Motor skips after heaters are switched on or off. This is my current tool definition gcode:
; Tools
M563 P0 S"Extruder" D0 H1:2 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C
Is it possible there are other ending scripts related to extruding when the tool is selected/changed?
Thanks!
@droftarts ok so I managed to successfully update the firmware, thanks a lot. However no luck with the heater problem. I am using the wiring as described below. The bed heater still heats up immediately as soon as I switch on the board 
any other suggestions of what I can do?

Hi,
I am trying to connect the bed heater using an SSR. The connections so far are as attached below. My problem is that whenever I switch on the power supply, the RED LED of OUT_0 switches on and remains on. Also, the bed heater starts to heat up immediately. Is there someone who can help me with this problem please?
I also tried to set a temperature for the bed heater from the interface but the temperature continued increasing beyond this set temperature.
Thanks.
@droftarts thanks a lot for your reply.
The SD card was inserted in the board when I uploaded the fzip fila and still is. I have tried to run M21 but DWC seems to keep on buffering and the g-code is not sent. "Drive is unmounted" message is still displayed.
What do you mean by reset the board please? Do I need to restart it by switching it off and on again? Or do I need to actually press the reset button on the board?
@droftarts I tried to update the firmware as instructed. I managed to upload the zip file to DWC. I read that I am supposed to be asked to install the firmware. However this did not happen.

@Phaedrux
With the SSR disconnected as shown in the picture, the LED light still switches on and voltage is 24V across OUT_0.
When removing the bridging (green wires) the LED switches off and the voltage is 0 across OUT_0 terminals.
(The SD card is still inside the board)
@jay_s_uk with the sd card removed I still got the same result as above^

What do you mean by removing the SD card and resetting please? Will I lose all data by doing so? Sorry for asking but I am new to 3D printers.
