Omlouvam se, blbes sem se podival na ten typ desky
Zajimalo me to, protoze sem o podobne desce uvazoval (teda kdybych nejak vyresil ty zabudovany drivery) tak sem mrknul.
Maj s tim vsichni evidentne problem. Primo i origo stranky uvadi toto (a s Marlinem to nebude fungovat jinak):
My external SD card ( in my panel ) is not working correctly
Ok so here's the thing : external SD cards are extremely bad. They just aren't designed to be talked to over wires, even short ones. You are supposed to talk to them over tracks on a PCB. Wires are antennas and pick up interference. This leads to corrupted data and errors. To talk over wires you need differential signals and/or error correction protocols, and SD cards can't do any of that. If we had a choice we would remove all panels with external sd cards from the planet, they are an infinite source of trouble for users. Works fine for some, they tell everyone how awesome it is to have one, then plenty of others can't ever get it to work reliably.
Because of this, while we did add the code to Smoothie for external SD cards, we can not *officially* support that feature. It's just way too much trouble and user problems flooding all around. If it doesn't work for you, we just can't do much about it, unfortunately.
Try to make the cable as short as possible, add ferrite, and try to trace the cable as far as possible from any source of interference ( like mains cables ).
Nicmene naslo se par postrehu, ze nekomu pomohlo vyresit to zapojenim slotu SD karty na volne piny desky (zrejme tim i castecne odpadnou problemy uvadene vyse.
I finally found a fix! I'm gonna have to cross test and see if it was one or both of the steps I did but I'll get back with that later today or tomorrow.
1)moved the pins (miso,sck,mosi) to the 5th stepper motor breakout pins instead of the suggest pins cause it wasnt working.
2)reformatted the sd card to fat32.
The main difference between the pin switches was that the lcd would freeze when I put in the sd card. So i figured it was at least trying to read the card finally and stalling. So I reformatted the sd card and it is now printing like a charm.
Urcite by aspon stalo za to zkusti, jestli sedi ty piny na detekci karty apod. pres M43
