MK3.9 Upgrade Path to MK4S? Benefits?
Is there a direct upgrade kit available for a MK3.9 (upgraded recently with a 2 year old kit from MK3.5+ to MK3.9)? Looks like the path from Prusa is a MK3.9 to MK3.9S, then to MK4S. Seems like a long way 'round.
Is it worth the upgrade, or better to just spring for a MK4S or CORE1?
Thanks for the input...
