Has anyone here changed the Biqu B1 SKR v1.4 mainboard to SKR MINI E3 V3?
Well. Why would you want to do that?
In the end, choose the board that has the features you need. Software is the same anyway.
With Klipper you can even combine multiple boards to get the features you want.
Suspected that the SKR v1.4 original motherboard died (Hotend not heating), so advanced to the SKR MINI v3 + a Raspberry PI for Klipper.
I’m looking for “printer.cfg” that matches this setup…
The printer.cfg is highly dependent on your setup. For reference you can look at the example config for the SKR mini e3 v3: github.com/…/generic-bigtreetech-skr-mini-e3-v3.0…

Looking closer on the X, Y, Z and E ports i observe that the ports are labeled different on the two cards.
Old SKR v1.4: Square pin = 1B, next pin = 1A, next = 2A, and last is 2B. Also the order is EN | STOP | DIR
New SKR MINI: Square pin = 2B, next pin = 1B, next = 1A, and last is 2A. The order looks like EN | STOP | DIR

Should i rearrange the wires in the JST so that the wire that on the old card was connected to 1B, also is connected to 1B on the new card, and so on?
The EN | STOP | DIR part is in the same direction in the pinouts, even the whole connector is upside-down on the SKR MINI. Why is this? Is this just labeling the round pins?
Arrghh, I have so many noob questions…
