Any help here.
S2 ATM has some partial retractions (sometimes), at first i thought it could be its Control Board so later i changed the Carriage Module but the reports of partial retraction still were there. I decided to change the Shutter though it was opening/closing successfully even if you runtest it on loop.
You can run some dispensing tests even for two hours without realizing any sign of retraction, but within two days you will get a report of partial retraction.
Later i decided to do a fresh software installation, problem is still there.
Any help on this.
