Ball screws are great, but cost about 10 times as much. BTW, ball screws are about 90% efficient, acme threaded rods about 30%, and bolt-type threaded rod is probably a bit less.]]>Jul 12th 2006 8:38AMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/Jul 12th 2006 8:50AMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/Oct 7th 2007 10:00PMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/Jul 12th 2006 9:16AMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/

I have a harbor freight micro mill that I converted to CNC and am now working a a 4'x8'x16"Z mill.

It got me thinking: how hard would it be to modify it, changing it from a CNC machine to a solder paste applicator?

What I'm thinking is that if it were reasonably easy, then this would be a great solution to the problem of assembling PCBs with modern SM ICs (e.g. BGAs and TQ144's); the proposed machine would read your Gerber file and put dabs of solder paste in the right places. Then you'd just place your parts on the PCB, put the PCB on a hot plate and you're done.

Thoughts?]]>Jul 14th 2006 10:43AMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/
As far as making a solder paste machine, it's completely doable. you just need to mechanize a syringe. Just make a mount that's similar to the dremel version.

If you want to make the syringe go up and down, you can add a fourth axis. There are enough pins on the parallel port to do it (if I remember).
If you can stand using a constant height, it's even easier. Just mount the syringe statically and use the z-axis to actuate it.

Also, The controller is compatible with TTL level inputs if you want to put a microcontroller in front of it for smarter controls or serial/usb interfacing.]]>Jul 14th 2006 11:18AMhttp://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/I am from INDIA working on PCB Soldering ROBOT.Could you please tell me how to convert Gerber files into G codes for Pads only and how to use that G code for controlling Motion.Is Mach and UCN58048 Controller will be able to solve our purpose.
Is there any other alternative to do this

Joel, to couple the threaded rod to the motor use a 0.25" I.D. rubber hose with two worm-gear hose clamps. I used air hose from TSC.
