Tilt printer
Description
Thought's:
Print onto ABP with stepper as the Z axis, and canter the Y axis at 45deg which may allow very long prints. (STL's will have to be rotated to 45deg in skeinforge)
Objective:
A bot that can print bigger than itself.
Update 25 Sept 2011, Bot final dimensions 420mm Long x 210mm High x 198mm wide - Print Size 50mm High 215mm Wide.... errr and very long (hopefully)
Instructions
Attached is picture of the mk1, trying to export the simpler mk3 files at the moment but Alibre not behaving. (possibly im a bit drunk),
Update 25 Sept 2011- Still drunk (now MK7 looking good and has a name)
Sorted parallelism problems whent to rack an pinion system. Sorted slop on rack and pinion by positive tension between pinion and rack. XY axis now work well, although noisy. Also need adjustable mechanical end stop Y axis to stop print head burrying into print bed when motor turns off.
Belt no good, Size wrong 40mm former pipe ended up with belt wider than expected and thus tension system failed. Replacement of belt requires removal of front panel and hole belt system, also leveling currently wrong it needs tripod adjustment not just left and right but the front as well. Current design missing racers ether side of belt driven side to support long prints using printed support material.
Will try to sort, may even get the tool head channge to work as left space on right side of box for additional heads and the stepper is not part of the tool head, but thats for the future.

I'm curious, how is this thing working? Have you managed to overcome the fundimental problem of belt/tension based ABP's?
The APB was planned to be aluminium 220mm x 40mm x 2mm stock with solid 6mm rods for rollers and sleaved with heat shrink, it is built with compression springs left and right pushing the none drive roller into the belt.
But I miss calculated the travel required when I found the pipe was not 38mm diameter but 40mm, so at the moment belt does not work.
To tell truth not worried about warping as in this application the belt continuosly moves and is not static as in normal ABP's.
releasing files tho stuk in japan case needs some changes and build platform is having full redesign expect to finish this 2 or 3 months
The duel thread design does not work with nema17 gen 3 electronics it constantly skips, am working on it :(
Cool! Did you get the idea from my post on reprap-dev suggesting this ( http://reprap.org/pipermail/re... ), or did you come up with the same idea independently?
ok, maybe I am just not engineer material. What is the advantage of the 45 degree angle? I cant picture it.
Sorry mate, I dont visit the reprap.dev pages often, if ever.
Got the idea in January about the last time I posted a design here, have been working on it since then, thus the mk1 and mk3 designs, problem I have now is the printer is down so decided to post what I got.
It originated from the frustration of high prints toppling over. At the time sat back and
tried to think what was wrong, then realised my normal printer only has one moving axis in it.
From that thought I realised only 2 moving axis were needed when combined with ABP.
Has anyone tried this, or is it a waist of time.
This is combination with Reprap 1X2's conveyor belt would be very interesting:

I'm always looking for ways to get rid of the solid smooth rods on Mendel (they're too expensive compared to other ferro vitamin parts, like the threaded rods for example.)
Very cool. I'm currently building a printer using aluminum extrusion + printed blocks too. I'm really liking it.
Yeh when I was constructing the RepRap Filament Spindle by tbuser, I found all with all the rods construction very unstable until every thing was tight, that but me off making a Huxley.
Extruded aluminium seems much more rigid when slotted into the printed blocks before tightening.

Ruttmeister was right for me ABP doesnt work.
Whosawhatsis is right for another way, but im not guna shuv a board in per print.
Rack and pinion (printed) doesnt work (sucks actually)...
generates to much vibration even with 1/16 stepppin
Are well at moment neeeded larger build area .. thus Huxley interest... think I have solved above with (got name before bot)
iTilt2 jr - its different (but based onsame old)
