This Printer

I'm spoiled by MGN12 Linear Rails, and I wanted a bigger machine, so this is a CR-10 size with some extra in the Z (310 x 310 x 435). I refer to it as my AMBP (All Metal Big Printer).

It's literally a clone of my Mi3 with some exceptions/changes/improvements.

Instead of hanging the extruder directly under the X rail as with my Mi3, I chose the more conventional route and side mounted it.

As with the Mi3, it's 2040 all held together with M6 x 25 socket head capscrews, drilled, tapped and counterbored where needed to let the screws sit flush and recessed. The only additional frame support is the 2 Z braces that were printed by this printer. Weighing in at 48 lbs makes it a tank.

It's running Marlin 1.1.9 on RAMPS 1.6 with TMC 2208's. The Dual Z feature in Marlin is enabled so both Z screws get their own stepper driver and end stop switch. As with the Mi3, it got a pillow block bearing for each screw.

I have no need or desire for wireless: Wi-Fi bad (IMHO), nor do I care
