  1. Re: X Axis; 2 ball screws, 2 steppers or belt drive from 1

    I’m assuming moving gantry here. A moving table design would be a different consideration.

    This is usual and for the most part good practice. That doesn’t mean other geometries can’t be made...

    Re: Rotary Router Lathe combo

    I may not be much help here as I’ve not done much Mac3 configuration but have a few suggestions:

    1. If you want lathe like functionality run a CNC controller in lathe mode if it has one.

    2....
  3. Re: New Machine Build - Massive CNC router for timber components

    Given enough time and money you can get any sort of machine orientation to work. A cantilevered gantry can work but it depends upon what one means by “work”. There are examples from metal...
  4. Re: New Machine Build - Massive CNC router for timber components

    Your time frame is pretty tight! This especially if you have a team with limited tool building/rebuilding experience. I’d almost certainly opt for something running or nearly so. Basically you...

    Re: My new DIY metal CNC machine.

    Very nice build.

    I do wonder how you keep the aluminum chips out of the salad though. ??????
  6. Re: New Machine Build - Massive CNC router for timber components

    The first thing that comes to mind is Mach3. Due to it being unsupported I’d seriously would consider another solution. Thankfully there are many solutions these days.

    I’m by far no expert in...
  7. Re: Is it at all possible to build a metalworking CNC router out of aluminum profiles

    Hi Ben.

    If you want some help create another thread. In this case though you just highlight a common result that people get when trying to build a router for Aluminum machining. That is a...

    Re: Change CNC Controlbox

    I’m trying to determine your motivation here. There are so many options it is hard to say what is best. The first thing that comes to mind is this does the current controller support drip feed or...
  9. Re: Cold weather affecting proximity sensors?

    This might not be much fun when it comes to finding the root cause. There are a few things worth trying that are not too expensive.

    The first thing to try is cooling suspected components with a...
  10. Re: Is it at all possible to build a metalworking CNC router out of aluminum profiles

    Your best bet is to convert the cost to a dollar per pound number. Obviously in a metric country that wouldn’t be pounds (in most cases). You can then compare that number to the going rates for...
  11. Re: Cold weather affecting proximity sensors?

    Most certainly temperature impacts electronic but 30°F really isn’t that cold. Have you narrowed this glitch down to one axis or switch? My thought here is that one switch might be flaky and...
  12. Re: Beginner design advice for small 24" x 24" machine

    If a laser cutter is in your future I would think seriously about an entirely different design. The reason is the rigidity of a router isn’t needed. Depending upon the laser chosen you can do well...
  13. Re: Wanting to build 4x2 4 axis machine. Where to start

    The types of stocks are a issue, short stocks for a shotgun or lever action will work better than a long thin bolt action stock in a fourth. You could address the long stock issue with a mid length...
  14. Re: Building Steel Frame Gantry Router for wood, MDF, and maybe more

    There are so many options when it comes to building a router that design paralysis can set in. Your best bet at building something that meets your needs is to detail what those needs are and what...
  15. Re: Building Steel Frame Gantry Router for wood, MDF, and maybe more

    Extrusions are not anymore flat than steel tubing. This is pretty much a function of the supplier. Now that being said extrusions often surpass the manufacture straightness specs but so does steel...
  16. Re: Beginner design advice for small 24" x 24" machine

    Doesn’t look too bad at all!

    When you say materials you will use is that to build the machine or are these materials you will machine? This is an important question because a move to...
  17. 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...
  18. 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.
  21. 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...
  24. 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...
  25. 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...
