Long ago when the tutorial was first written that was not possible. Subsequent releases added support for full 3D with the exception of undercuts.

I get an error code when I click on the link.

When looking at the archive link that Randall posted you'll notice big white blocks that say "Shockwave Flash" no longer supported. Those videos can be found on YouTube at his channel using the following link.

Re: Rotary G code Post by Phil » Sun Jan 21, 2024 7:05 pm

Here is my first successful attempt at writing SBP code. This is for indexing four flutes on a 4" dia. x 15" long cylinder. I copied the first part from a file created by the Aspire gadget. The rest of the code moves the router from 1" to 13" along the X axis, rotates 90 degrees and returns to start the next groove and repeats to make four cuts. I ran it on my Shopbot as an air cut. It worked just as I expected. I edited the code in Windows Notepad.
I’d appreciate any comments from experienced code writers.

Your M5 and J5 commands seem to be missing some parameters.

Example:

Code: Select all

M5,13,4
would just move the X and Y axes.


From the ShopBot manual:
M5 – Move 5 Dimensions
{x-location/distance, y-location/distance, z-location/distance, a-location/distance, b-location/distance}
Makes an X, Y, Z, A and B axis move to the designated location or a specified distance (if in Relative Mode) at current Move or cutting speed. These 3-D interpolated moves are made on a diagonal from the current location to the end location indicated in the location/distance values, which may be absolute or relative depending on the Move Mode setting. If a value is not entered for one of the parameters, the value defaults to the current location assuming a comma is used as a spacer to designate the correct parameter field.
