Makita Router not reaching spoilboard On Elite Journeyman

[Timrf79 (Tim)]

I just finished assembling my new (first) CNC.
The Makita Router (in the lowest setting on the Z slider) is not reaching the 3/4" Spoil board when fully lowered and the flattening bit inserted to the mark (Amana 45525).
I assume it may be due to the riser… Any thoughts?

OK, may have solved my own problem with this:

I think you’ve likely mounted your z slider too high. Check these bolts, in the photo I’ve mounted as high as possible, but am using a spindle. Your router is shorter. See if you have room to mount it lower.

this is a frequently asked question. Search for wasteboard thickness

By the way, the Onefinity manufacturer says:

@OnefinityCNC

You’re issue is covered in the manual.
You have a Foreman and the makita router, which uses the taller x50 rails on the Y rails versus the shorter x-35 rails on the journeyman and woodworker. Therefore, you must install 2 pieces of 3/4 mdf stacked on top of each other to reach, especially with short bits like a flattening bit.

OK, may have solved my own problem with this:

but be aware that when using such extensions, the accuracy of the cut will suffer. Always take the shortest bit possible for the application.
