More Maslow

More Maslow

I tried a test cut on the Maslow recently and had a problem. The plywood circles I cut out before for the filament reel were cut fine. The new test part was a chair leg cut from scaffolding board. As the board is 36mm thick many passes are required to cut the part as I didn't fancy a full depth cut. The problem showed itself as a dropped USB connection. This stops the cut and I had to re power the arduino to get a link back. After some experimentation it looked like the router is generating noise that kills the USB connection. It also seem to very comprehensively kill the WiFi too.

I tried a main filter on the Maslow and computer but that didn't work. Trying to use an old-ish laptop also didn't work as the ubuntu was too old for the software, so that was out. next stop was the purchase of a proper line filter.

This allowed me to cut the entire part (which took about an hour) without a dropped USB connection. I'm pretty happy that this has gone a long way towards fixing the problem, this part took a long while to cut and is one of the biggest ones in the chairs. I may want to cut an entire kit of parts in one go, which would be two of these and some other parts, but I may be able to do that with a deeper cut (especially if I buy a new cutter).

The  sled had to have outriggers added so that it could be stable across the entire board. This worked pretty well too. You can just see them in this photo:

I'm not sure what I'll do if I try to cut from full width boards, this was a smaller board cut from a larger one. I may need outriggers over the top of the sled, or maybe the wider board won't require outriggers on the sled. We'll see.
