  1. Re: Lost motion/backlash...gonna have to dive in.

    A DRO on a CNC mill control panel as shown by the movement on the readout is not a DRO per se........it is indicating the rotation of the ball screw and that is as good as a manual mill with just a...
  2. Re: Lost motion/backlash...gonna have to dive in.

    Hi, a lot will depend on your engineering skill ability as far as metalworking goes.......I would not advise touching the dovetails with anything except an oily cloth as they need to be fitted very...

    Re: Using Treadmill motor on Metal Lathe

    I suppose you already had the parts from the TM but my 2 pennoth worth would be to buy a 1 HP 3 phase motor and a VFD......did that for my small lathe and my mill too and it was a ten second plug and...
  4. Re: Lost motion/backlash...gonna have to dive in.

    Sigh....those dammed dovetail problems......now you know why linear rails were invented.

  5. Re: Converting a CNC boring machine to full 3-axis

    I would have thought the first strep would be to drive the spindle from a completely separate power supply, that is completely separate......I get the impression from your characteristics that if you...
  6. Re: 'Reference Face' for a steel CNC Router build

    You did not mention the size of the build or your skill level.
    For a small build, like a 3040, you could obtain a piece of granite counter top and use that as a reference surface plate to build...

    Re: GRBLGRU looks great BUT...

    As I'm building a 3018 from the ground up with upgraded specs but mainly for a fun exercise to see what it can do after it's beefed up, I'm going to go with Mach3......GRBL is too different to...
  9. Re: Newbie looking for advice on first cnc purchase

    You could always build one as a guy in Tasmania is building a midi CNC router on UTUBE at the moment.......1 metre X 1 metre .......approx A$1500.

    Re: basic upgrade..!!! help

    I have to wonder where the reference to the 3018MX in post #1 went to.........no reference to a 6040Z anywhere here.....highly confused.

    Re: I hate cnc .....

    I'm a golden oldie from the old school of machining but when I retired I decided to dive into the pool of CNC to experience the computer managing the machine moves.

    I don't have parts to make or a...
  13. Re: My first CNC - a small 3018 chinese cheap machine

    Yeah, I suppose I could consider Mach 4 if I knew it was user friendly and worked with my present knowledge of Mach3 which as a complete wet and shaking noob is the extent of my limited knowledge of...

    Re: Torque for ER20 and ER32 collets

    So, what is all the fuss about then......tool pull down with TTS or cutter runout with any system?

    I think you can get total cutter concentricity with all systems if you're lucky enough with your...

    Re: Torque for ER20 and ER32 collets

    You are quite right in the capacity being worked....if it overcomes the holding force of the draw bar system it probably will do some damage elsewhere etc......provided the Bellville washers are...

  17. Re: My first CNC - a small 3018 chinese cheap machine

    Re: basic upgrade..!!! help

    You are going to use a 2.2KW spindle on that tiny 3018 router???.....wow, that is asking lot for the frame to hold together while cutting.....unless I'm mistaken with the MX3 model of the 3018 type...

    Re: Chinese 2.2kw spindle burned out?

    It would probably be cheaper to give the VFD's and the motor(s) to an expert repair person and get an opinion on the condition of both.......he(they) will know more about setting it up to suit your...

    Re: Torque for ER20 and ER32 collets

    Hi, what you are missing is that the TTS system is a spring loaded draw bar that applies tension to the collet to hold the tool shank in.

    It depends on the amount of spring pressure the Bellville...
  21. Re: CNC 3018 Y Axis - horrible jogging noise

    Well now........having been a UTUBE browser for a long watch into the middle of the night on quite a few occasion the 3018 mini router caught my attention as a fun thing to do.

    Re: Torque for ER20 and ER32 collets

    I never did like the TTS system......at the same time I've never had to use the TTS system as I have ER32 collets in chucks that have ISO20 tool holders, but the concept is one that relies on brute...

    Re: Chinese 2.2kw spindle burned out?

    I'm all for innovative ideas but I think in this case the end product will take twice as long as the...
  25. Re: Fixed gantry or column for mill rigidity?

    A question or two......do you really want to build one for the experience or for economy.......and do you want to use it for production for saleable items or mainly hobby use?

  27. Re: Fixed gantry or column for mill rigidity?

    For a table that width size you will have to have a bridge mill design.....a single column will not support the over hang for the Z axis to reach over the full width of the table you plan have but a...
