    Re: Milling 16mm hole when it should be 18mm

    Hi thanks for the replies. The code is fine, so it must have something to do with my machine or mach3. If I set the hole to be 18,4mm, using mach3 as post processor in Fusion 360 and running a...

  4. Re: Problem with cranking up the current for steppers

    YEEEES! It worked, it is working so nicely now! Thank you all for your inputs. The setup is now as follow:

    PoKeys57CNC
    3 * NEMA 23 - 0.7Nm - 1/4" shaft (1=Z, 2=Y)
    NEMA 23 - 1.3Nm - 1/4" shaft...
  5. Re: Problem with cranking up the current for steppers

    Okay cool, and thanks for a fast reply. If ebay it has to be an european one, I live in Europe and I see that stepper online ships from within europe, so it shouldn't be a problem with them :)
  6. Re: Problem with cranking up the current for steppers

    Okay thanks for the reply rodw, it seems that I must upgrade my drivers, to get full performance then.

    I been looking around. Would something like this be good for a setup like mine?

  7. Re: Problem with cranking up the current for steppers

    Yes, it does say on the driver printboard max 40V, but yeah in the manual 30V. But I am thinking of changing the PSU to 36V, but then turn it down to maybe around 28V. Does that sound as a good idea?
  8. Re: Problem with cranking up the current for steppers

    I have been searching a bit more. I thought that maybe my wiring could have something to do with it. My drivers are wired in parallel and not serial, can this maybe have an effect that causes the...
  9. Re: Problem with cranking up the current for steppers

    Thank you very much for the chart wmgeorge. I am not smart enough neither to figure it out. The Y-axis is set to a very low velocity in Mach3 to have some torque and is running as I remember 1/8...
  10. Re: Problem with cranking up the current for steppers

    Ok so I should try to switch PSU to maybe a 36V? This is what info I have about the motors

  11. Re: Problem with cranking up the current for steppers

    The size is 1000m * 750mm



    Up to 2A for the three small motors and up to 2.8A for the large motor

    I have not connected any relays to the setup, I think it must be the PSU? But I really don't...

    Re: Mach 4 and Pokeys57cnc

    Ahh cool, it was my plan too to upgrade it with a lathe. But thought that one pokeys57cnc would be enough for that, because it supports up to 8 motors? My cnc is running now, but for it to be strong,...
