Just starting to learn how to use my machine (SO5) and figured a simple box was a good place to start, but I can’t get a tight fit between parts - every lid is too small and pocket too large (like 0.3mm deviation per part). It feels like I’m missing something simple or fundamentally misunderstanding what’s happening so looking for any thoughts before I start designing parts with windage. I didn’t expect a perfect fit, honestly expected they wouldn’t go together at all, but is this normal deviation in wood?
I designed up a dummy part to be cut as one job then separate the halves to make sure I wasn’t introducing any funny business between jobs, but still things are off. Other things I’ve tried:
- Swapping cutters (using cutters from Carbide 3D, so I shouldn’t have goofed on the cutter diameter, especially in Carbide Create)
- Using two types of cutters (201 vs 251)
- confirmed cutter diameter
- Changing from Carbide Create to F360
- Changed stock material from Maple to plywood
- Switch from Imperial to Metric units
- Checked every fastener I can find
I’m scratching my head - the parts are measuring the wrong way for play in the router
Here’s the part designed and processed in metric in F360 with no sanding on the face, just knocked off fuzz on the long edges. Don’t mind the measurements too much since this is pretty soft material for calipers, mostly just trying to help visualize the problem.
Good news is it was super easy to get everything assembled and running!
