Reading Arc move Errors

DOUG888 commented 8 years ago

It appears that UGS requires all incidence of I and J moves to be preceded by either a G01/G02 or G03. With programs like BobCadCam etc. the initial noting of the G01 (2 or 3) is not repeated every line but is only added after the incidence of a different G02/G03, this seems to cause an error and stops UGS.

see an example below N21 starts with a G02 which is reflected thru lines N22-N26 where it changes to N27 G01 then N28 G02 again. Where ever there is a missing G01/G02/G03 on an I J line there is an error and UGS stops.

I have run script where the G code is in front of every I J line and it work perfectly.

Can this be fixed to support different cam software. Thanks

This is part of the linux cnc gcode specification that GRBL implements: http://linuxcnc.org/docs/html/gcode/overview.html#_commands_and_machine_modes

If you have specific questions about why maybe try asking on the grbl github page.

DOUG888 commented 8 years ago

Hi Will..Thanks..checked the link out.

also

I ran the attached code on UGS and got the expected error, however I ran it on GRBL Controller 3.6.1 and also on JCNC without the error occurring.

This would indicate that the problem is in the sender rather than GRBL. My experience with Linux source code programming is minimal but maybe

inserting a flag to capture the last G code used in IJ instances would solve the problem.

??are you running a Linux machine to test or a Windows, I am running Windows7. Would it make a difference?

I am sending this direct to you as I don’t want to create discord on the forum and figure we can sort it

As always

Thanks

On the gcode controller options page do you have any commands filtered out? I'm wondering if you clicked "yes" to one of those "skip this command" errors:

I have now cleared all that out.

However I just noticed that Arc expander is un ticked as is Feed speed scaler, these are as per default settings.

Yes I saw your post. This is still puzzling to me, since I ran the same gcode you posted and didn't have a problem. Feed scaling and arc expanding are disabled by default so it looks like your filters are fine.

I finally remembered while typing out this response... I found a bug in the gcode processor on the 12th that causes this. I'm really hoping your copy of UGS is older than that!

If you speak regex:

Pattern GROUP_PATTERN = Pattern.compile("([GgMmSsTt].*?)(?=[GgMmSsTt]|$)");
Pattern GROUPPATTERN = Pattern.compile("(.?) ([GgMmSsTt]._?)(?=[GgMmSsTt]|$)");

The "command splitter" attempts to split up the different commands so that I can report errors more accurately (i.e. grbl would report an error for line "G21 G90 G61" but you wouldn't know which command was the problem). The green part was missing which caused all implicit commands to be removed!!!

Just ran one of the offending programs and noticed that the fault happened, as you said, after a G00 line, which does cancel the G02/G03 link.

This would be a POST weakness. NOT a UGS fault…….. :p (sorry about that)

So the solution Post I’ve put up is even more relevant than before as it is focused on the POST mod for my setup

Does your original file work with the current nightly build of UGS? Does it work with other gcode senders?

DOUG888 commented 8 years ago

No it still has problems with the latest Nightly version, Yes it does run under JCNC and GRBL Controller. It still appears to happen after a G00 command when the G02/G03 Arc is before the G00 and the arc code continues after. Code attached shows this...first error set is at N232-235..next set is at N289,291,292,294 then at N299-302 etc

Ok thanks for bearing with me. Maybe those other senders continue to send after an error.
