    Re: 1st Build, will this be a decent Design?

    See Section 6 here:

    The DC voltage is 1.4x the transformer AC voltage. There will be a small voltage drop under load, but it's minimal....

    It doesn't really matter.

    What is G32?
  4. Re: G31 command stops since moving to Ethernet SmoothStepper

    What does your code look like?

    I know that several hundred ESS users are using my 2010 screenset, which uses a lot of G31 moves in macros.

    It's usually to enable or disable the drives, for drives that have an enable feature.

    Re: F360 - spiral toolpath on 4th axis?

    For wooden parts like that, get Deskproto, which can do continuous rotary. But I'd still do the joinery as separate toolpaths with indexing.

    People have been asking for continuous rotary in Fusion...

    Re: GME's New 80/20 CNC Build - My Design

    You can't look at it as an absolute distance.
    You have to use the angle deviation, and use trig (or CAD) to calculate the distances.
    And you also can't use an example of 45° angle, which makes...

    Re: Help with dual Y axis drives

    If you're using a parallel port, there aren't enough outputs for 6 axis and a VFD. But you could add a second port and another breakout board.
    Or go with something like an ESS with an MB3 breakout...

    Re: GME's New 80/20 CNC Build - My Design

    Actually, I had that backwards.

    Say you have a 6" beam, 6" above the table.
    Draw a line straight down and you have a 12" leg of a 90° triangle. The bottom of the triangle is your 60mm bit.
    Now,...

    Re: 1st Build, will this be a decent Design?

    A lot of guys in the UK just build their own. You just need a transformer, bridge rectifier and capacitors. There's not a lot too it.

    Re: GME's New 80/20 CNC Build - My Design

    If the ridges in the spoilboard are .001", wouldn't that mean that the beam is off by much less?
    Imo, .001" steps with a 60mm bit, is perfectly acceptable. That's only .0002" with a 1/2" bit.

    Re: Fixed Gantry Build

    Flanged blocks can be bolted from the bottom with the next smaller bolt size. Just drill and tap the plate from the top, and bolt them down.

    Re: Z-axis overshooting sometimes

    The encoders go directly to the drivers, so wouldn't be affected.

    As I mentioned before, you shouldn't be able to lose position with servos, as the drives should be faulting.

    Also, keep in mind...

    Y and A should have the same "Home Negative" setting. Did you always have them different?

    Try "Home Neg" on the one that moves the wrong way?

    Re: Looking for a CNC router to cut fiberglass+

    I don't think you can get chips from fiberglass panels, due to the fibers. And the tooling designed for fiberglass are more like burrs that endmills, so there's no cutting edge to cut chips.

    Re: Chinese 2.2kw spindle burned out?

    Assume that's it's probably not. I have two, and they are noticeably different.
    The proper method of preloading is with matched, ground bearings, which cost more than the spindle.

    Re: Chinese 2.2kw spindle burned out?

    You have to pull the "fan" off the back end, and then there should be a LH nut under it that needs to be removed. Then it will all come apart.

    Re: F360 - spiral toolpath on 4th axis?

    I thought that you could already do wrapping with Fusion 360?


    But wrapping is far from ideal in many situations.


    And as far as I know, Fusion still does not have full rotary axis support....

    Re: CRP PRO48xx rigidity?

    About as rigid as you can get without spending at least 2x more.

    Cutting aluminum on any router is always going to be a compromise, as even industrial $100K routers are not as rigid as mills. But...

    Re: Mach3 2010 Screen set

    Could be because the macro is sending g-code commands. The ESS must ignore the slave softlimit setting when jogging, but not when running g-code??
