Lots of confusion around VCarve (And Aspire) Post-Processors for Carbide Motion.
These Vectric provided post-processors provide basic tool change support to save multi-toolpath files.
Issue #1: No Shapeoko has an ATC Automatic Tool Changer. Labeling it that way confuses people. This one supports the Manual Tool Change Prompt in a limited way. It displays only the tool # from the database in the popup. The PP can be edit to add the name to status field.
Issue #2. The description says the file extension is .nc but its written to save as .gcode More unnecessary easily fixable confusion.
Issue #3: Vectric also still includes this way out of date one with no tool change support.
I don’t have any included with VCarve Pro with TOOLCHANGE in the title?
I never had the issue with duplicate tool numbers. I might have renumbered mine before I saved files. I save multi-tool files all the time.
If you haven’t already read through this post when time allows. It has a set of post-processors now maintained by @Allen44 with many enhancements which is a great service to the community. I use my own hombrew PP from what I learned in that thread
