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

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 ??

here are the electrical specifications

Working Voltage: 7~12VDC(Optimized 7.4V)
Rated Current: 450mA @ 7.4V : 1.7kgf.cm
Communication Link: Full Duplex Asynchronous Serial(TTL Level), Binary Packet, Multi Drop
Multi control through Servo ID: 0 ~ 253, 254(Broadcast only)
Maximum Baud Rate: 0.67Mbps
Feedback: Position, Speed, Temperature, Load, Voltage etc.
Various Control Algorithm: PID, Feedforward, Trapezoidal Velocity Profile, Velocity Override, Torque Saturator & Offset, Overload Protection, Neutral Calibration, Dead Zone

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

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

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 !

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 ?
I have posted below, config, home all, home z, and a snippet from the beginning of the code file
