Hi, my name is Paul and by trade I work in IT, specifically Microsoft SQL Server. I've been tinkering for a while with bits and pieces and I'm currently trying to automate my lounge curtains. I have had a first working test running a couple of days ago, which I've taken down, and am now looking to get it done properly. I'm using a couple of Nema17 motors, an A4988 driver and EspHome in Home Assistant.

Welcome to the forum, Paul.

I'm curious why you took down a working assembly and what you mean by"get it done properly". What was improper about your (working) version ?

Anything seems possible when you don't know what you're talking about.

@spe109 Welcome to the forum Paul. It sounds like you are really getting into it, keep us informed of your progress. If/when you need to post something start a new Topic in the appropriate forum/sub-forum.

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

@will Although it was a working version the 3d printed case is not quite right, slightly too small to fit in the Nema17 (I had to do some filling) and the wires were just dangling from a breadboard, the power supplies also dangling. It was a test to make sure the Nema17 had enough force to pull a curtain. I learned a lot from my initial design, so well worth doing. Now I'd like to change the design of the case, make it a little bigger and work out a position for the electronics, which also need an enclosure.

Ah, now I understand, thanks.

So it was more that the "packaging" was deficient than a problem with the electronics.
