I’m gathering my parts and beginning the assembly now. I have everything but the end mill bits and the conduit. Can anyone suggest a good assortment of bits for a beginner? Perhaps a good carbide kit? As for my conduit I plan a on starting with EMT conduit for the outer rails as I have printed 2 supports for my 30" span for the Y axis and 1 support for my 24" span X axis. Is upgrading the spindle rails to stainless a good move for rigidity if I am not using complete stainless? I am looking to have this as solid as I can.
