The suspense is killing me  ;D. (hopefully there are more items in the pros than cons columns)

Happy Thanksgiving (aka American Christmas in my house).

Maybe you can print something appropriate and functional:

Enjoy the holiday!

Laser Modules / Re: broken Board
« on: November 22, 2017, 06:27:08 AM »
If you are unsure how to compile the firmware why not use one I include with T2Laser, the non-PWM version uses D12 and the default Grbl 1.1e (in the Machine menu) uses D11.

Set Laser Max to 35, that's what T2Laser does automatically when choosing the EleksDraw but in this case you would need to do it manually after enabling servo mode from the menu.

That doesn't sound good, sounds like the driver is/has failed rather than the diode but either way a replacement TTL module is probably a good idea! See if you can get the newer Eleks one.

It sounds like a 2-wire laser, if so you can connect it directly to 12VDC and see if it's dead or not. It sounds like it is, but best to check it.

T2 Engraving / Re: Power supply?

ggallant571, I remember we discussed this before and your laser seems really inefficient based on my testing, although perhaps that is true of all the 5.5W models.

I have a couple of 2.5W's and they consume ~0.4A, and a 1.6W that needs 0.25A.

Mini CNC / Re: Mini mill kerf

I have several CNC machines but have never used tool compensation on the equipment. I prefer to do it in software and have been using TurboCAD/CAM for years but as their upgrades get increasingly expensive I started looking at alternatives. Estlcam is a cheap solution although the user interface is a little awkward for me.

You can offset manually in most CAD programs, so technically you can create the same yourself but it's much easier to use a CAM program.

I hope they are ok.

The output from a laser diode is narrow band, so these OD6 glasses are excellent protection.

Is your concern the safety glasses or your fingers when adjusting focus?

T2 Engraving / Re: Power supply?

2.5A * 12V = 30W, which is enough for the laser but not if itís also powering the motors.

Benbox is very old and unsupported, it requires an obsolete version of Grbl 0.8.

You can test your machine with T2Laser and Grbl 1.1e firmware to determine if it's working correctly.

T2 Engraving / Re: Tablet or Laptop
« on: November 20, 2017, 04:38:05 AM »
I use a Windows 10 tablet to run T2Laser (also used for testing every new release).

It has an Intel Atom processor and 2GB so nothing fancy. I got it from Walmart during BF last year for $60 (has a detachable keyboard which is nice).

The one in your link should work but looks like it charges via USB so as Lob0426 said that may be a problem on longer engraving jobs, if it goes into power saving mode. Some tablets don't allow you to completely prevent it.

Iím surprised it had to come back and fill in some ďgapsĒ but when writing the optimizer code I thought several times it was wrong but each time I couldnít do better. In the end I decided it was best not to argue with the computer!

That makes sense, Iíve seen similar before although not bands.
