Well, issue. This one doesn't seem to fit any of the 'standard' problems, and I'm scratching my head.
Extrude forward, all is good with the world.
Retract? LCD goes bonkers. Motor skips steps. LCD stays bonkers -- until I extrude again.
This is insanely repeatable.
I tried slowing down the UI_DELAYPERCHARACTER from 320 to 500 in ui.h, in hopes of it just being noise. I'm using the short cables with the LCD, unshielded.
Anyone?
I did notice that the pins for extruder drive are:
#define E0_STEP_PIN 26
#define E0_DIR_PIN 28
#define E0_ENABLE_PIN 24
and the data pins for the display are:
#define UI_DISPLAY_D0_PIN 23
#define UI_DISPLAY_D1_PIN 25
#define UI_DISPLAY_D2_PIN 27
#define UI_DISPLAY_D3_PIN 29
Physically close -- I'm wondering if I have a crappier than usual RAMPS knockoff.
