  1. Re: Building Steel Frame Gantry Router for wood, MDF, and maybe more

    This discussion about brazing is interesting but the idea that you get distortion free assemblies without effort is just bogôus in my mind.

    In any event a quick aside. Fresh out of high school...
  2. Re: directionalized electrical noise detector

    Good electrical practice is hard to detail in a short post here. I’d suggest searching online for manuals from the electrical suppliers. Here is one that unfortunately isn’t machine controller...

    Re: movement problem with my CNC

    Good to hear you found the issue already. It sounded like backlash and apparently that is what you found.

    Re: Jake's 4x8 CNC Build

    Thanks for the updates! This machine is becoming a monster of a router.
  5. Re: Building Steel Frame Gantry Router for wood, MDF, and maybe more

    I have some comments here with respect to welder frames. Welded frames are use a lot in automation and the stresses welding builds into the frame are real. However there are ways to reduce the...

    Re: DIY project

    First; let me say that Mach 3 is on life support. That is the vendor no longer supports it so it can easily end up not working requiring a computer or application upgrade. Lots of people like Mach...
  8. Re: Vise attached to aluminum extrusion directly.

    I’m not sure I like the idea of machining any T-slotted aluminum. The stuff can be pretty thin to begin with. If the machine is close to square and parallel you might get away with it. In general...
  9. Re: Vise attached to aluminum extrusion directly.

    No memory on that one!

    I suspect though that you will need a precise frame to take advantage of a machine too vise. The problem is that yo have nothing to machine flat and in parallel to the X...

    Re: A poor mans CNC machine

    Yes cost of materials for the shop or even the house is expensive, especially at home centers! There are alternatives though, here are some suggestions:

    1. Tractor Supply is pretty good for...

    Re: 1.5m by 1.5m cnc at rigidity

    Bent steel or punctured steel is always impressive to see. Locally a guy driving a largish crane had that crane get loose while drinking under and underpass. That crane punched right through the...

    Re: 1.5m by 1.5m cnc at rigidity

    There is an endless number of ways to design and build a gantry beam. The vast majority of them can benefit from a machine shop. The problem with machine shops is the cost which is why everyone...
  13. Re: Is it at all possible to build a metalworking CNC router out of aluminum profiles

    Whoops didn’t notice that this is an old thread! However I wonder what happened with this project.
  14. Re: I need some direction on a new gantry build

    Are you certain thAt your issues are weight in the gantry? Frankly it could be a lot of things from detuned servos to backlash and a bunch of other possibilities. 200 pounds really isn’t a lot,...

    Re: Options for vac table pump

    The reason you get so many answers is because there are so many possibilities that any one could be the right solution. At the very best you only get the atmospheric pressure per square inch and...
  16. Re: What's the best method for automatic depth setting?

    No picture of your switch installation. I mention that because how the switch is actuated is a big part of repeatability.


    In the distant past I made use of a Baumer My-Com switches. Th...

    Re: Timing Belt Opinions

    Timing belts would be fine for a certain class of work, so the first question is what are your intentions.

    Beyond all of that timing belts for most router implementations are almost always...

    Re: A poor mans CNC machine

    I might mention that home centers suck when it comes to component costs. So not the best way to buy build materials, especially anything involving metal.

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

    The issue of blowing up a SMPS, from high bus voltages, is probably the best reason to avoid them. The alternative is to look for DC SMPS specifically designed for servo / stepper duty. The...
