avoid shorting the IC outputs

That`s exactly the same on our units, did you copy/paste the mach3mill XML file that came together on the CD? copy/paste that in mach3 folder then voila!! everything will be factory calibrated in seconds

Hey i bought a 6040 USB but i din't get the software and now nothing works, are you willing to send me that mach3mill XML file please?

Gr Mike

Double sorry

I sure would like to have a copy of that CD or just the Mach3mill.xml.

I'm trying to get a 6040 China Special going and that file may be just what I need. I bought from some random seller on Ebay, and got the bare minimum from him.

Share your cnc and some pictures so we can help you better.

It’s the exact same CNC Motion controler that is being talked about earlier n this thread

ok ShellbackBill, that looks the same as mine, I will attach my Mach3 file for you, let me know what else you need and whats happening, I am also using the UC100 to connect to my PC it looks like you have the usb.
. I can help you set things up have tryed this USB soft ware? https://www.chinacnczone.com/en/soft...er_l282_1.html

Thanks Carl!

I'll be loading that up in my system this weekend. Hopefully it will sing for me.

Looks like different China Vendors do a better job of supplying necessary info with their systems.
