    Have you checked with Biesse?
    I know that SCM offers a Morbidelli post.

    Re: Feed and Speeds for CNC Machine (Plywood)

    You can run this bit 1/2" depth of cut, 17,000 rpm and 700ipm, if your machine can handle it.

    Never used a 4 flute 1/4" bit, but I've run 2 flutes at 400ipm. In theory, you can go twice as fast...

    Re: ball screw help/suggestions

    So you don't spin a 60" long 16mm screw at 3000 rpm.

    Re: ball screw help/suggestions

    If you are using steppers, you want between 10mm and 20mm pitch. With servos, I'd go 20-25mm pitch, and use a belt reduction from servo to ballscrew.

    Re: CNC Wood Router Lollipop Bits

    The best tool to use depends on the specific application.
    As a general rule, you can get away with feeds and speeds for a similar size woodworking tool.

    I'd recommend either a UC400-ETH or UC300-ETH, with suitable breakout boards.

    Re: Should I give up on Mach3 in Windows 10?

    Don't get too hung up on importing your Mach3 profile. Easier imo to just right down your port and pin numbers and enter them manually.

    No, they don't lie. But you can't import settings into UCCNC that don't exist in Mach3, or import Mach3 settings that don't exist in UCCNC. The settings that are in both will import, but there will...

    Re: What stepper driver should I use

    425 oz Nema 23's are usually a poor choice, due to their high inductance, unless you run them at 60V-72V. Motors in the 300oz range will usually outperform them at lower voltages.

    I'd rank them all above Hiwin. In reality, if you compare apples to apples, there shouldn't be any discernible difference between them.

    I'm building a wood 4x8 machine, and am using a square torsion box gantry, roughly 200mm x 200mm.
    I'm using laminated MDF for the torsion box, because it was free.
    Here are a couple links.

    Re: Belt gearbox for helical rack

    Belt drive probably has less backlash than 15 arcmin.
    Gearboxes tend to be higher reduction, and are designed to work with servo motors.
    5:1 belt drive is designed for stepper motors.

    It should work fine, but the axis that moves vertically will definitely move slower, or at least accelerate slower. A bigger stepper may or may not help, as bigger motors tend to have even less power...

    Re: UC400ETH HY VFD Control

    The easy way is with the HY modbus plugin and a $10 USB-RS-485 converter.

  25. Re: HY02D223B VFD - Simple Forward, Reverse, Stop. How do I do it?

    Yes, you are correct. No earth required, as it's just low voltage DC.
    However, you might want to locate the buttons so you can't accidentally hit reverse when it's running in forward.
