single block problems
« on: November 18, 2006, 10:36:32 PM »

I've been having problems when running a program, putting it into single block near the end of a contour, it has taken off. It did it with mach 2, now I'm running mach 3 v1.9.081.
Heres the program:

O0001(11-18)
 
(T1 =  .25 ENDMILL 2FL H1 , D1 )
 
N1
T1 M06 ( TOOL - 1  .25 ENDMILL 2FL   )
M01 (PUT T1 IN SPINDLE)
M08 G04 P1000
G54 G0 G90 X0. Y0. S6000 M03
(WATCH OFFSET ON OFF)
G43 H1 Z.1
G1 Z-.1 F8.
G41 D1 X-.011 Y-.0064
X.0127 Y-.0475
G3 X.19 Y0. I.0823 J.0475
X-.19 I-.19 J0.
X.19 I.19 J0.
X.0127 Y.0475 I-.095 J0.
G1 X-.011 Y.0064
G40 X0. Y0.
Z-.2
G41 D1 X-.011 Y-.0064
X.0127 Y-.0475
G3 X.19 Y0. I.0823 J.0475
X-.19 I-.19 J0.
X.19 I.19 J0. X.0127 Y.0475 I-.095 J0. **
G1 X-.011 Y.0064
G40 X0. Y0.
G0 Z.1 M09
M05
M30

It took off in the line ending with **
I had run it twice in single block mode and it worked fine. When I cut metal, it took off, see picture. After that happened, I was unable to recreate the problem.
What can be happening here? I've scrapped several parts by this happening. It's always an arc at the end of a contour when in single block. I like to put it into single block at the end of a contour when running for the first time to make sure of the retract, etc.

There was a bug with single block and it was fixed in the 2.00 Rev

Please update

I updated and have a couple of questions.
First my coolant no longer works. The LED comes on but the solenoid won't fire. The only time coolant comes on is if I press RESET. Next, why did it reset my hotkey settings?
Finally I can't press single block when in cycle as I like to when near the end of a cut to check retract etc. Is that the way it should work

 ???
Confused

For the single block bit, try hitting feedhold then single block, that might work. I never use single block and dont have it on my screenset so cant say for sure.

Hi Mark,
   No, that is not how it should work. While code is running, I place in single block. It does stop at the end of the line I hit it on. But it jumps to the next line. On cycle start again the two lines are now a single move. If z is moving, I hit single block, it stops at end of line. Next line of code is a move in the x. I hit start, now the z and x are moving at the same time. This should not happen. Single block should simply pause the running at the end of a line of code. When you hit start again it should start back running as if single block was never hit. I think we gots bugs. ;D This is a problem.

I simply cannot put it in single block while in cycle. I get a "No singlestep in G41/G42 program" error. If I hit feed hold, I get the same error if I try then too.
At least before, I could get single block. Occasionally it would take off though, see first post

So, it is saying no single block option while in cutter comp.? I wish I knew, I don't use cutter comp. My cam package puts the cutter where it needs to be based on tool diam.

Mine does the same. I just use cutter comp to adjust size. I have my cam system to default to comp on.
