Hello, I do not have a lot of programing experience, and I have an issue with a program, for a Hardinge Conquest St225-B machine. I believe the program was created on Part Maker. The program works on the machine, but I cannot get the thing to repeat. It ends up pausing after the slotting cycle. It almost seems like there is an invisible M0 in the program. After this stop the program will part-off and start the program again. I have to make 1000 + parts and right now I'm pushing the Cycle Start button once per part. I included the problem area of code. I looked through the thing and could not figure out what is causing the problem. I would really appreciate if someone could tell me the problem or get me on the right path to fixing it. Thanks.

I dont know your machine specifically, but the M900 codes appear to be wait or mode codes. My quick google search shows that it has a dual path control. My guess is that you have a mismatching wait code in one of the programs (main or sub) or subprogram. Double check all your M900 codes, that they have a matching pair, are in the right sequence, and are not duplicated accidentally.

That's my guess.

Just to get it out of the way, you don't have optional stop turned on on the machine do you?

[Dichotomy]

I have repeat mode on, so that it runs through the whole program. It just stops at that area. I'll try adding in Sync codes right before the error occurs to try to prevent it from becoming out of sync.

[Benpen]

So, I understand where it looks like it stops, but your wait codes look fine. Usually the screen is a line or to ahead when it stops like that due to the way the nc buffers the code. Either it's stopping at the M1, which means you have another switch turned on other than repeat. Or it's getting stuck on g18 or m24. An m code (m24 or the wait codes) failure should alarm the machine out, but you are saying that it just sits and waits for you to hit start. And then runs ok. G18 is just a plane shift can't imagine why that would do it.

There is not error alarm message at all when it stops. I removed G19 M24; from H1 after the m905, because the machine would error here. The feed hold button would light up and the machine would stop. The programmer's manual says that the G19 selects the yz plane. I thought that because a B axis move was called up after the G19, that this is why the feed hold button would turn on. This error does not happen anymore but I thought it might have something to do with the issue now.

[Benpen]

So weird. Try moving the g18 after the m908 down to right after the t0505. See if that fixes it. Nothing else makes any sense. Put a () around that m1 right after the m908.

Figured it out. The M24 is not recognized by the hardinge machine. I replaced it with a M05 and if fixed the whole thing.
