Looking for freelancer to finish retrofit of K2 router was created by ArthurG
I hired someone last year to retrofit our K2 (KG5050) router after the K2 control board was fried. The primary goal (besides replacing the control electronics) was for it to be able to run LinuxCNC. After many false starts and wrong decisions made in the components to be used, and many, many hours spent wiring and re-wiring and testing things, it turned out that this project was too much for the young man I hired. He ultimately gave up after he failed to figure out the tuning of the servos/axes.
I have a computer programming background but I know very little about the world of electrical engineering and am hoping to find someone who can finish off the project - which according to the young man I hired, is just the tuning of the motors/axes, but which I suspect might require a bit more.
Ideally, I'd like to find someone local (we're based in Ventura, CA) but the control PC *is* setup with remote desktop access and a webcam on the table, so if you're confident you could do it remotely, with me on hand to E-stop/reset the machine as needed, I'd be okay with that option.

Well, to late, but no need for any of that fuss.
We need as much info as possible for the machine, motors, drives, controllers, whatever else, and a lot of pictures of the wiring and setup.
From you picture it seems like brushed servo motors, but i can not see if they have tachos, if they do that would make them analog servo, if not then most probably position controlled with probably step/dir signals or if older with up/down control or plain quadrature.
See, to much assumptions, so more pictures.
For analog servo, you can use this howto and with a bit of time and effort have the machine tuned pretty fast:
forum.linuxcnc.org/10-advanced-configura...ning-detailed-how-to
The link above will not work for any other type of control, only analog with Mesa boards, although it works with other controllers also.
