Description

Unable to print from usb drive. I have fresh MKS Marlin v2.0.x with usb enabled and ups and pwc module + filament sensor on robin nano v3 ts35. while choosing file from usb drive, printer is heating, leveling and then it stops. I can hit resume but it is not resuming. Before it stops bed is going down and up for ~10mm. when I will send the same file trough usb cable and simplify it is printing without and issue. Was trying to uncomment power loss but it did no change the behavior.

Update. After changing TFT_LVGL_UI to Marlin Color UI everything is working fine. I can print via usb w/o any issues.

Hello I have the same problem, but I would like to use the original interface and not marlin ui. If I connect the signal from the ups to Mt det 2, my printing pauses to replace the filament. How can we connect the signal of the UPS?

Use Marlin ui. It’s much better. With many more options

Hello

Sorry for my english I don't like marlin UI and I use MKUI's wifi. Using the BL touch and the PWC, I plugged in the PWC like this:

define SUICIDE_PIN PW_OFF

define KILL_PIN PC4 in robin nano_V3.h .

The UPS #define POWER_LOSS_PIN PW_DET but at power failure the Z does nothing
