Streaking Problems

[Bert Kemp]

Was engraving a tile and in the middle of the picture I got about an inch of streaking like the laser wasn't firing properly. Power was 100 speed was 30. Any Ideas

There have been some issues with FS lasers where the assembly was rather hasty and parts weren't secure. I don't know if that's the cause here but I would run a complete maintenance check on all parts including the table. I know of two such instances where the table had not been secure. Another where the lens assembly was loose.

also look t the picture and make sure there is nothing wrong with it

Whew...when I read the subject line, I thought the '70s had come full circle...

Do what mike suggested first. I had a lot of issues due to loose parts and also my table wasnt leveled.Its also could be due to bad grounding.

Is it a constant random problem with any raster file you try engrave? Does it happen at the same place on the table?
I think you need to revert to FSL , it could be anything that's causing that streaking , but if I had to hazard a guess, looking a the constant pattern evident thru the streaking bit , I would say its related to the control board software or the tube misfiring.
