LR4 table onshape questions

[Jason_Fair]

Hey everyone,

Could someone give me a coles notes version of what I should be doing in onshape (I am a beginner) when it comes to modifying the LR4 table for my size CNC? I am honestly totally lost at what I need to change and why. For example, my CNC is a 3x4ft capable machine.

I really appreciate it!

you need to modify the cad parameters to suit your build size using the values from the calculator ( lr4 calculator). X & Y usable space

Can you specify what table are you looking at? Ryan’s or Jonathan’s table?

okay, thank you! I will try this out!

I am looking at Ryan’s table. I havent been on the forums in a while so I will also look at Jonathan’s table to see the differences.

Thank you!

Using the calculator, for the 3x4ft table, I have set my table to 1251mm width and 1583mm length to give the extra 50mm suggested.

Questions:

1. Is that really all I have to do? I assume that when I get my material to build this, I will have to adjust the blocking_thickness and material_thickness?
2. Does this look sturdy enough to build into a hinged table that goes 90 degrees?
3. How do I get a BOM with a parts list created from this? Or how do I measure what I need from the drawing?

Thanks!
