Absolute or Actual Positioning Strategy of a Robot

Hello I am not sure is LinuxCNC can use absolute encoder information. If it can, how? If not What have to be strategy for a safe robot diriving?

*Treditionally, we are using limit switches to prevent a crash. I do not want to trust only limit switches. And also I do not want to push each time home joint for each axis while I start robot.

absolut encoders can be used but are very expensiv on a 4mio scale
so most use simple 2000ppr on the driving motor to get the info
and the gearing + the stiffness of the robot makes the precision to move at 0,05mm

Hello bbsr_5a, I am using Delta brand ASDA-A2 model servos. I am not sure but in brochure it is written that absolute or incremental motor selection. If there is no like a parameter switching between incremental mode to absolute mode, probably incremental encoders have our servo motors. I am asking supplyer now.

It it very confusing and hard to implement homing axis each time isnt it? How can I implement secure robot starts ?
