MKS PWC on MSK SGEN L V2 doesn't stay on #59

Open ILGROSSOFA opened 3 years ago

ILGROSSOFA commented 3 years ago

If I press the power button it turns on and after few seconds on display it appears "printers stopped" and it turns off. If I keep button pressed, it stay on until I release it, then it turns off immediately.

Hardware connections: PWR_DET connected to pin P1.28 PWR_OFF connected to pin P2.0 servo

My firmware modifications:

configuration.h

define PSU_CONTROL

//#define PSU_NAME "Power Supply"

if ENABLED(PSU_CONTROL)

define PSU_ACTIVE_STATE HIGH // Set 'LOW' for ATX, 'HIGH' for X-Box

//#define PSU_DEFAULT_OFF // Keep power off until enabled directly with M80

define PSU_POWERUP_DELAY 250 // (ms) Delay for the PSU to warm up to full power

define AUTO_POWER_CONTROL // Enable automatic control of the PS_ON pin

if ENABLED(AUTO_POWER_CONTROL)

#define AUTO_POWER_FANS         // Turn on PSU if fans need power
#define AUTO_POWER_E_FANS
#define AUTO_POWER_CONTROLLERFAN
#define AUTO_POWER_CHAMBER_FAN
//#define AUTO_POWER_E_TEMP        50 // (°C) Turn on PSU over this temperature
//#define AUTO_POWER_CHAMBER_TEMP  30 // (°C) Turn on PSU over this temperature
#define POWER_TIMEOUT 30

endif

endif

Marlin-bugfix\Marlin\src\pins\lpc1769\pins_MKS_SGEN_L_V2.h

if ENABLED(PSU_CONTROL)

ifndef PS_ON_PIN

define PS_ON_PIN P2_00 //PW_OFF, you can change it to other pin

endif

ifndef KILL_PIN

define KILL_PIN P1_28 //PW_DET, you can change it to other pin

endif

define KILL_PIN_INVERTING true //true : HIGH level trigger

endif

Please help me, thank you! GROSSO

I forgot to tell that I have TS35 display.

Can you provide your firmware sourcode to me?

ILGROSSOFA commented 3 years ago

I solved by myself!!!

This is the correct firmware modification (just add it) of file Marlin\src\pins\lpc1769\pins_MKS_SGEN_L_V2.h:

if ENABLED(PSU_CONTROL)

ifndef PS_ON_PIN

define PS_ON_PIN P2_00 //PW_OFF, you can change it to other pin

endif

The problem was caused by following instructions:

ifndef KILL_PIN

define KILL_PIN P1_28 //PW_DET, you can change it to other pin

endif

define KILL_PIN_INVERTING true //true : HIGH level trigger

Please rectify instructions at follwing pages for people using MKS SGEN L V2 with TS35 display: https://github.com/makerbase-mks/MKS-SGEN_L-V2/wiki/MKS_PWC

Now it works like a charm!

Thank you! GROSSO
