Not sure if the printer or its price is good but just saw this one: http://store.solidoodle.com/index.php?route=product/product&product_id=56
The price is good sharky,  but they don't say it's built with linear bearings, which is important to me.
Plus I think they are closed source.
That page claims the printer uses Arduino-based Sanguinololu electronics so it could use open source firmware.

Alright, I'm done with the build of the 3d printer, all I need to do now is to repair my laptop then download and install all the software and calibrate the machine, and of course hope everything works, here is the video of my finished printer.

Hi Nate,need to see if you can help, I am trying  to upload sprinter to the Arduino on my new printer, it stops at the"sd 2card.cpp"  please look at the photo, have any ideas as to what I should do at this point. This is why I have not updated my other printer to newer software, always problems. Thanks Jeff.:D

Hmm, last time I had problems like this, I had the arduino program set for the Uno model and not the Mega.  I selected Mega and everything cleared up.
  I noticed there is a new version of the Mega, wonder if there is any difference?

I do have mega selected, com 3 and drivers installed, I'll try reinstalling the drivers, see what happens, thanks.

Ok Nate, got my new printer up and  and running :cool::D:P. I just used the older software I had running on my first printer. It's not the newest versions but it works. I would like to update to the newer versions but couldn't get to first base on it, oh well.:D

Cool deal Jeff, I haven't updated my firmware since I started either.  I wish I could get to it, this summer is getting crazy.  I'm in the middle of getting permits and stuff for a property line fence.:rolleyes:  Someone is a bit too nosey and/or completly psyco next door.  

Have you got the SD board plugged in when your trying the new version?

I tried it both ways, with and without the sd board, same thing, I think their is something new in sprinter for the sd and I can't find what it is. How is your printer coming along, have you made any progress on it?

Say Nate, I found a power supply that will run the 3d printer electronics, steppers, hotend and heated bed plate all at once. Has 3.3 volts and 12 volts dc, 57 amps. It's awesome, my heated bed pulls 16 amps, this power supply has plenty left over for everything else. Has it's own cooling fan, changes rpm according to amp load. You can buy them used on ebay for, are you ready:cool::D:P:D:D:D:D:D:D:D  :D:D:D
Between $16 to $24, I bought two, payed $29 with shipping. Here is the link

Nate I went a little further on the hacking end of it, see photos. I made a circuit board to plug into the pins, mounted an on off switch in the board connected to pins a1 and b1, this enables you to power the power supply on and off. Have any questions, I have more data.

Okay Jeff, question for you...   Now that I have this Probotix CNC mill and controller, wouldn't be a fairly straightforward conversion to remove the router and replace it will an extruder?  The CNC USB controller already understands G-Code, so all I should need is to change software to build instead of cut correct?  I could use my 4th axis output to drive the extruder, I think.  Am I missing something?

Hi dog-one, yes in theory you are very correct . I don't remember how many steppers move the three axes XYZ, I think it's one for each. If the 4th axis is not being used, you would need to go into the software and see if you can activate the 4th axis and also have calibration perimeters, speed and direction, also is there a 4th driver board for the stepper and of course the 4th stepper motor. Next thing would be to have some way to control the temperature of the heated bed and the extruder. Also a way to hold a 15 lb. spool of filament above the extruder. One word of caution though, if in fact there is a driver board installed already and not being used,  do not activate it unless you have a stepper connected to it correctly, otherwise you will blow the board.
 There is a friend of mine who just joined the forum, who has built a cnc router from scratch and who recently built my 3d printer [with a little different twist, called the Prusa air], to do upgrades to his router machine and lathe. Now he's building a printer for his son. He is very knowledgeable as well, here is his YT channel.
https://www.youtube.com/user/ricochetproducts
He made the frame of the prusa air with his cnc router [files for g-code can be downloaded from thingiverse.com for free], then used my plastic parts kit to build the printer, here's a video he made of it printing, just want to make it very clear though, in no way is this a sales pitch, it's merely just to show what you could do with your router. Here is the wiki page for it and what Joe Prusa say's about it I do not believe, especially when the frame is made from plywood. Here is an improved version on thingiverse.com, http://www.thingiverse.com/thing:14204

Well hope this helps dog-one. :cool::D:P

Nate, I have been told from a very good source that instead of using kapton tape you can use finial net hair spray on the glass, works very well, I have not tried it yet though, I think it would work.:cool::D:P

Hey Jeff,
Would you have a link to the 4 bearing X carriage your using?  I'm only finding 3 bearing versions like this:
http://www.thingiverse.com/thing:30670

I’m finally having some success with printing ABS.  I was down to one working printer and I tried to print an ABS extruder, when my PLA X carriage melted! lol Ooops I forgot I made it out of PLA.  So now I just finished building a "RepStrap" X carriage out of extruded aluminium stock.  It works really well so far.

Too you should print out the wades hinged extruder, it's stronger and much easier to change the filament. Use the body of this one.

Use the hinge part of this one.

Nate the carriage will not need any bolts or nuts, the plastic fits tight enough around the LM8uu bearings to hold them well enough. If you do use bolts or zip ties just be careful the plastic is weak and the flanges will break off.
