New Open Source Turntable

Post by Micr0 » 15 Dec 2019, 20:29

A very nice, complete 3D printable trunion design with a Raspberry pie controller. The guy even sells all the parts if you don't want to source them yourself.

One wonders if this can (easily) be adapted to use the AutoIt-solution that i use.
From memory I need an "S" sent from the turntable on the COM-port when turning is done to trigger the next scan.

Will investigate.

I was not able to fully automate the scanning process with a simple turntable through AutoIt, because I could not get Deviare to work (intercept the end of the scan in HP3Dscan). And without fully automating the process, it’s personally for me, it’s easier to manually rotate the table or object on it.

I'm into the AutoIT/Arduino stuff.
I'm not using an ADAFruit motor shield, but a DRV8825, connected as report here: https://www.makerguides.com/drv8825-ste ... -tutorial/

The motor is moving correctly with a sketch that does not require a serial.port input (motor_only).

At the moment I had the Autoit script working while connected with Arduino, (making a selected number of scans, but before every scans there's a window with timeout error, see picture), not giving Arduino the right command for moving.

Any suggestion?

I attached my AutoIt code (7-zip) and the Arduino Sketch.

Well,
a mistake could be missing first line:
#include <Wire.h>

but that did not change the final outcome.

After minor modifications... IT WORKS!
(well, at the moment it does not stop at 40 scans, but at least it goes on forever)

This thread is interesting :-)

I bought the openscan-kit (PCB preassembled/programmed) . To fun not to try ;-)
I will modify the Arduino sketch to function with the AutoIT-solution.

Report in a few weeks I hope.

I have a similar solution. Only I added control by pressing the "s" button - i.e. I run the AutoIt script, press "s", the table rotates and scanning starts. After the end of the stage, I press the button again. I was programmed for 10 turns (I also had to make my own * .ino - because the table is controlled by my existing HE3D board from the Chinese version of the Ciclop laser scanner)

I'm sure Martan will do a great job!
Keep us updated!

My sketch works in receiveing char 2 and sending S, so it's a great step ahead for my use.
I can do other things and let the guys work for me.

Another interesting project: www.photopizza.org

I made one a couple of years ago, but with a different control unit, with real bottons.
The new version run on espruino. The user interface is very interesting.
