View Full Version : Small improvements to my Mikini.

It's been awfully quiet on these forums, so I figured I would post a video of some of the changes I made to my Mikini. I have been making a bunch of scrap, in my quest to learn this cnc stuff. The mill has been running, but, I'm still afraid of really pushing it.

I upgraded the computer .....again. Mostly for aesthetic reasons and the fact that I found the new computer on ebay for only $30.00...case and motherboard. When the package arrived, I was thrilled to see it was brand new, never used. I popped in a Intel dual core and some ram, loaded Xp and Mach3 and the Shuttle booted right up :)

As I have mentioned before, I also installed a Smoothstepper motion control. I mounted it in the case of the PC. I'm really impressed by how nice the steppers run. I made a new jig for my linkage system and I couldn't be happier with how nicely the mill ran.

Anyway, here's the video. Some of the stuff you may have seen before, but, i just wanted to find an excuse to use my camera...lol

Nice! What's the captive drawbar? I'm working on installing an exhaust system so it can vent out the air within the enclosure to the outside. The wife goes ape**** when I machine because it makes the whole house smell like way oil. I'm using a bathroom exhaust vent, some tupperware, and some dryer vent.

Well that's what I'm calling it...lol. I don't know if i have an original Mikini draw bar. but, I have to tap out the R8 collets when it comes to a tool change. In the following picture, you will see that i don't have the Mikini cover in place for the drawbar.


If the cover was in place, the nut of the drawbar would be covered. I want to extend the hex portion of the drawbar, so it fits through the Mikini cover. I will also machine the new drawbar so that it would push against this cover and basically push the R8 collets out...instead of tapping them out with a hammer.
