Replicator 2X z-axis shim by taskman Mar 29, 2013

Description

I have a 5mm glass plate on top of my aluminium plate on the 2X. This shim will fix the problem with the extra height

I created two extra versions. Large adds 2mm on top of the normal and XLarge adds 4mm on top of the normal. XLarge should be high enough for a 9mm plate. I haven't printed Large and XLarge to test them

It's hard to see in the photo but I had to bend the upper arm of the rear clip down to keep it clear of the belt and rods. This makes it really difficult to open but it works.

The link in my replay got mangled, and the site didn't know who I was.
There's a photo with shim I derived from yours (http://www.thingiverse.com/thing:89281). The two clips you see are the only two clips I use. There's Kapton between the glass and aluminum which may be giving me extra friction.

Instructions

Open the back of the printer and place the shim on the back of the build platform as shown in the photos. Warning: there is a screw hidden behind the cabling at the back and it uses a different allen key than any other screws on the bot
How did you attach the glass plate to the HBP?
Silicone adhesive?
I'm only using two clips and they never get hit. One in the back, just to the right of center (to avoid the cutout for the wires) and one in the front, directly opposite the one in the back. Only a couple millimeters of each clip is actually grabbing the platform. With this setup all homing, parking during heating, and printing operations stay clear of the clips.

(I'm using Kapton between the aluminum, btw)
Can you upload a photo to flickr and show us please? My glass is the exact size of my aluminium and my clips holding the glass get hit when I create large items so I always have to move the clips around

Clamps that I bought from the office stationary shop, but it is painful. The clamps are always hit by the head at some point or they pop off. I am working on a new system. If my new system can get done and it works the build platform will also be much bigger.

Does the PLA grip and stuck to the glass?

You added a 6 mm glass on top, Why?
People recommended using glass because it is flat and using ABS/Acetone mix on glass makes ABS stick nicely. Also using glass + UHU glue stick make nylon stick nicely
