Question Using Plesk to Host a Web Interface for Stepper Motor Control

[karl25]

Hi everyone,

I’m currently working on a DIY automation project involving stepper motors (NEMA 17 and 23) controlled via a Raspberry Pi. My goal is to control the motors remotely through a simple web interface. Since I already have a VPS with Plesk installed for other projects, I thought, why not host the motor control interface there?

I’ve built a basic Flask/Python web app that sends commands to the Pi via HTTP requests. The backend on the Pi then drives the stepper motors using a DRV8825 driver.

I’m curious if anyone else here has tried something similar:

Hosting a motor control panel (UI) on a Plesk-managed server

Communicating securely between the Plesk server and a local Pi that controls stepper motors

Using tools like Node.js, Flask, or PHP for the frontend/backend

Handling remote access and authentication securely

Any tips on configuring Plesk for this kind of setup (e.g., firewall rules, SSL, reverse proxying) would also be appreciated.

Would love to see how others are integrating web tech with motion control!

Cheers,
Karl

I have no experience hosting Flask or Python applications on Plesk servers myself. But I came across this blog that might be helpful for you're use case:

Python Flask (or Dash) applications on Plesk

Although not officially documented, it is possible to host Python Flask applications easily with Plesk. The process and technologies are the same as those used for Plesk's official Node.js support.
