I live in Australia and the default router is not available here, so I have the DeWalt D26204 which is 240V. There a couple of differences to the 611 which need to be handled.
The power cable points up so gets in the way of the M4 power if it is mounted in its default cofiguration.
The vent pattern on the top router is different, so the supplied mount for the M4 won’t fit.
My solution was to 3d print PCB supports (in 2 parts per side plus mounting plate) and glue then to the top router clamp.
I was then able to mount the PCB 180 degrees from the default, and run the M4 power cable under the PCB and tape it to the router power cable.
This meant I had to readjust the default offsets for each Z axis for BRZ, BLZ, TLZ and TRZ in the maslow.yaml file.
The m4BaseSupport is super glued into the upper clamp. Feel free to use and modify as needed.
By revolving the PCB 180 degrees, so the PCB power is on the side away from the router cable and then putting the PCB power cable under the PCB. There is now no conflict so the cable can go straight up.
This person just replaced the housing on the router itself with a 3d printed one that redirects the cable. This may be nicer long term, so I figure it’s worth at least flagging it even though you’re already “solutioned”.
