romucifer commented 3 years ago

Mauvaise combinaison de la carte SKR et de l'écran TFT Regardez # 1312 my mod marlin work i have make cable exp3 (skr e3 dip v1.1)to exp1 and exp2 (tft24 v1.1) but only sd card tft not work in marlin mod

radek8 commented 3 years ago

The EXP3 connector does not connect to an external SD card. In Marlin mode you can only use the SD card on skr e3 dip v1.1

However, the condition is a correctly configured Marlin you have to allow

define SDCARD_CONNECTION ONBOARD

romucifer commented 3 years ago

Le connecteur EXP3 ne se connecte pas à une carte SD externe. En mode Marlin, vous ne pouvez utiliser la carte SD que sur skr e3 dip v1.1

Cependant, la condition est un Marlin correctement configuré, vous devez autoriser

define SDCARD_CONNECTION ONBOARD

for sd on board skr e3 work perfect in marlin mode it is posible mod pin for active sd card tft in marlin mod

radek8 commented 3 years ago

Marlin can do a lot, but your board has an EXP3 connector and it doesn't have the pins needed to connect an SD card in the TFT. The SD card in TFT communicates via pins which are connected in the EXP2 connector. It is understandable?

romucifer commented 3 years ago

I understood that the skr e3 dip v1.1 only has exp3 but I wonder if by remapping the pins not to use as for example the swd pins to the entries of the sd support on the skr e3 dip v1.1 card

This repository is about software and radek answered your questions already. Please be so kind and start a ticket in the corresponding hardware related repositories for additional information and close this ticket here.

Thank you

Everything is possible if you know what you are doing :-) It will be more suitable for you to buy new HW that will better suit your needs.

oldman4U commented 3 years ago

The SKR E3 DIP is a direct replacement for the Ender 3 which comes with an onboard SD card and a 12864 display which has no SD Card. So you need another mainboard or you use the TFT based storage options with the touch mode. Those two options you have without the possibility to brake your hardware.

You will have to find where the pins are routed under the motor drivers, but you will miss 2 more pins

radek8 commented 3 years ago

Isn't this better?
