Representing print area limits in Axon (for RapMan Twin)

Limits

One of the users on the BfB Forum was enquiring if it was possible to have a different print bed (his own design) visible on the main page of Axon.... well this got me thinking about the "Warning -out of print area" message that axon displays if you move an object around on the bed.... the warning isn't strictly correct. So I've modified the file that displays the print bed to give a visual warning…. Great for helping students to visualise where they can place their objects on the print bed.

So,

If using ONLY extruder 1 you can use the area from near the left edge of the bed to the line marked "Ext 1 Limit"

If using ONLY extruder 2 you can use the area from near the right edge of the bed to the line marked "Ext 2 Limit"

You would need to use the extruder mapping functions in the firmware to do the above.

If using BOTH extruders you can only use the area BETWEEN "Ext 1 Limit" and "Ext 2 Limit".... if using the BfB2 Z0.xx ABSPLA profiles (for example if using ext 1 for object and ext 2 for support materials)

To use this file browse to the Axon install folder ( the default is C:\Bfb Software\Skeinforge ) and rename the file plate.stl to something like plate.old - then copy the new file plate.stl into this folder (then you can always go back to the original if necessary).... the file is attached at the bottom of this post.

Note.... The limits represented by the lines should be ok but it is best to stay on the "safe" side of these lines to prevent the carriage crunching into the framework.

Note 2.... Apart from loading into Axon to see if it works I have not tested to see if it upsets the z height or any similar nasties... so use it at your own risk and don't blame me if..... etc.
