Replicator / 3D Printer Test Pattern Generator Program

This program generates a test Gcode program to be run on your 3D
printer.The test pattern will try a range of test parameters across the X-Axis and a different range of test parameters across the Y-Axis.
For example, you can test different feedrates and different layer
heights in a single test.
All the other static operating parameters are set and don't change
for the duration of the test.
Currently, there are two other independant tests:
There is also a maximum 'E' feedrate test to check for slippage of
the pinch roller and there is a KissSlicer 'Flowtweak' test cube generator that will allow you to make 10 different test cubes at one time with varying 'flowtweak' values. This will help you find the optimum extrusion rate for your nozzle size.
