This is a great mod I think, I am yet to get the z dialled in correctly, I think its closer to 0.25mm or so, raft seems to be sticking quite well though and comes off easily.
I have only printed a couple of smallish cross sections so far though.

I forgot to measure the z screw, can someone tell me the diameter and length so I can get a longer one, mine's basically bottomed out already from the factory.  I'm guessing it's M3 by about 20mm?


Although im not using using a glass bed but going to try with ceramic, i need a slightly longer z screw, is an m3 20mm about right?

The spacers that come with motherboards are ideal, they just screw onto the bottom of the original screw and add about 5mm in length.

Got a 12x12 mirror that was used at my wedding as a centerpiece.  Think I'm going to sacrifice it to get what I need.  Should yield 4 6x6 pieces that should do pretty good.

How is the weather in Southern Texas?

After using the glass plate I would never go back to the stock kapton taped bed.  It works fantastic.... prints are nice an flat.

Completely agree. Best $4 I've spent.

Get two glass plates, so you can easily swap on and off!

would a thin silicon sheet between the glass and aluminium/kapton suffice to grip it ?
It would be nice if it could be used with no clips at all.

The Silicon might singe a bit with the heat. I'd hate to smell that.

I had a print with a few STLs on one plate that were big enough that I had to move the clips around to keep them out of the way, but most of the time its fine.

I am just lightly misting the glass with the hairspray.... will try sandblasting the glass tomorrow to see if I can eliminate the hairspray completely.


Ian,  What do you do about the glass clips with Lawsy's new firmware?  I just saw his vid and it shows homing x, y and z (the back right corner) and then it rapids to the front left corner while it waits to get to temp.  I like clipping the glass in the corners as that seems to most appropriate place to contribute to flatness but rapids at with Z near the bed sound dangerous to me.

Are you using hairspray?
What temps are you running? First layer & entire print

What seems to work best? Light spray of hairspray or fairly liberal?

****CAUTION: ****  I got lucky and dodged a potential crash - I noticed this a second before I started a print!!  Since the clips I used for the glass are above "Z" zero you have to make sure that your "Z" is ABOVE the tops of the clips when you start a print.  When you start the SD, it homes X and Y first and then starts moving Z.  If your nozzle is not high enough above the bed you will crash and it could be ugly.
