See 2nd post in thread for description of buggy behavior.
I'm cutting a circle and using using tangential mode to make sure my cutting head is aligned properly.
The problem I'm running into comes down to the fact that I only know how to flip the tangential bit - I have been unable to figure out a way to test it or say "turn on"/"turn off" and it sometimes get flipped without my knowledge. This leads to situations where I a piece of code winds up turning it off when I meant to turn it on.
I'm afraid I'm missing something here - is there some way to turn this feature on or off, rather than just toggling it? Alternatively, can someone suggest a way to test it in code so that I can determine whether or not it needs to be flipped?
Here's a snippet of the code I'm using
G1 X6.5 Y5
M1000
G4 P.1
M1020 (macro to set tangential bit)
G17 G2 X5 Y5 R.75
G2 X5 Y5 I1.5 J0
M1001
G4 P.4
For reasons that are entirely beyond me, the first G2 command uses tangential perfectly, but the second doesn't. The first M1020 command brings the knife direction indicator up onto the toolpath screen, and the pointer (and the actual knife) move perfectly. When the 2nd G2 move starts, the direction indicator stays up, but it no longer moves.
I'm stumped. Any help would be appreciated.
Thanks,
Matt
