    Default cnc controller PRT_E1500W

    Hej everybody

    I'm new here hope sombody can help me.
    my controller look like pic. It seems to Work, but !!!!!!!
    I have no errors so i don't know whats wrong.
    You can se on the pic. that X-Y-Z are green when pc is off and yellow when it's on.

    motor output: X: step,2 Dir,3 Y: 4, 5 Z: 6, 7
    Output signal: Output#1, Port #1 Pin #1
    Port address 0x2028 Thats the address parallel port use

    what printer port do you have with the Port address 0x2028
    0x378 is the more usual address for the built in printer port found on PC mother boards

    also I think you will find PRT_E1500W is the spindle controller

    Hej john-100

    Thank you for answering

    I wrote PRT_E1500 because it is the only one written on the controller.
    The port address is 0x378 now i am using another pc.
    Everything seems to work until I put the parallel cable in

    Still the same, PRT: red stop light and when i turn it from manualle to pc display say 400.0
    Inside; X=yellow Y=green Z=yellow A=red ( A=4 axis )

    the photos in your 1st post don't show enough detail so for now I am going to guess
    the breakout board is TX14175
    and the stepper motor drivers are TX14207

    if thats correct
    with out the printer cable being connected
    the breakout board inputs will be pulled high by 12 resistors on the PCB

    on the stepper drivers
    you will find the GREEN pulse / step LED will be on - its near the connection to the breakout board
    and the GREEN direction LED will be on - its near the pin 20 of the 20 pin control IC


    with the printer cable connected
    the GREEN direction LED will go off when the break out boards direction pin is pulled low under the PC control

    when the step / pulse pin goes low the YELLOW LED (or RED on some boards) near connector to the breakout board will light

    if the enable input is used then the RED enable LED next to pin 12 enable will light when the drive has been disabled

    a photo showing the details of a stepper driver will help

    Hej John
    Thanks for the answer
    I've solwed the problem.
    reinstalled Mach3 and found that there was missing a ground wire, so stepper motors are running now
    but I can't find out the pin settings for the spindle. I now it's working in manually with out parallel cabel maybe you can help me

    You are right about the stepper motor drivers TX14207
    but I can't se the model of the breakout board, I'm sure your right there too.

    back in March I tested somebody's TX14175 breakout board

    cnc controller PRT_E1500W-tx14175-bob-jpg

    I traced part of the circuit to find out which pin does what and work out how to test the board

    cnc controller PRT_E1500W-partial-tx14175-circuit-jpg

    to set the spindle speed
    printer port pin 1 provides the PWM signal thats converted to the analogue DC control voltage to the spindle control boards AVI input

    to switch the spindle drive on
    printer port pin 17 controls the relay that is connected to COM & FWD on the spindle control board

    Okay got the spindel to work but can't control rpm ???
    On prt it say's 400,0 i think the spindel run at ful speed all time

    Thanks John-100 for the pic. That help a lot.

    Everything runs but I can't get Mach3 to control the RPM. It runs 24000 rpm no matter what I do
    I found a manual for VFD in English.
    I checked:
    d022 = 0(External acc.)
    d031 = 1(AVI) terminal(0-10V/0-5V) !!!
    d032 = 1(External terminal)
    AVI measure ~10V constant ????

    What have I overlooked ???

    2th Don't I ned a input port setup for Mach3 to show RPM. ???

    It's a pity I didn't trace the circuit for the PWM to 10V DC circuit
    but it looked like its DC coupled and can give you the full 10V out with pin 1 held low
    ( PWM to analogue DV converters with the pulses AC coupled or using a PIC chip can guard against this )

    I suspect mach3 is not sending the pulses to circuit and possibly the active high / low setting is wrong

    the output could be at 10V if in mach 3 the PWM pulse from pin 1 is set to active low and no pulses are being sent

    try changing the active high / low setting to see if the analogue output changes
    the output should be zero when set one way and 10V the other way

    John
