  1. Re: Cold weather affecting proximity sensors?

    yes the cold could effect the sensors

    what is the sensors part number ?

    If its from Honeywell or Allegro Micro Electronics you may be able to get a detailed data sheet
    to know how changes...

  3. Re: Incoming power voltage to my Haas causing power on issues

    I don't have a Haas so I don't have a schematic or any details of the electronics used

    but notice the 2 days it failed the outside temperature was below 20 F

    32F or 0C is freezing !!

  4. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    have you connected one axis to the BOB or all three?


    the 6th photo in post 3 shows a 3 pin connector on your stepper driver

    so you just step direction and common - not sure if its 0V or...
  5. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    Yes
    That BOB will be easier with the screw terminals to connect to
    431332

    I would still use the larger 1XHCEL Board relay to keep the mains away from the BOB !!!!

    Re: 5v proximity sensors

    What breakout board or motion control do you want to connect the 5v proximity sensors to ?

    why do you think you need a optocoupler ?

  8. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    if your not using the 4th axis

    this is one possible way of using the "clock" signal from the printer port pin 2 assuming the BOB schematic is correct

    looking at the schematic...
  9. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    I have found this data sheet for the relay board

    431258

    and a schematic for the BOB that needs checking

    431260


    I have a couple of questions
  10. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    After looking through your photos

    If the HN25-150-24 powers your stepper drivers , I would use the 24V version of the relay board so the stepper driver power supply can power the relay coil

  11. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    this is the first relay I found that may enable your BOB to switch the mains supply to your spindle

    that's good to know the G540 is working

    do you have a multimeter ?


    Assuming you have

    Re: BREAK OUT BOARD HELP

    Hi robwiacek

    how did you know how to wire the unipolar motors to the bipolar stepper motor drivers ?

    did you have a data sheet for the motor to know which 3 wires goes to each coil ?

    Re: BREAK OUT BOARD HELP

    Just looking at your photo of the BOB I can not read all the labels but

    I can make out you have the 12 outputs ( pins 1 to 9 + pin 14 + pins 16 & 17 )

    the question is how many axis do...

    Re: Proximity Sensors Gecko G540 and Mach3

    yes thats correct

    its the easiest way to narrow down the problem

    to see if its the G540
    or
    the Proximity Sensors and / or wiring to the 12V power supply


    As the sensor is described...

    Re: Proximity Sensors Gecko G540 and Mach3

    From your description I would of thought it should work as long as you only have one N/C limit switch / proximity sensor on each G540 input

    To prove the G540 is working OK

    I would...
