Buildlog.net Stepper Shield Sale - Celebrating our 250th!

May has been a lovely month. I thought that we would sell our 250th board in June, but was wrong--we blew past it in May, only a year after starting. In that time, we've shipped to a dozen universities and at least that many countries. To celebrate the sale of number 250, board kits will be on sale ...

Re: A new Z-axis nut - metal on metal w/ built in anti-backl

Well thanks, Will. I'm very happy with the functionality on this one. I did try to find Acme equivalents of the cross nuts with no luck. When I realized how much this would improve the standard setup, I wasn't too broken up about it. I could do some redesign on this to incorporate Acme hex nuts inst...

A new Z-axis nut - metal on metal w/ built in anti-backlash

Before I jump in to the details, here's the finished product: http://www.reactivesubstance.com/remote/shapeoko_forum/shapeoko_z-nut_kit_i045_render_iso.jpg One of my frustrations with the kit, and one that has been talked about at length, is the Z axis. The nut and threaded rod was binding up on the...

Treating spindles as a consumable

....or A Day at Harbor Freight So, I went through two WEN spindles in a hurry. The first was a casualty of trying to work through HDPE too fast and things getting gummy. Sparks and smoke later, the control circuit was done for. The second was a casualty of good, hard work. Lots of further polyethyle...

Re: Job hangs

I'd like to post in light of bjbsquared's comments. I was working late last week on some thin brass sheet with no issues. Two days later, with no changes to the setup, I went after milling some upgraded end plates in aluminum and nothing but disaster. anywhere from 60 to 1200 lines in the thing woul...

New slide/structure idea from OpenBuilds: V-Slot

Mark at Open Builds (and Phlatboys) just finished up a Kickstarter for yet another aluminum extrusion. I was hemming and hawing but decided I'd throw in and pick some up to play with. I have a piece of regular 500 mm 20x40 that I added OpenRail to and it's a really clean product. I respect what they...

Re: Buildlog.net Shield (Rev. 3) and Second Y axis Motor?

Note that there's a silkscreen error on many if not all Rev 3 boards, and the DY and A labels of the jumper are swapped. That's true. But I'm happy to report that I've fixed this on my newest batch of boards. I convinced my PCB house to swap out the silk without considering it a whole new board. :u...
