Hey all. First post here but log time site user. I recently bought a Boss 4 r-ram. I want to retrofit it because I want to improve accuracy i.e. cnc heads and custom bike work, and I like the new gcode better than the old boss code. I want to spend as little money as possible. I was trying to decide if it would be cheaper to build my own retrofit or just buy a kit and get the control features I want. I want a system that would use encodes and the stock limit switches on the boss. I would like spindle speed control using the stock spindle controller alone with the auto brake and auto spindle on/off. I’ve heard of people doing this with the Larkin system, any info on this. Also with the Larkin system a lot of people seem to use stock stepper motors would this be possible with my system. I just want some input form some smarter people so thanks for the help
