Hi,

I have been running an SIEG iKC4 lathe which was an ex-demo from Axminster but several months ago the ATC stop rotating and the machine hangs.

Several months of discussion with SIEG over email has concluded the KT510 CNC controller has an issue but they have advised that this is $1100 to replace (plus VAT, import duty and shipping.)

I cannot spend this type of money at the moment but really want to get the machine back up and running!

I was considering trying to source a used KT510 or replace the ATC controller with a new motion controller. (I can pause code and change offsets in the SIEG software still.)

The Yako stepper motor driver all works fine but I was not sure about the best route for a controller board, break out and motion controller software to just rotate the ATC. (I do not have access to an old parallel port PC so Mach 3 is not an option.)

Any advice on where I should start?
