Heated Bed Loses Setpoint during first layer

For some reason my heated bed gets to layer 1 set point then at the start of the print sets the set point to 0 as shown below. I manually override the 0 setpoint back to the correct value however, I'm not sure why this happens.

Here's my starting script:

Code: Select all

G28  ; home
G1 Z0.2 ; move z up a layer height
G1 X10 Y5 F500 ; Go to the front left corner

M190 S[bed#_temperature] T1; set bed temp & wait. 
M109 S[extruder0_temperature] T0; set extruder temp and wait 104 sets temp and continues

G92 E0 ; zero the extruded length
G1 X150 E15 F200 ; make a thick line to prime extruder
Thanks in advance

Why do you have " [bed#_temperature]" in your starting script?

Shouldn't it not be either "[bed0_temperature]" or " [bed1_temperature]" ?

I've never noticed that. Should it be bed0 or bed1? Bed temperature is setup to use T1 and the exturder T0.

T0 or T1 has no influence to the heatbed, why ever S3D shows it like an extruder. You must only check on the alternative box in the line Controller Type. The line temperature Identifier (T0 - T5) is only available to extruders.
Be sure, that the temperature for at the moment not used extruders is set to zero AND the box Wait ... is unchecked!

The GCode examble is generated with this settings as shown.
