I think a standard carriage would be perfect, especially if you want to try dual eventually.

My is done.

6mm blue acrylic carriage, natural ABS mounting block.

Has anyone calibrated the steps/mm on this thing yet to save me the trouble?

As far as calibration, not that I'm aware of. I've been stuck working the last few days due to some yucky outage issues. In other news, I'm jealous of your fabrication skills and toolset, but that's why I'm all about doing this 3D printer thing so super-thanks for sharing. :mrgreen:

Hey Bart
Can you put up the STL file for the extruder mount that you made.

Here is my STL file. I'll post the plate later.

Do you think there is any need for a fan blowing on the gear/shaft?

Any mount thoughts that cleanly integrate fan mounts for the j-head or material?

I've been wondering if you could make the mount in such a way that the fan could be the support for the shelf on the one side or maybe just have two fans as the legs supporting the shelf with a slower speed. It isn't fully worked out in my head, but I imagine the shelf would be sit flush between the fans since the j-head would be directly attached to the extruder. Maybe the shelf would be a box with no top and bottom turned on its side. Attach the box to the carriage plate from the back of the carriage plate since you wouldn't have room to mount it from the front and the screw the fans on either side.

Another thought, if the shelf was made of metal or something, it could sync heat off the stepper and into the path of the air flowing below providing some cooling. Maybe we should try to talk bdring into creating another extrusion just for this. ;)

Do you have any ideas how you'd think it could work?

EDIT: Actually, maybe we could just slide the fans into some square tubing with spacers between them. You could even cut the pipe at an angle maybe and reorient the one fan down with some spacers and my be some elastic pulling the fans together. I'm not sure that makes sense, but I have to get back to work.

I measured the steps per millimeter of the SeeMeCNC EzStuder at about 95.9 stes/mm

Theoretical value:

NEMA 17 (16 microsteps) : 200 * 16 = 3200 steps/rev
The "EZStruder - 70782 Drive Roller-1" has a "filament"-diameter of 11mm.

=> 3200 / (11 * 3.14) = 92.6 steps/mm
