Raise cnc to accomodate 100mm thick material

Trying to figure out if there is an easy way (temporary) to raise CNC to allow cutting of 100mm thick material?
Any ideas?

My two cents…
Raise the CNC above your current work surface with layers of MDF under the leg assemblies (Y axis) as required to get the clearance you want. Not sure about the bit length nor whether or not the router can handle the change

Thanks : that was my first inclination.
