Help with novamill and CAM gcode

[zlittell]

Hello my name is Zack. I am a student and our university has a denford novamill that no one has used in years. It has a denstep controller and the V2 milling software. I am wondering what post processor I can use to output gcode from featurecam to work in the VR milling software.

This should be possible am I correct? I see a lot of people doing conversions to mach3 as their control software what benefit does this have? Just the ability of a more attainable newer software?

I have tried the fanuc m0 post processor to no avail so I am wondering if anyone can help me out.

Example gcode using the Fanuc 0M post processor.
errors on 4 line because of too many codes on a single line
then every so often wants file 9099.fnc or 1011.fnc to be in the same folder and i have no clue what this file even is.
it also likes to complain about bad arc end points which i am just going to assume is because i have the settings in the screen shot wrong.

Code: Select all

I would really love to use this machine but it needs to accept gcode created from my inventor parts.

Also can anyone recommend any readings on the basics of CNCing. Such as setting up tool offsets and how to set up the reference point and stuff.

Someone has asked about featureCAM here:
viewtopic.php?f=16&t=1867

Maybe worth PM-ing them to see if they ever got one from DelCAM ?

You can point Delcam them to this if they'll create a post for you, or at least tell you which of the standard ones is nearest:
viewtopic.php?f=16&t=1370

As for help, start with the Help menu in VR Milling v2...it will be worth downloading the latest version from here:
https://website.denford.ltd.uk/index.php ... -downloads
You could open the .zip file and just view the help files eg, Mill.hlp

I PMd the OP from the other topic you linked the other night and am still waiting on a reply. I currently have no maintenance agreement with Delcam so asking for the post processor is not possible.

Maybe I can convince them to do it since I am a student but I doubt that.

Some things to try:
1. Make sure the output is metric with 3 decimal places (eg 25.400)
2. Disable macros - this should get rid of the errors where it's looking for program 9099.fnc
3. Definately turn off cutter comp - let the CAM output compensate for cutter diameter as VR Milling 2 will more than likely not do it the same as intended.

If you are then only left with errors about too many g-codes, then you may have to live with that, just edit the program and insert a new line between the list of codes...
