General Mach Discussion / Re: Inaccurate Cut Dimensions Weirdness

« on: May 31, 2009, 08:35:05 AM »

Daniel,
There is a practical side to CNC. We would like to think that all involved with making a part is perfect.
Just hit the button and everything should come out just so. We loose sight of all the things that add
to not meeting some tolerance. Testing and knowing how things turn out using your machine along with different
machining conditions, applying that knowledge, is just a practical side that needs to be applied to the job.

If the combination always gives similar results, do the rough and add some tweaking to the finishing based on what you know.

General Mach Discussion / Re: Which CAD/CAM software for newbie

« on: May 31, 2009, 08:12:20 AM »

The Hobbiest price for Weber's "Synergy" is $89.95 and the trial period is 30 days. The 3D cam jumps to $1250.
Like all software there is a learning curve and i didn't find it too intuitive.The software is not restrictive in the sense that it's automated and and you can't do something. Talking to Weber, they made it just the opposite in that it's configurable and meant to be used however you want to use it. Lots of buttons, pulldowns which would be expected, because you got CAD, Mill, and lathe all wrapped up into one package. I just fooled with it for the lathe
and it actualy allows you choice, but, trying to figure out the logic will take some time. If you never fooled with other
software before and have no feel for what to look for you may be at a total loss.  If you try it, watch "carefully" the few tutorial videos  and try to get the logic of how the program works paying particular attention to screen prompts etc. I need to play with it more, but for the price and what you get, it may be worth some time to see if it's right for you.
To make software easy to use, restrictions and decisions are made for you, and you live them......on the other hand, if it's not restrictive, then you need to take care of all the details in order to use it.
Just my first impression of Synergy,
RICH

What Hood mentioned, namely actual cutting of the material to find a usable tool diameter, as compared to, measuring the end mill with v-anvil mic's and using those numbers in your code. Cutting with and without coolant and also direction has an affect. Just may add up to what your differences are in the end.

DaveA,
Could you post an example or some code, of what you are talking about. I took a look at my Smid book looking for some preferences in the interpretation but couldn't find anything specific. Just trying to learn something.
Thanks,

G-Code, CAD, and CAM discussions / Re: Need help with 4th axis continuous motion code

Hi All,
Just modified some verbage in the posts. Didn't care for girts when i lived on the other side of the Mason Dixon LINE and frankly don't like grits used in way said. We are above it.
SO KNOCK IT OFF OR THE WHOLE POST WILL GO!
Have fun.

TT350,
As stated before, a mill is not a lathe. A lot of lathes have runout greater than +-.0001".
Just because something shows a reading to four places dosn't mean that's the dimension you actually have.
Relative to what?
You may want review some info about part tolerances along with info on spindle and tool tolerances.
But conceptualy if all the rotating and movement going on was perfect along with a  proper surface finish you could achieve that true tolerance.  Any way, back to your question.

Used properly, a calibrated Intrimik, dial bore, or air gages  will directly measure  + - 1 or 2 tenths.  They are not cheap! Go / no go plug gage would  better as it will start to tell you if there is symetry.
LOL

Is your "RESET" flashing, if so go to config>ports&pins>input signals and enable the EStop ( click in box and you will get a green check ) assign it to port, maybe 1,  along with a pin you are not using and click Emulated.
If that dosen't do the trick please post our XML file.
Your Xml file can be found in the C:\MACH3 directory, ie; Mach3Mill and copy it and rename it  something like
rirhett and post it.

General Mach Discussion / Re: Problems threading on the lathe

« on: May 29, 2009, 07:13:10 AM »

pan...m,
  Good for you. My SS is also mounted inside the pc case.  Common grounding, case shields the SS, the cable from USB to SS
is short and also has a choke on it. Taking a moment to think now about what you eliminated to get results would be benificial. It could have been a one or combination of things.

Hmm,
Diagnostics in or out, it's your nickle, you didn't take a peek at the updated manual.
Anyway, it's a dynamic manual like the program. 
On to your next version.

Art or Chip,
Is this version for real threading or just simulation?
