Sorry for the necromancy, but I'm having the same issue. Did you ever get it sorted out?

EDIT: Try switching to PID control if you're on bang-bang at the moment.

First case, set bed to a few degrees higher than enviroament (25 -> 30) it went a bit higer, after it got <30 it went on again, got to >30, but after i pressed the button again, to disable the bed, which was off because it was on the rigght temp the button click caused it to go ON :\ another press of the button requested 30 degrees again, this caused to get it off, since it was already at 50
Note: i was also requesting the extruder to get hot, and the temp was reached.

at this stage the hot end is keeping its temp, the bed is waiting to get to the requested 30C, i click "disconnect", i get the message "some heaters are still on, shall i disable..." if i click YES the bed gets ON with no temp controll

reset arduino, close and re open repetier host
* arduino reset causes bed to go off

TEST: do not touch anyting else, request 60C (since the bed is at 55, to reduce wait time)
*bed reaches 56C LED goes off
*click button again so it can go cold - bed goes ON with no temp control

With this test i hope i have discarded electrical bug/noise, since as i stated before marlin controls the bed right. Im not sure why this is not working right for me only.

attached Marlin and Repetier configurations

The bed function works perfectly for me and many others. Apperently it also works for you, but something seems to change the pin as well. So you need to do more testing to find the real reason for the failure. I guess some function is set to use the same pin as the bed.

First you should start freshly resetted and turn bed on and off in manual control. Check if the lcd shows the correct temperature. The log with enabled ack should also show something like this:

09:22:22.155 : ok 11
09:22:22.155 : TargetBed:50
09:22:22.327 : ok 12
09:22:23.325 : wait
09:22:23.965 : ok 13
09:22:23.965 : TargetBed:0
09:22:24.963 : wait

When then works try other functions and see if bed turns on. Especially the command you send after turning bed off.

Also, since the bed cant be off, it will get hotter, BUT the next print will work and turn it off, until it reaches the new (lower) temp

Re: heated bed wont turn off on finish

luismanson — Sat, 05 Apr 2014 16:56:42 -0400

nope... just in case this is my end code:

G92 E0 ; reset extrusion distance
M107 ; disable fan
M104 S0 ; turn off temperature
M140 S0 ; apagamos CAMA
G1 Z10 F5000
G28 X0  ; home X axis
G1 Z20 F5000
M84     ; disable motors

Re: heated bed wont turn off on finish

repetier — Sat, 05 Apr 2014 06:04:49 -0400

You mean

M140 S0

does not turn it off?
That would be strange as it is also used to enable the bed.

Hi, im having this problem...heated bed works perfect on start and temperature control, but after the print ends it wont turn it off. i have to reset the arduino.
In Marlin works just fine, using the exact same settings, only chaing firmware
