I have just discovered that PP and I think Linuxcnc treats M00 as a Pause rather than the traditional Program Stop. I have a lot of code where I program in an M00 to do things like move a clamp, redirect a coolant nozzle after a tool change etc etc. Run from here can be cumbersome. I machine a lot of castings and I use a lot of probing operations to pick up features with M00 in between them. Doing run from here after each one is going to be a huge hassle.

I'm kind of surprised this is how M00 is handled especially since it really isn't what I would call a standard way. Tormach's documentation even lists it as Program Stop but it really isn't. I'd be interested in hearing about any workarounds other than run from here.

Thanks
Derek

The correct use of M00 is Program stop (Which is just a Pause) Press start to continue.

M01 can be used also optional stop

...this is new to me.
M00 or MOO are two different statements. Must be the problem, but I would think a Format error would popup.

M00 is defined everywhere I can find as a program stop not pause. It is a stop in Mach3 and a stop in UCCNC. From what I read Fanuc is the same but I have no direct experience with Fanuc or any other commercial system. In Mach and UCCNC when you add M00 to the code the program stops running code at that point and allows jogging, spindle control work offset changes. Everything that a program stop, not pause allows you to do. When you push run agin it acts like whatever below it is fresh code and does whatever you have told it to do.

M00 is program stop. MOO is the sound a cow makes.

I agree that M00 is not just a pause. That would be feedhold . It is a true program stop when the program and ALL machines states are suspended and all aux functions like spindle and coolant, mist,et,etc are stopped. From that point you can jog away and do whatever. Then when you are ready to return to the program you move close to the restart point turn back ON the aux functions and press CycleStart. The machine will then move to the next line AFTER the m00 and resume the program. That is how the big boys play and it is the correct way for M00 M01 to work. It is VERY important to have a function so that you can stop inspect adjust replace and then return back to the program. RFH is not effective for this function as there are process you can have in the Gcode that RFH cannot interput correctly and WILL cause a crash

Just a thought , (;-) TP

It's a LinuxCNC thing, so probably not something Tormach is going to implement unless the LinuxCNC code changes

https://www.linuxcnc.org/docs/html/g...ml#mcode:m0-m1

M0 - pause a running program temporarily. LinuxCNC remains in the Auto Mode so MDI and other manual actions are not enabled. Pressing the resume button will restart the program at the following line.

M1 - pause a running program temporarily if the optional stop switch is on. LinuxCNC remains in the Auto Mode so MDI and other manual actions are not enabled. Pressing the resume button will restart the program at the following line.

Apparently it's been under discussion for many years

If you want to end the program with an M00, why not just put an M30 there?

I have to ask, the last dozen threads or so in this forum are a list of complaints you have about Pathpilot so why are you even using it if you feel that so much is wrong with it? I doubt Tormach is going to make any changes to suit how you want it to run.

As it reads it is only a Program stop, which is a Pause, in the program, It stops the axes, spindle, and turns off the coolant it only stops the Program running, which is correct, yes, we know what Hobby users do Mach3 made this easy as you could do all these crazy things.

Could you imagine this happening in the real CNC world, what a mess it would be.

HIya Mactec, I hate to be the one to let you know but pathpilot does NOT do it like the rest of the world does it. M00 in the real world is program stop not pause(feedhold) In M00 you should be able to stop the spindle and coolant and jog away to check something then press cyclestart and it returns to where it stopped and continues on. Haas calls it RSJC. Run stop jog continue.

Found this so it is how the software is for LinuxCNC

M0 - pause a running program temporarily. LinuxCNC remains in the Auto Mode so MDI and other manual actions are not enabled. Pressing the resume button will restart the program at the following line.

M1 - pause a running program temporarily if the optional stop switch is on. LinuxCNC remains in the Auto Mode so MDI and other manual actions are not enabled. Pressing the resume button will restart the program at the following line.

Note that LinuxCNC calls it also a Pause

I said that in my first Post if you care to read M0 is a Pause Just as I posted for LinuxCNC /Pathpilot

If you have used LinuxCNC you would know how M0 works

HIYA Mactec , Thats funny I use PP everyday for about 8-10 hrs how about you ?? How long did you use PP or Linuxcnc today ??

(;-) TP

[vmax549]

Hiya Footpedal ,

IF you were to use M30 that is a program END function that dumps the Que and dumps all the machine states and sends you back to the top of the Progam file. Ready for you to restart from Scratch .

Why COMPLAIN about PP ??? Would you sit on the front porch every day and let the dog pee on your leg OR perhaps voice your opinion on the subject and possibly get the situation changed. ????

... possible workaround is write each Tool as a Program then use Recent Files drop down menu to load file?

[popspipes]

I use a .25 tool for roughing and a finish op for that reason, it will complete the roughing op and stop and wait for a tool change, the rough tool is say #10 and the finish tool is #11, its the same tool but does two different ops. I also use it for a stop to clean chips etc. before restarting.

yes , on fanuc you can jog or do whatever it is you need to do once the machine comes to a stop at m0 or m1 . Some controls don't allow this which is a pita . I'd be ok with the stop as it is if I could at least do offset changes on pp

Nothing funny its fact, you only have to of used it to know how it work, I don't play with hobby machines.

And in a few clicks you can set the start line to wherever you want. Easy.

You've said several times you aren't using a Tormach machine, so in your example the dog is already peeing and you're sticking your leg under him. Maybe don't do that (ie, use a controller that already has the features you want).

[vmax549]

Hiya FootPetal. Most experienced operators know that is is not always possible to restart a program with RFH. This is a Tormach PathPilot control running a real CNC machine. As long as you sit there and say nothing that dog WILL still pee on your leg. (;-)

I offer constructive criticism so that Tormach and maybe others may learn something usefull to help their customers have a better Machining experience. What did you offer up today to help your CNC friends ??
