Further progress; changed rod diameters to 10mm outer support/drive shafts and 8mm x/y shafts. Also moved the hot ends together on the carriage. also also added spectra braid.
What dimensions are you aiming for? 300^3 mm?
@ThantiK Yeps, in that region (exact dimensions dependant on the final extruder design). BTW, Calculated 24 wraps of spectra as opposed to the original 10. Not too bad when it’s only 0.6 mm diameter. Correction, more like 20, bad maths.
Very interesting. I’m going to have to see how much t-slot is going for now.
$85 us for 6m including shipping from China; just about to order some 
Humm thats really not to bad at all.
I’d build one. Is it open source?
@matthew_bennett Certainly will be - It’s a derivative of the T-Slot Tantillus design found here (https://github.com/goopyplastic/tslot-tantillus) which in turn is a Tantillus derivative (https://github.com/Intrinsically-Sublime/Tantillus). I’d be hesitant to release any source files until I’ve proven it to work, there are quite a few design deviations from the original that may or may not pan out. In saying that, if you’re feeling adventurous, I’ll put the STLs up on Github.
@Tim_Rastall release early, release often - there are way too many projects out there that promised to release their files at some point but never did.
@Thomas_Sanladerer Yes, agree. However, that philosophy needs to be tempered with a bit of quality control IMO. Plenty of projects out there that are effectively useless due to some fundamental flaw that was never identified due to poor QA, you see that often enough on Thingiverse with non-manifold stls etc. In saying that, once I’m happy with the design, I’ll stick the source files on Github with an appropriate ‘untested’ disclaimer.
