    What's your paint process for MDF? Hands down the best finish I've seen.

    On the download page for the C76 is a plugin that will show you where the fault is in UCCNC.
    Here's an example video of it.

  3. Re: Minimizing tearout on CNC router - wood types and other tips?

    Depends on the types of cuts you are making. Generally, harder wood will cut cleaner. I find poplar to be quite difficult, but it depends what you are doing with it. Also note that poplar can vary...

    Re: CNC Spindle Control, PWM to 0-10v

    Try setting PD070 to 1 for 0-5V control.

    ±500 RPM isn't going to make much difference.

    On my Huanyang, when using analog control, I had an RPM variance of ±1000 RPM with a steady analog...

    Use a profile cut with a single vector set to ON the vector.

    You probably wouldn't see much difference going to a drive that can supply the rated 4.2a, unless you also increase the voltage to around 70V. And at that...

    If you are trying to get the most speed, you need to increase voltage to the motors. Different drives won't make that much difference.

    Re: Rotary Vane Vac pump, sudden odd noise

    I can't believe that rust would have caused that, especially after 15 minutes of run time. If it was rough enough to break them, it would have been very loud from the start.

    I just replaced the vanes in our two pumps, and the new vanes come with the beveled edge. You can probably flip them, but you'd probably get a lot less vacuum until they wear in.

  21. Re: Replacing steppers for more torque options / Advice wanted

    1) What is 320NM? NM is a torque rating. If it's 320 Newtons, that's about 72 lbs, which is higher than you'll likely ever see.

    2) It really depends on the drives, and without a torque curve chart...
  22. Re: G540 / UC100 Controller Build for GenMitsu 3018 routers

    Get a UC400ETH instead of the UC100. It's more powerful, more expandable, and has much better noise immunity than a UC100, for only about $25 more.

    Re: 3D Toolpath Not Machining Thru Holes

    I just made a similar model to yours, and it works fine.

    You're doing something wrong, but I'm not sure what it is. If you can upload your model and Aspire file, I can take a loot at it.
