Any input would be appreciated. |
Donald,
Hi. I just collaberated with a fellow doing the same thing. He had to slow the travel down to a crawl to keep from melting and it took forever to run a job. Like you, he ran at a fixed rate on the X & Y. I wrote him a small piece of software that reads his g-code files and adds a feedrate to each line whose value is dependant on the Z depth. He is able to define a curve in the software that relates depth to speed. The output of the software is a separate, updated g-code file. I still have a bug or two to work out, but his feedback to me was that he can run a job with no melting, a better finish, and it's finishing about 30% faster. This may be something you would consider trying.
