I need to investigate the open source offerings.
Ha! Me too. I also use OpenSCAD. Easier for the programmer in me.

Re: Stepper driver options for LinuxCNC

Be sure to post how it works. It looks to have a lot of promise. Much more so than the RaspPI. Has a lot more IO too. Its pretty easy to run up against the limits of the parallel port.

Why do you need USB on the tablet?

Re: Upgrade Parts!

It's was my fault. Wife was on the fence regarding buying a silicone molding kit. She made up her mind yesterday, so of course the plates are available now and we can save shipping.

Re: What is my problem here?

Having two steppers on one driver splits the current between them. Your driver has enough current capacity to drive both (2 * 1.2A < 3A) but keep it in mind while adjusting the driver. The two stepper won't split the current evenly because of individual variation so be a little conservative. Having ...

Re: Milling problems

A lot of the rigidity issues can be solved by reducing depth of cuts and reducing feed speed. (In my experience). My Shapeoko is stock + dual Y. No problem with precision. Just takes a bit of trial and error to get the parameters right. I do plastics, aluminum, and PCBs. That said, I do on planning ...

Look at freckleface.com They have cheap thick large cutting boards. Would make a good coolant safe table.

Re: Water or air coolant for your shapeoko?

how many flute? 2 flute. From drillman1 on eBay. His price is really good too. Wish he had a 1/16". Really nice endmill. Had a bit of an oops with it. My CAM uses a G28 at the end of a job. I recently reinstalled LinuxCNC so it defaulted to 0,0,0 in machine coords. Did a rapid right into a 1/8" alu...

Re: X and Z mods

It's been down for maintenance for weeks (months?). Anyone know what's going on?

Hope everything is ok, Bart is a great contributor to the maker community.

Re: Milling problems

Dual Y should be default. Mine was completely useless without it. I got racking on the sharpie hello world unless the eccentric nuts were very loose. I already had spare stepper and a 4 axis board so the upgrade was cheap and painless for me. Flipping X is a free upgrade. I haven't done it (just goi...
