I’m getting my machine in a few weeks. I plan to use a double wasteboard system where the bottom has threads and the top has through holes. That way I never have to replace the one with threads. Due to the added surface height, I thought it would be a good idea to put spacers (3/4 inch plywood squares) below the machine feet so I don’t lose so much space on the Z axis. 1. Does that sound reasonable? 2. How far below the machine feet can I cut? For example, if the machine feet are on top of 3/4 spacers, could I still reach the table top if all the wasteboards are removed? Thanks, Matt ---

I’m planning on something similar using two pieces of half inch MDF. I wasn’t thinking about raising the feet. ---

Matt - welcome to the forums. I believe the max z travel is 5.8" or around there. You can simply extend the waste board below the machine, or raise it if you wish - 3/4" isn’t a huge deal IMHO. -Tom ---

Thanks Tom for the measurements. I agree, 3/4" isn’t too much, but with a double wasteboard system, now it’s 1.5". I’ve considered using two 1/2" wasteboards also. My thoughts about lifting the machine up was because if you can avoid losing space on the Z axis, then why not. -Matt ---

I have 1/2" MDF strips under the feet of my machine running front to back ---

I machined some 3/4" plywood blocks to raise the Onefinity up slightly - so far no issues with this setup but I’ve only had mine for 4 days, time will tell ![image](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/1/d/1d2bead8259172dd5b8ce7bce7cd73fd7a1bce21.jpeg) The measurement to the bottom of the Z axis mount is about 4.5 inches ![image](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/2X/4/44321219db1024fc3656353868e481046ed025ef.jpeg) There is an additional set of mounting holes which will raise the Z axis mount about an additional inch however it then interferes with the routing of the Z axis stepper motor cable. The current working height isn’t an issue for me so I am leaving it as is but I would imagine you could work a solution to reroute the Z motor control wire and gain an additional inch of height. ---

Thank you for the pictures! This is exactly what I was looking for. I will probably do the same when I get mine in a few weeks, then I’ll post back and let everyone know how that goes also. ---

I put my 1F WW on a fliptop, so it’s essentially surface mounted to plywood. I changed the mount of the z-axis from the middle holes (there are 3 sets) to the bottom ones (moving the router down on the z-axis and therefore subtracting that from the total available z) in order for my Makita+bit to reach the surface of my spoilboard (3/4" MDF, so subtract that out like what you describe). Maybe I did it wrong, but with the recommended Makita, I don’t see how you can reach the surface without using the bottom holes on the z, chucking the bit in lower (so it’s not seated _almost_ all the way in–for the record, I don’t think you’re supposed to do this as there might not be enough shaft for the chuck to bite on to), raising the surface up via spoilboard, or some combination thereof.
