continuous operation
continuous operation
As the heading goes and again this probably has been covered before, so please let me appologise in advance, how do you get continuous operation with nested parts and different operations. Please let me explain. If I cut one part that had two operations (marking and then plasma cutting) I have 'clicked' keep parts together, the marking is done then we then have to press 'run' on Mach3 to continue to finish the part. This is quite fine, however if we have 40 items for example we have to stand at the computer and when one part is completed, the plasma will go the the next part mark then stop and wait for the 'run' button to be pressed again. Especially if all is working perfectly this is anoying and I could be doing something else. I need to 'keep parts together' as plate can move, then the marking won't line up with the cut part. I have done large jobs (6100mm by 1830mm) alli sheet and have done all the marking then the cutting, but would like to do the 'keep parts together' process. Any help would be very much appreciated. Thankyou
Re: continuous operation
What post are you using? Check the ontoolchange function. There is most likely code for the pause in there since it happens when you go from marking to cutting. See what code line it stops at, then search for that code in the post and comment it out.

I am using a CandCNC post. DTHC-HTY-TAP_Softpierce+Marker=rev12D
Re: continuous operation
I think there is a line right at the top that says Pause to check settings. You should be able to change that setting and get rid of the pauses. I think...

Re: continuous operation
Yes. In SheetCam go to Options->machine->post processor and click on the 'Edit post' button. On about line 12 you should see something like this:
Change it to:
Code: Select all
warnings = true -- set this to false to turn off the Check Parameters warnings on a toolchange
Code: Select all
warnings = false -- set this to false to turn off the Check Parameters warnings on a toolchange
Re: continuous operation
Gentelmen thankyou for your replies. I was hoping that there would be something that you can do in Mach3 or the computer running the G code. Ideally I would like to know if all is operating as it should then you can walk away (not too far) and let it go. At the moment I like to the pause at the tool change it is easier for me to recover from any issues when cutting. I may just need to get my head around this to be confortable. Thankyou very much, I now know that there is a way.
Re: continuous operation
You could get creative in Mach and make a macro that looks at the state of an LED, and pauses code if the LED is on. You would need to add a button to toggle the LED. Then just substitute the macro call where the original pauses are in the post.
This would allow you to decide if you want the pauses or not while the code is running.

Re: continuous operation
Good afternoon, that sounds wonderfull, however I am not that smart Lots of things are possible when you know how, I am an old dog now and very hard to learn new stuff, in fact hard to learn anything at all
Re: continuous operation
Post a picture of your mach screen. I'm not sure what vintage of CandCNC table you have. If it's the same as mine, I'll poke around when I have some time and see what I can come up with.

Re: continuous operation
Edit your post. At around line 677 you shoudl see this:
Change it to:
Now in Mach you should have an optional stop button. If optional stop is on, it will pause. If optional stop is off it won't pause.
Code: Select all
post.Text (" M00\n")
Code: Select all
post.Text (" M01\n")
Re: continuous operation
I don't think the CandCnc screen set has that button. At least mine doesn't.

Ah. That's a shame.
Re: continuous operation
Well good morning gentlemen, my version is 2013 and Mach3 has a stop button. Now I have tried to resize my screen shot photo of Mach3 but don't know how to as yet, however My Mach3 screen does have a 'stop' button. The 'stop' button is in the bottom right hand side of the screen, where the green run, tanny feed hold, just slightly above and to the right of the 'RESET' button. I will have a look into the post at the line that you have suggested Les and see what I can make of it. I will report back. From my assumption, Les, I should be able to toggle the 'STOP' button on the screen for the pause. Now is there any other problems that this may cause. I very rarely ever hit the stop button, only if I have a trip with the plasma torch or there is a problem with the consumables, that need changing mid cut, again rare.
Re: continuous operation
That STOP button just stops everything. There must be another button called optional stop that ignores the m1 command if it is toggled. I'm positive it's not the normal stop button.
Re: continuous operation
If your table is a 2013 then it's probably the same screenset as mine. I'll take a look and see if I can add the button for you.
