    Re: CNC is not working properly

    Compare the file that was fixed to the original one that didn't work. Pay particular attention to the initial string of characters, which may have contained a command that was causing the file to...

    Re: CNC 6040 - issue with working

    I'd look for mechanical issues first, like a coupler or pulley that's slipping or a bearing that's loose. If you can't find anything like that, try reducing the acceleration on any axis that's not...

    Re: Toroidal Transformer hookup

    Usually, stepper drivers run on DC, not AC. If yours really runs on AC current, you won't need the transformer, which puts out DC electricity. But the 18 -80v specification sounds more like DC than...

    Re: CNC cuts 25% larger than design.

    Have you measured how far each axis moves when commanded to go a certain distance? The simplest explanation is that your steps per unit need adjustment.

    Re: Aluminium printer/milling machine build.

    Have you made a picture of this thing? I'm trying to visualize it - especially the part about it building its own Y axis as it goes - but not having much success.

    I'd suggest using steel beams...

    Re: running ten stepper motors from PC?

    The most I've seen a breakout board control is 5 axes. Maybe you could gang up two of them. But you'd still need a separate driver for each motor. If the motion you need is pretty basic, maybe a...

    Re: New Taig Mill

    Taig offers two controllers for their mills. The basic one is an open-loop half-stepping system that's generally reliable with Mach3. The more deluxe DSLS (Digital Servo Lock System) counts steps as...

    Re: Z Axis Slips during Pass

    Could the tool be slipping in the collet? The helix on an endmill tends to put downward pressure on the tool as it engages with the material, and it can be dragged downward. Try putting a mark on the...
  11. Re: CNC Router - concept to allow a huge

    Points given for innovation here, but I don't see this working too well. By lifting the whole gantry beam for each Z move, while the spindle is fixed in position, you lose the ability to descend into...

    Re: Want to build a cnc drilling machine

    If the holes are all in a straight line down the middle of the tubes, it seems that you should be able to build a 2-axis machine fairly easily that would do this for you. Think of an easily loadable...

    Re: Speeding up my stepper

    My guess is that you're running high-impedance stepper motors with insufficient power. GRBL systems usually have that problem. Gearboxes aren't usual on stepper driven CNC systems; they make them...

  16. Re: Can I kindly ask for your help? EdingCNC 720

    I don't think there's a problem with the X and Y machine origin coordinates being negative numbers. That's just a reference point; the origin your G-code will work from are the "floating zeroes" you...

    I'd say either your limit switch isn't working, or the signal from it isn't reaching the control panel.

    Re: Breaking Bits

    It sounds like a problem with the depth of cut at that feedrate. If a 1/4" cut works fine, but your bits all snap when you cut thicker stuff just as fast, either change the toolpath to only cut 1/4"...

    Re: bits 1/8 vs 1/4

    A good compromise is a tapered ball-nose bit. You get the point for detail, but the shank is thick enough to keep it from breaking too easily.

    Re: Thread mill steel

    1/4" is a bit small for thread milling. I'd use a tap instead. If you've got a Procunier or other tapping head, this would be in its sweet spot.
