My machine is a tease. It has a cutting area of 24"x24"x3.5". I’m using the Makita RT0701C. I have tried cutting a large sign out of 1/2" Birch plywood. My first attempt was going really well. I used the downcut bit from V1. I was cutting at 30mm/s at 6mm DOC. I hadn’t intended on cutting that fast, but I forgot to change the tool It still managed to cut fairly well. About 80% the way, I lost the bit. Not sure if it snagged something in the plywood, grabbed something on the spol board, or it just wasn’t tight enough.
Since the first attempt was working well up until then, so I figured I would just give the same GCODE a go. Only now it cut like absolutely garbage. Checked all of the belts, grub screws, and they seemed tight. I thought maybe it was the bit so I bought some replacements on Amazon. I tried a bunch of test cuts on the messed up boards and things seemed good. So I bought another section of birch. This time I slowed it down to 15mm/s and 3mm DOC. It started out fine, but then I started getting some bad cuts. I let it go, but dialed the speed to 50% so it started cutting much slower. It didn’t seem to make much difference. The bigger cuts seemed to go well, but the smaller stuff is where the bad cutting is noticeable.
I’m not smart enough for this machine. Every time I have some success, it doesn’t seem to last. Here’s some photos and a video. Looking for some help. Let me know what other information that is needed, but I appreciate any help.
