Re: Bed levelling on a Delta system, possible alternative?
Richard from google groups requested this. So here we go. Implementation of software endstop modification M666 (it is already pulled upstream) and implementation of G29 (single point probe) is here:...

Re: New arm design for Simpson style printer.
I bought a 4 foot driveway marker to use as a pulley shaft between the gear drives. $1.99 USD, fiberglass rod. If the O.D. is not an odd size, I will use a Nylon spacer or bushing as a pulley for the...

How would this design work as a CNC mill, if you were to use thick laser cut sheet metal for the frame and ?? for the arms? edit: Just saw the Dremel remark. I need one of these. :)

@A2 - do you have a build log anywhere? I have a large format Simpson in the cards and am a fan of the hardware store approach where possible, with possibly thin-walled steel extrusions or laser-cut...

I could use some help. I don't have access at the moment to a 3D printer, and want to build a Kossel. I've ordered all my electronics, (looking for motors now). I'd be happy to pay it forward when I'm...

Twine tensioner idea: This requires two holes in the arm, and two drywall screws. 1 Wrap the twine around the first drywall screw. This is your winch. 2 Pass the tag end of the twine through, and out...

A2: I am sure that is just a mockup but just in case I want to say that a herringbone like arrangement of the gears or some other alignment scheme is needed to keep the arms from shifting in the axial...

@A2 - I think I would just start a new thread for now, use it as a dumping ground, and then when you master the wiki you can copy/paste final solutions/designs there and a link back to the thread.

@Nicholas Correct, that model was thrown together in about 6 minutes :) I envision that a few crisscrossing of the string around the winching screw would anchor it to the screw so it wont slip during...

@pjoyce42: Sorry, all my development is in Autodesk Inventor. (I dream of there being a FOSS MCAD solution that can do the 10% of the functionality of Inventor or Solidworks that matters.) However, I...

I have to admit, I was wondering how you managed to make such amazing models in any of the FOSS MCAD suites. It makes a lot more sense now. I actually have Inventor (and the simulation suites (I love...

@jason.fisher I did a search for build log in the reprap wiki but I'm not seeing any thing. Maybe it has another name, most likely I just don't understand the wiki :) The word RepStrap came up in a...

I will look forward to trying this out, my plan, rightly or wrongly, will be to have a metallic bed base, and a probe ( A fixed pin with a connection back to the Ramps board) on the moving platform...
