If you check out either the handibot or 100kSchools.org blog, you can see another setup for a handibot jig. For that setup, I created a jig that will hold a blank that is ready to be VCarved. I then created an .sbp file that will move the blank out from under handibot
and allow me to change the blank. The code for that file, with comments, is posted below:
'Moves jig for hex blanks out from under the handibot
'an apostrophe in front of a line is a comment for the user and will be ignored by the ShopBot software
'unless there is a pause after it...then the comment will be displayed on screen
'and the software will pause until the user hits the "enter" or OK
JH 'Jog Home
'remove back pegs
pause
m2,3,8 'Move 2 axes to the location 3 in the X axis and 8 in the Y axis
mz,-.05 'Move the Z axis to -.05 below the surface of the material
'remove front pegs
pause
my, 0 'Move the Y axis to 0
'replace the blank
pause
my,8 'Move the Y axis to 8
'replace front pegs
pause
JH
'replace back pegs
Pause
You can copy the entire code, open up the ShopBot software (preview or move/cut mode), choose FE to edit a file, then new for a new file, and paste into the file. Give it a name (I chose something snappy like: replace blank for handibot jig) and save it in a place where you know where it is. Run it in preview to get a feel for how it will work.
