That write-up has my design for custom arms (to replace the stock black arms) and so on (including my custom SmokeSucker to add Suckit-compatible laser smoke extraction).
The custom arms clear the EasyTram hardware and give wider clearance for the router at top of Z travel while not reducing X travel (even in my case with swapped Y plates). Also required are spacers to mount the new custom arms and spacers to widen the boot’s reach (unscrew the magnetic sliders, add the spacers, and screw it back together with slightly longer #6-32 3/4" socket head cap screws). There’s enough adjustment in the magnetic sliders to account for the front/back positioning.
