Can anyone answer this query please?    I have no trouble using the text wizard when running mach 2 but when I change to mach 3 all I get is loads of lines of  G01 x50 y50 I50 J50 and error messages saying  "zero radius arc on line  ***********  Everything else seems to work ok.  Thanks in advance.  Is there a more comprehensive Text wizard available anywhere?
Jacko

Could you please tell us the settings that you are using?

Hi,
    I guess you mean settings within the wizard.  I type "ben"-  letter height 40 - seperation 100 - feed rate 300 - metric units - start point x50 y 50 - italic font - When it loads the g code there are 54 lines which most are " G01 x50 y 50 I 50 J50" and this "zero radius arc line 11" error message.
I loaded mach 4 on my office pc ( not the machine pc ) the other night just to have a look at lazy cam and the same thing happened when I tried it out.  Very odd.  As I said I have no trouble when using mach 2.

Are you installing from the same download on alll computers? maybe it is corrupt, might even be a corrupt write file that is not getting over written with the new install (dont know if thats possible) but you could try deleting the write wizard folder then reinstalling Mach again and seeing if it works.
Hood

Hi Hood,
            You are a good lad trying to help out.  I uninstalled mach 3 ( which doesnt uninstall the "addon" folder and so I deleted that manually and then downloaded mach 3 again .  I still get the same results.  I can use other wizards like "cut circle" - "cut arc" etc but the "write wizard" keeps giving me the same results as described before. Who said computers were easy!!!!
Jacko

Strange, hope you find the answer, it will probably be something insignificant but finding it will be a pain.

I have been wondering, if when i use the text wizard the IJ mode should be set to "incremental" instead of "absolute" in the "state" dialogue box.  When i change it "incremental mode" and run the text wizard I still have the same problem.  When i then check the mode in the "state" box it has changed itself back to absolute.  Why is that then?
Jacko

I found last week that if you create the code, then save it, exit and restart Mach the file comes out as big circles - it seems to be something that is initialised by the wizard, but is then reset when you start Mach - i.e. something is changed by the wizard and not referenced in the G-code.

Cheers

This is an arc error Add a G90.1 and you should be okay
