3D Printer test pad for setup

This is a test pad for adjusting squish and Base layers. After your Esteps are dialed it do a fairly loose paper leveling. and you have done testing to know what temp you nee to run that filament at. In your slicer add a Brim to this and adjust your squish on the fly. start adjusting the brim slowly as it makes the rounds til it flattens out and looks right. restart if you have to, now you can dial in the first layer while its running. you can always stop and restart that layer as needed also.
