Hi Folks,
Finally got the time to finish my Max v2; completely standard build except for an EVGA 500W PSU and some heavy gauge silicone wires for the Bed.
Really liking this printer so far but have found calibration to be somewhat painful. Kept running out of adjustment on the 10mm end stop screws.
I did get it close enough to print fairly well but couldn't get the last tower to level fully.
I've since used OpenDACT to recalibrate and have it within 0.1mm now.
New issue!
The low layers of the builds flare out. Hard to explain but pic is linked here:

This is a 20mm hollow cube i've been using for calibration - no infill
The sides are right on 20.05mm but the first layer is 20.89 and over about 5-8 layers it reduces down to 20.05.
First layer height is 0.20
standard layer 0.25
Z height is also slightly out at 19.45mm
Any thoughts on what i've managed to change that caused this?

Re: First layer dimensions after calibration
Here's two handy guides for troubleshooting print problems visually. I find it really useful when I'm trying to troubleshoot an issue as it gives the problems names that you can google for

This is called 'elephant footing' - however looking at your first layer it looks a little wobbly around the edges, which could mean either it isn't sticking properly to the bed and is lifting, or it's being pushed into the bed too much, and the pressure in the nozzle is resulting in the filament coming out in blobs.
Also why do you have your first layer set smaller than the rest? Generally the first layer should be the same size or thicker than your subsequent layers.
What size nozzle are you running? What temps? PLA or ABS?
Of course I'm still a noob so take my advice with a grain of salt!

Smoke me a kipper, I'll be back for breakfast.
Re: First layer dimensions after calibration
Excellent guides, those are exacylty what i need. Thanks!
I'll have a play with the layer thickness and extrusion. It wasnt doing this all all originally; but it does stick perfectly to the bed right now.
