opengalvo / opal Goto Github PK

Hi there,

first of all thank you for this repo, i was waiting for this for a long time now!

I purchased a RC1001 type galvo recently but these "analogue" ones are not covered here.
Any chance that there is a way to drive these type of galvos with a microcontroller, like teensy or driving these is fundamentally different?

thank you in advance!

First of all, this project is awesome! Beautiful work! Exactly what I was looking for!

When I Scoped the Tickle pulse, the width is too short for a Synrad 48. It should have a width of 1uS
Easy fix, in lib/LaserController/Synrad48Ctrl.h line 54 change this
const static uint16_t ticklePWM = 4;
To this:
const static uint16_t ticklePWM = 20;

I have also drawn a schematic and produced a PCB design for this project, and am happy to contribute it if you like. Also do you mind if I showcase this project on my YouTube Channel?

Thanks so much for this wonderful project! I finally have things all built and ready to try out.

I did need to move all the source code files in "lib/" out of their sub-directories and place them into the "src/" directory for the Arduino IDE (v2.2.1 on Ubuntu Linux) to see them. Then I needed to change some #include directives to use quotes instead of angle brackets, and had to fix a couple "helpers.h" includes which need to be "Helpers.h" in Linux due to the filesystem being case sensitive.

It might be worth at least fixing the "helpers.h" / "Helpers.h" issue, and it would be super cool if the directory structure could be fixed somehow so that things work out of the box without having to move the files around.

Anyway, thanks much for the great project!!

First of all, thanks for providing this amazing tool. I'm relatively new to Arduino and hoping to get some help.
I need some help on hardware wiring and config instructions. How do I config it to a regular laser instead of the Synrad laser? I hooked a scope to pin 6 (the laser PWM pin?) and got some periodic pulses coming out, which doesn't make any sense to me. Isn't that going to trigger the laser? I also see pulses and waveforms on the other 4 pins; I tried to send command to the Teensy and got "ok" coming back to not seeing any meaningful changes on the 4 pins. Am I missing something?

Thank you!

Laser turns on and off delayed by what seems one move.

At the very beginning, I also have to say: WOW. And thank you. :)
Four years ago, I started writing an implementation of the XY2-100 for the Arduino Uno platform. I know, I know - 16MHz ;)
But I was able to finally reproduce all the signals on the outputs. I converted G-Code to an array of bits, which I then sent to GPIOs. Unfortunately, I abandoned the project because I felt that this was not the way to go. Then I thought about using I2S protocols or DMA interrupts, but finally I gave up for lack of time.
I have already ordered Teensy and I am looking forward to testing your project. I have powerful, 120W LED lasers from DILAS. I also have a 100W CO2 laser from Coherent. I need to test this with my scanner head :) Necessarily. :)
Best regards

Please make the code please

Running some , especially long, files cause the device to hang.
