I'm Endlesshunt, born of the clan McCloud in the year of our Lord 1963. :) Sound dramatic....... NOT... Uhmm, also wrong history, nevermind, please ignore what I just said.
For me it is an Endlesshunt for new tech, new ideas, new knowledge, new ways to implement old knowledge and always for perfection.
I have used this handle since the early 80s. A time when the internet was known(or not, depending on your security clearance) as ARPANET inside the US DoD and we all thought that bulletin boards at 300bps was mind boggling tech.
You might have run into me on numerous forums and MMORPGs - Eve online, Ashran's Call 1 and 2, Anarchy Online, WOW, Rift, Aion, Entropia Universe, EverQuest I and II, LotRO, Star Trek Online, Guild Wars and currently Guild Wars 2 where I'm a member of Advanced Tactics(AT) guild.
Lately (last 10 years) I'm a systems integrator. I integrate ERP systems (SAP, JDEwards etc.) with a scanning solution (Kofax, Google it, a very interesting product suite) for Accounts Payable departments of large corporations. This system is also integrated into a CRM system to automatically handle any invoice queries with their vendors. A totally hands off process. Invoices with queries could keep a clerk busy from 8 to 24 hour to resolve a single invoice query. Now that it is automated the clerk spends 0 time on it. This first solution that I build took 3 and a half years and a couple of million South African Rands. It also won an international award for ground breaking technology. The client of this first system was invited as a keynote speaker at a large international financial conference to showcase this solution.
Since then I have implemented numerous AP solutions, two more that also won international awards. Nowadays it takes about 2 to 3 month to design, build and implement an average AP solution.
Well, enough about me. Now about my 3D Printer.
I have a Prusa i3 Hephestos clone that has broken some of the parts (should have gotten a real Hephestos and not a clone).
I started to redraw the broken parts with the idea to just repair them with some updates on those parts.
This has now grown into a full blown redesign of the whole printer with all the "I'd Like to haves" included into the redesign.
I still think that the standard Hephestos version of the Prusa i3 is one of the better updates out there but at the same time I also think that it can be improved even more.
I want to improve it's accuracy as much as I can. For this I have swapped the standard 1.8 degree motors for 0.9 degree ones.
I have also swapped the GT2 x 36T belt pulleys for 16 tooth ones. According to the Prusa calculator this should give me a 5 micron resolution on the X and Y axis.
For the 0.9 degree step size and the M5 x 0.8mm thread on the Z axis leadscrew the calculator gives me 50 steps (0.002mm per step) for a .1mm layer thickness. (8000 steps per mm)
I'm thinking to replace the leadscrew with a M5 x 0.5mm fine pitch which will give me 80 steps (0.00125mm per step) for 0.1mm layers (12800 steps per mm)
I also use the E3D V6 (the real one, not Chinese) hot end with all their nozzle sizes down to 0.25mm.
All of this should theoretically give me highly detailed prints (OK!! enough already!!, I know the prints are going to be slow. The small nozzles and thin layers will only be used when I need the detail.)
To support this potentially high resolution I now want to make the printer as stable and movement/wobble free as I can make it. That is now one of the main reasons for the redesign.
No doubt someone will come along right after I have finalized my design and improve it even further, but that is the whole idea of this community. I'm looking forward to see what the next person will do with it.
