Ohh dear. 

With a bit of luck it is just the 1000pF silver mica which has expired.

Here is the RF board schematic (assuming you have the version with just one single RF output transistor).

Well, that's that then as the forum limit is 6MB.

(I regularly run code in excess of 340,000 lines which zip to less than 4MB).

Chad,

May be an idea if you post your GCode, this way it can be established if it is the fault of the code or your setup.

Rich,

Looking at the grain structure of that magnum - is it usual for S & W to use a casting for the chamber ?

Hood,

Just keep your chin up, everything will be OK.
We all need your speedy recovery.

General Mach Discussion / Re: cnc for milling out a circuit board

« on: May 02, 2011, 04:22:25 AM »

I did a trial run on your GCode and the results are not good.
Your design lends itself better to acid etch than it does to routing mainly because of the fineness of the tracks. The loading which mechanical cutting puts on the copper substrate can approach the bond strength between the copper and the board when such fine tracks are milled and as can be seen from the photo part of the tracks are missing.
If you thicken up the traces, you may be in with a chance but, as it stands, this design would be extremely difficult to produce with a router.

Hi Kevin,

It would be best if you used shielded wire for your switches and estop (shields connected to ground at the controller end only, preferably to one single point).

Ton,

In this config. I have used Output#1 for the spindle CW and CCW and this is mapped to my Port 1 Pin 1. You can choose any output pin you have free.

Ton,

I already had a spindle setup on my machine using the M3 and M5 commands for on / off. As the air application did not require the spindle I used the spindle 240 volt supply and spindle relay to power the solenoid via a small (wall wart) transformer. http://www.machsupport.com/forum/index.php/topic,12168.msg78104.html#msg78104
