I’ve seen other CNC kits use HDPE plastic. It’s the same stuff milk jugs are made of. Very durable and easy to cut out with a router. About $200 for a 4x8 sheet 3/4" thick. So much more expensive than wood, but it will never warp or delaminate either. Any reason why it wouldn’t work to replace the wood ends.
It would work, but vs a $13 sheet of MDF…tough to justify. I would even guess MDF to be more rigid. I have some MP3DP’s made out of both.

HDPE will flex over time. I had a sheet of it in my barn, became a not flat sheet in about a week and a half.
true 1/2" does that,
3/4" is pretty much straight as an arrow through.
Shit, missed the 3/4" part, or just blocked it out. Hmm, if it’s white, some leds to bling it out would be pretty cool looking…
What’s a 4X8 sheet of that weigh anyway?

says 118 lbs. which sounds about right. i always have my local plastic place cut it donw smaller and it’s still heavy.
