New Machine Build- Emco F1 conversion

[slow_rider]

I want to convert my F1 so I can you Mach3 to run it...

The 3 axis kit I'm looking at is this http://www.probotix.com/3_axis_stepp...or_driver_kit/

The problem is that I want to control the spindle as well. It's a 180V / 3Amp / 440W (~0.8HP) DC brushed motor. If anyone has a suggestion for a "cheap" solution I'll be happy to hear it. Thanks!

Digital Machinist Magazine did a total upgrade of the Emco F1 mill, written by Eugene N. Niegoff. I bought the 4 back issues; winter '06, spring 07, summer 07 & fall 07, for about $26. The info was worth it, in my opinion. He upgrades using Mach 3 OS and Gecko drivers. I recommend reading this before beginning your project. He covers the spindle motor upgrade, also. I haven't started my upgrade yet, and I have no connection to the magazine, other than being a subscriber.

the original motormounts are standard nema size so most motors will fit rightaway.I'm replacing mine with 2.0nm steppers wich is probably way overkill.

about the spindlemotor
The driver thats controling your spindle right now is just fine.It has a 110/220volts ac input(depending on your region)and a 180volts dc output.For rpmcontrol a simple potmeter can be used for manualcontrol.I guess mach and a likes should be able to be programmed to output the right signal to this driver.i haven't been able to find out what the correct signal is but i assume that it'll be around 0 to 12volts were the 0 is 400/min.rpm and 12v is 4000/maxrpm

these were all the instructions i received with the purchase of my own emco f1 i've have yet to find an occasion to start that project.

pls keep us posted and throw in lots o pics and i will try to be as helpfull as i can be.
