Scara Arm new to duet3d, i have some doubts please help
-
So i have built a scar arm (1m long), the hardware part is done, and I am using stepper motors for StepperOnline. My doubts are
1- How easy is it to implement Duet3D to scare ( I have worked with Marline before)
2 - Which board is better for my application, Duet3 or 2?
3 - I am building a construction robot, so I do not need a build plate. Can I use Duet3D without a build plate
4 - Can I use my stepper drivers, which I bought from StepperOnline, because I have encoders too
5- do i need a screen? can i use a monitor for it? while using a web server tooi am going through Duet3D docs too, if someone has any suggestions or resources, please send me
Thankyou

Have you seen these pages?
https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_SCARA
https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_five_bar_parallel_scara -
A Duet 3 would be the best choice at this point.

You do not need a build plate.
-
You don't say which steppers/drivers/encoders you have, but they will likely be able to work with the Duet. https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external

At the very least, you would need a computer with a web browser to interact with the Duet Web Control software to control and configure the Duet.

i am going through those docs
Sorry, i forgot to ask, do these have auto levelling for scara, because I will be printing on the floor, which might not be levelled properly, so I would like to know -
@kumar22222 yes you can use mesh compensation with SCARA kinematics if you have a Z probe. Also, if you build your SCARA platform to stand on three adjustable feet, there is a facility to probe the bed (i.e. floor in your case) and then tell you how much to adjust each screw to get it level as possible, so that mesh compensation has less work to do. I have a SCARA printer that uses both of these facilities. See https://miscsolutions.wordpress.com/2017/09/24/improving-the-robotdigg-scara-printer/.
