SD/USB = reboot after heating | USB cable = success print

[ImmortalTeknik]

Hello guys,

I couldn't find anything relating to my problem so far on web so here I am asking your help.

Hardware:

• MKS Robin Nano V3 (Marlin from MKS flash drive msc)
• TFT 35 MKS (Color UI)
• MKS Wifi
• TMC2209
• 12V PSU
• Prusa I3
• The printer was working perfectly on a 8 Bit MKS Base 1.4 for 6 years.
• San Disk 2GB SD
• Kingston 16GB USB

The issue:

• With SD only enable in the config, the sd card is recognized, I launch a job, then marlin reboot as soon as the temps reached (190°C and 40°C). On 1 trial to 10, printer has time to home before it reboot when I relaunch the job very quicly before temps drop too much.
• With USB Flash Drive Support and Multi Volume, neither UBS stick or SD card is recognized. (SD init fail message when USB stick is plugged in).
• Printing from USB cable work perfectly.
• ESP3D can control printer but crash when trying to write on SD Card.

What I tried: -Remove MKS Wifi -exFat or Fat32 -Enable Disable OTG feature -Flash drive w/without msc. -SPI speed half

Attached are my Cfg files.

It's my first post here. I was so happy to swap my old 8 bit board for a modern hardware but I am now totally disapointed. 8 bit was limited but simple and less prone to bug I think, 32 bit seems to be far more complex and less reliable. Hope I am wrong, we will see. Configuration.txt Configuration_adv.txt

EDIT: I am now able to select a job from USB or SD but the printer still reboot as soon are temps are reached, sometimes just after homing.

Hello Viva,

Thanks for your reply.

I tried with both _usb_flash_drive and _usb_flash_drive_msc.

I would like to add something:

• After replacing my USB key, I am finally able to access it trough marlin and select a job, but the printer still reboot after all temps are reached. Printing is impossible.

So, after days and nights of head sracthing, I finally solved my issue: my gcode starting script was making marlin to crash. I just removed it and write a new one (default cura).
