Not sure how hacky you want to get, but I found that my E3V2Neo got significantly more accurate once I set up independent z control.
Unfortunately, the Mini SKR only has 4 stepper drivers, so I used my old 4.2.2 board in conjunction with the Mini SKR and klipper to enable z_tilt_adjust.
I had a ton of trouble (bed leveling) with the regular dual-z upgrade until then. It’s pretty easy to run another set of 24v wires to the old Creality board and I found a printable case to hold everything. Just make sure you use one board for both Z’s rather than splitting them across two boards to avoid latency.
I’m happy to post my klipper config if you want to try it.
Definitely agree. If you need to spin up a bunch of discrete VMs for labbing, that’s one thing, but noise, cooling, power consumption, and space all come into play for dedicated hardware. I host a variety of services and they all run on small, low energy hardware (which is often pretty cheap). I just spun up a matrix server on a $100 ebay HP ProDesk which has plenty of power (probably enough to deploy my whole stack).
