Perfect circles but letter gibberish
« on: November 11, 2017, 06:18:56 AM »
Dear forum

I have an issue with a Benbox Laser engraver. I have tried to engrave some viking runes (see attached picture) on a piece of thin plywood. It looks like the speed etc. is right, but it turns out quite different... (see attached picture "gibberish") It can't engrave plain text either. But circles and squares work just fine.

What could be the issue?

We need more info about your laser machine.

What controller board?

What firmware are  you using?

Who did you buy your laser machine from?

Hi

The laser engraver is a Benbox BIQU 2500 mW bought on Amazon. I believe the controller is a Rasberry Pi Nano. The firmware came on a USB with multiple different versions. I have tried nearly all of them. The last one that I tried was named "NANO(328p)/LX-NANO"
What firmware should I be using?

Thanks for your help!

Can you do the following:
1. Post a link to your Engraver (could not find it)
2. Take a picture of your controller board (front and back)
3. Take a picture of your machine
4. Tell us what software you are using

It looks like a LaserAxe clone https://smile.amazon.com/BIQU-2500mw-Engraving-Machine-Engraver/dp/B01HCX191G

Since he's using the Benbox firmware I would imagine he is also using Benbox software.

It's not a Raspberry Pi, but an Arduino Nano clone based controller running Grbl firmware. The Benbox software and firmware is very old, but it should still "work". I don't know what to make of your result.
