Hehe getting fancy with LED. Turns out the openbuild 2020 extrusion has a nook that is good not only for hiding gt2 belt but also LED strip :)

Has anyone built a 1500mm by 1500mm CNC machine with 8mm lead screws? Just wondering, as that is the size I am drawing my plans up for. If I need to go larger lead screw, then I can, but wondering if using thrust bearings at the end of each screw to put tension on would be sufficient to mitigate whip.

Look at this as an alternative belt drive, no belt stretching, its called bell everman belt drive.

+Brandon Satterfield​ how does this look for a heavy duty R7 y-axis?

1500mm c beam
1500mm 1605 ball screw
400 something oz/in stepper from www.automationtechnologies.com

These plates were the first things I cut using planetcnc controller/software and I have to say it is absolutely amazing. The electronics setup is a little more expensive, but WOW it is everything you could want for cnc. Blows the open-source stuff out of the water.

I plan on doing a review of it here or on openbuilds once I get some more time in it. I was pretty skeptical about trying it since there is not many using it, and I ordered it directly from planet cnc- the other side of the world.

What is the reason for the jagged cutting lines. Too much teeth (GT2 pulley with 30 tooth) or belt tension or microsteps (Nema17 with 1/16) or PWM Hz?

from a close look at your picture, those little wavy edges are from the PWM rate of the laser power control being close to the travel rate somehow. like the laser is pulsing slow enough to be 'visible'. cut slower, maybe? or increase the PWM rate.
and
there is backlash in X and Y. tighten set screws, tighten belts, and make sure there are no sticky spots in the travel of both axes.

Alex figured out how to beat the system. Lol
 
Playing around with different lists from Amazon to lump together items needed to complete projects when opensouce choices aren't available to offer a B.O.M. as a single URL and one of my favorite things is you can get +OpenBuilds​ parts from Amazon :) makes a great way to spend those Amazon Gift Cards that are burning a hole in your wallet

I know there are some awesome project makers out there. Post your favorite project!
 
Care to take a challenge? Please post your favorite project you completed this year... This can be a machine built with Openbuilds parts or something you created on a machine using open builds, let's think of this as a OpenBuilds Year in review. I will start off the challenge with a hashtag #OpenBuilds2016 and add that this was done on +Mark Carew​'s infamous Ox CNC

I'm looking at downgrading from my DeWalt to a small air cooled DC spindle. I'm converting a particular machine to just cut wood and HDPE, and as I have this in my home office (no garage), the less noise the better. I'm trying to work out what I need other than a PSU. Can anyone tell me if this speed controller will work?

Spindle: https://www.amazon.com/gp/product/B015HK2L90
Speed control: https://www.amazon.com/gp/product/B01MDV1HIL/
And here is the PSU I already have on hand: https://www.amazon.com/gp/product/B00D7CWSCG/

Thanks!

+Jerry Fountain OL from both DC+/- to spindle. And yes the sleeve, as I call it, over the case of the spindle is nonmetallic. Probably an uncertafied safety feature item to go along with the controller.
