MCX5 4ax post issue?

[johnh]

Hi all,

I've been playing around with our Hurco VM10i which has a 4th axis (A) installed. My issue is that I'm trying to get a part that has a thread type feature on it to run. When I output the code it looks like it has continuous X and A motion but the machine reads each line and brakes/unbrakes the 4th on every single move. I have no M codes active in the program that would force this. I can command X and A at the same time (IE: X1.250 A90. F25.) and the x and A move together, but not when it reads my code. Am I looking at a post issue or machine issue? I'm still getting into the 4th axis programming stuff so I'm not sure which way to turn on this. I've had some help from other guys and they have been able to get me to the point of gettnig the program right and now it's on the code. It would seem that Hurco tech support is rather slow on help so I'm hoping someone in here might have an answer for me, or at least point me down the right road. Thanks in advance!

Usually when doing full fourth stuff you will need to output some kind of rotary unlock command, then when the full fourth move is complete do a rotary lock command, this is usually a machine specific M code.

 

If you don't have them there the machine will still run however it will stop at each move as it locks and unlocks..

 

I did a quick search online and found this someone saying for a Hurco the unlock code is M33, lock code is M32

 

For starters I would put that in your code manually .. ie unlock before you start cutting full fourth and lock again after your done..

 

Assuming that works you could modify or else have your post modified to output the codes for you.. the mpmaster post has a setting for this something like unlock_codes or something..
