    • PT100 DAUGHTER BOARD, Reading 2000 c for Heat Bed

      Hi
      I recently purchased the PT100 Daughterboard latest version with jumpers.
      I have some issues.
      The reason why I bought this board, was to connect the Ultimaker 2 heatbed to the Duet wifi.
      That’s all, but when I connect it reads 2000 C for the Bed, I am using rep rap firmware2.x
      I followed the instructions on the web on how to configure firmware.
      The 2 wires for power go to heatbed connector on Duet wifi , and the other 2 wires I have connected to PT 100 motherboard (2 and 3 on the first connector )
      The jumpers are there on both connectors.
      I am only using 1 connector for the heatbed only, not for my hotend ( since that is a e3d v6 no pt100 sensor )

      Can you please tell me how to fix this issue ??
      How to properly configure ??

      Currently under the Heater section in config file I have this

      M305 P0 X200 ; set thermistor + ADC parameters for heater 0
      M143 H0 S65 ; set temperature limit for heater 0 to 80C
      M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
      M143 H1 S260 ; set temperature limit for heater 1 to 260C

    • RE: Need help to connect Herkulex smart servos to the Duet wifi

      hi
      Yes, I have all those documents already, and have used the servos connected with Arduino uno and Arduino due.
      I just want to know how can I use them with the Duet wifi ???
      a sketch would be appreciated for the connections,
      or since I know how to connect them to the Arduino board, is it possible to use the Arduino with the duet wifi ?? if so how ??

    • Need help to connect Herkulex smart servos to the Duet wifi

      Hi Guys,
      I have attached an image showing how the Herkulex smart servo is connected with an Arduino uno board ( RX is pin 11, and TX is pin 10 ), how can I connect the servo to the Duet wifi ??

      Hi
      I appreciate your help, thanks.
      In order for the servos run, they require 7.4 VDC
      I will have to use a drop down converter from 24V TO 7.4
      If you have an example of the wiring or a simple sketch , that would be very
      Much appreciated

    • How to connect Smart Servo to the Duet Wifi

      Hi
      I am currently building a Scara Robot and planning to use the Duet Wifi
      as my hardware controller for the stepper motors X,Y and Z.
      I am planning to use 2 smart servos Herkulex DRS -101 for my Robot Gripper since I already have them, and was wandering how can I implement these to work with the Duet Wifi board ???
      The servos can be daisy chained

      @dc42 Hi David, I am trying to get in contact with you concerning SCARA.
      I have posted a link on the forum , can you please have a look at it, I need your opinion.
      Thank you

    • SCARA Robot - want to know if DUET WIFI is the right choice

      Hello all ,
      I have built a Scara robot similar to JJRobots , with improved design modifications- for testing only. Once I have a board that can
      Make it work , I will port it to a more high end build SCARA.
      I have tried using marlin firmware to control it, but I never succeed
      I am using an Ultimaker 2 controller board to run the motors and end stops only .For now. It can home the arms when I use pronterface but after that it goes
      Crazy , I have tried several times, changing home offsets, scara offsets, but never work according to my setup. I give up. !
      I want to know if I should get the Duet wifi for my SCARA .
      I am already using the DUET wifi for my printer and I am very pleased.
      I came across the Scarlett SCARA , and I noticed he’s using the DUET and works fine. I have attached a TOP VIEW with some dimensions of the SCARA and a picture, any help would be much appreciated. Thanks !

    • Have to run G code file twice to begin print at correct height

      Hi guys
      I have this issue where I send the g code file to the duet wifi, and all is well until it starts to print. The nozzle tip is quite a few mm above the heatbed, I cancel, start another, then its perfect. Any clue why this is ?
