  1. Re: Shopbot PRT Alpha, upgrade to Acorn / Gecko g251x, power supply question.

    Powering the steppers with less than 48V will result in poor performance.
  2. Re: Rookie question on minimum spindle speed of a HSD spindle

    You could call HSD and ask them.

    The data sheet shows a torque curve starting at 200Hz, or 12,000 rpm. I'd stay above that.

    Re: enroute and aspire

    Cabinet Solutions website has basically zero info on their cnc export.

    You need to learn and understand how the process works, before you spend your money.

  5. Re: Way cheap downloads for Aspire on Ebay - are they for real?

    They are pirated, illegal copies.
  6. Re: Beginner design advice for small 24" x 24" machine

    If anything, I would say you could go bigger. Everyone wishes their machines were more rigid, and more powerful.



    Almost everyone uses C7 screws, unless you want to pay 5x more. But unless you...
  7. Re: Wanting to build 4x2 4 axis machine. Where to start

    If you can do the fabrication yourself, you can build a rotary axis similar to the Avid 4th axis for less than half the price. It's not much more than a motor and gearbox, with a chuck mounted on the...

    Re: Mach4+ESS or Acorn?

    My understanding is that the Acorn does not work the same as the ESS or CNC Drive controllers.
    I beleive the Acorn does the trajectory planning in hardware, rather than in software like all the...
  10. Sticky: Re: Router Bits and EndMills: Pictures, Descriptions, and Uses

    Looks like it's just pocketed. In that case, use the largest straight bit that will give you the detail you need in the letters. This may require a very small bit, which can take a lot of time. You...

    Re: Picking a stepper motor

    Oriental Motor (Vexta) is one of the top brands.
    Most people buy no brand Chinese steppers, as they tend to be much cheaper, and still perform well.

    I posted a link to your post on the JointCAM forum. Thanks for sharing.
  17. Re: AVID CNC PRO 48x48 Purchase (Mach 4 Concerns)

    I wouldn't worry about it, as Avid will provide excellent support for it.
    There are probably well over 100,000 Mach3 users, and anyone that's used both will tell you that Mach4 is much better....

    Re: Mach4+ESS or Acorn?

    Depends on the programs. There are cabinet programs that can generate g-code themselves.
    But you'll still need a machine control program.

    Re: enroute and aspire

    What are you expecting to do?
    Does your Cabinet Solutions export .dxf files and a cutlist or parts file (CSV)?
    I believe that the Pro version of Enroute can work with that much better than Aspire....

    Re: ESS MB3 Index homing

    Sorry, I'm not familiar with Mach4 homing.
    But I would think to home with both a switch an index pulse, you'd need a custom homing script?

    Enroute comes in different versions, with different levels of features. Enroute Pro is much more powerful than Aspire, but costs more than 3x as much. They also have a subscription for $1100/year....

    Re: ESS MB3 Index homing

    Are you using Mach3 or Mach4?
    What do you have the index assigned to?
    In Mach3, once it backs off the home switch, it's homed, and won't move to the index pulse.
    Not sure if mach4 can use both.

    Re: "equal to" operator not working in script

    The scripting Mach3 uses, Cypress Enable, is a little different than VB, which is why I added the Format above. The Format returns a string, so you'd need a different function to get rid of the...
