Firmware Hex for artillery sidewinder X1 V4 for Hemera revo rapid change extruder

Hello All, I recently started 3D printing at 68 yrs old I have an artillery sidewinder X1 V4 I have been using Waggster mod 1.5 for BL touch.
I wanted to upgrade so I purchased a Hemera Revo Quick change extruder.I am mechanically minded and although it was advertised as a direct fit, (It was not) I managed to fit .
I am hopeless and tried to follow the E3D firmware mod without succses.
I found a Hex file compiled by Tom on thingiverse However after flashing found BL touch bed levelling will not function.
Can anyone help please with finding a source hex to flash for my Hemera setup to work Please?
All the best John
