Extruder 2 not working

I have upgraded my Hictop 3DP8 printer to dual extrusion, using the XCSOURCE dual J head nozzle extruder, so it now has 2 nozzles, 2 thermistors and 2 hot ends.

I can not get the 2nd hot end to heat up. All components are working but I can't get power to the second hot end.

When I heat nozzle 1 using the LCD I see the target temperature set and watch the thermistor temp rise and stabilise.

When I heat nozzle 2 using the LCD I see the target temperature set and the thermistor stays at room temperature for around 15 seconds then I get a print fail error.

I understand that this mobo will only run one extruder at a time so I have avoided running both heaters at once.

I suspect it is because I need to assign a pin number to HEATER_1_PIN in pins.h

I have tried 7 and 8 with no success.

The motherboard is an MKS base V1.3 and I have defined MOTHERBOARD BOARD_RAMPS_14_EEB in config.h

Can ayone tell me what I am doing wrong?

Thanks in advance

Motherboard BOARD_RAMPS_14_EEB knows nothing about D7

EEB sets D8 heated bed, D9 hotend 1 and D10 hotend 0

use Motherboard BOARD_MKS_13

then it knows about D7 and becomes // Power outputs EFBF or EFBE

So D7 then should become hotend 1
