  3. Re: Onion Skin Aluminum...how much do you leave?

    If you have a spoilboard and leveled it with the spindle, you should be able to get it pretty thin. I also try for around .004". Though with Mic-6, I actually onion skin all the way down to the...
  4. Re: Machining strategy for long, thin, plastic parts?

    Cutting long, thin strips may NOT be the best job for the tablesaw. There is a tendency for the sheet to lift and ride over the blade, and a tendency for one to attempt to push said sheet down,...

    Re: Tweakie-based 5-axis plans

    I'm pretty sure your configuration is A-C for the 2-axis table... A-B would be a gimbaled unit. A revolves around X, B around Y, C around Z.

    Like the others have mentioned, the uprights and...

  9. Re: How the CNC community probably saved my life

    Great work! Sorry about your past misfortunes. I've had some pretty bad times - and it got really ugly at one point - but I'm at a better place now, and when I'm working on my machines it has...

    If you have Mach3 then hit the tilde key (~) on the keyboard, will bring up the MPG screen then you can adjust the jog as a percentage of max velocity.

    Well for one, there's more aurface area on a square spindle for cooling. Second, since the body on the square spindle is aluminum extrusion, the aluminum can be more efficient at drawing away heat....

    Re: Skyfire CNC owners?

    I paid about $1100, not including ISF fee which I paid prior to shipping. In my thread I posted the process which I repost here for anyone interested and had no clue (like I did:)

    JerryBurks thread is one example, he went from similar steppers to 400oz-in and nearly doubled his performance.
  18. Re: 180-degree stepper lead screw coupling methods

    I'd tend to agree... an idler is really only needed when one pulley is very small compared to the other, over a short center distance, that there is not 180 degree tooth engagement on the smaller...
  19. Re: Cutting numbers in a circle? Advice needed! Use F-Engrave? If so what settings

    There's an icon symbolizing pocket cutting. You can choose raster or offset. Choose offset. DoC is depth of cut. Set the stepover to about 15-20% as these are small tools. I'd try 10ipm to...

    Running 6.52 on a WinXP laptop. Also can run it on Win7. For laser vector cutting you should be able to send HPGL, but it's been a while since I worked with laser.

    Re: Importance of ball screw pitch size

    Different pitches mean potentially different dynamics for each axis. Using a coarser pitch may necessitate using a larger motor to compensate for the decreased "gear reduction." Also you machine...
