Custom delta firmware sources Help!!

This is my first printer to build from scratch, and my first delta printer , i have a problem using marlin to make a custom firmware for my delta printer , and it has been a while since i ever dealt with simple programming, there are very few helping forums that are interested in delta printers, and too bad i have no specific model to memic, so i made it custom from scratch
I am asking for if
1- there is any educational videos that goes step by step to make a custom firmware for a delta printer , i mean really for dummies level , i feel like a child working through this high level programming and delta caliberations
2- if there are any professional services for firmware making , i have seen fiverr, but find no professional service worth , any recommendations

will appreciate your help and answers guys thanks

Why does your delta need custom firmware?

Hi dc42
Cause I really do not need where to start , I began with a biqu kossel dimensions , but changed the board to skr 1.3 , switched drivers to tmc 2130 , and bought the motors, fish eye and arm lengths that were available ,
so by time i realised that i have made a different version of the product, and have no clew how to edit firmware , and even biqu has discontinued their support for their product long ago for problems it showed , so i have no updated firmware , nor the knowledge to make one , specially for a delta , i feel lost , that is why

Do you have an alternate method?, please tell , as i feel like being lost , and don't know where to head in the marlin function , and what parts should i edit , and which i don't have , will really use a help if there is some kind of general detailed guide for non professionals , or a video , or even a course , or a custom service provider

Dear DC42 . H parameter in M665 is the level of Z-probe , not Z coordinate in DElta printer. In Delta X,Y,Z -in home must be 0.X,Y,Z coordinate are equal in DELTA. Maybe the firmware must be change?
DC42. In config.g I set in M666 X=0 Y=0 Z=0. Why Z = 999?

M666 sets the corrections to the endstop switch positions, not the actual locations.

Please post your complete config.g and homedelta.g files. You will get faster responses to questions relating to RepRapFirmware if you post them at [forum.duet3d.com].
