please help with bed

I cannot get my heated bed to come on through the matter control interface. if i go to terminal and input M190 S50 it comes on great heats to 50 and then turns off. im at a loss any help would be awesome. here is my config h thermal settings:

/**

  • –NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table
  • Temperature sensors available:
  • -4 : thermocouple with AD8495
  • -3 : thermocouple with MAX31855 (only for sensor 0)
  • -2 : thermocouple with MAX6675 (only for sensor 0)
  • -1 : thermocouple with AD595
  • 0 : not used
  • 1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
  • 2 : 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
  • 3 : Mendel-parts thermistor (4.7k pullup)
  • 4 : 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!
  • 5 : 100K thermistor - ATC Semitec 104GT-2/104NT-4-R025H42G (Used in ParCan & J-Head) (4.7k pullup)
  • 501 : 100K Zonestar (Tronxy X3A) Thermistor
  • 6 : 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)
  • 7 : 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)
  • 71 : 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup)
  • 8 : 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup)
  • 9 : 100k GE Sensing AL03006-58.2K-97-G1 (4.7k pullup)
  • 10 : 100k RS thermistor 198-961 (4.7k pullup)
  • 11 : 100k beta 3950 1% thermistor (4.7k pullup)
  • 12 : 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed)
  • 13 : 100k Hisens 3950 1% up to 300°C for hotend "Simple ONE " & "Hotend “All In ONE”
  • 15 : 100k thermistor calibration for JGAurora A5 hotend
  • 20 : the PT100 circuit found in the Ultimainboard V2.x
  • 60 : 100k Maker’s Tool Works Kapton Bed Thermistor beta=3950
  • 66 : 4.7M High Temperature thermistor from Dyze Design
  • 70 : the 100K thermistor found in the bq Hephestos 2
  • 75 : 100k Generic Silicon Heat Pad with NTC 100K MGB18-104F39050L32 thermistor
  • 1k ohm pullup tables - This is atypical, and requires changing out the 4.7k pullup for 1k.
  • (but gives greater accuracy and more stable PID)
  • 51 : 100k thermistor - EPCOS (1k pullup)
  • 52 : 200k thermistor - ATC Semitec 204GT-2 (1k pullup)
  • 55 : 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (1k pullup)
  • 1047 : Pt1000 with 4k7 pullup
  • 1010 : Pt1000 with 1k pullup (non standard)
  • 147 : Pt100 with 4k7 pullup
  • 110 : Pt100 with 1k pullup (non standard)
  • Use these for Testing or Development purposes. NEVER for production machine.

thanks in advance. i ran into this problem before but can’t remember the resolution.
