Jason, Nice Job. I'd be interested in the g-code for that if you wouldn't mind posting it.

Maybe a better place to post the g-code might be http://www.cnczone.com/forums/forumdisplay.php?f=152 . Actually, I think it might be nice to have a new category under 'Machine Controllers Software and Solutions' (http://www.cnczone.com/forums/forumdisplay.php?f=69) just for posting shareware g-code).

No problem Rance, I will post the 5/16 hole size as well as the 6mm hole size (motor shaft) and the star, the 1/4" hole code needs a correction.

*********The code is in mm!**********

********Please note that the code requires use of a 1/8" bit.*********

*************The 1/8 bit should have a 1/2" Depth of cut.************

Joe,

I forgot to indicate my set screws are 3/8" long so I have thread contact right through the stock to the shaft hole. What was the length of your set screw?

Oh ok that will help alot mine were really short.

I decided to get some Lovejoy Couplers for my JGRO, I found some at Surplus Center at $2.19 for each half plus $1.49 for the insert, a total of $5.87 each. I did not know they were that cheap so I bought 6 - 1/4 halves , 6 - 5/16 halves as well as the inserts. The extra couplers will go on my Hawk mill for now as I have not had the time to fit the homemade ones.
These couplers are allowing me to jog at a faster speed as compared to the rigid couplers which leave no room for error.

The lovejoys are working well but I noticed as others did that the rubber spider inserts allow a little backlash if the size is slightly off. I therefore tried my hand at designing and cutting out some inserts as Joe did and they came out quite well.

I am yet to determine the performance of the home made inserts but I will post it in the zone.

The good thing about these small parts is that they can be produced from offcuts of material lying around.

I have not had a chance to test the plastic couplers on the little machine yet
but I should have time this weekend

Here is the code for the lovejoy L-050 inserts.

This code requires a 1/8" bit to be used.
The center of the insert is coordinates 0.0, 0.0 .
The code is in mm.
Max depth of cut is 12mm. (1/2" = 12.7mm)

I cut a set of curtain rod brackets for a friend, 22 in all. The bottom is to be routed with 3 small semicircles. The final paint finish was her job.

Made some adjustments to the inserts. code posted below.

Here is a pic of the two versions.There is a third version but its a little loose.

Here are the final ones i made, they fit very snug and no play in them, try it out and let me know, it is in inch's, 0.25 endmill, 0.5 stock.

[Jason Marsha]

I will try it and let you know.

What type of material are you using to cut the spiders?

I am using a cutting board which is medium density polyethelyne and this requires a little finishing sometimes.

DHPE 1/2" and a 1/8" carbide bit

I tried the spider file Joe posted but used a 1/4" bit instead of 1/8" (chair) , I must be working too hard .

Here are few pics of some work I am presently working on, a clock in the shape of a shield. This is a sample cut using plywood to give the client an idea of the expected results. The recessed square in the middle will hold a thin sheet of aluminum which will have a crest and some text in colour. My client can apparently print images onto the aluminum.

The wooden curtain rod supports are quite popular as well, a friend wants me to cut 60 for him.

Within the next week or so I should have a new router holder as well.

that looks pretty cool.

[Jason Marsha]

The design is 20"tall and 14" wide. Total time 32min at 40"min with the pocketing using most of that time.

[Jason Marsha]

Thanks Joe.

I almost forgot, I also got my little JCKlienbauer mill working. Here is a pic of the setup.
The motors are a little weak so I am topping out at 30"min rapids.

Well that batch of 60 curtain rod brackets was going fine through the cutting process until Mach3 kept on stopping due to a limit switch trigger. I thought it was a one off error until it happened one minute after restarting the program. I returned the machine to the origin (X0,Y0) switched the machine and the computer off.

A couple of hours later I returned to resume cutting but again the switch was triggered 5 minutes into the cut. I thought Mach 3 would indicate the switch being triggered but on testing it became apparent that once the switch is released the light on the diagnostic screen would return to its unlit state.

In order to ensure that a repeat did not occur I simply disabled all the switches until I can isolate the guilty switch. The other possibility is that one of the limit switch wires is frayed or broken internally and such a occurance would trigger an error.

I should have it solved by monday hopefully.

It could be noise on the lines. Try increasing the debounce, to maybe 2000 or even 5000 and see if that helps. Config>Logic
