They sent me some samples when I was considering buying one. The part did still have a rough finish but for a prototype was very impressive. Still on my long listby Magnum - Reprappers

I guess i do not understand that. There is already a hole there that is slightly larger. I don't understand why you would need to printby Magnum - General
Thanks for the info...I suspected it might just be the file but all of the others so far look correct.by Magnum - General
When I built my liquid cooled PC I used a connector like this to supply power to the components while not powering the motherboard. Very useful for testing the pump and system for leaks. I have not looked into the pinout requirements for a reprap but looks like this might work as well? Bypass Adapterby Magnum - General
I just downloaded the 3D files for the wade extruder. Looking at the extruder block there is no hole in the side for the gear bolt to pass through. Just curious as to why that is not in the model, I haven't seen anything in the build instructions (yet) that indicate it must be drilled out? Since the bolt is captive in the bearings I don't see why this can't be made open. Am I just overlooking sby Magnum - General
I have recently switched to Alibre as well as Rhino3D as mentioned above. you did not mention how much you were willing to spend, but both are relatively cheap.by Magnum - General
yea, I think I may order these unless someone sees a major problem. I haven't looked at the gecko specs yet, but it may not matter if it has a connector, I may have to replace it anyway.... I would rather have more torque, just incase I want to do replaceable heads later.by Magnum - General
I looked at this page for the Lin Engineering Stepping motors from Alltronics. The part numbers listed must have changed. Looking at the site I found these motors and wanted to make sure I am comparing the same motors.As I have stated in another post I have ordered a Isaac and looking to get parts in. So looks like the build is on now, no turning back.by Magnum - General

I can say for me I am looking to build a mendel from the plans, but see no reason to implement some of the upgrades and changes others may have found along the way. Speaking of the builds, does anyone know if there are actual complete CAD assembly files of the Prusa?by Magnum - General
Normally when I think of a lead screw, I think of the type you have posted. I know my CNC pushes a lot weight around with a simple lead screw. Myself I think the installation would be easier than the belt.

DOH! You mean the third Reprap option! Found it now thanks.by Magnum - General
I have read some on the Prusja, but don't see the info right now but will check into it. Was really just thinking out load, but the more I read the more I can tell that belt drives may be faster anyway.by Magnum - General
Thanks... I have no carpet in my house.... Allergies.. Only wood and concrete for me...by Magnum - General
@Capo Nice stash.... hopefully I can come away with that much. Will depend on how long my friend wants to stay and tear down printers. But I forgot about the rods, should be able to use them as well.by Magnum - General

@xchristopherx Thanks for the info... I have a 2-ton press that will either pull the pulley off or separate the shaft from the motor Thanks for the tip on alltronics. I am in Arespace/Defense so I was thinking of stepping motors in the $50 each range....by Magnum - General
@Cefiar Thanks. I had read up on the number of wires (I am actually digging around the site some). The Gecko does not work with odd wired motors and from what they say are considered older motors. I am hoping that these being newer style printers they may have newer motors as well. I need to look up the difference in a restrap and a reprap.....by Magnum - General
Thanks... I should also point out I am not worried about the physical size. I have no parts made yet so adjusting for the bracket is not a problem. I am hoping they are NEMA 17 or larger. Guess best way to find out is to get one and spec it out.by Magnum - General
I have a friend who works at a local copier sales/repair center. When he heard I was looking into a reprap and what it can do he told me that they had several printers being set aside for disposal. They are perfectly good for parts such as grabbing the stepping motors and such. He said he would open up Sunday and I can come in and he would help me disassemble and get what I need.

Are you still using the belt drive. Just curious if faster speeds are possible if you used a lead screw type system.by Magnum - General
250 IPM would probably shake everything apart unless you make it out of some heavy material. Even my CNC only pushes 60-90 but that is about all the rapids you need when making one off parts like I do. The time on part is the largest time. Good to know though, I may go ahead and buy one. I do want to look more at the electronics, I don't want to do a lot of soldering so would prefer off the shelfby Magnum - General
Thanks, I did find it listed as verified working so that made me feel a little better, good to know someone else is using them without problems. They are highly recommended for DIY CNC machines, so I definitely want to go that route.by Magnum - General
@Anthong Redbeard Thanks for the info. After posting I realized I kinda left my questions wide open. I have been reading and finding that the key is in the extruder as well as the accuracy of the parts made as you mention for linear bearings and such. I have also looked at the U print and the Z corp printers and while I could use them I think the cost and price of material would not be cost effeby Magnum - General
I am new to the forums and reprap in general. I am getting involved in rapid prototyping and decided a while back to invest in CNC machines/lathes for also supporting small production runs if needed. However I need a 3D printer and I don;t really want to invest another 30-40K in a professional one.
