SinCos encoder can be used with Argon already, the only missing thing is the analog interpolation of signals. So you will get only digital interpretation of encoder signals until the FW upgrade is ready.

but I’m looking forward to the FW Update argonto be able to use the linear scale COS / SIN

Linear encoder only usually leads to stability problems if there is any backlash or flexibility between the rotary motor and linear motion.

Dual loop system means that there is feedback device on motor that is used in conjunction with the linear encoder.

BTW, Argon hardware has been designed for dual loop, that only needs to be done in FW side too. I’m still thinking how to make it clean and transparent way.

I use rotary motor (DC) with lead screw and linear scale
there are no rotary encoder in my system (for now)

Do you use also linear motor in this system or rotary with lead screw?

when are you planning to release the firmware that will read linear scale Cos Sin?
I need for my project to the axis control by linear scale Heidenhain LS403
