RijK words all missing for arcline - SOLVED.

[rick2017]

Hi all.
I am trialling the available low cost CAM software before purchasing.
I quite like Qcad itself. I have trial version 3.17.1.0. I tested on win 10, 7 and XP.

Trialling the Cam output I ran into a problem right away with curved objects, (gears).
Mach3 (V2.63) objects to the G code every time/file with the message - RijK words all missing for arcline XXX. and refused to load.

Thinking it might be my dxf file I tried a simple 2 circle file, (attached, as is the generated g code)
Mach3 gives the error objection to line 12 in this

With other Cam software I have so far trialled, this and other curved files cut without objection by Mach3.

Is it something I am doing, something wrong, or a limitation of the trial version, (code generated whilst CAM and PRO are active).
I've searched the forum but find nothing relevant.

I can't see how to edit my original post but the Mach3 error code for the attached Gcode should read :-

RijK words all missing for arcline 12

Anybody?

Can you attach an NC file with arcs that works with your controller? Thanks.

Can you try to add a G01 before the G40?

Code: Select all

N130 G01 G40 X16.1414
...
N210 G01 G40 X30.1421 Y0.8579

If that works, the postprocessor can be adjusted easily as well.

Andrew thanks.

Yes, the addition of the 2 G01 commands made it load and run in the Mach3 simulation window.

Another file attached that works.

OK, thanks. This is a known requirement of the Mach3 controller.

Please use the "Mach3" configuration / postprocessor instead of the generic GCode configuration:

Andrew, thank you.

As I said in my OP I am trialling version 3.17.1 which does not contain the Mach3 post processor – (I did look at the post processing options before asking the question).

I note it has been added since and is available in V3.17.3.

As a hobbyist needing to count the cents I need to be sure it meets my needs. I find Qcad itself reasonably intuitive but want to make full use the Cam add on before buying.
