    He says Robo knows they have issues with their print texture. Robo claims it resisters for the steppers. How is that resolved? New board?

    I can't see any other solution given the proprietary board with all integrated, non-adjustable drivers.

    The all-integrated, non-adjustable bit is nice when it all works :)

    I dont want to be "that guy" but for whatever reason these you tube people have a large (or small) group of people that watch and listen to their every word. Regardless of if they know or dont know what they are doing, experience level etc. Due to this ALOT of OEM send them free stuff and keep them informed way more than we (the users) ever will be. Its unfortunate but its just the way it is :D I'd suggest calling Robo and asking for these things to be sent and continue to ask for a manager until you get an acceptable answer (if you dont get one out of the gate). I understand the frustration and dont mean to seem like I'm defending (I'm not) just explaining my point of view :D

    While I have always said when you pay for a new printer you deserve a working one out of the box, with the R2 you paid a bit of a premium and really deserve a working printer :)

    The R2 uses a 24vdc power supply so it is likely a 24vdc fan.

    Actually, the main board steps down the voltage for the fans to 12 volts. The 24 Volt power drives the hot-end heater and print bed heater.
    If the fan noise is a bit too much, @Lance Weston located a source for dual ball-bearing, 12 volt fans. Those fans should be quieter.
