Drop in 3D printer application


#1

Hi Folks, I love the odrive close loop performance. I’m researching a large scale 3D printer build, and have to date been considering a ustepper as it’s a drop in replacement in a marlin firmware printer.

It’d be awesome if you could provide drop in code as per ustepper to allow its seamless 3d printer integration. I’d definitely be up for a couple of boards and 4 encoders if I could use them in my application.

Any thoughts would be much appreciated.
Many thanks

hey @cncmodeller, I’m currently working on a large 3d printer that uses odrive, I’ll probably place the project on hackster when I get some time, I’m planning on using the same control board with step/dir interface to odrive, that way it should be a drop in replacement to steppers without changing any firmware

I don’t think that’s required. The ODrive should work in step/dir mode as a drop-in replacement already, without any code changes. You just need to configure step/dir mode with the odrivetool.

Ok thanks. I’ll place an order for a 48v board when they are back in stock.
Many thanks

Hi all, how is the 3D printer application going? I was actually wondering if a larger HangPrinter version could use broshless motors with oDrive.
I am also working on an application similar to the HangPrinter. It is about controlling a strings-attached load in 3D space. You can use it for 3D printing, you can use it as a replacement for the CNC frame of FarmBot, you can place a camera on it, … These large-scale applications don’t require high precision. But we will eventually run into some problems that the HangPrinter community has run into in trying to manage 3D motion of a load hanging on strings.

So we are trying to create a closed-loop motion control system using the actual position of the load, from distance sensors.
We’ll take a month for this sprint to a first prototype. We don’t want to reinvent the wheel, we would like to collaborate with anyone who has experience in the field and release everything as open source.

Hello I’m novice can you give us some examples to get to connect the Odrive on a 3D printer. Wiring plan and code changes thank you very much

Hello I tried to follow the procedure see the picture attached but I can not run the M0 engine when it is connected to my Arduino Mega 2560 + Ramps 1.4 I recovered the dir and the wire step in gpio 2 and 1
do you have an idea I do not understand why it does not work so with the Arduino test procedure it works fine
thank you
