All of my products were designed around GRBL 1.1f. They'll likely work with 1.1h but I have not tested it and don't want to point people towards potential problems. Also, none support the self-squaring gantry feature - take the time to build a solid and square machine rather than relying on tricks to force the structure into alignment and risk damage.

The Uno Shield has sockets for the onboard A4988 or DRV8825 drivers but you can run jumper wires from the correct spots for step, direction, and enable to your external TB6600 drivers. If you take a look at the last page of the attached datasheet (center of the page, labeled A4988 Carrier), you can see the enable pin is the first one/top on the left 1x8 header. Step and direction are the bottom two in the same left 1x8 header with direction being the bottom one and step being the next one up.
