Can you give us some background on what wavelength safety glasses you are using and how you are protecting yourself and visitors while the unit is running? I am looking at adding a Co2 tube to one of my Routers. Engraved signs are good idea, but my health and all safety factors are more important. I purchased a 40watt cheap unit from www.lightobject.com including the DSP. Everything works pretty well, for less than $2500, My intent was to learn so I could add a larger unit for one of my gantry routers. The Unit I purchased needed quite a bit of engineering upgrades but nothing that can't be overcome.
Thanks
Keep up the great thread

Using Version R3.043.038
I get a message "Contact Brian BUFFER ERROR"
about every few minutes after running it.
Wish it was a real time display, while jogging it waits till I stop before updating LCD.

dspMC/IP Motion Controller / Re: New Win7 install not connecting

win 7 32 bit or 64 bit

?

Different drivers for each OS and some computers don't have both working well. Took me a long time to get a three boot up system to work (win 7 ultimate 32 & 64bit and XP SP3 on a 500GB sata drive with 3 partitions)
Never give up. :-)

What material is the Distributor cap made of? Looks like you will be able to see the spark when it fires. That should be interesting.

I must have missed when you polished and engraved the rocker covers. Looking nice.

Looks like your close to filling it with Torco?

General Mach Discussion / Re: Cnc table top surface skimming

« on: May 13, 2011, 08:04:36 AM »

here is a program I created to face stock, you can adapt it to your needs to surface your table top.
You can make multiple light passes till it cleans up. Play/learn with it, till you understand what it can do for you.

Code: [Select]

    (CUTS Top Face of stock)
    (STARTED AT Z0 TOP OF rough PART)

    M03 (start spindle)
    G1G90X0Y0Z0.25F60. (Go to lower left corner of stock)
    Z0 ( Feed to face of rough stock)

    (load variables)
    #1000=[2] (Length in X in this case inches)
    #1001=[2] (Width in Y)
    #1002=[-0.1] (depth each of cut pass)

    #1004=0 (Top of part)
    #1005=0.65 (offset cut distance smaller than .75 cutter diameter)
    #1006=[#1005*2] (Compute step over)
    #1007=[#1001/#1006] (Compute passes)

    M98 P5 L8 (call subroutine CUT DOWN IN Z in this case 0.1 * 8 = .8")
    M05 (stop spindle)
    G0G90Z.25 (move back up)
    X0Y0 (go home)
    M30 (All done)

    O5
    M98 P10 L1 (call sub to feed down)
    M98 P20 L1 (call sub to face part)
    G0G90Z0 (Move out of the way)
    X0Y0 (Go Home)
    M99

    O10
    #1004=[#1004+#1002] (Calculate New cut depth)
    G1Z[#1004] (MOVE TO CUT DEPTH)
    M99

    O20
    M98 P30 L[#1007] (call sub to cut reps ACROSS)
    M99

    O30
    (THIS IS THE SUB TO CUT FACE)
    G1 G91Y[#1005] (Increment over in Y)
    G90X[#1000]F80. (Cut across part)
    G91Y[#1005] (again increment over)
    G90X0 (Cut back across part)
    M99
