+*  M129 - EtoP Closed (BariCUDA EtoP = electricity to air pressure transducer by jmil)
+*  M140 - Set bed target temp
+*  M190 - Sxxx Wait for bed current temp to reach target temp. Waits only when heating
+*         Rxxx Wait for bed current temp to reach target temp. Waits when heating and cooling
+*  M200 D<millimeters>- set filament diameter and set E axis units to cubic millimeters (use S0 to set back to millimeters).
+*  M201 - Set max acceleration in units/s^2 for print moves (M201 X1000 Y1000)
+*  M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
