EA, you shouldn't need any reinforcement. I 3d printed all my plates for a Sphinx and was able to slowly cut new ones out of aluminum. I did mine...
Basic Specs Based on: Kyo's CBeam Sphinx Print Area: 365mm x 610mm Cost: $500-1000 I've been hijacking Kyo's Sphinx thread for a few weeks now,...
I tried uploading some STL files, but it won't let me add them for some reason. Hit me up at bpopp (at) bpopp.net and I can get you a copy of the...
Yeah, and for leadscrew driven machines like the sphinx, you'll have resistance just from pushing the gantry around. For me at least, with...
I used Nema 23 269 oz. You could probably go slightly smaller, but I don't think Nema 17's would cut it (so to speak).
Yeah, I did bond them together using blind joints. I started out with good, carbide bits, but I kept breaking them due to stupid setup problems....
Yeah, that's a good observation. Structurally, it would absolutely be better to expand in the Y direction. Having said that, at these lengths, I...
Savvas, love your videos. There's something oddly comforting about your voice in a non-gay kind of way. :) You wouldn't have any trouble cutting...
****! Applaud you on the grit. That must have taken a while to cut/drill all those plates. Looking forward to seeing your build. By the way, if...
I don't have the adjustment nut tightened down on mine, but I have noticed what might be backlash when my bits get dull. Not sure if this is...
So far I'm using Arduino Uno/GRBL (GRBL 1.1) with basic A4988 drivers. For software, I'm using Fusion 360 for CAD/CAM, and then nextgen Universal...
Sure. Ask them here if you think it might help others. If not, just drop me a private message.
It's a cheap, chinese knockoff so your milleage may vary. Some of them are junk.. some of them are okay. Your best bet would be to buy one that...
Thanks Rick. I'm embarrassed to say I didn't even consider that option. I'll definitely check out the XL gantry plate. I like the aesthetics of...
Probably depends on where you source the aluminum, but the 12x12 6160 plates I bought on ebay were around 6.1mm thick. 6mm is probably a good...
Increasing the thickness just means you'll need longer screws. This can be problematic if screws that are too long might collide/rub on anything....
Problem you will have with the Sphinx design (and honestly, most designs) is that the bottom of the Z axis is going to collide with any tall...
Yeah, I've got this thing in my office right now, so dust/debris management is high on my list. I'm planning on attaching some plexiglass to the...
Justin, I beefed up the design a little bit and it's actually working much better. Aluminum would be better, but so far it's taken whatever I've...
No, the support rail goes underneath the X axis cbeam (slightly darker rail in the shot below): [IMG] I joined the two together with blind...
