@jay_s_uk Thanks for your reply. So, can you tell me which Boards need to be installed or which Duet3D products are needed to assemble the CNC robot?

Hello! I have a project to create a CNC Milling machine from KUKA KR210 Robot using KRC2ed05 controller. I have configured the E1 external spindle and installed a 7.5 KW Spindle on the KUKA Robot, and connected it to a Delta C2000 Inverter model VFD110C43A. Now what other conditions do I need to connect it to the KRC2 controller so that the robot can control the Spindle. Can anyone guide me? Thank you very much.
