Hi there. What great development have been taken place. I really want to build one v3 but just after deciding that and starting to source parts i ran into the following. I cant get my hands on those mechaduinos. There is a shortage of some component it seems that is used. If the shortage is not solved. Most v3 will be build without those mechaduinos...and what about the v4? Anyone knows maybe aby SanderI - Hangprinter
