Re: Gryphon CNC extrusion

Just my two cents but CNC Mogul and Gryphon must be owned by the same guy or at the very least both companies are working together. I say this because their machines are identical other than being different colors. CNC Mogul is not an open source machine, so it begs the question how the other compa...

Re: Gryphon CNC extrusion

Doesn't the Gryphon have two of those beams, one above the other? Should it really need that? Or could it be that the beam doesn't resist twisting force significanly better than a pair of Makerslides bolted together? Actually I'd rather like it to have 3. If that was the case it would support a 5hp...

Re: Gryphon CNC extrusion

Joel, may I ask what tools/WOC/DOC/feedrate/rpm are typical for your production work? I want to calculate what sort of cutting forces you've found usable on your machine. Of course the speed is dependent on the material. On hard maple with a .25 uncut we make .3"-.4" passes around 90-110ipm. On wal...

Re: Gryphon CNC extrusion

I have a 1000x1000 ShapeOko, the first generation with 'tinfoil-thickness' (OK, they're about 2mm thick steel)motor mounting plates on the ends of the X-axis, and with my NEMA17, 6mm wide belts and a putzy 300W Chinese spindle, I get better than .5mm every bl**dy time. the NEMA17, the pulleys, the ...

Re: Gryphon CNC extrusion

Custom belts on custom systems maybe all hunky-dory for hobbyists that have time to construct the various odds and ends, machine parts, but I can tell you that once you add nema-23s and a trim router to the shapeoko 2 the 5mil (or whatever they are) belts won't even come close to cutting it. Or expa...

Re: Gryphon CNC extrusion

I did a quick video that briefly goes over some points. A couple things I would mention to some of the "CNC connoisseurs" (er... snobs) here: 1. Gryphon is very much like the CNCMogul. However I can't comment on that since I've never owned a CNCMogul system. However I do know that they are two diffe...

Flashing GRBL onto Arduino via Mac OS X

(this post won't help you if your arduino is damaged or the boot loader is dead - however you'll know if you run thru this reload and you still get a programmer error) I needed to reload a couple of Arduino spares with GRBL (they had been overwritten in a haste of trying a new CAM software). I tried...
