From c429a4b3ec9b80e7927b6e75e8b6f1241cf369d0 Mon Sep 17 00:00:00 2001 From: Bo Herrmannsen Date: Wed, 3 Dec 2014 14:37:16 +0100 Subject: [PATCH] Toshiba Stepper Driver support Tosh stepper drivers need to be driven slower, so the stepper code was interleaved to separate the pin HIGH from the pin LOW. This adds enough instructions to make it work, without needing nops. --- Marlin/Configuration_adv.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/Marlin/Configuration_adv.h b/Marlin/Configuration_adv.h index 6398f4161..bce45851d 100644 --- a/Marlin/Configuration_adv.h +++ b/Marlin/Configuration_adv.h @@ -219,9 +219,11 @@ //#define QUICK_HOME //if this is defined, if both x and y are to be homed, a diagonal move will be performed initially. #define AXIS_RELATIVE_MODES {false, false, false, false} - +#ifdef CONFIG_STEPPERS_TOSHIBA +#define MAX_STEP_FREQUENCY 10000 // Max step frequency for Toshiba Stepper Controllers +#else #define MAX_STEP_FREQUENCY 40000 // Max step frequency for Ultimaker (5000 pps / half step) - +#endif //By default pololu step drivers require an active high signal.
