    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??

    Re: Chinese 2.2kw spindle burned out?

    You need to unscrew the big aluminum nut on the bottom with the holes in it, using a pin wrench or spanner.

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

    Probably because they are very heavy. There are a couple DIY CNC suppliers in the UK. They might carry them, or something similar.

    Re: Mach3 2010 Screen set

    The macros (and screenset) have nothing to do with softlimits. I'm guessing that it's the way the ESS deals with macros and softlimits, and is probably a bug in their plugins.

    I'd contact Warp9...

    Re: Mach3 2010 Screen set

    It might be something to do with the ESS plugin and how it handles softlimits.

    Re: Looking for some guidance

    Do they accept analog control? There are a few Mach3 controllers that can run analog servos but they aren't cheap. Linux CNC can control analog servos as well.

    I don't think there's any other way...

    Re: Mach3 2010 Screen set

    It should work fine with the ESS.

    Have you tried restarting Mach3? Or rebooting the PC?

    Re: Choice of 2 steppers, which is best?

    The rated torque is the holding torque, when the motors are not spinning.
    Once they start spinning, the torque will fall off rapidly. The higher the inductance, the faster the torque falls off.
    So,...

    Re: Z-axis overshooting sometimes

    I still think the coupler is loose, and the lack of lubricant caused it to be noticeable. Adding lubricant lowered the torque requirement, so it's no longer slipping. But, it's still loose.

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

    I'd use a minimum 48V power supply, or even a 60V supply. For four of those motors, I'd get a 15amp supply. Something like this.

    The AXBB-E does not require a breakout board, unless you need to use it's expansion port.

    Yes, you need a power supply for the motors. What are the specs of the motors and drives? The higher the...

    Re: Z-axis overshooting sometimes

    The nut still may be binding, causing the couplers to slip.
    The motors should fault if they lose position, so you aren't gaining or losing steps at all. Must be a mechanical issue.

    Re: Z-axis overshooting sometimes

    If you have Clearpaths, then you can't be losing steps. The coupling may be slipping? Yes, you should definitely be lubricating the nut.

    1) I'd go with a 3-4KW spindle, as long as you get the Nema 34 motors.
    2) You'd need to ask Avid about that. I would think it would be a problem, but you may find the Z axis will drop with the...
