@verminsup First, are you SURE those are BLDC motors?

I see a ribbon cable coming out of the encoder, and a two-wire connector coming out of the back of the motor, so I think they are DC motors with an incremental encoder.

Let's start there and see what you need for a motor-position controller after determining what kind of motor you have.

If you can post:

What Stratasys machine you are trying to convert Links to any documents for that printer Close-up photographs of the motor connections Names, numbers or other markings on the motors you are trying to control

It would help a LOT.

I fixed the issue. I connected an thermistor and it worked completely fine. First I thought my CAN Connection didnt have enough bandtwith because everything else worked fine except the motor.

The issue was that the 1XD Exp Board was running firmware 3.2 and the Mainboard was running firmware 3.3.

Thanks for joining the family!

Ok sorry, i was unaware of the crypto chip change in the SE.

the DC motor closed loop control software is what i had in mind, i just wanted to show you the finished project to show that someone used it on a similar project.
I have some experience with the YAPSC:10V, the standalone version to convert step/dir interface to the +-10V logic that industrial AC servo drives use. But i couldn´t get it to work. So i have 3 boards sitting here collecting dust.
The original creator of the YAPSC is also no longer active, and no one is using it so it is a dead project.

If cost isn´t that big of a concern, i would use an ODrive control board since that project is still alive and you can get support. It is a pretty good application for that case since you have an existing servo that you want to retrofit.

You would just need the 119€ control board, the servo already has the encoder.

For standalone applications i think that is a pretty bad deal since you also need the motor and encoder, and there are way better options for that which are plug & play ( for example the JMC)

You just need to check the voltage the motor runs at. I remember diffusely that the two motors in my 768 BST run at 110V, but i could be wrong. The wires are pretty thin tho.
