@edwawr Can you jog the laser with the arrows?

I don't see the connect string, are you using my Grbl 1.1e firmware?

What happens when you click the send envelope?

@DavidF The air assist adaptor is screwed on the laser module. The laser itself is not the original. It's a "15W" module from banggood. (look the pic below). It was 3D printed.
I'm using a airbrush compressor for it, but the one I have is very noisy.
Next week I expect to receive a new one, less noisy.

Yep, very happy bunny at the moment. All is working well. Homing switches arrived today so I'll get those fitted.
Had great success cutting that dxf in 4mm ply. 3 passes at 150mm/m. Surprised it did it so easily. Air jet really makes a difference.

Cheers

Hi Zaxs, I did load 1.1e at the beginning. I didn't realise that "Configure eleksmana" over wrote the firmware, it certainly wasn't intentional. I assumed it might be for table size, laser type or motor types etc. So the answer is to reset everything to default, reinstall 1.1e and DON'T select that option:-)

Cheers,

David

@Elvs-Bearzi All of the K40's are similar. You should expect to spend another $200~300 on upgrades to get a good machine.

@davidwoodworker There are many options for software, I wrote T2Laser as an alternative and provide support for it as well as constant development. EleksCAM is obsolete (only works with the older firmware) and unsupported (has known bugs that aren't fixed).

The Nano is a standard device with many alternatives, they are plug and play replacements. I have used Geekcreit, HiLetGo and others with good results - these all use genuine ATmega328p microcontroller's which are more reliable than the Chinese copies.

@hoptho I agree it’s likely the laser is bad, but I would also check the lens is in correctly (if it’s backwards or not seated flat you may get this symptom).

@wopak I would buy the EleksLaser with the draw module, but it really depends on your application. If you intend to do a lot of drawing and rarely use the laser then that would change the decision.

@Thomas-Valloo This is a perfectly reasonable method using a micro-switch or magnetic reed switch.

@JayC Any Arduino Nano (or clone) will work, you should be able to purchase locally but of course I don't know where you are located.
