» Topic: Missing Feed codes
- April 3, 2014 at 12:01 pm #17467
I’m helping a friend and have a problem I can’t figure out. The CAM output was fine until he selected “Reset to factory default” somewhere. The contouring output was using “R” values instead of I,J,K. I have found where this was selected and got it back to the correct contouring output. However, no F code is being output in the NC code. I have looked for some setting that may be incorrect, but can’t find anything. We’re using the same Postprocessor that we used in the past and F codes use to be output. Any ideas on what could be the problem?April 21, 2014 at 2:20 pm #17808
Is this for lathe or Mill. Usually, the issue is caused by not defining a feed in the operation. Make sure a feed rate is defined, if it is set to 0, then define a number and it should work correctly.April 22, 2014 at 9:58 am #17861
Thanks for your reply Sean! I’m programming for a mill. When generating the gcode, there is a screen where you specify the cut depth, depth per pass and feed rate (plunge and cut). I have feed rates specified, but there are no F codse in the gcode output. The curious thing is that they were output in the past. Like I stated in my original post, my friend was having problems of some sort and selected a “Rest to Factory Defaults” option somewhere (he can’t remember exactly where) and I’m guessing that this is somehow at the heart of the problem.April 22, 2014 at 1:12 pm #17863
Please provide the part file and post processor.April 28, 2014 at 5:58 am #17957
Thanks for kick-starting my brain. When you mentioned sending you the postprocessor, it hit me. I had been going under the assumption that we were using the same postprocessor that we had always been using, but, when my buddy had clicked on the “Reset to Factory Defaults”, BobCAD had changed the location where it was looking for postprocessor files. There was one there that had the same name, but it wasn’t the one we had previously been using. Once I pointed back to our old post, everything was working fine
Thanks for your help!!!!
