getting good first layer adhesion - check
getting good layer adhesion without gaps or overfill - check with a little work to do on the blobs. Your extruder appears to be reasonably well calibrated and filament pressure correct.
no signs of backlash (i.e. parallel sides, plumb sides, layers stacked properly) - check

Now you can measure wall thickness, width and height and compare to your model and slicer settings - priceless (sorry, had to add that!)

do i really need to check that last line, or was that just being funny? seriously i dont know...lol

or just thickness of the wall?

I have used that to help calibrate x-y steps/mm by comparing the width and length to what it was supposed to be. Most often though the goal with that cube is to tweak single wall thickness. Try to get a good measurement of the wall thickness, one layer is best (be careful not to cut into it with calipers). Now compare that to what the g-code thought the layer thickness was. If they are close, tweak your extruder flow modifier in the slicer. If they are way off apply the change to your e-steps/mm.

Shoot down to "Slic3r/Skeinforge/Sfact settings".

Hope it helps.

Sorry, I was being serious and funny all at once! It is good to verify dimensions at this point.

can't get that link to work..edit: finally popped up

i'm noticing my extruder is getting loud, sounds like wood creaking ...hmmm

Egads foshon, that avatar scared the he!! out of me!

Mine also creaks. And sounds like a can full of rocks on retracts. My other printer has a direct drive extruder (bowden also) and is much, much quieter. I want to figure out how to get one on here and try it out.

I tried to post a youtube video but its scrambling the video for some reason.. grrr.

Mine has the same squeak. I haven't gotten a chance to try 3in1 Oil on the gears yet.

g.

I took the extruder apart and checked it nothing seems to be out of the ordinary, but at the same time while it was off, i sanded a bevel into the smaller gears near the filament roller, it seemed like it was rubbing against the bottom of the bowden adapter nut. I Put it all back together and the creaking noises went away. I can't be positive that's what caused it but might have been a combination of that and retorquing the assembly bolts. at least the noise is gone for now.

gabrielk had that issue too and he posted about shaving a bit of plastic to allow the knurled nut to thread a little higher up to avoid the gear

I saw that but i didn't want to sand that area down, i think its that length for a reason to help the filament from binding. I think beveling the gear is a better idea

I got a little ambitious last night. Since my calibration prints were coming out ok, I'd try something more useful. The spool holder, not perfect but still gonna be put to use. http://www.thingiverse.com/thing:60750

what infill pattern would you have used for the base of the spool holder and how do i get rid of the blobs.

The print looks pretty good.
On the base it just looks like you are extruding too much plastic.

do i just adjust flow rate, while its printing to reduce plastic? then change it back when the infill is done?

This is what I do to calibrate, print a single wall print adjust flow rate then verify with a 100% fill print.

thanks!

Make sure you only use that for its intended purposes.

Since i broke my lcd angle mount trying to take my defective seemecnc lcd off. I had to figure out an alternative way to mount it and still have access to the sd card slot.

here is my solution. Its not angled like I wanted but it works. SEEMECNC CAN I GET A REPLACEMENT ANGLE MOUNT, WITH MY REPLACEMENT LCD???

I have micheal, just getting a little impatient waiting for a response. by the way, you got any of those 25mm fans yet? I wanna get one for my hotend

Does anyone know if there is a fan output for cooling the rambo? I would like to get a fan to circulate air around my rambo board. I have the 1.1b board but the pictures on the wiki doesn't show this connector. its says fan-2 right next to it, so i'm assuming its for a rambo cooling fan or is it for a printing fan?(circled in red below)
edit: never mind, I think if found my answer i believe thats a cooling fan connector for cooling printed parts, not a connector for running a cooling fan for the rambo.
so i'll just run a cooling fan for the rambo off my 12v accessory fuse block.

Isn't there one on the lower right corner area of the board labelled 12v aux out?

your absolutely right, i just checked, but they didnt include any headers for it. darn. rather than remove this thing to solder in one connector i'll just use my fuse block.

I run mine directly off a spare 12V line from the PSU.
