Kipware M Bad Character

[wbleeker]

Is anyone using Kipware M? I wrote a simple facing and pocketing program with
it, posted the code to Mach3 which all went fine, then when I hit cycle start I got the message "bad character in line 1" I don't know enough about G code (yet) to know what is wrong, I tried to copy the code into here but it didn't work?

Got it in here !

At least one problem I see here is you have comment text that is not enclosed in parenthesis -- see red highlight. Also you have two lines - see green highlight - that appear to be line numbers -- but none of the other lines are numbered. I would delete them.

As to why this might be happening - I don't use Kipware but I assume you have some kind of entry for the machine you are targeting - make sure that is selected correctly.

Thanks for that Jeff, the bit about the comments came to mind while I was thinking about the problem, I also sent the code to Kipware and they told me that the + symbol shouldn't be in the code too? I just don't know how it got there, the software wrote the code I just filled in the boxes. Another thing I am not sure about,I have Kipware set to Metric and put Metric dimensions in the boxes, should I see G21 in the code somewhere?
Will
I won't get a chance to actually run the code for a couple of days

I guess technically the G21 is optional assuming your machine controller is set to metric. However, good practice is to always have a have a safety block at the beginning of your gcode to set/reset your controller to a known state. A G21 would be part of that safety block. Do a search on gcode safety block and you will see there are typically 9 or 10 items in the typical safety block.
