  1. Breakout board and spindle controller for Mach 3 PMDX

    I have a PMDX-126 breakout board and a PMDX-107 spindle control for sale. They were removed when I converted from Mach 3 to a Centroid Acorn. They are high quality boards if you are using Mach 3. The...
  2. Re: Novakon nm-145 conversion to Acorn?

    I did not convert a NM-145 but I did convert a Torus pro. Is there anything specific you need to know?

    An acorn is a good upgrade. I will never use Mach 3 again.

    Re: Just ordered the last melon (Torus)

    Yeah like that one. I have never tried one so I don't know how the quality is. You will need a driver for it. If the stepper drive Novakon sells is ok they are available and not too expensive. Make...

    Re: Just ordered the last melon (Torus)

    You can use a butterfly impact gun if you want faster tool changes. It was what I was going to do before I splurged on the power draw bar.

    There are hundreds of 4th axis units on Ebay if 100mm...

    Re: Just ordered the last melon (Torus)

    I have recently had the same issue you did. I have an odd mix. For 1/4 and 3/8" I would advise buying solid tool holders. I'm not really in favor of collets to hold end mills. I have solid and collet...

    Re: Just ordered the last melon (Torus)

    Not going to like my answer but it's probably cheaper to buy whole sets of collets than to buy individual ones. The sets will be handy for things like drill bits but even with those limited sizes are...

    I might have one of the earlier probes. Maybe that is why it has a carbide ball. The stylus in my case was not bent so I tried to silver solder the ball back on the stylus but that was a complete...

    Re: How can I eliminate chatter

    Yeah I have to agree with you. When I first got the mill I bought a few solid end mill holders and a lot of ER-20 collet type tool holders because I thought they would be more versatile. I eventually...

    Good point maybe it is a rigidity problem. I do know some people here are successfully cutting steel with the same Torus Pro that I have. I'll order in a couple of stub end mills to reduce flex. I'm...

    Re: How can I eliminate chatter

    Thanks for the response. For Aluminum I use good quality YG1 or Iscar variable flute end mills. Aluminum cuts well and the finish is like a mirror.

    For steel I tried many different end mills. They...

    How can I eliminate chatter

    Hello All:

    Since my Novakon was new it has always had an issue with chatter. It works good for cutting aluminum but not on steel. When I try to cut steel it makes a squealing noise. Varying RPM...

    Re: Sunfar C300 Brake Resistor

    I had issues with the Sunfar VFD causing a lockup of the power draw bar due to electrical noise crashing the power drawbar. Under warranty and advisement from Novakon I replaced the Sunfar with a GS2...

    Re: Sunfar C300 Brake Resistor

    I think there is a lot of leeway in the wattage rating of the resistor. The rating given in the manual has to cover a lot of variables. For example the VFD may be connected to a conveyer belt (or a...

    I could not agree more about the acorn. It has been 100% stable. I put one on my Novakon to get rid of the frequent glitches I had with Mach 3.

    I would still check the input power of the VFD under load. Even with a plentiful supply at the wall it might not be getting to the VFD. A loose connection before the VFD can affect this. It's an easy...

    Re: Why I switched from MACH 3 to Centroid Acorn

    It depends on how your turret works. My turret uses a macro and does not take up an axis. If your turret is axis driven and you need more than 4 axis to make it work there is some good news. Centroid...

    Re: fusion360

    In fusion the engrave tool path is a bit misleading. Try using trace instead of engrave.

    Here is a video that explains it.
