You should be able to get a replacement part from Eckertech as they are the ones that sent you the bad part. And yes, the part is only about half printed.by Duaner - Huxley

I'm a retired marine carpenter. I had played around with electonics back in the 80's with a Radio Shack color computer that I hacked quite a bit and made things for. Started RepRap as something to fill some of my free time with and to keep the old brain working.by Duaner - General
My two cents worth. The Mendel (Sells) was first and the Prusa 'mendel' is a variation of that. If anything, the Prusa should be called as such ' The Prusa'. The Huxley was know as the mini Mendel in it's early development and now is known as the 'Huxley'. The Prusa is not 'The Mendel', it is a mendel variation.by Duaner - Developers

A grub screw is also called a set screw, it's a short screw with no head and just a slot for adjusting. The mudgard/fender washer has a larger outside diameter that a regular washer. A regular washer would be M8x16 I used 4" cable ties on my printer, they were plenty big for everything I needed.by Duaner - General Mendel Topics

I would think that it would depend on the rated voltage of your steppers. The ones I used for the x-y-z axis (NEMA 14's) are only rated 2.7 volts, but the NEMA 17 for my extruder is rated at 10 volts. I would feel ok running my NEMA 17 at 24 volts but not sure I'd go that much on the NEMA 14's. I'm using a 12 volt supply.by Duaner - Controllers
The wiki shows the stud-frame-end rods 60mm longer so the chassis plate (frog) needs to be that much longer also. The stud-frame-side rods are 70mm longer and I would think that some of that length should be added to the chassis plate so there is not to much overhang on the build plate. On my Huxley I added only 30mm to stud-frame-end rods and added that to the chassis plate so I would have a 140by Duaner - Huxley
FYI - what and were I used bearings on my Huxley 2 - 626 bearings are needed for the z-leadscrews 10 - 623's for x-carrage and 4 - 623's for x-belt 12 - 623's for y-bearing brackets and 4 - 623's for y-belt 10 - 623's for x-bearing clamps and 5 - 623's for z-belt You won't need to get 10 - 626'sby Duaner - Huxley
I used 45 - 623zz bearings and 2 - 626zz bearings in building my Huxleyby Duaner - Huxley
Not a problem for me now, but when I had my Huxley parts printed 6 months ago they were missing and had to be corrected. FYI your picture also only shows one each of the y-bearing-180 and y-bearing-360, there needs to be 4 of each. I'm just trying to help you get all the parts needed.by Duaner - Plastic RepRap Parts for Sale
by looking at the pictures of the set, it is missing the z-brackets. it won't work without them.by Duaner - Plastic RepRap Parts for Sale

The Polulu item #1209 stepper motor is a NEMA 14. It is what I used on my Mini Mendel. Phidgets.com has NEMA 17's at a good price, $14.65 US.by Duaner - Reprappers
I had this problem with my Mini-Mendel build. The notch in the 360 side of the z-leadscrew-base was a little off. I'll try to explane how I fixed it. My bars and leadscrews are straight. The 180 side was fine so used it to find what adjustments I needed for the 360 side. The rods and leadscrews all need to parallel to each other. Both side to side and front to back. Put the z-bar 360 side just aby Duaner - General Mendel Topics
Those are the parts I have, but haven't got that far with my Mini build to use them yet. Soon I hope.by Duaner - Plastic Extruder Working Group
It is not so much the side where the belt attaches to the x-carriage but the other side. The belt rubbs on the carriage and could cause wear over time. I have Urethane belts so they should hold up for a while. It's something I thought should be fixed. That slit won't work as it has bearings in it. The Mini-Mendel uses 623 bearings, not 608's. There smaller for a smaller machine.by Duaner - General New Machines Topics
I have been building a Mini-Mendel and have found a problem I can not fix. I do not have the software to make the corrections. The x-axis belt(red) runs though the x-carriage(blue). The guide bearings on both the x-blunt-plate and the x-motor-end-clamp need to be moved. From my measurements they need to be moved out 15mm on one side and 20mm on the other. Is there anyone that can do this so I canby Duaner - General New Machines Topics
Still putting it together. I got my missing parts yesterday so working on the x-axis now. I still need to make the thick-sheets and hook-up the electronics. Then start testing.by Duaner - Plastic RepRap Parts for Sale
Rustyspoon printed my Mini-Mendel parts and when I got them I found that the x-axis-clamps were missing. I emailed him that they were missing from my order and from his Thingiverse post. It wasn't tell last night, reading the forum, that I saw that you were using cyrozap's files to print and thought to check his and the other Thingiverse Mini-Mendel posts. I posted the error here but didn't thinkby Duaner - Plastic RepRap Parts for Sale
From your questions I don't think the Mini-Mendel is for you. It is a smaller version of the Mendel that is still in development. I only know of one that has been completed and prints. I chose to build a Mini-Mendel for the challenge of getting it to work. There is very little documentation for it or even less for building it. I would think that something like a Makerbot would be better. It comesby Duaner - General Mendel Topics
1) Could degradation in print quality over successive generations of machines from printed parts become a significant problem? If the printed parts was used as a patterns for successive parts there could be degradaton. As the parts are printed from a digital file, I see the only variation would be the the print quality of the indivigual machines. 2) Would the new parts in each generation of maby Duaner - General
