Trying a few images
« on: September 10, 2017, 01:51:12 PM »
Im trying to do a few mascot images on a 8x8 piece of wood and it's saying it's going to take 250 minutes to do a 5x5 inch image, is there any tips or tricks around this

What speed? B/w or grayscale?

Resolution is very important, 0.15 should be sufficient if you de-focus the laser slightly.

you could also do an auto trace then a hatch fill. It might not be as solid of an engraving but it could give the same look.  Depends on what you are going for.  In wood I like a deep engraved (almost routered) look.  So I almost always burn slow and at .1 mm resolution, but every project takes forever.  Good thing I have two laser engravers  8)

All great suggestion have been provided so far. Increase the feed rate to 3500.

I tested it as a hatch filled vector at 500 feed rate, it will take around 20 minutes.

No you won't damage the laser as it isn't actually on permanently for 200 minutes, although something is wrong as it was half that on my system using the same settings you mentioned (at 0.15 resolution).

I was showing the hatch vector option that nottingham82 suggested.

200 minutes is 3 hours and 20 minutes. I have run project up to 6 hours and have had no problem.

The only problem I have had with T2 was yesterday when I was burning a plaque. I walked away for a few minutes to answer nature's call ;) and when I came back, there was an unknown error on T2 and my laser was just sitting in one spot turned on. I am REALLY HAPPY that I was etching slate  and not wood. My Eleksmaker usb cable had failed on me and I had replaced it. Apparently, my cable was a little too slow (old Blackberry cable). I replaced it with a newer cable and the project worked perfectly. The only thing that pissed me off was the fact that the project was 93% done and then failed. At least it was one ruined piece of slate and not my house. Two lessons learned here.

If there's a data error T2Laser will attempt to disable the laser but of course if it can't communicate it wouldn't be able to. Using Dynamic Laser Mode may have helped, but it depends if Grbl was still in control of the machine.

Thanks Zax. To be honest, I don't think it was T2's fault at all. That will teach me to grab my USB cable from my car.
