Urgent Mendel90 Question (2 replies)

Hi everyone. Im busy sourcing parts for a mendel 90 and wanted to know... It specifies the motor length to be 47.5mm but would a shorter stepper also nema 17 as requested work?

Also, in the BOM it just says "Microswitch" I assume these are the endstops? which ones would work?

Best.
