@ Nophead's new machine : Looks nice. I wonder if maybe you put the vertical MDF braces on the outer edge and facing the other way you could make it "easy" to detach the vertical assembly from the base, and place it face down on the base making a self contained box for traveling.by bryanandaimee - General

There is now a wiki page with details on the standard and a contest has begun for those who might want to design for the standard.by bryanandaimee - Reprappers
And it's on like donkey kong! There are now 4 contestants so the contest carries. Deadline to enter is Oct 12.by bryanandaimee - Developers
And then there were four! Thanks to all those who entered. The contest is on! Still time for the rest of you to enter till Oct 12.by bryanandaimee - General
I agree on the whole, but I don't know that you can't have both. It seems like there is still room for reduced print designs that don't compromise on stiffness/strength. It may be that this particular design branch does need thicker smooth rod, but that may still be an overall win if the print times are significantly reduced (depending on the value of your time, $, and complexity multipliers) , aby bryanandaimee - Developers
No default! I'm expecting about 250,000 contestants to enter any minute now.by bryanandaimee - General
Actually the printing time is the main reason for me since that is the primary design goal of my test tube mendel. That and elimination of the fragile Z smooth rod bushing tower of the Prusa design. I have broken more than one of those and had to glue it back together. Others have gone the vertical route for their own reasons. There were enough projects adopting that configuration that I thoughtby bryanandaimee - Developers
hopefully, better stiffness around the x axis, smaller parts/shorter printing time, easier tool changes, integrated carriage-extruder designs to name a few. Seems like the vertical X axis could still distribute the weight to both smooth rod too. Don't see why it couldn't unless the bearings/bushings were spaced wrong.by bryanandaimee - Developers
So I went and stuck my foot in it. I have organized a contest to encourage designers to tweak existing projects and/or design new parts to the new vertical X axis standard. The contest page is here . Those wishing to participate must declare their intent by Oct 12. The contest will run to Nov 12 if enough entrants declare by Oct 12. Any and all publicity/blog posts etc. would be appreciated.by bryanandaimee - Developers

Created a wiki page here . Please update it with your project if you intend to adopt the standard, or just post a quick "count me in" here and I'll put your project in the Standards Compliant Projects section.by bryanandaimee - Developers

Because by and large, RepRap suppliers are not business men they are hobbyists. The RepRap community seems to have a pretty high tolerance level, as long as the product is good and the supplier seems to be doing their best and is an active member of the community. If there are quality control issues on top of everything else, then the tolerance level is significantly lower. No one would gripe thoby bryanandaimee - General
I have been a project gutenberg fan since the early 90's when I discovered it online while in high school. I had no idea he was also involved in RepRap. Shows how much I know. I think it's time I donated to gutengerg.org. So long, and thanks for all the booksby bryanandaimee - General

Just in case there are any affected tinkerers that don't often read the developers forum, there is a standard forming for those who wish to create interoperable X axis assemblies that are oriented vertically rather than horizontally as in Mendel and Prusa. Current rough draft is 70 mm center to center for the smooth rod and 30 mm center to center for the Z smooth and threaded rods. Please use thby bryanandaimee - Reprappers

I just refinished my deck with some stuff from home depot called Deck Restore. It's a very thick acrylic paint with sand or something in it. Comes in 4 gal buckets. You might be able to do something similar with an exterior acrylic or epoxy type paint and add some sand.by bryanandaimee - General
On windows, linux or mac?by bryanandaimee - Reprappers
I'm tempted to organize a contest myself, especially after I waxed eloquent a few months back about how to do it right. See post here . I'll give it some thought. As for the proper page for it, I think there is a reprap wiki page on standards. I don't know if there are any actual proposed standards in it yet or not. As for promotion, if I decide to do a contest, you'll see promotion, I can guaraby bryanandaimee - Developers
OK, so in hopes of getting decision-by-committee finalized in some reasonable time frame (is that possible?, I'll declare the sense of the discussion to be that a good standard would be 70 mm x smooth rod center to center and 30 mm z smooth to threaded rod center to center. This should ensure that any vertical x axis assembly/x carriage design will play at least sorta nice with other conformingby bryanandaimee - Developers

OK, I can see that there would be a need for wider spacing for those using LM8UU bearings. Would 70 work or should we allow more space for belt routing?by bryanandaimee - Developers
OK, I thought I was going crazy for a second, but I finally caught on that some of the discussion is on the threaded z rod to smooth z rod now. That seems like it might be another dimension that might benefit from some sort of standard. If Prusa and Sells mendel are both the same there's probably no reason to change. I vote for 60mm on the vertical smooth x bars and 30 mm on the z axis smooth toby bryanandaimee - Developers
I can see two explanations. He may be overworked and finding out that he charged too little and will therefore get pennies for his time, and is therefore hypersensitive to suggestions that he is pulling one over on his customers. This seems to be a common ailment in the community. Products are over promised and under priced and then when demand is more than the seller can handle, delays pop up aby bryanandaimee - General
Yes, I agree there are a lot of features of vertical x axis designs that seem to be an improvement. In addition to your excellent reasoning, I think the printed parts can be smaller and at the same time produce a stiffer assembly. I think it should be possible to shave an hour or two or possibly even more off the total print time of the x assembly and carriage/extruder if the extruder has an inteby bryanandaimee - Developers
I think there are a few hardware standards that could benefit designers in the short term. First, a good standard for hot end compatibility with extruder designs. Not every designer has the money to try all popular hot ends on their new extruder design, and not all hot end designers want to print out all the current carriage and extruder designs to test their hot ends on. A couple of dimensions aby bryanandaimee - Developers
