Motion Control with BeagleBone Black or Raspberry Pi and ClearPath-SC Servos

Watch this video to learn about using ClearPath SC (Software Control) with single board computers such as BeagleBone Black or Raspberry Pi.

ClearPath-SC blends a sophisticated, networked motion controller into the already compact ClearPath all-in-one servo motor system. Using ClearPath SC, your single board computer, and C++ libraries provided by Teknic, you can coordinate up to 48 axes or more. This system also gives you access to features such as g-Stop tuning, head-tail moves, conditional torque limiting, position capture, and more.

Teknic wants your feedback. Like this video? Give it a thumbs up! Be sure to comment with any questions about motion control and let us know what you did or did not like about the video.

For more information on Teknic ClearPath servos, subscribe to our channel and visit Teknic's website.

ClearPath SC is controlled via a host application in software. SC gives customers greater flexibility to meet the needs of conditional and complex applications. The SC does not use a third party indexer like the SD series nor input triggers like on the MC series. Everything is written and moves are commanded using your C++ application codes and Teknic's API.

We're using a pair of SC-HP motors to drive the azimuth and elevation axes of our 12.8m satellite dish restoration project. The sFoundation library has been super-helpful in the process, and has significantly shortened development time on this project.

amazing, super interested in these motors now! Going to add them to my next CNC build!

[adriansinclair]

very impressive. I'm excited again about my hobby project I'm about to restart using Teknic gear. I'll be reaching out to you soon.

I would love to see a more in depth video on this subject.

Hello,
...


I am going to try these types of servos one day. They are nice!

Sooo awesome! It would be great in you could develop a series of Nema 17 Motors for 3D-Printers! :D You would sell them like crazy!

[Electheo]

Do you have products to drive a permanent magnet synchronous servomotors? It’s for a 400VAC motor meant to drive light electrical vehicles.

Your product environment looks really friendly to use, I hope to hear from you.

[americocarvalho]

Congratulations for your products. I am exploring options for autonomous and teleops robots (hobby - not professional yet) and see a great fit in your products, except: 1) I don't see reference to support of Can Bus 2) An AC power supply sounds to be the norm to use, requiring then a power conversion for DC Power (batteries) - any architecture suggested for this? 3) I am leaning towards Nvidia Jetson controllers. Would you release docs/videos for the integration with the Jetson series? Thank you in advance,

Im thinking to make a retrofit for a Biesse 321r nachining center with clearpath ( 3kw on X axis). The question is: Is available any software who can comunicate limux pc with Linux CNC installed with the beaglebone and make controlable the servos straightforward from linux cnc? Controlling clearpath sc4 IOs from linux cnc would be needed too.

Hi! Thanks for the video
Could you share the part number of the shaft couplers please? also, I'm looking to couple a teknic shaft of 12.7mm to a rod of 30mm...

Hi, thank you for another SC-series video!

I am trying to wire ClearPath-SCs in "Step and Direction" mode to Masso CNC controller.
The controller has Differential Signal (-5v to +5v) Step & Dir outputs, that I believe, can be directly connected to motor's A and B inputs.
However, it seems, that SC4-Hub has different A and B inputs schematic and is not a direct pass-through from SC4-Hub to the motor.
Quote from the user manual: "ClearPath-SC motors can accept inputs from devices with logic high ranging from 5-24VDC, but the SC Hub, by default, accepts 24VDC NPN type sensors or simple mechanical switches."

Is there a recommended way to modify the SC4-Hub to directly pass through A & B inputs to motors? Desoldering a component or two from SC-Hub is not a problem for me. Jumpers J0A..J3A and J0B..J3B seem to be likely candidates :)

Or is there another way to connect the servos to the controller in this case?
Maybe, extracting 4 middle wires from the 8-Pin Molex connector on SC4-Hub side, and connecting them directly to CNC controller will do the trick?

Other than the sFoundation code, do you have anything to help develop a single SC NEMA-34 motor system, something that could run on a fast Teensy 4.1 or similar MCU (non-Linux) system? Any documentation for how to control the motor without trying to dig through 20, 000 lines of industrial level control software?

[cfishfood]

What is the linear rail system you used in this video- it looks awesome with the mount points for the limit switches!

[SuperYellowsubmarin]

Is there a way to control only 2 motors without the hub ? Is the hub for wiring simplification or is it required between the controller and motor ?

[Dev_Everything]

I am a c++ developer and hobby fabricator. Can the servos be flashed for C++ commands and then later on run gcode? or are they two separate servos?

[perrys]

Is it possible to connect big electric engines to this system? Like a conveyorbelt engine?

[dianemuresan]

To control a 3 axis glue dispensing machine, would it be better to use a setup like this with Clearpath-SCs and a raspberry pi or Clearpath-SDs and a PLC?

[isaacvargasnina]

hello. please do you have examples using your SC, for robotics applications. for example robot arm, delta robot. thanks a lot.

[cheblack]

Thanks. I need to control direction, speed and position and there is no mode including those three. So if I chose to control direction and position with wires, I need to set acceleration, deceleration and speed before the movement using some commands. I don't want to use their software, but build a stand alone communication with the motor. Can you suggest me where to find the commands they are using to communicate and set the motors.

[FC-xryp]

how about the C# windows example too ?
