From the start I want to learn how precise the machine is by installing a pen refill instead of a bit, and "drawing" the design on some reasonably thick card, double-sided to the sacrificial bed.
Comparing measurements will identify errors in my method, design, code in both path and depth and instill an understanding of exactly how the eagle interfaces with the mill.
This might also highlight the deficiencies in the 3020T and provide a before/after comparison.
Enjoying the learning curve and brain workout.
My eBay search is still operational.
Thanks for continuing advice.
