can anyone help me figure out why my printer is hard sutting down when I go to run my preheat macro thats always worked? Hotend and bed heat find separately and togther outside the macro so I dont think its a power issue. I do see it looks like I need to replace a thermistor thats gone bad as Im getting negative temps but I dont see why that would cause a hard power off as soon as you try to run the macro. all the macro does is home, turn on all fans and preheat the bed and hotend so Im kinda lost
this is the macro

Printer Pre-Heat Macro

#####################################################################

[gcode_macro Preheat_Chamber]
gcode:
SET_HEATER_TEMPERATURE HEATER=extruder TARGET=150.0 # Set Hotend to 150C for Homing
SET_HEATER_TEMPERATURE HEATER=heater_bed TARGET=120.0 # Set Bed to 120C
Fans_Preheat # Set Fans to Preheat Mode
G28 #Home All
SET_HEATER_TEMPERATURE HEATER=extruder TARGET=265.0 # Set Hotend to 265C

#

thermistor issue has been resolved but printer is still powering off when using the macro I am so confused

#

hotend heats fine, bed heats fine with hotend on, all fans turn on and when I go to home all it dies
