I print with 100% extrusion multiplier and 100% first layer height for all my prints. Most important part is to dial in your initial z-gap or z-offset for the first layer. This is all dependent on the thickness of your business card or piece of paper you used to level your bed. Plug that value in as a negative value for z-offset. In my case z-offset is set to -0.25mm (the thickness of the business card I used to level my bed).

The initial gap you use for leveling doesn't need to be compensated for in Z height. Most of that initial gap is taken up by thermal expansion of the hotend. That is as long as you use a thin piece of paper. A business card is 3-4 as times as thick as a 20-24# paper.

Also, if you notch out a piece of these hinges (http://www.thingiverse.com/thing:1597284 not my design), you can simply slide the door to the right (or left, per your notches) in order to keep the door held up. I find this is way easier than the add-on door holders. A chisel makes this a quick mod ... or I suppose you could edit the print file.

That is an elegant solution! Do you ever accidentally knock the door causing it to close?

Good point. It has been easier for me to use a business card over a piece of paper, due to the rough texture of my build surface (buildtak on spring steel does not age well... bubbles everywhere)

Not really. If anything, I knock the whole thing off the QIDI since it's an open hinge design... but just once.

I've since managed to avoid doing that well enough. Version 2 of the hinge could just let the door separate at a specific angle, like 90 degrees. That would be a cool mod. That plus slide to keep open (could even bias the contacting faces of the notch so it prefers to "keep open", hopefully I'm explaining that well enough.) So many ideas, so little time...

Looking for a z axis shim, what are you guys using.

I like this one, but I have 8mm rods, so you may need a different version... It is around somewhere

I was just trying to print that one when it failed! I think I found one. Going to print now.

Did you make a cable chain thing for the gantry? What one did you find that worked well for this printer

Failed? Print it with the indents facing upward?
I am using the Maghold build plate with a combination steel sheet and 1/4" boro stackup, so I've adjusted the thickness of the Zaxis shim to be a little bit thinner than the 6.35mm version. PS: I couldn't find a 10mm version.

When ya want to upgrade to 10mm rods? I have 3 kits ready. Let me know what color the plastic, I have many ABS colors. :-)

I had the nozzle to close. Just did a cleaning.

I need to come up with a corner clip system for the glass.


Check out this shim, I just found it. http://www.thingiverse.com/thing:1670502
