Blender 2.9

shortcuts

SHIFT z: switch wireframe and object mode

f: fill faces or edges between edges or vertex

a: select all

ALT+a: select nothing

c: circle select

b: box select

SHIFT+b: zoom to box

SHIFT+s: cursor move or selection move

w: cycle between selecion modes

numpad emulation

edit → preferences → input → emulate numpa

enable 1,2,3 switch faces,edges,vertex: edit → preferences → keymap → search mode

select mode toggle: ALT+1

select mode toggle: ALT+2

select mode toggle: ALT+3

fix boolean operations

Sometimes boolean difference fails. Before try on each object:

edit mode

select all vertices A

vertex (top menu) → Merge Vertices → by distance (this operation remove duplicate vertices)

hide / show

select (multiple) object and SHIFT+H to hide others

recall others with ALT+H

edit mode

TAB key

activate Vertex select with 1, Edge select with 2 and Face select with 3

Create new object from selected vertex:

duplicate with SHIFT+d

ESC to exit from grab mode

parent selected with “p”

exit from edit mode with TAB and you will have two objects

CTRL+l: select touching vertex, edges, faces

Recalculate normals (to solve bevel problems): select all with “a” and hit “shift+n”

knife mode K:

c for angle constrain

z for cut all deeper edges

put vertex same X, Y or Z:

position the 3d cursor at the Y location

set the pivot point to the 3d cursor (. period key)

then scale by zero on the Y axis (S Y 0)

Hey! Apologies for Necro'ing this thread but I think I have the exact same board and machine as you, and was running into the exact same problem. I don't know if you wound up solving your problem, but the change that worked for me was two fold:

twist the spindle wires together between the motor and the board, adding a shield if necessary (I eventually removed the shielding when I accidentally damaged it)

solder a 0.1uF ceramic capacitor (make sure it is bidirectional!!!) between each terminal of the spindle motor to the spindle motor body itself. Ideally, you would also solder a third capacitor between each motor terminal, but I did not do so and have not yet had the random dropouts I did before.
