Seeking advice on a simple inexpensive 3d printer "spindle"

The more I read on this, the more I feel I have to learn.

Sent you a PM.

I may have a solution for the qubd coming very soon. Initial testing show track marks similiar to my own setup and feed quality that looks very promising

Again thanks for all the responses. I have put this on the back burner for now, but an cheap temp controller would be the Velleman MK138. (under $10). It is the same controller that was used on the seemecnc H-1 (http://reprap.org/wiki/Seemecnc_h1)

You can purchase as a kit many places including:

Good post explaining how it works

Thanks for the links! I've got an extruder on its way from kbot3d, so looking forward to experimenting w/ this.

good find on the temp controller. I have a ta4 pid controller but will be buying two of these to experiment with. I will be printing a full size guitar body for a customer and plan to convert my shap eoko for the project. that and the wife had given me the go ahead to build a much larger nicer shapeoko style mill for cabinet work

The Shapeoko frame itself isn't quite perfect for a high-res 3d printer. In particular, the Z-axis Makerslide is weighted on the top & bottom by the motor & extruder. Unless you've done a truly amazing job stabilizing or just run slowly, this will bounce a little bit during sharp Y movement. Usually that won't be a big deal but it was enough to wreck some of my prints & cause wavy lines in others. I've pretty much abandoned by Qu-bd, and am going to try an extruder setup from SeeMeCNC, this time on a Reprap frame I picked up on eBay.

Are you still looking for a solution to this project? If so I have THE answer.

Get this:
$35
http://shop.seemecnc.com/EZStruder-Cold ... -70780.htm

`$65
Then get a Hot end, do your own research as to what you might think you want. I use Makergear's Hot ends, they're decent.
~$20
Then get a Nema 17 bi-polar 2A from anywhere that will sell it for under $20 Shipped
~$50-$200
Then get a RAMPS 1.4 board with an Arduino MEGA 2560

If you get this far, reply back and I'll continue with the rest of the steps
