    Re: Nema 34 on Ballscrew Systhem

    Re: My CNC Build

    I did think about building a moving table machine but I just don't have the room in my shed for it. In the OP photo he has two "Y" axis ball screws so racking shouldn't be a problem with the close...

    Re: My CNC Build

    You are right there, I built a table for my router from welded steel 50X50X3mm. The trick was to bolt on the two "Y" axis support rails at the ends only and then ensure they are level with an epoxy...

    Re: My CNC Build

    That is a strange size for a wood working router, sheets of ply and MDF are only 1220 wide. The Nema 34 motors are way overkill, you can only run a ball screw up to 1000rpm but with cheap drivers the...
  5. Re: Off Topic but still relevant - Amazon wont ship to South Africa !!!

    Probably a bit late now but why don't you get the parts direct from the China on DH Gate or Alibaba? I bet that is where the Amazon sellers got their stock from or drop shipped.

    Re: CNC Router Metal Engraving

    Thanks Ian for the heads up. I have only been using the dust extractor to remove the smell as my set up is in my bedroom and Innox and WD odours hang around for a while but I hadn't given any thought...

    Re: CNC Router Metal Engraving

    Hi Ashley. I was just having another look at your OP and there are a number of ways to bring your project into being with your budget. First, don't pay more than $50 for a PC. Most controller...

    Re: CNC Router Metal Engraving

    Hi Ashley

    There are many different recipes for cooling and all have their merits, I only choose WD40 on metals as it is convenient and my dust extraction removes the smell, but I also use others...

    Re: CNC Router Metal Engraving

    Clamps are something that you will have to make yourself or have made. To be able to hold those pieces down to the table you get a lump of ally at least 12 mm thick and pocket out holes to exactly...

    Re: Importing a machine from China or the us

    There are importers of machines here in oz that have already taken care of all the problems to do with self imports and provide a warranty that you can enforce.

    Also, most of the kit machines sold...

    Sorry mate, can't help much but I looked at that system and found like you that the cost was over the top and went for 16 mm supported rails..worked out much more cost effective in the end and also...

    G'day tricarpa

    The reason that you won't find any formulae for what you want is because there are too many variables to make a any formula work...the type of wood, how old it is..ect. As you...

    Re: Stepper motor power

    Hi Dave

    I was in the same boat as you...I had no idea how to relate the various inch/ounce ratings to real world practice. I bought some Nema 34 1600 ounce?inch motors and a 1605 ballscrew to...

    Hi Roger

    Sorry for the delayed response..for some reason I haven't been able to log into the Zone. I am sorry but I have had to google most of what you say...I don't even know how to really run...
