I picked up the new base for my XXL yesterday. The finish on the MIC 6 was like a mirror . I could just imagine how the shop lights would reflect back at me. So today decided to engine turn a pattern into the base. Not to sure that I would want that as a everyday job!!. Tomorrow I will be pulling the old base off and installing it!!
Alright, you have to let us know where you got it and (if you don’t mind) what it set you back. I am talking with Ohio Diesel Parts, since they already make a set for the XL and they are working on an XXL plate.
It’s preliminary right now, so not sure if it is going to be 1 plate or 2.
Trying to decide if I want to go with a plate like that tapped at 2" with 1/4"-20 or go with the Misumi extrusions I’ve seen. I like the idea of the T-slot, but I also prefer the drop-in ability with a 0.75" aluminum bed that is a drop in replacement for the MDF bed.
When originally quoted on the job I chose .5" 6061.($675 for the 6061,$800for the MIC6) When he recieved the piece of 6061 it had a 1/8" ridge in the middle of the piece. Long story short the piece I got was a drop that he picked up for a great price. It has a really nice flatness tolerence of .015.
Waiting for all these XXL initiatives to come to fruition… I just got back from CES and I’ve been out of touch here. Russell has posted up some 2-panel base plans, but I had issue trying to verify his .step file. I had also emailed Ohio Diesel way back, and pleased to learn here they’re looking at an XXL offering.
I did an ali base for my S3, I really over complicated it.
Get some aluminium of the correct size and thickness. Mark the frame holes and hand drill, only 2 of the holes need to be sunk and those are at the front then use the Shapeoko to mill the mounting holes - it’s what I wish I did rather than messing around designing a base getting quote then not even using it.
I’ve seen your rig, Luke… you epitomize “hacks” to Shapeoko platform, so your comment comes from one that “has the T-shirt”. If one could get a thread cutting mill to complete the second half of the job, you might be onto something. I’m running ESTLcam which does support thread cutting, so this suggestion of yours just gained some traction…
what I’d do is drill the m5\m6 holes with the shapeoko then drill tap the holes.
I think for my wasteboard drilling the holes by hand (electric drill) took about an hour. If I recall I have about 100 holes. Tapping took less then 10 min using a m5 drill tap in my dewalt drill.
The main reason for recommending this other way is a cnc milled waste board is very expensive and let’s remember it’s a waste board it’s devastating when you hit your shiny new waste board with your mill…
Unless your producing many boards the cost won’t come down (I looked at small production runs). The actual frame mounts don’t actually need to be all that accurate (2mm deepening the size of bolt) as you have to square your machine. By using the shapeoko to mill the holes you get the best of both worlds, lower price tidy look and feel.
I did my whole board by hand and I wish I used the shapeoko to mill the holes - whilst mine are at 5cm spaces I can see some are slightly off - granted it makes no difference to the work holding.
Something to think about when making one for the xxl is what type of items are you milling? If only big things you need less holes. In my eyes the main benefits to the aluminium base is the ability to stick things to it, and the ridigity.
I do allot of small items under 15cm and I’m considering making a small nomad style board that bolts onto normal wasteboard.
My “nomad sized” board is about 15" square, and has a bunch of threaded inserts in it. It’s then attached to the lower board, which has t-tracks. If I had it to do over, I’d probably do the whole thing as one big threaded table. At the moment, the “subtable” is mdf, but have been meaning to replace it with an aluminum one.
Is this the XL one you’re talking about? https://www.amazon.com/Shapeoko-Custom-Aluminum-Fixture-Mounting/dp/B074JHDPNP?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-d-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B074JHDPNP
Yes, that is the one.
