Anyone have a good Hbot recommendation? Thinking about building one…

2

Only “don’t build an H-bot, build a CoreXY instead”.

Have a look at @Wolfmanjm feed, there’s a corexy design on there somewhere.

Shane my friend, Crispen will be showing of a very nice H-bot he designed at the MRRF. I highly suggest you take a look at it. I am not sure of the details but the prototype he had at the last MRRF had some really great results.

Ah yeah I saw crispy1’s hbot last year. Very nice! :slight_smile:

@Whosa_whatsis : what CoreXY would you recommend?

http://wolfmanjm.github.io/wolfhbot/ works quite well now, not the easiest to build though. The Z was very challenging. Seeing @Eric Lien s one I think I should have used 2040 or 2060 on the frame instead of 2020. I think my Z is simpler though as it only uses one actuator/lead screw and a moving knot.

Have look at this page http://joshuavasquez.com/docs/jVasquez/Projects/coreXY.html

I am with @Whosa_whatsis , after building an h-bot I am going to change it to corexy.

Is there a “recommended” CoreXY bot implementation?

A fellow reprapper, @Luis_Macias_Acedo , did this one: https://www.dropbox.com/sh/ijmyg4h8875lfoi/3-NNLq96jC

I also noticed that @Eclsnowman has one he’s working on and bringing to MRRF. I’ll definitely check that one out this weekend. :slight_smile:

@Shane_Graber if you wanted something a little more adventurous, @David_Moorhouse was working on a alternate design that used pen-plotter mechanics. I think it stalled as a result of things and stuff but it looked very promising.

@Shane_Graber see you there. Also I am working on a design to ditch the 1/4 plate and use the corners of the extrusion as the support. This would improve the footprint to build size ratio and reduce the build difficulty/cost.
