Re: My first "real" project

That looks beautiful. How did you apply the stain to the letters and not have it drip all over - like it always does for me?

Re: Anyone At Maker Faire NYC?

What happened to the 3D carving lecture that was supposed to be led by Zack Kaplan on Saturday? They had us wait 15 minutes only to tell us that it was canceled. I was really disappointed in the lack of CNC milling stuff there. There were 500 different 3D printers and just a few routers - and zero S...

Re: Can I go from Inkscape to F-Engrave?

You can try Gimp. It's a free Photoshop-type software. It can handle a ton of different file formats.

Re: shapeoko losing calibration ?

Something similar happened to me. In my case it turned out that the steppers were missing steps. It wasn't obvious until I started really tuning my machine down to the fraction of a fraction of an inch.

Re: LinuxCNC with parallel port breakout board and Pololus?

Thanks for the info.

I have an old PC with a parallel port and the stepper drivers, so really a few buck on an Ebay parallel port breakout board and a cable makes for a very cheap way to try LinuxCNC.

LinuxCNC with parallel port breakout board and Pololus?

I'm looking to try LinuxCNC with my Shapeoko. Anyone have experience, or any info, on using one of these cheap Ebay Parallel port breakout boards with four Pololu DRV8825 stepper drivers? http://www.ebay.com/itm/Upgraded-5-Axis-CNC-Breakout-Board-for-Stepper-Driver-Controller-Mach3/201081436584?_trk...

Re: Z axis issues - either too deep or too shallow

I'm still struggling to get my machine to operate as it should. I just ran the Circle Diamond Square Test linked and the Z was either cutting too deep or too shallow. :evil: I've run all sorts of tests using Makercam and Inkscape, running the code through OpenScam (and UGS's visualizer), and everyth...

Re: Z axis issues - either too deep or too shallow

Thanks for the help Will. So you think the Steppers are missing steps? Always possible I guess. I have the drivers cooled with a fan and have some experience with Pololus from back in my 3d printer days. The thing is the Z height is screwy in repeatable ways. In UGS it does one thing at the same poi...

Re: Z axis issues - either too deep or too shallow

Would a metric/imperial issue make these issues though?

I just tried a simple circle pocket cut made in Makercam. The machine cut the first .05" pass, retracted Z, moved to the center of the circle and plunged about half way back and started the 2nd pocket pass, cutting in the air.

Re: Z axis issues - either too deep or too shallow

Maybe, how would I check that? Or avoid that?
