Both feet complete!
Added 2017-05-27 08:46:06 +0000 UTCSo tweaked and tested. Now running on dual Ninjaflex toothed belts (7mm width, 5mm pitch). This gives loads of torque and extra tension but won't be able to test in anger until I get the body assembled and some drive electronics. Think I'm going to get hold of a sabertooth controller to try it. I'll keep a log of the electronic journey but obviously there's loads of options on Astromech and the web. The drive is free and smooth, omniwheels seems to work well so overall fairly confident. The drive gears and belts are modular so if we hit any issues under load there's a few options but I'm hoping we won't have to! Exciting as we're close to movement! Foot shells next from a design perspective and battery boxes. Then all the greebles. Then onto the dome drive gear. Then we have a basic droid. In the future expect 2-3-2 mechanism, arm modules (motorized), lights. Servos and all that good stuff. All optional but compatible. It's a lot of work to get the basic droid, once complete customize should be easier. I've got a few custom domes which I'll release in the coming months :-) happy printing and Thank you especially to my Patreons without which the whole process would be much slower!

Cool. Good to know.
2017-06-02 12:49:32 +0000 UTCStill looking at the dome motor. Won't be using the same motor as it's not got anywhere near the same load.

2017-06-02 04:09:51 +0000 UTCWill you be using the same motor for the dome? Would like to buy them all at once if possible. Thanks
2017-06-01 16:21:55 +0000 UTCGive it a test. I haven't much experience with PLA, sorry. But I understand it's easy to glue. My main concern would be on its flex under stress if you're going for a mobile droid (ankles and legs mainly. )

2017-06-01 05:14:48 +0000 UTCWent ahead and order a spool. I'll see how strong it feels once I get started here. :)
2017-06-01 02:44:19 +0000 UTCI was looking at using eSun PLA+ for most of this. Do you think that would hold up well enough or should I look at going with abs?
2017-05-30 17:09:00 +0000 UTCI would estimate around 20 - 25 kg, mainly ABS with a little Ninjaflex and nylon (well under a reel).
