Re: twforeman's Shapeoko 3 #0004 Upgrades - Long

This is a great thread - very informative. Since I've rebuilt my table a few times I find it very interesting. One (perhaps dumb) question. Why the torsion box? I know a lot of people use them, and I've built them myself before, but only for heavy tools. The S3 isn't that heavy. I've gotten away wit...

Re: Nervous...

I installed a big paddle emergency stop switch (E-stop) on the front of the table. Wired it between the wall outlet and a power strip. Then the controller (stepper motors) and router power cords get plugged into the power strip. I bang the E-stop and power shuts off to the stepper motors and router ...

Re: bCNC & autoleveling

Yes, that's correct. After completing the Autolevel, you jog the spindle anywhere inside the probed area, and then you click the BCNC > Probe > Autolevel > Zero button. At that point the widget code is automatically adjusted based on the probe data. You can see the grid of height adjustments suddenl...

Re: bCNC & autoleveling

Hi Alain - No, I haven't found a fix yet. I posted the issue on the bCNC Issues forum and got a couple of responses, but neither of the suggestions has helped. If I get a process to work I'll write up a description and publish it. The capability is definitely there -- You can use the Autolevel funct...

Re: I'm a New Guy and Need some help getting started.

It doesn't really matter. You can start with the inserts (they're cheap) and see how you like it. As time goes by you'll get a better sense of the kinds of jobs you do and the clamping methods that work best. Things evolve. On my first wasteboard I drilled holes randomly for inserts whenever I neede...

Re: Grayscale image to gcode

I've been getting some nice results by converting the original source image to bmp format, and then using F-Engrave in Vcarve mode to generate the gcode. http://i.imgur.com/yK0o7fK.jpg Not sure about grayscale however. When I start with a grayscale image I use Photoshop to push the contrast so I get...

Re: bCNC & autoleveling

Oh, no, it does work :) . The autolevel feature does not care if it is probing PCB deviations (~0.01 mm) or a cylinder surface (~10 mm). Exempli gratia:

It's a little hard to see, but this spirograph form is equally deep all along the curved surface.

bCNC & autoleveling

I've been using bCNC for a while now and I really like it. But I'm running into an odd problem with Autoleveling. I must not be looking at the process correctly. I want to incise a logo into a curved surface - like the edge of a hockey puck. So I set up the object in my vise, covered the surface wit...

Can I use the bCNC probe function to digitize an object?

I just started using bCNC. It seems more powerful than UGS, but the documentation is somewhat limited. I haven't been able to determine if I can use bCNC to reproduce an existing 3D object. I thought I might be able to use the probe function to digitize the height of the object Then save that data a...
