When I start a Vectric toolpath, the spindle moves to the start of the toolpath and starts cutting before it reaches speed. Is there a way to insert a permanent command in the Post Processor to delay cutting until the spindle reaches speed? I know I could do this in Mach III but I don't want to have to do this individually for every toolpath.
I an using Aspire, (G Code (inch) (*.tap)) Post Processor, Mach III, and have a Velox CNC.

Re: How To Delay Cutting Until Bit Spins Up?
The post processor could be modified to the appropriate g-code for Mach3 to pause until the spindle comes up to speed.
I believe that code is:
where <n> is replaced by either a number of seconds or milliseconds depending on how things are setup in the Mach3 configuration. If Machi3 is set to interpret the P as seconds you might use something like:
to wait 10 seconds.
Something that I'm curious about: if your machine runs Mach3 why not use the Mach3 post processor rather than a generic g-code one?
I believe that code is:
Code: Select all
g4 p<n>
Code: Select all
g4 p10

Re: How To Delay Cutting Until Bit Spins Up?
I was hoping there was something I could do in Aspire one time but guess it has to be programmed in Mach III. I'll do some more research.
Regarding the generic post processor. Good question. I can't remember why I picked that. May be Velox suggested it or may be too many iterations of Mach III post processors and didn't know which one to use. But I've had the machine set up this way for over three years with no problems so.....
Thanks for your help!

Look at the post processor editing guide. You can easily add the G4 P# code to your post processor template so its included in every tool path you generate
