Qtplasmac Run From Line

I just updated my plasma to Qtplasmac.  Everything seems to be working fine except I am having trouble understanding the run from line command.

In the attached partial ngc file, If I try to start on line 420, It creates the rfl file, with the first line being the last move before the M05 (Which is a G02...).  When it tries to start on this line, Qtplasmac  gives me a radius calculation error because it has no real start position.  If I change this line before the M05, (which is an exit command from the plasma cut), to a G01 - it works since there is no radius calculation.  Is there any way to just start on the G00 command, or am I doing something wrong? 

Unfortunately, all my files contain an arc for an exit.  

I tried to run through this and see what I could see, with your partial cut file being a mess, it's hard for me to guess at where you are trying to start and what is going on. Can you post the actual cut file?

Also, what version of QtPlasmaC are you running? need the entire number in the window header.

Here are the complete files

It's because: shows up in every line.

I could modify the g-code filter to remove it, but honestly your Post Processor needs to be modified, there's a lot of stuff that needs cleaned up in your cut file. That, G1 lines with no XY movements associated, G00 being separated from the corresponding XY moves, etc.

I am attaching your file, with all of those Feed rates removed, except for one at the top. That will let you do RFL to show you that is in fact the issue.

You should take a look at the nc_files/plasma folder to see examples of what's expected. metric_wrench.ngc is a good starting place.

Thank you for taking the time to look at that.

I will clean that up.
