New CO2 stage #35

Open jirhiker opened 2 years ago

jirhiker commented 2 years ago

added new co2 stage with encoders. replaced X and Y. Z and the motion controller keep the same

needed to make new cables for X and Y. required limit signals to be inverted. added hex inverters to both cables.

updated stage1.ini and stage2.ini config files. added EncoderType changed DisplacementFullStep=0.0127 10TPI, 200 step == 0.0127 mm/step set EncoderResolution=0.001 == 1 micron in mm

KP=0.185 KI=0.15

these seem like good parameters. -0.003 immediately then takes a few seconds to completely eliminate the error
