I’m pretty sure he is having the same issue that several others have had with the combination of Fusion 360 and the Titanium 45 plasma cutter. The torch stays on too long after the command to shut off and continues to cut for a short time on the rapid to the next cut loop.
I don’t know that Fusion is part of the problem, but I’ve only seen people have this problem with their Titanium 45 when using Fusion. I haven’t seen any report of this issue from Sheetcam users.
No doubt the titanium has some manufacturing/ tuning inconsistencies that makes their units not perform the same one to another.
it does seem that way? I wonder if we could generate a test piece of code through fusion and sheetCAM with the same parameters then compare them to see if there is any differences.
Is adding a “Pause at the end of cut” in sheetCAM the work around for a titanium with a lazy OFF.
I’ve post processed a file through Sheetcam for one of the people having this problem and it ran with no issue, but I have a .5 second pause after each cut in my Sheetcam operations. I haven’t tried it without the pause.
I looked at the code for the case that I was trying to help with and didn’t see anything that should cause the torch to shut off late. The torch off commands were in the right location, but the torch was clearly still on when it started to move to the next cut loop.
I have to wonder if it isn’t the torch shutting off late, but Fusion adding a movement before the torch off command. Maybe something like that odd “pierce clearance” thing that Fusion has that seems to be a tool offset holdover from milling operations.
Since Rat is not having this problem with the Plasmadyne torch, I think we have to consider the possibility that it could be the torch. I don’t know enough about the machines and torches to posit a theory on that.
I would agree with TinWhisperer it would have to be something like a relay. It’s only a .5 second or less issue you wouldn’t notice if it wasn’t cutting at 100+ IPM.
There isn’t anything in the torch mechanically that would cause it.
I never had a divot problem with the titanium 45, but I did increase the internal air pressure to torch, because when I first got it set up, I would get a random misfire and divots. I increased internal torch air pressure and never had any issues ever since. I am using the plasmadyn x45 machine torch with Hypertherm consumables with great sucess.
