G-code error was created by allenwg2005
Hey folks!
Got a question.
Below are two gcode files of a .500 diameter circle, one with a lead-in and one without.
Neither file will load into LCNC.
Error= "Rijk words all missing for arc"
What's the fix for this?
Try and stay cool out there.
Thanks in advance for your help.

Your first G2 line only has an I term, then you have a lot of G2 lines without any I or J. I think the I and J need to be specified on every G2 line even if they are 0 or unchanged from the last line.

This might work better, you also had a bunch of problems with cutter comp and your lead-in size(s). You might also need to add a lead out.

Thanks Todd,
I didn't realize LCNC didn't recognize comp insertion with a zero move, most NC machines do.
The lead-in was just me trying dramatic things to see if it would help.
Thanks again, Allen

In order to arrive at the compensated position from the uncompensated position you need to move longer than the tool diameter. I can't imagine how a NC machine can do that without moving and still be in position at all times.

JT,
Thanks for the reply.
According to other CNC forums, a 0 comp isn't an issue with most machine controls, it's been asserted that this is a LinuxCNC "thing".
I'm no authority on any of this, it's just what I've been told.
Not that it's any big deal, any software will have it's proclivities.

Not disputing the "CNC" experts on other forums but my old DX-32 control and IIRC (I'm too lazy to look) my even older Anilam 1100M control require you to make a "approach" move into the compensated path. The DX-32 the "approach" move is the next line after G41/42 and must be equal to or larger than the tool diameter. So it is definitely not a LinuxCNC "thing".

I'll be honest I don't really use cutter comp. CAM takes care of all that for me. If I were coding by hand I would almost certainly use it alot. But I still think proper lead-ins and lead-outs are necessary on most if not all controls to get a proper cut (without gouges) when using cutter comp. Most controls may not require them, to run the code, but they still are needed to make a proper part. Maybe Linuxcnc is trying to be too clever in its attempts to save us from ourselves.

I'd rather it be clever when I'm being not so clever. It does make sense that the first move after G41/42 has to be at least big enough to get into the compensated position.

Speaking for myself, LCNC can have all the quirks it likes!
The fact that it's so flexible and can be adapted to so may different machines makes it worth every dime.
Oh that's right; it's completely free!
I'll put up with whatever “thing” it comes up with for the trade off on the price tag.
Thanks again guys, Allen
