On a ten foot tall machine, I am thinking some kind of chain or monster rack and pinion.

But the rack and pinion would limit the speed of the machine for sure.]]> Idolcrasher General Wed, 08 Aug 2012 15:04:26 -0400 https://reprap.org/forum/read.php?1,145471,146931#msg-146931 Re: DeltaBot Printers (Rostock) - Prusa Killer or Passing Fad?

Heck Ya!,

A reprap with "pick and place" capabilities would be the bomb!

I am thinking that the data and power lines for Extruder #2 and the "Picker" head could be interchangeable :)

The video description says that the vertical accuracy is "within 0.25mm". That's actually pretty bad. It's more than one layer height if you're trying to print fine detail, and being that much off vertically is not going to produce results competing with cartesian bots in quality...

It looks cool as hell, though.]]> ttsalo General Thu, 02 Aug 2012 07:06:43 -0400 https://reprap.org/forum/read.php?1,145471,145881#msg-145881 Re: DeltaBot Printers (Rostock) - Prusa Killer or Passing Fad?

Any reason to think the print quality would take a serious dive? The belts will be fairly tense regardless...

Don't the rods simply serve as a guide?

My biggest question is stability of the platform in motion, seems to me that slop in the build could manifest in not very obvious ways, making debugging difficult.

You're completely right about Prusa development, its tough to follow, the only practical way is to get on the irc reprap channel. Search Google for a sneak peek of i3 though.

The Rostock alters its steps/mm depending on its position and is not linear like standard CNC machines. I see this being hard to calibrate but may be wrong, I think you may be able to just calibrate the z height, providing your bars are all exactly the same length (not much room for error!)]]> yydoctt General Wed, 01 Aug 2012 04:50:01 -0400 https://reprap.org/forum/read.php?1,145471,145588#msg-145588 Re: DeltaBot Printers (Rostock) - Prusa Killer or Passing Fad?

All Valid Points,

I am a little bummed that progress with the "Prusa" is not that easy to follow. I think that the average joe does not know that the Prusa us actually on V2 as we speak. I wish the RepRap Wiki made some distinction, showing that we are currently on Prusa V2.

I will surely make some observational posts on about the Rostock once I have one built. I too wonder about tuning the machine; reports/posts I have read are super optimistic about it not being all too difficult; we shall see.

I think I would argue that 1 printer can satisfy all needs; that time has simply not come yet. Once the RepRaps actually start approaching self replication, you can use that printer to make the printer that fits your needs ;)]]> Idolcrasher General Tue, 31 Jul 2012 14:28:08 -0400 https://reprap.org/forum/read.php?1,145471,145587#msg-145587 Re: DeltaBot Printers (Rostock) - Prusa Killer or Passing Fad?

The Rostock is a snazzy "unconventional" RepRap printer, with a stationary build bed and no threaded rods. Instead, it uses 3 pulley/belt controlled arms to position it's hot end anywhere in 3D space; FAST!

A huge number of people have "liked" the Rostock design on Thingiverse, to include the RepRap "All Father" himself: Adrian Bowyer.
