The only thing Ive noticed and it might be something on my end but it doesn't allow rev to the last M3 command it only allowed a certain number of lines. I was doing an outside cut arc went out and decided well for sheets N grins lemme run this bad boy all the way back and nope.
It seems that I was mistaken, it appears that the reverse queue is limited to between 200~220 (I am guessing segments) so if the M3 is more than about 200 segments away then it won't be reached.
From tcq.c:
Code:
#define TCQ_REVERSE_MARGIN 200
* sets up a margin at the end of the queue, to reduce effects of race conditions
*/
#define TC_QUEUE_MARGIN (TCQ_REVERSE_MARGIN+20)
For fun I did try 1000 and it had no ill effect that I could see...
If it is necessary to go further back than what the REV button allows then you would need to run from line:
