Genmitsu CNC MDF Grid Spoilboard for 3020 CNC Router Machine, Compatible with 3020-PRO Max & V2, 300 x 200 x 12mm, M6 Holes (6mm), Screws and Wrench Included

Got this to avoid damaging the aluminium bed plate on the 3020 machine - does the job as it should - nice gridlines on it and holes that line up with the clamp points on the metal bed.

Perfect for the first time users of the 3018 range as this will take away any fear of damaging your bits by driving them into the aluminium bed.Super easy to install by lining the T slot nuts into place and tightening (don’t over tighten). I recommend a gentle tightening across all 6 T slot nuts with a gentle force applied on the spoilboard so it’s making even contact while being clamped down.Talking of clamping down, you have multiple points throughout the spoilboard allowing you access to clamp your work to the spoilboard if needed as well.Another reviewer has stated no need to surface the spoilboard, but I recommend that you do so, as otherwise you might not have a true and flat surface. Search for “Sainsmart Genmitsu CNC Users Group” on FB and you’ll get plenty of help with surfacing your spoilboard.Only niggling point I have is the price, which I believe could be a bit cheaper, but hopefully through time the price will drop.

Expensive piece of MDF. But you need one to protect the bed.

Excellent product. Well made fits perfectly.

Really handy for smaller pieces of work
