Tom,
I noticed that Mach3 has a 'Run From Here' command - I assume that refers to a line of Gcode.
Can you add that to KMotionCNC?
It would be quite helpful for debugging things.
 
Thanks,
Michael Rosenfield

Michael,

Keep in mind, it does NOT work 100% reliably in Mach3, and is a frequent source of trouble for many users. Many/most Mach3 users have learned the hard way to instead use SetNextLine, then manually ensure all necessary modals are set properly, the spindle is on, etc. before resuming program execution.

Ray L.

Ray,
Excellent points!
However, Kmotioncnc currently can only start from the beginning of a program - at least, I haven't figured out anything different.

Hi Michael,
 
If you Right-Mouse-Click in the GCode Window there is a "Set Next Statement" option.  But it is totally up to you to make sure the next and following statement(s) makes sense.  For example if the last thing executed was a G2 arc and you move the instruction pointer to the middle of some xy statements that follow a G1 then the result wouldn't make any sense, generate an error, or a crash. 
 
There are about an infinite number of ways that things would go wrong, wrong tool loaded, wrong fixture offset, wrong radius comp, wrong units, unspecified axis, wrong plane, jumping into the middle of a subroutine, spindle off, variables with wrong values, etc etc etc...
 
In some cases we might be able to search backwards and figure out if things are reasonable or not, but that doesn't often work.  We are open for suggestions in this area but we don't want to do things that will be too complex and unpredictable.
 
Regards
TK

Tom,

In Mach3, RunFromHere does a simulation of all G-code up to the selected point, to ensure all modals are properly set. It will also do a "preparatory move" to the correct current position so the program, can resume, or begin, execution from the selected point. However, as I indicated, it is far from fool-proof.

Aha! Didn't think to right ckick!
Yes,  I know that this is a very tricky thing to do, and I have no good ideas about how to make it less so.
I would use this only for debugging; after trying some things, I resolved to repost the whole program to make changes.
Thanks,
Tom
