Ah, thanks. I appreciate the helpful info!
I did this for laser, worked great! I bought enough magnet strips to also do CNC too! Will aim to get that tried soon.
That does sound like a great idea, i am concerned about the CNC but then again i dont use it yet. and we could always add extra clamping to the cnc table anyhow.
Thank you for sharing this idea.
One idea would be to stick the magnets oo thst all holes on the underside of tbe wasteboard are covered. Then you cannot damage the bed as the screw will meet the magnet and stop.
Good idea. I started this topic, and I’ll say I’ve used the magnetic strips for multiple CNC and laser jobs. Of course laser is no problem since the only force is bed movement. But, at least for me, CNC is fine also. Put enough strips on, the lateral hold force is good. You’re not going to get much lateral force from the small cut depths the head will do.
You obviously haven’t done much cnc. Reliefs are one thing where the bit is only contacting the surface. The force on deep cuts (12mm) against the grain in hardwoods like oak is significant even with smaller bits, let alone when using 1/4". I’ve had things clamped down where I thought the inserts were just about to pull out and still have had the piece shift.
Definitely would need a locking mechanism for me. Guess it all depends on what type of work you’re doing.
I 'm amazed the spindle on the snapmaker can cut that deep. I’ve been cutting 4mm ply with no problem at all but using multiple passes. Oak? That’s a different story. It’s a pain to work even with ‘real’ tools, hard and splintery. Magnetic mounting works for me. If you don’t like it, don’t use it.
I have done something similar for the laser bed only so far.
I used an old “damaged” magnetic bed, laid down painters blue tape on it, then did the same to the back of the laser bed aluminium rails and then I glued them using wood glue and left them overnight. Now I have a super-fast removable bed and it’s rock steady. Plus it’s easily reversible as I only need to remove the tape - there is no glue on the actual plates! The Snapmaker team should have opted for this in the original design as it really adds a LOT of VALUE to the process.
