General Mach Discussion / Re: G31 probing via array macro.

« on: November 06, 2007, 05:15:59 PM »

Thanks Terry,

I am knee deep in pink foam shavings at the moment and may be through tomorrow. If I get tired after while I may hook the probe back up and give it another try.

Oh Stirling.............. You have made my day.

Terry thanks for the heads up. This is exactly what I need.

Now do you guys think we can bribe Art and Brian into adding this to the 3d plugin to set a boundry for 3d probing. This would cut so much excess time for me due the odd shapes I have to probe. Hey I'm not above begging either!

Mike

ps Stirling I haven't read the whole thread.....so how do I get this goodie?

Hey Terry,

I am on my way to the shop to test this out and will be back later to post some results.

Chip hopefully your quest is where this testing is headed. While it is nice to be able to do this in a macro, it would be so much nicer if all were included in the probe plugin. I hope you noticed my question to Terry about the possibility to use this as a means to set a profile that could then be digitized within the parameters picked up by the array macro. That almost sounds like what you are looking for as well.

Hi Terry,

I just got back from helping my son in law process some fresh venison. I'm tired and will now wait till morning to test the array code.

I kinda suspected you were into motors of some sort when I saw your post about cam grinder over on the yahoo group and now that I have seen the head porting post I know for sure you are. If I could show you the other project I am working on I bet it would get you going. Full size car body made from slices of foam 1.5" thick then glued together to make a plug. This thing is going to be nice.

Oh yeah I forgot, what kind of angle is needed to get a decent point file? Is the photo you posted earlier like you think I should set the body up with, and if so, are the polar array lines about what you think is needed?

Now come the really not understanding part. If the photo represents your optimum cpl for this guitar body, why wouldn't a symetrical polar array based on the therotical center of the body be a better solution? The reason I ask, is if you choose the center/1.5" from left side cpl it looks to me like you are going to have some point not be picked up due to the leg length no being long enough on the right half of the guitar?

Questions......questions?

Terry I thought I would add the last email you sent to me to include it in the thread and maybe it will help others follow along and you kindly lead me to 2d knowledge!





"Hi Mike, there is an interior and exterior Gcode file.  THe m1299 macro will work for both.
 
The best center start point is on the center line of the neck and about 1.5" in from the left hand edge of the body. I believe that will give you a 99%+  fill rate on points.
 
I have a polar line array printed on a sheet of transparent Mylar (24" dia)that I can overlay the drawing and work out the best approach and center start point.
 
You might want to make one for yourself to lay out over the parts to figure out for yourself if there is a better point. Just place it on top and look at the approaches on the lines and look for areas that the probe cannot reach traveling in a straight line.  (;-)
 
Do a couple of small objects first to get a feel for the process(;-) I would hate to know I helped to scratch a LES PAUL.
 
I did a 1" 6 sided Hex socket here inside and out, it was amazing. I then washed it thru Lcam to create a cut file with tool offsetts. Then cut another socket out just like the original even the square drive hole at the bottom of the socket.
 
(;-) TP"

Now I have a question  from the manual.

"4.  SafeZ:                 The safe Z height at which the probe can
                           travel.

5.  Probe Height:          The Z height of the probe cycle."

In setting these z heights are we staying in referenced dro readings or do we have to zero the dro's of do offsets and such? The reason I ask of course would be the long dialogue we had on the yahoo group about crashing my probe the last time.

If I follow the following sequence will I be ok?

1. reference machine and have dro's at 0. Mdi to my cpl and set my z axis to the "safe z height'?
2. run the exterior probe gcode, which will pull up a menu for me to set that is shown in the manual?
3. complete setup and run the code.

You ask me about calibrating my probe tip. Is this done in Mach or in the array probe set up?

Mike

Hi Jim,
That feature will probably come down the road a little bit. I'm mostly concerned in getting as accurate profile of this body as possible.


Terry,

Something is up with the email alerter. I got your private emails but nothing to tell me there had been any post to this thread. I have been knee....no...chest deep in a battle with my cam program today and I know it is probably a parameter I am not setting correctly, but that doesn't lessen the stress level any. You should have another private email from me now. I will try to get to the shop this afternoon and test this thing to see what I get. For safty I am going to use a block of foam for the test. Other than the one on the machine, I don't have any probe tips left!

Terry what file extension and I would rather not post this one on the web since it is for a customer. Email me at

You should know how to put it all together to make it work. I will then send the file directly to you.

Terry I keep thinking of all these things after I have hit the post button! Any chance you can be in Knoxville Tn the last full weeked in Feburary for a tentative Southeast US Mach convention? Poppabear (Scott) is heading it up. If it goes off, I have already comitted to give away a $1995 seat of Madcam which is a cam plugin for Rhino and hopefully by then I will also have a new cad/cam beta to let people try out? This would be a good time for you to teach about the probe plugin as well as demonstrate it.
