From 77ceef962540f95967c73b5e8154d5da65ba49f6 Mon Sep 17 00:00:00 2001 From: David Ramiro Date: Sat, 17 Nov 2018 19:43:48 +0100 Subject: [PATCH] Tweak e-steps After getting my extruder to work reliably on a Vref of 1.100V on the TMC2208, I had to adjust my e-steps quite a bit from the original value from Anycubic. Assuming you have a TMC2208 on a similar voltage, this might work well right after flashing, calibrating your e-steps is recommended in any case. --- Marlin/Configuration.h | 2 +- README.md | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/Marlin/Configuration.h b/Marlin/Configuration.h index c8dad11..9b9c05d 100644 --- a/Marlin/Configuration.h +++ b/Marlin/Configuration.h @@ -612,7 +612,7 @@ * Override with M92 * X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]] */ -#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 92.6 } +#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 105.24 } /** * Default Max Feed Rate (mm/s) diff --git a/README.md b/README.md index 523c0f4..ed24cc7 100644 --- a/README.md +++ b/README.md @@ -29,8 +29,9 @@ While the i3 Mega is a great printer for it's price and produces fantastic resul #### Or download precompiled hex: - Choose the correct hex file: -- For TMC2208 with flipped connectors, use `Marlin-AI3M-XXXXXX-flipped.hex` - For TMC2208 with connectors in original orientation, use `Marlin-AI3M-XXXXXX.hex` +- For TMC2208 with flipped connectors, use `Marlin-AI3M-XXXXXX-flipped.hex` +- If you use the original stepper motor drivers (Pololu A4988 afaik), and didn't do anything to your connectors, you can try to use `Marlin-AI3M-XXXXXX-flipped.hex`.
