Morning everyone, I now find myself in a similar position to Francoadi in 2022 when he had no set up material for the Weihong Lambda 21a CNC controller. I recently purchased a machine from China and in trying to set it up have encountered a spindle fault: "Tool clamp output has signal or tool clamping signal is not detected."

I am trying to get help from the supplier but unable to get any meaningful assistance with regard to wiring diagrams and set-up manuals for the Lambda 21a controller. Can anyone help? Does anyone have any documentation for the Lambda 21a?

I would appreciate any assistance the community can provide. Just in case, my WhatsApp number is (268)764-7403. (Antigua & Barbuda)

Many thanks.
