I am still building my machine on weekends and I noticed that the Z axis has 144mm travel while the wasteboard which will sit above the bench is only going to be about 50mm from the bottom of the Z carriage. This means I am not able to use most of the Z travel which is stupid. I have checked out the numbers and the space and I could put 100mm spacers under the foot mounts of my X50 and at least be able to use most of the Z travel . . . . . so how come nobody mentioned this to me? Has anyone else done this? Any suggestions for a solid and even mounting block? At the moment I am looking at stacking up about 8 layers of glued plywood.
Comments and suggestions welcome !
Have a blast with your machine by the way!
Checkout what @HardtailSr has done in this thread with vertical clamping. It was really creative and there are several others who have done cool things to take advantage of Z-travel; it’s a fun thread.
Thanks for your post, I am not going to use 3D printed mounts though, they just don’t look strong enough to me - Reckon I’ll continue with my previous plan - I think I prefer raising the whole machine rather than just the X axis. I will post my progress here: The Empty Header
if anyone is interested. Thanks again to everyone here, I really appreciate your help !
The router/spindle can be mounted in multiple vertical positions so there’s already a bit of adjustability.
You can have a table with a giant cut-out in the middle giving you multiple feet of space under the carriage/spindle, but that clearance or any clearance achieved by risers, obviously doesn’t increase your travel, it just allows you to work on larger/thicker parts.
What materials are you planning on working on?
The issue with creating a large (tall) clearance beyond the travel length is the inability to then machine thinner stock without raising it up or possibly using a very long bit (which can lead to more deflection/breakage). It’s a balancing act, and one of the benefits of doing it on the X is that when/if you want to reverse it, you don’t have to re-square the machine and there are only two risers instead of 4 to deal with.
