RE: Backplotter not working with BDI

[Ethan Vos <ethan-at-forward.ca>]

One thing I noticed that the version of backplotter that comes with the BDI 
(view, backplot) will not work if you start it while a program is running. 
You have to open the backplot first, or rerun the program once the 
backplotter is open.

Check the scaling factors. I think the default is 40 which worked for me on 
a part that was in the 3" range.

Hi everyone,

I can't seem to get the backplotter, tkbackplot.tcl, to work with the
BDI installed version of EMC.  All I get is a small window, about 2
inches square, in the upper right corner of the screen.  This window has
a white background and nothing else displayed.

The file tkbackplot exists in the plat/linux_2_2_18/bin and tcl/scripts/
directories, it has execute permission but does not appear to be
working,

There are no error messages displayed and tkemc continues merrily on
it's way processing what ever g-code is fed to it just as if you had
never asked for the backplotter to be active.

Any help will be appreciated.

Thanks in advance
