After a little research and another look at the gcode that is output by kisslicer, it is in fact true that the bed automates itself to the resolution chosen.

Im working on a way to not have to adjust the z screw once it has been zeroed out. So far I only get a dimensionally correct first layer by following what the above guide says and adjusting the screw to the positions shown.

So the good news is, the above works just fine. Im just looking for a better way. It might include setting the extrusion width wider than what is actually output by the nozzle.

For now, Im using the guide above, as the amount the bed levels itself at, just isnt enough without adjusting the screw.

Contact TAM they have kits available for upgrades if you don't have them.
Maybe small $$? If you're in San Mateo,CA... just roll up here and shake them down for a set. ; )

Guys, when you level the bed and do the four corner thing, how close the nozzle should be to the bed? I mean, should a paper sheet be able to move freely between both of them?

Thx!

Mileage varies man. Just see what works for you.

Mainly the difference is the tape you use, how thick that is, and how it may deform (become compacted) increasing that gap.

We typically seat our nozzle directly on the bed. So that it doesn't drag or score the tape while moving around but you cannot fit anything under it.
This assures that the first layer smooshes a bit and creates a nice solid surface on the back side of the model. Sometimes if it's too far away we don't get the smooshing and then we get very small gaps between the walls which could result in part failure depending on design.

Thanks LaserGnomes! I've just posted a picture of my first print on the "Projects" part of the forum. Will work on my bed leveling once my printer is fixed!!

A complete newbie here... (so new I won't have my printer until Christmas or so) but I am starting to worry my way through the manual and wonder about bed leveling.

I see that many users of other systems use a tool called a "dial test indicator", either analog or digital, to measure extremely fine variations in the bed level. Other users just use the "stick a piece of paper in 'til it just slides" method.

So my questions are:
(1) Is the "sliding paper" plenty accurate enough? If just "maybe",
(2) Can you use a "dial test indicator" on the newest upcoming TypeA system, and if so how much accuracy is too much?
(3) How would one attach such a gauge?

Thanks

A dial indicator is overkill,really all you need is a piece of paper and then run something big and watch how the first layer goes down.
You can dl and open this http://www.thingiverse.com/thing:34558 in SCAD and adjust it to fit perfectly in the bed .

Honestly, I too use the paper method...I use a thin business card and my desired resistance is enough so that it's pretty much free but I can just barely feel the nozzle as I slide it.
