    Re: Jogging motors

    Hi,
    if jogging is enabled it is certainly possible to jog....wouldn't be much of a CNC solution if it didn't.

    Mastercam is one of the oldest and most sophisticated CAM softwares out there, if you are familiar with it it would put you in a good
    place for employment. The downside is that its hugely...

  5. Re: Understanding Backlash tests and fix options

    Hi,
    some CNC solutions like Mach have a 'backlash setting' but there is NO real software solution to backlash.
    Preloaded ballscrews have zero backlash and that is what makes them so popular with...
  6. Re: Lost position with closed loop stepper motors! Nightmare! Please help!

    Hi,



    No, it would be 640,000 pulses per minute so 640,000 / 60=10,600 pulses per second or 10.6 kHz

    Re: Please help with wiring and MACH 4

    Hi,
    the ++ and -- terminals on your power supply are just that, the +ve output and the -ve output. There are two +ve's, so you can use either one or both,
    likewise there are two -ve's.

    You just...

  9. Re: Looking For Examples of High Lead Ballscrews With Gear Reduction in Z

    Hi,
    according to the manufacturer the stepper/gearbox combination has a holding torque of 8Nm, and when coupled to a 2005 ballscrew its

    Re: Where to start? 3040 parts upgrade

    Hi,
    I think the issue will be rigidity, or rather the lack of it. You will be able to engrave aluminum with that machine but its just not rigid enough
    to 'mill' aluminum.

    My suggestion is that...

    Re: Pokeys57cnc and THC in mach3 or 4

    Hi,




    If you are using Mach4 then definitely the ESS/TMC combination has much to recommend it. Note the TMC unit is reasonably pricey, so while its a good
    solution you will pay for it.

    Hi
    60mm is an IEC frame size and is slightly larger than NEMA23. I'm not sure that NEMA24 is an 'offical' NEMA size but it is a drop
    in replacement for a 60mm IEC motor but as you have discovered...

    Hi,
    that spindle is rated at 3.5kW at 18000rpm.

    torque in Newton.meters Nm
    speed in radians per second s-1

    Re: Pokeys57cnc and THC in mach3 or 4

    Hi,
    the Mach4 implementation relies on Mach4's scrpit based THC feature, it does not mean that the 57CNC is implementing realtime THC control.
    Realtime control is desirable because the closed loop...
  25. Re: Home Switch setup ESS G540 and Mach 3

    Hi,
    you need to post this question to Andy on the Warp9 forum.

    It sounds like Mach is not interpreting the switches as homes when you are in homing mode.

    It may or may not suppoort realtime THC in Mach3, I just don't know. I would suggest e-mailing PoKeys with...

    Re: Hybrid stepper motor.

    no doubt there are many high torque 23 size motors but they also have high inductance and you need to avoid them.

    All steppers lose torque the faster they go. Winding inductance is the...
