still having trouble with Arc Radius and cutter radius
« on: December 29, 2006, 10:45:34 AM »
this is a rework of the post "Arc Radius and cutter radius" from about a week ago

LC - 2.0.31
Mach3 2.0.29

I need some help.  I seem to be the only one have this problems cause no one else jumped on my original post..

I had some time to work on my project this morning. I loaded up my files and started running a simulation before cutting.   I cannot get tool compensation to work.( the cutter appears over the part outline)  While watching the run on the “program run “ screen,  the tool data shows the correct tool number and assigned diameters after each tool change.  I’ve reloaded  (same ver.) Mach 3 this morning but the problem does not go away. 

I had this poroblem in my original post but is disappeared ???

Any suggestions – it’s gotta be something I’m not doing right.

Lazycam suggestion.
When I repeated the simulation a second time I was left with the last tool change I made in the last run.  You might want to add a tools change at the beginning of the g-code program  (first cut) to insure the correct starting tool is loaded.

This would not let me post my dxf and gcode files (said they had already been uploaded once and kicked out the post).  See Arc Radius and cutter radius if interested.

Rename your files something else and try to repost them. I wish I could help more. I have not used LC or Cutter comp.

;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

enter the tool dia that you would like to use into the Dia dro on the settings page. You also need to have the dia set for the right tool number... Look up the G41/G42 and tool table for more info.

Thanks

Brian - I already had tool numbers and diameters loaded into the setting page.
when i run the program, tooling data appears correctly (number and dia) on the "program run" screen.
they also update correctly at tool changes.

that the problem - it should have worked  ???

Post an example Gcode file and I will see if we can get you running

ok - I found the problem.  LC did not put the g41 /g42 into the Gcode file.
i don't know why but downloaded the new stuff this morning, rebuilt the part and it runs fine.

I've included the old gcode if your interested.
as you can see tools changes are in there just no offfset calls

almost got it
one more problem with canned drill cycle.
I've now got this error message
" R less than Z in cycle in xy plane on line #8"
here is the actula line of code
 
N45 G81  X0.4771  Y1.1648  Z0.5000  R0.0000  F3.00

another suggestion:
insteead of quoting the actual line number it would be nice to know the "N line number" (N55)
might help on larger programs.


as always thanks for being so patient with all us newbee's

Can't do that :( in notepad you can tell it to goto a line number and that will be the same as thing numbering in Mach3.
I never use line numbers in my programs, I think that they are useless and only make the program bigger ;)

that is just me...

Got it - now i understand why it's that way.
I was looking at it as debuggin on the m3 screen not in notepad.
thanks as always
