Tape splitting ? was created by rmattioda
Is there a way to split large designs into smaller runs, I am using Aspire.
I have heard about a tape splitting post processor, does linux do this

G-code is just plain, human readable text. Any text editor that can handle large files should be
able to split a G-code file into pieces. You select the optimum place to make the split.

I haven't heard about them for years. Originally they were to overcome the limited memory of controllers, by feeding long programs in pieces the controller could read and store.
Typically, the program would be broken where a toolchange occured, or another instance where there was a full retraction from the workpiece and cutter compensation removed etc.
As Jon says you can do it by hand quite easily, you just need header and footer code to paste in whenever you make a split.
How human readable the output from your CAM program is, is another matter.
For some reason none of them space parameters and everything is just crushed together in one line

aspire will split code into parts , or even based on tool numbers . just take time to set everything up , and if need be set up phantom tools
with the same information , and select the order you wish to cut and base your length on the code as you go .
it just takes a little thought , and understanding as to what is happening , rather than just load the code and post process it , and accept the outcome
take your time to understand what aspire is doing , and it will all become clear .

Going to give this PP a try tonight, it batches the files into however many lines of code you desire.
this comes from the Vectric PP guide in the manual
opinions?
