I am using a derivat of Roxys improved ABL firmware and the sd card in a Smart Discount LCD doesn't print. The card is seen, I can select files, but it wont print. I uploaded a FW from another machine with the same LCD and it printed from the SD card just fine, so it is FW issue. I am currently comparing the two, but I don't really know where to look so I was hopeing someone could help. The Eight3C fw is the one that doesn't print from the SD card.
Thanks

In Marlin_main.cpp there are all kinds of differences in the SD Memory Card commands. They are like this:
*(starpos) = '\0'; turned into *(starpos-1) = '\0';
There are 4 or 5 places and those have to do with the name it is looking for in the directory. Specifically, case 23: , case 28: , case 30: , case 32: , case 928:
And then in SD2Card.cpp and SD2Card.h the Eight3C version looks much more mature. There is a lot more code. But all of the other SD files are identical.
Which version works? My guess is the Eight3C version works and the other one does not? If the file name is not being properly terminated with the *(starpos)='\0'; line, I can believe you can select but not open the file. I would change those first. But then if that worked, I would also try swapping in the more mature sd2card.cpp and sd2card.h file. That code looks more mature.
Hey thanks for the quick reply. It's the other firmware that works, not the Eight3C. Eight3C is what I want to use. I saw these differences too, but didn't know what they were. I will try the change and let you know.
I changed the *(starpos) = '\0'; to *(starpos-1) = '\0'; but no change.
Unfortunately... This is the kind of problem that is very difficult to debug remotely.Quote:

It is the reprap discount LCD's SD card that cannot run/print from card.
You could tell the Viki LCD people to send me a card. I'll get it working! :) But not having hardware makes it very difficult to debug.Quote:

I copied the marlin main into the eight3c and got a bunch of ultralcd.cpp errors that are below. Not sure if this helps though.

Roxy,
Don't waste your time on this any longer, I downloaded the latest Marlin and implemented the eeprom save G29, it's working great.
Thanks anyway.
