Re: molex connectors & alternatives?

Removing molex pins is easy once you get the hang of it. You need to use something thin and metal (bobby pin or bent paper clips work) to push in both sides of the "wings" at once, and then it just pops right out. Once it's out you may have to bend the wings back out, but be gentile as they are a bi...

Re: What features would a new Shapeoko app need?

I'm not an open source zealot by any means (I write software every day that isn't, and it pays the bills) and I tend to think that the FSF and GNU license are unrealistic and do more harm than good to open software development, preferring BSD style licenses. But that's philosophy and everyone has an...

Re: What features would a new Shapeoko app need?

I had thought of the same thing as PsyKo, but eclipse as a platform has poor documentation without buying a book as far as I can tell, and SWT seemed too alien to me coming from using swing every day. However its plugin architecture would be great for adding features over time, and hooking the "send...

Re: GCODE Step and Alignment Tool

Well, looks like someone finally beat me to this. I've been contemplating a "gcode IDE" for a while now, but was having a hard time getting started. I guess I'll have to find some other way to add to the community. Too many software developers on this board :)

Re: Upscaled Motor Advice

I'm not certain why you want to use such large motors. User ImprobableConstruct is running a scaled up 'oko similar to that size, and is still using nema 17s if I remember correctly. Adding that much weight to the gantry is just going to make it require more power and supporting electronics to maint...

Re: Wedding sign

I'm planning on making a sign for my workshop, but can't decide between Papyrus and Comic Sans. Will, what is your suggestion? (ducks)

The sign looks really nice, I'm sure no one will notice the apostrophe, unless it's a family of typesetters or graphic artists.

Re: StepperX: New complete Hardware GRBL solution.

Maxim has a nice application note on isolating USB from the rest of the system using optocouplers. It's somewhere near the top of the google list so you may have seen it, but I ran across it the other day and thought it was interesting http://www.maximintegrated.com/app-note ... vp/id/3891.

Re: Grbl Controller 3.0 released

Another solution to homing is to use custom builds of Grbl that lock the steppers by powering them even when they are stopped, which greatly reduces the chance of bumping the steppers. See this topic (although it is for version 0.8a) http://www.shapeoko.com/forum/viewtopic.php?f=3&t=533 This is now...

Re: eShapeoko #23 or MadManMoe's Marvellous Milling Machine

A fellow cable sleeving addict? Paracord is pretty nice, gives it a finished look for not a lot of money. I need to get some of the larger diameter kind, I was only able to fit one wire through, so mine doesn't look quite as neat as yours.
