Re: Can I make a sketch into an SVG file?

Both adobe illustrator and inkscape have convert-to-outline (tracing) tools that can do this. However, depending on the nature of the sketch, you may need to do a lot of mucking around in the trace settings to get what you want, and then a lot of cleaning up after. Both packages also have SVG export...

Re: How do you cut your tabs?

Lots of different options work, as shown by the number of replies. I like a japanese keyhole saw.

Re: Wooden Box with Miters

edit: didn't see WillAdam's post. Yes, what he said. Edit: actually, one additional thought: what if, rather than trying to cut two matching mitered faces with box joints within them, you cut a triangular, right-angle-triangle groove along each miter face, that a piece of square dowel fits into. It ...

Re: 2.5d or 3d

Another option for making simple, 'organic' type shapes without actually getting into 3D modelling programs is to do a simple gradient in a drawing program and then import it as a heightmap in you CAM software. Here's a simple gradient, imported into CAMBAM (Draw -> Surface -> From Bitmap), and a re...

Re: G-code sender Sends Zero to X 0,0,150+ ... not 0,0,0

How are you setting a new zero? Are you using the button in UGS? Are you sending a G92 x0y0z0? G10 L20 P1 x0y0z0? If you haven't tried it yet, try using a G10 command to zero your G54 coordinates, set G54 as your active coordinate system, and then go to x0y0z0 again. I had an issue on mine with a ne...

Re: few ? about grbl 9b

I've got a somewhat atypical Shapeoko 1 (much longer x, slightly longer y, much beefier z with acme rod, optical limit switches, drive-shaft dual setup), but I can share with you what I've got for settings: $0=87.490 $1=87.490 $2=125.980 $3=2000 $4=2000 $5=700 $6=50 $7=50 $8=50 $9=800 $10=250 $11=10...

Re: few ? about grbl 9b

After taking a while to troubleshoot the settings, I've got the current dev build (with the fixed homing mask) working, and it does seem like a big improvement over 0.8c, in terms of the smoothness. However, this build has a dir port invert mask, which I don't think the 0.9b(20131210) or any previou...

Re: Homing within a part

Because occasionally my machine will miss steps, and while these missed steps might not be noticeable in a single part, it will become noticeable if there are multiple missed steps over the course of a complex job. By homing after each part, I know that these missed steps are never going to escalate...

Homing within a part

Is there a way to get the system to home itself midway through a job within g-code? For example, what I'm trying to set up a job using nesting in cambam. My intent is that at the end (or beginning) of each iteration, it homes itself, returns to the correct workspace and location, then continues the ...

Re: Move after Homing to a position

Another way is to use the saved coordinates; I believe GRBL 0.9 saves them in EEPROM, so you only need to set them once, but I don't really understand how they work; I've always used G92 and it worked for me. I've never used $N, so I don't know whether these work in that context (they should). I've...
