Re: Autodesk Fusion 360 - CAM issues

Thanks for the replies. I hope I didn't change all of your answers too much on this. Today I installed my home switches and they seem to be working just fine. I can home it in x/y/z directions now, same as it does in the linuxcnc viewer. I changed a few settings in the stepconfig file, but I think t...

Autodesk Fusion 360 - CAM issues

Here is my setup: linuxcnc with gecko g540 CAD and CAM - autodesk fusion 360 manual homing - jog to x/y/z desired (left top corner of work piece) no limit switches (temporarily) Here is what happens when I run a g-code generated from fusion 360: moves away from stock piece and then starts cutting ab...

Re: Wider belts with bigger motors?

The other issue is availability of wider pulleys that would match a 12mm or wider gt2 belt. I've talked with a guy on ebay who sells gt2 belts, and he can get 9mm but didn't think there was anything wider available to him unless you went up to a gt3 or different style.

Re: Another Laser Diode Engraving Thread

Most of the people discussing these diodes in any detail seem to want them for a much different purpose, handheld pointers or firestarters. I appreciate the extra information. It is good to know readily available lenses can focus these things to such a small point.

Thanks again

Re: Another Laser Diode Engraving Thread

Thanks for sharing. I've read from several sources that those 445nm Nichia 9mm diodes make a pretty wide beam compared to the m140 or 405nm diodes. Is this not an issue or does the 3 element AR glass lens focus it well enough? From some of the images I've seen I'd almost think a cylinder/astigmat le...

Re: Wider belts with bigger motors?

Is it possible to rig a system so that a belt was glued to the extrusion so that it acts more like a rack/pinion system? Most of designs I've seen have spring-loaded motors that apply pressure to keep it against the belt. This would be much less expensive than using custom made metal racks, but also...

Re: Project Shapeoko HD

I got in on the misumi $150 deal a while back, and had to make a quick decision. I decided, mostly based on price, to get the 6090 that misumi has rather than the smaller stuff that was a bit denser. The 8040 has more internal structure while the 6090 was essentially hollow. Their website has all th...

Re: Project Shapeoko HD

Just a few random I wonders: (please forgive my slaughtering of technical terms, obviously I'm not an engineer) 1. How much it help to replace the upper screws on the two z plates with 50mm-ish long 4040 or 4080? This would seem to bind the two plates together so it is more sturdy than the screws. A...

Aluminum extrusion for outdoors?

I saw an advertisement online for a place that sells aluminum extrusion, and they essentially made a lean-to against a house out of aluminum extrusion and built a tiny roof. The idea was to keep the garbage bins covered from the rain. So I had an idea. Is there anything wrong with doing this long te...

Re: Project Shapeoko HD

I bought some of those delrin solid wheels a week or two ago at openbuilds and they didn't have the polycarb at that time. Might want to check out their forum for a few more experiences, but I'm guessing not many have used it for any length of time.
