here is the file with holes and outside cuts all set to 45. I select one of the outside lines and click run from LINE and generate code so now only visible is 2 lines of the outside cut. It still gives the torch speed as 100.2 I also included the Run From file which is just 2 or 3 outside lines of the part. Maybe something is obvious here? But I did what you said to make all speeds 45.

i thought this was interesting issue. i use sheetcam as well can you share your dxf file and let me cam it out it see the difference.
a issue i see you have your plunge rate set to low. sheetcam defaults at just under 4 inches a minute. i use 100 it need to be at least 60. you may be losing arc and having to run from line because of this.
i would also address the issue of why you need to do restarts so often.
i believe the issue might be that firecontrol is reverting to the feed rate on the z axis ihs cycle which is 100…
i am running the latest version if firecontrol. i turned off the thc and it ran right. i did a run from line on the outside it pulled the feed rate of the z axis. this is probably a firecontrol issue.
I have tried to plunge speed at 50 with no change. I have also modified the G code to change that 100 Z retract speed to 50 and it had no effect on the problem of the torch speed being 100.2.
this isn’t the cause of the issue. it can cause issues of the torch not staying on though.
I don’t have a problem with the torch staying on. I have a lot of quarter inch steel that has random holes in it that are 3/8 inch in diameter and occasionally it’s difficult to avoid them and so the torch shuts off over a hole however I don’t have any concerns with cutting, but I do have to be able to cut from line often for different reasons for example, if cutting apart, the nozzle starts going bad, I can stop and replace the nozzle and continue where it left off and avoid wasting the material and time
dont get caught up on the issue of someone making suggestions they randomly see. i am not aware of anyone using that slow of a speed consistently. it is something you may have issues with later.
Yes I have started changing the plunge speed on new files, this is an old file I posted for reference to the problem that still has the slow speeds.
ok that is great
i just opened a old file of mine to try to mimic it. it ran as it should.
can you post your dxf so i can try to cam it out? that way we can see if it will do the same thing.
I can post the DXF shortly when I’m back at my computer. However, I just had the realization that if the original file runs great, but the new file run from line that is being generated from fire control has the problem, then the problem should be obvious somewhere in the G code… I have posted earlier and original file and my edited file. I need to re-examine those because that’s where the problem is. I wonder if I need to update the post processor in fire control if there is such an external post processor.
it is a fire control issue because fire control regenterated the codes.
your run from line code is programed at 100. fire control must have pulled speed from ihs cycle.
it does it with your file you shared but not any of mine.
send me the dxf when you can i will fix a file for you to test.
This is a dxf file. Thanks for the tips!

give this a try pierce delay is one second, feed at 45. i also put it all in one layer.

you can turn thc off and the plasma off and run the file without wasting material.
As an experiment I took the run from line code and went through and changed ALL values after F to 45. And it runs at 45. The 100 is coming from the post processor as I don’t have a 100 anywhere in my settings in sheetcam so it must be a default Z retract speed (up) built in the post processor. I can’t find a place to change it. At least now I have a way to solve this issue. Just open every Run from file and find all F values and set to 45. Somehow the original complete file works fine and it had F100 all over it. But the run from line is doing something I can’t make sense of. Run from loop works good.
Thanks for all the suggestions everyone!
I’ll check out the file you made to see what I need to improve.
i took your file and ran from line and it pulled speed from the ihs cycle. i made this file and did a run from line and it worked as it should…
this one works for you i will go with the idea of it has to do with the separate layers and speeds you used.
