General Discussion / Re: Compressor for direct air
« on: February 03, 2018, 12:39:26 PM »
I got the same compressor as Ralph with my CO2-laser, but I am going to use it with my LED-laser, while I have bought a bigger compressor for my CO2-laser.

Benbox / Re: A3 PRO 5500mW cuts deeper when only moving in Y-direction

I do not use Benbox software, but mostly BenCutLaser and sometimes T2Laser. Both these two programms lets you easily modify the speed in each direction.

I have the same problem with my 3500 mW laser and I have adjusted the speed in the different directions, so the cut is even in X as well as Y.

Cutting / Re: Laser focus ?
« on: November 11, 2017, 01:14:59 AM »
I have a feeling the distance is not the question. The focus is more important. As long as the laser is fully focussed, the power is there concentrated. The size of the final spot can differ from laser to laser and in my case a 3500 mW laser is less effective than my previous 2500 mW laser, as the spot of the 3500 mW laser is bigger and therefor less concentrated.

Hi Ralph,

All is well. I did install 2.7b this afternoon.


Trouble Shooting / Re: Diode probably died.
« on: November 01, 2017, 02:24:11 PM »

I did get a lot of work out of this diode, but unfortunately it is just before I was going to give a demo in about a weeks time. It is just an awkward moment to die.
There was no sign before.
I think the diode has been running for about one month, when I put all output together, so 30 times 24 hours = 720 hours of burning over a period of about one year.

 I'll see what I use as replacement. I should have another 2500 mW laser somewhere, but I cannot find that one at the moment. I also have a 3500 mW TTL laser, so I am thinking of using that one. That means I need to use another baord and recable my frame as this one was fully hardwired. I have various baords, which I can use, that are all with connectors, so I can switch. This was in preparation for my bigger laser machine, but due to the movement of house all is a bit in a strange order everywhere.

Thanks for the tip on the 1600mW laser as Ralph also has good findings with that one.

Hi Folks,

I am using a standard 2500 mW laser without TTL.
Yesterday I did make some nice cuts.
Today I started the laser and the power is almost gone.
At some lines it is very fainted. At others the laser wil not even light up. The power is there as the fan of the laser is running.
I think I need to put another laser in my frame.

Hi Ralph,

No problem.

I am back after a long time of no use, due to moving house.

I am running Windows 10.
When I unpack the version 2.6b and run Setup, I get the following error:

System.IO.DirectoryNotFoundException: Kan een gedeelte van het pad debug.txt niet vinden.

My current version of BCL is 2.5b

General Discussion / Re: Longest run without stopping

I have done jobs over 48 hours to cut 12 mm multiplex.

I am just in the process of starting up again as I did move house.

Hi CherryMan,

Welcome on the forum.

It is difficult to see what board is being used. May be you can ask the vendor. Also ask about the Grbl it uses. Most of us use Grbl 0.8 or higher, like Grbl 1.1f.

The software for etching for me is T2Laser and BenCutLaser for cutting and etching.

Kind regards,

I have a feeling the CNC-cutting is a strange order. Why not deep mill each compartment at a time, and at the end mill the surrounding rim? This would be done relative easy with some simple G-code.
I think it is a lot faster, than a kind of raster as you have done at the moment.

Thanks for sharing.

Are there any pictures of finished results?


Trouble Shooting / Re: Problem cutting plywood

I have also noticed, that it is sometime more effective to do single passes, but repeat the process multiple times. It is not only the heat dissipation, but also the heat stays a while and when the laser returns to quickly the material is still hot, so by returning after a while the material at that place has cooled down.

I did get too large burns at small holes and no cut through at larger holes. By repeating the lot all was more evenly distributed. Also as Ralph says the grain has a lot of influance. Also the surface of the material has a lot of influance. When it is too shiny, or too polished, the laser will be refle ted more.
