Random layer shift

Hi everyone,I’m currently trying to get my modded two trees sapphire pro to print at higher speeds. but I’m currently experiencing pretty bad layer shifting at random times. The printer will print 2 or 3 parts just fine and then suddenly a huge layer shift in the next part (see attached picture/ I have stopped the print once I have noticed the layer shift)I can’t figure out why it does it, so maybe some of you now some other tests that i can do to find the problem.For the Printer:two trees sapphire pro (core XY)stock stepper motorsRunning Klipper on a raspberry 4 - 2gb ram stepper drivers tmc 2208 - with 1.5 Amps motor current Speeds 110 mm/s printing - 150 mm/s travel acceleration at 4000 mm/s*sNow i know the pulleys are not slipping.And i have also tried the auto speed Makro for Klipper: https://github.com/Anonoei/klipper_auto_speedhere the results where max speeds of 250 mm/s and max accelerations of 10.000 mm/s*s so i guess the motors also should not be skipping steps at my speeds?So yea i don’t know what to do next maybe some of you know a few tests i can do to know what is causing the skipsThanks Alex
