  1. Re: CONFUSED... Where to home too... Help! where should my home switches be.

    I put them on because it cost me $20 and I don’t need to brainsweat as much. My inductive switches made 1/2 a thou as well. More like .0003.
  2. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    Also a point of annoyance - your controller may closed loop operation. Or the encoder may only drive the LCD.

    The mechanism I use does not support closed loop - and you cannot do closed loop...

    This is the control board I use for this.
  4. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    So controlling spindle operation will be doable via analysis of your reversing switch.

    This switch will most likely have a voltage or ground that is switched when you turn it. This will be...
  5. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    So here is my analysis of whats going on so far:

    1. Your Controller VI may not control the spindle at all. Nothing. It may only want to control the axis motion.

    2. You have a standard...
  6. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    Interesting. That is a 2.2KW closed loop BLDC drive.

    X3 is motor drive power.

    X7 is the hall effect sensor for the motor.

    Are the X* connections marked on the main board?

    It says X6...
  7. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    That is much fancier than a KBIC. It probably has an integrated LCD for spindle speed.

    Is optimum still in business? And any chance you can find a part number on this board?

    I’m...

    Re: AMAT25LV Basically another PM25 clone :)

    I had some of these same experiences in my build. I used hybrid steppers if you haven’t done the purchasing yet.

    Much quieter and I’m able to wire in an alarm setup so it works well in that...
  10. Re: New member - Spindle setup Optimum BF 46 with UCCNC

    So i do this with the c76 board from cnc4pc. But on a KBIC controller. On a g0704.

    Chances are high that you have a KBIC clone controller inside the spindle control box.

    If so, yes you can...

    Re: Vectorsc’s G0704 Conversion

    Single nuts unfortunately. The other main issue I have is that they don't have a wiper on them to wipe any chips away so you have to be super anal about guarding them.

    Re: New UC300ETH breakout board.

    What is a practical max step number for the uc300eth? I’m mostly interested in quieter operation of my machine. i have about a 5:1 ratio so at 800 steps per rev I have about 4000 steps per inch. ...
  16. Re: My spin on the G0704 - I pretend to know what i'm doing

    What was the biggest challenge? I mean compared to him milling the ways off to use linear slides and such. And he has the new column already it looks like.

    Not doubting you - you have done...
  17. Re: My spin on the G0704 - I pretend to know what i'm doing

    So odd note. I would finish the 0704 mostly stock and see if you can sell it. Why? If you are making your own column and using rails just go all the way and go full custom. Maybe order just the...
  18. Re: My spin on the G0704 - I pretend to know what i'm doing

    So a fun note - what happens when you add gussets to the existing column? Heck, you could almost capture the existing column within the i beam pocket and bolt it down.

    G0704 Stock Spindle Encoder Pinout

    Does anyone know the stock encoder pinout? Haven’t been able to find it.
  20. Re: Double ball nut worth it for long C7 grade rolled ball screw?

    Also I hate to add to this, but based on my research (and not experience) you might want a c6 screw for an almost 1 meter span.

    Re: Vectorsc’s G0704 Conversion

    I liked some of the features, and I think the whole world must need something higher profit margin than these G0704 kits right now...

    Yes - I mean closed loop steppers.

    Great feedback sir - and the steppers I'm using are 3NM or 428oz/in. I meant to say quantity 2 not 2.3NM. Oddly I have heard that due to the closed loop...
