noob at eagle, would like you to check i'm not about to fail

Hi,
Apologise if this is not the right forum, i’d like to have seeed make a pcb, but i’m very new to eagle and have never made a pcb so was wondering if anyone could see any glaring errors

in eagle, I’m using Seeeds design rules
I get stop mask errors, but if i turn off the layers i don’t want, i don’t’ get any errors; is that ok?

My design will fit on a 10x10cm board, but i think my board size in eagle is bigger, i don’t know how to correct that, does it matter?

What board thickness should i use? i intend to screw it to something, it’s a clock, so it should get moved about too much

I’m unable to ascertain if my design exceeds the tolerances that seeed can produce, i get no design errors (except as above). But seed state that the min solder mask clearance width is 0.13 and i think my design has tracks that are very close to a couple of pads (but i don’t know how to measure the gap in mm)

Seed says i should provide
Top Layer: pcbname.GTL
Bottom Layer: pcbname.GBL
Solder Mask Top: pcbname.GTS
Solder Mask Bottom: pcbname.GBS
Silk Top: pcbname.GTO
Silk Bottom: pcbname.GBO
Drill Drawing: pcbname.TXT

but i’m only making a single sided board and i don’t have a silk bottom (i think).

I’m using the Seeed_Gerber_Generater_v0r95_DrillAlign.cam file to make the cam files, i’m assuming this is correct but i don’t know what i’m doing.

I’ve uploaded the files i would submit here, a few others on the forum suggest i view the gerber files, but i don’t know what i’m looking for or at.

hi there,
1.

please ingore the errors about stop mask layer.

please update your eagle version(6.4)

maybe 1.6mm PCB thickness can meet your requirement
4.if there is something wrong with your gerber files, we will contact with you, so please don’t worry about it.
