Topic: First layers bigger
My printer after some troubles is printing, but the first layes of my printing are bigger, i tried to recalibrate the z axis but nothing. My extruder gear is tightened.

Can you clarify what you mean? Perhaps a photo?
For long prints using ABS the first layer will sometimes metal a bit, I've read that some people gradually lower the bed temp after the first half dozen layers are down. Printing a raft might help as well.
Re: First layers bigger
I have no decent camara to show the problem but maybe this draw can help, i'm printing a calibration cube of 1cmx1cmx1cm, and no matter the z level or the temperature it prints like in the drawing. sorry jeje the drawing is very simple

Your bed is too close to your nozzle. The trick in 3d printing is finding the sweet spot. Too close and you get your result. To far and you get bad adhesion and lifting.
Printing since 2009 and still love it!

Re: First layers bigger
I am experiencing the same thing....Ive tried calibrating the Z-axis but I am still getting the same results. Any suggestions?

It's not necessarily too close. Some people (me included) prefer the exteme squish because it ensures better adhesion. There is a trade off between giving your bottom layer a lip and losing some adhesive power. You have to decide which matters more to you. I don't mind the lip myself but I also haven't designed a part where it affected fit (yet).

This gear bearing really doesn't like a lip:

Preassembled moving parts are a favorite handout!
Also, lego compatible blocks don't clip together well with a lip.

I prefer to buy gears and bearings myself 
Re: First layers bigger
I really hate how the press erases all previous press adjustments. It makes coming back after having to shut down really annoying since everything goes back to defaults or is set back to zero -.-
On the next patch I hope they allow us to atleast save changes so i dont have to keep re-setting the print temps that seem to be working for me....along with all the slicer information.
Still having a slight lip but its getting better. I am now having more trouble with bed adhesion though

Try using RH as an alternative. It seems to have less of the issues of SP.
Re: First layers bigger
Can I calibrate the latest RH to run the press or do I need to use the SD RH version? Cause I dont exactly like the SD RH version but it does seem better then SP
Re: First layers bigger
The latest version RH, 1.06, works fine for me. It doesn't have an SD configuration burned in, so you have to set the bed size, etc. manually the first time. 1.06 is pretty stable compared to the SD version and has more features.

I use Cura, so I don't know how much this may help if you're using something else. In Cura, there's a place where you can adjust the filament flow rate. The manufacturing tolerances on filament can vary enough to affect print quality. As someone else noted, you may need to adjust the bed, but if that doesn't fix it, the next step would be to adjust the flow rate of your filament. Basically, you're extruding more material than needed to fill the space so it's squishing out the sides. On some filament I've used, I've had to adjust the flow rate down to 86% to get good prints. I suspect variations in nozzle holes may also affect flow rates from what is expected. Hope that helps.
