    Chris' G0704 build

    Well, after doing a bunch of research I've decided to convert a G0704. I looked at converting my RF30 but I don't have the time to make all of the parts manually and my quest to buy a RTR CNC mill (Dyna 2400) fell through 3 times.

    I've already ordered the G0704 from Grizzly and CNC Fusion's premium conversion kit.

    My plan is to use with Hoss' Digital Package (KL5056D drivers, 570oz steppers, 48V/12.5A supply) from Automation Direct.

    I still have a few blanks to fill in. I am planning to use a Lenovo Core i3 laptop. It doesn't have parallel or serial ports, so I am looking into the Ethernet Smooth Stepper.

    I'm also interested in getting a MPG. I've tried searching the zone for recommendations, but it fails when I try.

    This will be my first CNC conversion, so any input would be appreciated.

    Are you going to use the MPG for roughing, milling, or setup? I use a wireless xbox controller. Its no good for milling but its great for roughing and setting up.
    Just another option.

    Well, I've decided to dump the laptop. I don't need the extra headache involved with the USB/Ethernet setup. I can pick up a used Dell SFF machine with XP SP3 for around $80 off Craigslist. Even after I throw a monitor in I'm ahead of the game and there is less complexity to deal with.

    Now, for the pendant, am I correct in assuming that it connects directly to the PC? I think I will use it mainly for setup, but I can see using it to do some manual like milling too.

    I've decided to use the C35 board with the RJ45 connectors. I hate rats nest wiring and this should really reduce the clutter.

    I think I will put in my order for the the bulk of the electronics tomorrow. I just need to complete my list of odds and ends.

    An option for a pendant is to use a cheapo (about $6 on e-bay) usb game controller like the picture below. I have one and it works pretty well as a pendant for everything I have needed. I use LinuxCNC, but I know folks have used these in mach3 too. Just search for "usb joypad" on e-bay if interested.

    I have an Xbox 360 controller that I don't use very often. I suppose I could try it out for a while and see if it fills my needs.

    I placed the orders for the electronics today. I decided to skip the MPG for now. I have enough to figure out as it is.

    Here's what I ordered:

    Automation Technologies
    3 x KL-5056D Digital Bipolar Stepper Motor Driver-32 bit DSP Based
    3 x NEMA23 570oz/in 5A 3/8” Dual Shaft Stepper Motor (KL23H2100-50-4B)
    1 x 48VDC/12.5A Switching CNC Power Supply
    1 x Aluminum Controller Box (up to 4 axis)
    3 x Motor Cable with connector, 12ft

    CNC4PC
    1 x A1 - Parallel Cable
    1 x A36 -10FT Booted Cat5e Network Patch Cable
    1 x A30 - RJ45 Pass Through Panel Mount
    1 x C35 - QUICK SETUP BREAKOUT BOARD
    3 x C34KLD - Driver to RJ45 Connector Board for Keling's Digital Drivers
    1 x A32 Mechanical Switch Assembly to RJ45
    3 x IP40 NEMA23 Back Cover Kit
    4 x A26 - 1 FT Booted Cat5e Network Patch Cable

    Hopefully I didn't miss anything too important.

    I got an email with a tracking number from Grizzly this morning. My machine will be here on Friday afternoon.

    It will be interesting to see how the RJ45 pieces hook up.

    I got the stand cleaned up and ready for the mill to show up. I built this about 10 years ago for my RF30. The base is 2"x2"x.125" tubing with 2x3x.125" tubing for the top. It is 60" wide by 35" deep by 36" tall. It should have no problem holding up the G0704. I'm planning to add aluminum sides and a front plexiglass panel to keep the chips from getting all over the shop.

    I went ahead and picked up a Dell 745 SFF PC off Craigslist. $110 with a 19" monitor. It's got a 3.4ghz Pentium, 3gb of ram and a 128mb video card. It should be fine for running MACH3.

    My machine arrives this afternoon. I'm heading home from work in about an hour to wait for the Fedex driver to show up. I'm hoping I can get it up my driveway without having to take it apart.

    The box man came yesterday. The mill showed up at about 2:30. I had the column and head off in about 30 minutes. Lifted the three pieces up on the bench separately and had it back together by 4:30. I spent some time cleaning it up and doing the break in. I wrapped up and realized that I left the bellows off the column.

    I got this oiler off eBay for $65 shipped. Installing it will be my first project after I get the CNC conversion done. I will mill the oil passages when I open the carriage for the ball screws.Click image for larger version.
