Re: [Emc-users] Heidenhain LS403 scale
Isn't the 403 a microAmp device? Or is it microVolt? Seems like most A/D would need an external preamp.

Does anyone have a working solution for using Heidenhain LS403 scales with
LinuxCNC? They're 2 phase sinusoidal feedback. Trying to connect to a mesa
7i95.

The common way would be to get a Heidenhain EXE box to do the interpolation

Look for a sin/cos to incremental converter or build one. They pop up from time to time on ebay for ~$100ea.
