From 13e25c306de7fcba2c462f7187ae07ba916880da Mon Sep 17 00:00:00 2001 From: Rumato Estorsky Date: Sun, 12 Jul 2026 16:47:01 +0300 Subject: [PATCH] Upgraded config for FlyingBear P905H. Attemp to make it pring faster with decent quality was successfull. Print speed could be up to 90mm/s with linear advance enabled. --- .../examples/FlyingBear/P905H/Configuration.h | 30 +++++++++---------- .../FlyingBear/P905H/Configuration_adv.h | 9 ++++-- config/examples/FlyingBear/P905H/README.md | 19 +++++------- 3 files changed, 29 insertions(+), 29 deletions(-) diff --git a/config/examples/FlyingBear/P905H/Configuration.h b/config/examples/FlyingBear/P905H/Configuration.h index 748cc196594..88f0998748e 100644 --- a/config/examples/FlyingBear/P905H/Configuration.h +++ b/config/examples/FlyingBear/P905H/Configuration.h @@ -70,7 +70,7 @@ // Choose the name from boards.h that matches your setup #ifndef MOTHERBOARD - #define MOTHERBOARD BOARD_MKS_GEN_13 + #define MOTHERBOARD BOARD_MKS_GEN_L #endif // @section serial @@ -1362,7 +1362,7 @@ * Override with M92 (when enabled below) * X, Y, Z [, I [, J [, K...]]], E0 [, E1[, E2...]] */ -#define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 800, 94 } +#define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 800, 96 } /** * Enable support for M92.
