I am selling my spare RAMPS 1.4 with 4x heatsinked stepstick drivers and Kliment's SD card reader. By saying RAMPS, I am noting that I am not selling just the shield but the Arduino board as well. The board is 100% functional and complete assembled. Prices: Arduino ATMEGA 1280 = $40 RAMPS Sheild = $70 4x Stepsticks w/ heat sink @$20 = $80 Kliment's microSD = $25 I paid over $225 for these paby WildBill - For Sale

Sorry, it will be soon. I'm relocating from MN to Houston Tx over the next few weeks and want to wait until I can fully support it.

Version1 can be placed right in front of my laptop while slicing and linux host while printing or in front of the printer for stand alone. mounting to frame adds extra flexing if you mess with it during a print I feel.by WildBill - Reprappers
My dual system is very different from my single, and very different from any existing solutions. It will not have a buda on it as that is a very tall hot end. I'm working to improve reprap not limit it. You are also correct that they say they base it on the MK7/8 on their gallery page.by WildBill - General
it is simple physics, I'll release modal results tomorrow for this system if you want to see what a frame will do when throwing that much mass around. There is no way two nema17, and all of that billet alum is lighter than a single nema17 and some printed ABS... That sounds far fetched to me. If they based it on the MK7/8 like they say and things are identical, I challenge you to prove it to meby WildBill - General

He is talking about kickstarter projects in general not delivering on promises. Like the promise that this system is compatible with a prusa frame or carriage. Oh or the promise that you will not lose out on print area or print height. Basically anyone can promise anything on kickstarter and get funding true or not is what spacexula is saying. This system will kill your x axis acceleration too, nby WildBill - General

An under powered motor is not high quality and the UP! system is not a good starting point for reprap improvement. You are undercutting a good company in the process anby WildBill - General
It is a poor design all together, the motor selection is wrong the spacing is huge the direction of nozzles is wrong, sure it will work fine on a replicator with space next to a bed or a bed moving in x and y but not only y. You added a ton of moving mass, and moving mass is a reprap's primary enemy. Your motors are limited on torque becaues a direct drive solution needs to be geared to get decenby WildBill - General
Horrible design for a dual extruder. sure lets use only 1/3 of the print bed and have leveling nozzle issues and print at a max speed of 30mm/s and be limited to 1.75mm filament oh and weigh the x axis down a ton... Smart... I feel sorry for you backers who are about to be dissapointed...by WildBill - General

Either motor from phidgets works fine, 1/16 microstepping on a 0.9* may be too much for your micro to handle unless you have something more powerful than an Arduino.by WildBill - Stepper Motors, Servo Motors, DC Motors
Printed y carriages introduce a ton of issues. Go with the holders!by WildBill - Reprappers
Kits are for sissies! Check my self sourcing links for best/cheapest components: I see a lot of people sourcing from more expensive places than I have on my list.by WildBill - Reprappers
I still feel that it boils down to personal ability, if you cannot assemble simple threaded rods then go buy a pre-built printer. If you need a pre-built printer, reprap is not for you. Basically if you don't have the ability to do basic assembly and programming you will never be able to utilise the reprap correctly. If reprap is too hard, get a Replicator, Mosiac, or another pre-built printer.by WildBill - Developers
Sounds good, I'll be looking for some sturdy work tables for the garage this weekend. I look forward to seeing other printers. I'll try and remember you have cat allergies. BEEER!by WildBill - Mankato Blue Earth County Minnesota RUG
If a prusa is prefered with the general public, I keep an up-to-date US sourcing notepad on titanpad.com @ for the cheapest sources I can find for items. May come in handy for other variants too.by WildBill - Mankato Blue Earth County Minnesota RUG
Yeah, good luck with your arduino based micro handling 1/16th on .9deg motors. Again this is not feasible with todays micros until we have ARM micros at around 100mhz.by WildBill - Reprappers
I figure that to print one of those knobs at your listed filament cost it would be $.07/ea @ 50% infill, I also recommend flipping the knob 180* and print on the other end.by WildBill - General
Until we have ARM micros you will never be able to use all of the steps at 1/16 stepping, you would be limited to 1/8 stepping.by WildBill - Reprappers
I agree, the indigogo should move forward. Reguarding the bearing, you can already purchase one off the shelf from vxb.com, they are known as 8mm u groove bearings and run about $12.95/ea. You may need to modify the idler to accomidate these bearings, they are 11mm wide x 24mm tall. I think 608zz is 7mm wide x 22mm tall.by WildBill - Reprappers
I'll be working on miniature direct drive dual extrusion for the next couple of weeks. After that it is back to printing full sets and working on new bots.
