E Word with no G76 was created by lenarlwong
I use Slic3r to generate G-codes which I run in Linuxcnc to 3D print. Whenever I set the z retract to 0.1mm, I receive this error when running the Gcodes in Linuxcnc. If I remove the Z retract the error goes away. I have not tried other values for the Z retract. Has anyone seen this or have any suggestions?

Hi
Nothing attached.
Going by your title, the interpreter is erroring because it has encountered the letter E and G76 is the only code that uses it.
Put the code into a decent linux terminal text editor and look for spurious charactors.
If you can't find anything, rename to a txt extension and attach

Yes, in line 32, there is an E command issued. I only see this when I add a Z retract

Hi
Well that is your problem. I am not familiar with slic3r, so have no idea why it is producing moves for a non existent axis.
You could just use a script to remove all instances, but the answer really is to go into the settings for slic3r and find where this is coming from and change it
regards

Hi again,
I decided I had better get familiar with slic3r, as queries involving it are likely to increase as 3D printing becomes more popular
(not that I have one, so it is all virtual familiarity)
I set up a default config (accepted all default settings in the configuration wizard) and loaded this simple stl file which describes a spanner.
(remove the .txt suffix)
From this I generated gcode for Linuxcnc
Note no E axis moves, just XYZ and A, which I take to be the extruder moves.
I have commented out the M codes and it runs in a 9axis sim
All tends to suggest that something is wrong in your setup, looks pretty certain that the
G1 E0.00000 F1800.000 line
should be
G1 A0.00000 F1800.000
Run this stl file through your copy of slic3r, if you still produce E axis moves and cannot find the source, you will have to attach the slic3r config you are using
regards

If I use the printer settings as a Reprap, all of the extruder moves show up as E. If I choose Mach3/EMC, all extruder moves show up as A. But if I add a Z lift, for some reason, E starts to show up again, I think only for the lifts. Here is my config file.

Hi
Your ini file has the line
You might want to try changing that.
I cannot replicate your problem, with the stl file I am using, even if I set Z axis to lift I don't get any E 'axis' moves.
If changing the E to A in the ini file does not work, the best solution I have at present is
sed '/E/d' input.ngc > output.ngc
That will remove any line containing an uppercase E
(Just make sure you do not use one in any comments, or that line will be deleted too)
regards
