Got a Maestro, please help me with setup.



  • I have a Robo R1+ that is getting a complete overhaul.

    What I have going:
    Titan Extruder, V6 w/volcano
    BLTouch
    24v Prusa MK52 clone
    Maestro controller
    RepRap discount controller. Don't really need anything with the web interface, but I like a control station at the machine.

    Here is what I need to do, please tell me what I can't do, and/or point me in the right direction:
    Setup of the steppers looks standard, no problems there.
    How to best use the E3D thermister for the volcano
    Possible active heated chamber? I print a lot of ABS.
    Sensorless homing seems straight forward. My new X carriage and idler accommodate sensorless homing.

    If I go with an active heated chamber, can the maestro handle chamber temps or do I need to keep it outside the chamber?
    Does the maestro need active cooling at all? Currently, the RAMPS it runs has a fan.

    I think all that should get me started 😄



  • Oh, power supply.

    I have the OEM bed reconfigured to run off a 24v Meanwell power supply (controlled via SSR). I would like to have the Maestro kill power after a print is done and the extruder is cooled down.

    A: Can this be done where I still have power/ethernet to the Maestro
    B: Do I need a CPU type power supply for this?

    You've got the option of using a PanelDue, or the Maestro supports a compatible 12864 LCD with rotary encoder.

    Use the values from the E3D documentation.

    Possible active heated chamber? I print a lot of ABS.

    Anything is possible. The maestro has 2 extruder heaters. You could use the second one to control an SSR to power a chamber heater.

    Sensorless homing seems straight forward. My new X carriage and idler accommodate sensorless homing.

    Sensorless homing can work well. It will require some tuning though.

    If I go with an active heated chamber, can the maestro handle chamber temps or do I need to keep it outside the chamber?

    It would be best to keep it out of the chamber.

    Does the maestro need active cooling at all? Currently, the RAMPS it runs has a fan.

    If the maestro is going to be enclosed, then yes active cooling is recommended. Ideally it should be mounted vertically to allow for more efficient convection from both sides of the board.

    I think all that should get me started 😄

    There is an exemple guide for upgrading an Ender 3 with the Maestro. While specific to the Ender 3 it should give you an idea of what's involved converting and commissioning a printer with the Duet.

    Typically this would be done with an ATX power supply and using M80/M81 to turn it on and off. There's also the option of using a separate 5v power supply and SSR to control the main PSU.

    I've never bothered to go down that route and don't really have any guidance to give on that one.

    The TMC2224 drivers on the Maestro do not support senseless homing.

    Does the maestro need active cooling at all?

    Above 1A motor current we recommend fan cooling. Likewise if the bed heater draws 15A or more.



  • Looking at the option of a secondary 5v power supply for the Maestro and then controlling the main 24v power supply via SSR, where would the 5v input to the Maestro be? And then how many amps are required for the Maestro?

    And then 10-4 on needing homing sensors. Not a big deal to put them in.



  • it depends on what you run on the 5v line.
    if its just the cpu, then normal usb power output is enough.
    if you run your fans on 5v, then scale accordingly.



  • Can the Maestro be configured to turn off the hotend heatsink fan? That is really the only reason i would have to kill power after a print.



  • @Rat_Patrol
    the standard configuration in the configurator is that the hotend fan turns off once the hotend reaches temperatures below 45C.



  • @Veti
    Sweet.

    I'll be working on the conversion over the next week or so, will post back if I have any questions!

    Thanks all!
