      I want to upgrade my Tevo little monster delta printer, which would be the better choice, a Duet Ethernet or a Duet Maestro?

        What is the specification of the stepper motors in the TLM, and what is the power supply voltage?

            I guess that both would do nicely, I am using the both the Duet Ethernet and WiFi on my TLM's
            because I prefer the maturity of them compared to the Maestro.

              do the Maestro and wifi/ethernet boards use the same firmware?

                  Do the stepper motors have part number labels on them? If not, can you measure and tell us the resistance of one stepper motor phase, and the length of the motor?

                    1.9 ohm's per phase, 48mm in length, 1.8deg, part no is 17HD8401-C5.18

                      My guess it that it has the same winding as 17HS8401, which is 1.8A rated current, 1.8 ohms phase resistance, 3.2mH inductance. The rated current is a little higher than we recommend for the Maestro, but if you fan-cool the Maestro then you could run them at 1.2A or 1.3A current, which is 66% or 72% of rated current, so in the right ball park.

                      The Duet Ethernet could run those motors without fan cooling.

                        I have been running mine at 1.1 amp's for months now with no issues and they run quite cool
