Re: n00b questions

Hmm, lots of questions. Yes, you can extend the shapeoko, there are several people who have done it already. It is not trivial, but is doable See this for an example. Oh and yes you definitely need the double y-axis motors for that. In reality you really need that to do most things.... Machine does ...

Re: 3D Profile of Reddit Alien

I used LinuxCNC to mill this. The gcode file is 35k lines, so quite a lot of segments. So do I have incorrect settings in LinuxCNC for the lookahead? This doesn't seem like a practical way to mill arcs in a 3D profile. Will, what tool would you recommend that makes arcs instead of segments? I have h...

LinuxCNC Installation

So I got around to installing LinuxCNC. I used an old desktop with a parallel port. It was single core and I tried both the Ubuntu 10.04 and 8.04 distribution of LinuxCNC. Surprisingly the 10.04 distribution worked quite badly and had really high jitter when running the latency test. The LiuxCNC for...

3D Profile of Reddit Alien

So I have wanted to explore the potential for more sophisticated 3D profiling for some time. The pink foam at home depot (Foamular) seemed like a good material to use for such tests. It is uniform and does not have the voids which the white foams do and comes in 2" thickness allowing for some large ...

Re: Carbon Fiber Plates and Aluminum Bearing Blocks

Wow, that is super cool. You are so far ahead. Do you have any details on the CF?? 1) Where did you buy it? 2) Is it hard to mill? I have heard CF dulls endmills? 3) How do you manage the dust? I am think CF dust is ultra bad for lungs and shop? Awesome otherwise, I am trying to do all the stuff you...

Re: Totaly lost Need Direction

For the DW660 see this thread . Everything you need should be there, post a message if you can't get it to work. The DXF to gcode conversion can be a little tricky, but is doable. I can help you get through it. What CAM software are you using? I recommend downloading CAMBAM to get started. It is a f...

Re: Upgrade Parts!

It would be cool if someone could use their own Shapeoko mill to make these plates out of aluminum. I would try, but need to finish some upgrades first, before I start milling aluminum again.

Re: Chips and dust - suck or blow?

Ok so aluminum probably needs coolant in the ideal case, however there are many many videos on youtube showing both hobbyist and industrial systems cutting aluminum without coolant. Considering the smell and mess of coolant, I would rather go the dry route. What do laser cutters need that much air f...

Re: Chips and dust - suck or blow?

That sounds good. Perhaps milling aluminum without any coolant (correctly) is in my near future.

Re: Upside down and Backwards

Can you post the output of your GRBL when you type in $ so we can see your settings? If the software inversion does not work for you, another option is to invert the stepper motors by switching the wires. First turn off all of the power to the steppers (or you will fry your drivers), then reverse on...
