I've been running Machinekit on a BBB for approximately a year now. I could
still benefit from a little more tuning, but over all it runs well. Most of
the program I have run have been rather simplistic either hand coded or done
with Inkscape. The have been a couple of hundred lines maximum. Yesterday I
tried to run "real" code generated by Fusion 360 with the EMC post proccessor.
Despite being relatively simple machining operation Fusion managed to generate
23k lines of code. Everything loads up fine, the visualization comes up,
however the actual machine blogs down to the point it is not functional. It
takes several minutes to zero each axis and the code will not run. There are no
errors it just will not run. I'm assuming it is to much for the limited
processing power of the BBB.
Anyone have a good rule of thumb about a good safe number of lines for BBB?
I run much larger programs than that for 3D printing, but you have to
disable the 3D preview for the BBB. Put the comment (AXIS,stop) at
the start of your ngc file, ie:
G21 ; set units to millimeters
(AXIS,stop)
...
Or use the preview block I built into Axis from your ini file
|[USER_COMMANDS] DISABLE_DISPLAY = YES |
