Re: Shapeoko 3 Probe & Limit Switch Kit

I like how few wires flex when the carriage moves. I think that improves reliability although maybe it isn't really required as the motor leads and the Z-axis still flex. Cant speak for the motor and Spindle wiring, but I'm using high count stranded wire for maximum fatigue life. I have yet to have...

Shapeoko 3 Probe & Limit Switch Kit

UPDATE: Here is an excellent overview and review of the kit by Winston Moy: https://www.youtube.com/watch?v=a_OctNyLmhI I designed my own limit switch and conductive probing mounts which are really easy to install and use. Mounting is simple with only 10 self tapping screws, and a color coded wire ...

Re: SO3 Gantry Stiffness in Y direction

Cool, thanks for the info. What CAM package are you using? It sounds like you are using some HSM techniques (small step over, high feed rate, long depth of cut). https://www.youtube.com/watch?v=E3AqIZURMbI Fusion 360, HSM all the way. Still can't believe the software is free. https://www.youtube.co...

Re: Some Y-axis travel questions

I'm very interested in a solution to this, I have machine #49 with the same issue and haven't found a true solution yet. I've also squared the machine the best I can with what few measuring tools I have. Don't rely too much on the wasteboard because I discovered mine actually has a couple high spot...

Re: SO3 Gantry Stiffness in Y direction

Significantly stiffer. I get much less chatter than before. It still is weaker in the Y direction, but not nearly as bad. Seems like the V Wheels and the belts are now the major cause of flex. What materials are you cutting with it? I've got a project coming up that I'll be attempting to cut 1/4" 3...

Re: What should I look for in a computer to run SO 3?

I have a dual core Athlon 64 with 2gb of ram, a 500gb hdd and integrated graphics. Runs windows 7, and has a wireless ethernet USB dongle. I save all my gcode from my primary computer onto a shared dropbox folder with my CNC PC. Any computer which runs windows 7 or better should have no issue. ~Andrew

Re: SO3 Machining Aluminum

Got to do a little more experimentation over the weekend. I added (2) .625x1.25x7" long aluminum rectangles as stiffeners to the Y axis plate to reduce flex, which seems to help a lot with the chatter. It's still there, but I would say reduced about 60% With the modification complete, I started tryi...

Re: Fusion 360 post processing

Is there any way to enable a $H homing command automatically in the fusion 360 post processor? I've been adding these manually, but I know there must be a way to do it. When or why would you want to do that right in g code, rather than prior to loading/running a block of g code? I could see doing o...
