On pinout image - Z stepper DIR pin wrong

[clowrey]

The Z stepper DIR pin is PB7 not PC7

Can be verified - the Marlin PINS file has the correct PB7 pin defiined.

Just had this same issue tonight. After going to the schematic from the pinout diagram, I found the issue was the same as this currently has. Can you PLEASE update this?!?

There are really 6 items that are "wrong or missing or added that should not be" to the original BTT PIN Diagram.
#1 Z DIR PIN is PC7 BUT Marlin 2.0.5.x's pins_BTT_GTR_V1_0.h file shows it to PB7. #2 EXTENSION-1 Header PIN number 2 is PH10 BUT the BTT's schematic shows it to be PI10. #3 Raspberry pi Header Column 1 and Column 2 both have a count of 21 PINS, BUT BTT's schematic only shows 20 PINS in each Column. There is one extra "NC" PIN in each column. See my attached file for which two PINS "were added that should NOT be there". #4 The Stallguard BLOCK is MISSING the PIN number or name for the PIN that each DIAG1 PIN is connected up with. BUT, the BTT's schematic indicates that the DIAG1 PIN from each Motor Drive is connected to its corresponding Limit Switch/Endstop. So X-DIAG1 should have X- (PF2) added; Y-DIAG1 should have Y- (PC13) added; Z-DIAG1 should have Z- (PE0) added; E0-DIAG1 should have E0 (PG14) added; E1-DIAG1 should have E1 (PG9) added; and E2-DIAG1 should have E2 (PD3) added. #5 The HOT BED or BED OUT is MISSING a PIN while the Marlin 2.0.5.x's pins_BTT_GTR_V1_0.h file shows it should be PA2, which is missing so it needs to be added to the PIN diagram. #6 There is MISSING names for the last Limit Switch in the X- Row and E0 Row. The last Limit Switch in X- Row I added the name "Extend-Interface-2". The last Limit Switch in E0 Row, I added the name "Extend-Interface-1". I chose those names because BTT's own Wiring-Diagram names them as "Extend Interface". We need those un-named connectors named so that when people ask questions on how to hook up additional equipment, we can answer in writing. Adding a NAME to those connectors makes our job easier when discussing issues.

I have created a PIN file showing these correction and a Color_PIN file also showing these corrections. They both can be found at my github page: https://github.com/GadgetAngel/GTR-V1.0-Stepper-Driver-Jumper-Configuration-Manual

Hi @GadgetAngel

I have created a PIN file showing these correction and a Color_PIN file also showing these corrections. They both can be found at my github page: https://github.com/GadgetAngel/GTR-V1.0-Stepper-Driver-Jumper-Configuration-Manual

after unpacking the archive, the files have only 1kB and are damaged

4 years later still not fixed... what a shame... Thank you @GadgetAngel for fixed version.
