If I understand correctly, you removed the Nano from the new board and plugged it into the old control board?

You probably need to install the firmware (which depends on the software you're using) and then configure it.

No problem for me, it helps others looking for solutions... once we figure it out of course  ???

Yes. Looks OK on the simulation "view" and engraves correctly.

It's at the start of each polyline, so when the laser switches on.

You can use any Nano clone, they're available from many sources.

Does your controller board have extra holes on the Nano socket?

So your problem isn't unfinished cuts as much as it's the laser isn't turning on correctly, you have a delay in getting to power which indicates the laser driver isn't providing enough start up current.

Power supply issue perhaps?

That looks like a bed of nails... painful!  :o

Very cool idea though, and nice execution.

Can you control the laser via software?

You said it's a new board, did you load the same firmware you were using and do you get the Grbl welcome message?

I don't think anything needs to be changed out, just make sure you have a good cooling source. Use DI (or at least distilled) water in a closed system with a few drops of clear ethylene or propylene glycol (anti freeze). It will eliminate any bacterial growth.

The Chinese pumps usually don't last long, so a flow and temperature interlock switch on the coolant are very important, they will save your laser tube should something fail.

If you want the tube to last a long time, never use more than 90% power.

That looks fantastic, well done.

The firmware needs to match the software and your hardware, as I said Benbox only works with a custom Grbl 0.8 version. If you install 0.9 or 1.1 you'll no longer be able to use Benbox.

I wrote T2Laser as an alternate software and it comes with the COM driver and firmware as a complete package.

There are several options for the “view”, it sounds like you are seeing yellow for laser 0 power.

Resolution is usually set for the quality and speed, the “correct” setting depends on many factors.

You will see the complete result immediately, running the simulation is only necessary on vector when you want to see the paths. Yes you can change the speed.

Check the manual for all the keys associated with the simulation view.

254 dpi and 0.1 resolution is correct for sizing.

I’ve had good results with birch but many woods are acceptable.

TTL is a 5V logic signal (usually direct from the ATmega328 chip), from the looks of that board it only has a 12V output (laser/spindle) but I don't know that for sure.

If you can figure out how to tap the TTL signal from the microcontroller you could use that board.

Your laser has 3 or 4 inputs / wires? It must have a separate power (12V and Ground), and then a TTL signal (sometimes another ground for the logic rather than power).

You wouldn't use the spindle/laser connector at all as that's a switched 12V.

I believe the Endurance lasers have a TTL input which works with 12V - so not really a TTL input at all but it would work with your board without modification (at least that's my understanding, I don't have one so you'd need to confirm).

I don't see a TTL output?

Wow that is interesting, I will check the calculations - something is obviously not right. Thanks for the detective work!

*edit: I don't see the same problem, when I change vector speeds it calculates correctly... more investigation required.

I'm not familiar with the Woodpecker CNC board, does it support TTL?

Is the "15W" laser wired for TTL?

Does your software send the required codes for Grbl to change laser power?
