Hello all and thank you for the time you spend to read my thread.
I am Alex from Romania.
I am watching this forum for a long time and read a lot, from this forum i got ideas and bulit a cnc router 2 years ago, it's a beast 2x1.5 meters nema 34 stepper motors 2.2 kw spindle, it works nice and had no issues with it also built a lot of cool stuf with this thing.
Regarding the router i wanted a co2 laser, because i had no spare time any more with my job and small bussines in woodworking and props, all beacause of you guys
.
So i had bought on ebay a co2 laser 130w 1390 from Vevor
.
I worked the hell out of it for the last 7-8 months. until hell broke lose and came to my laser. So here are my problems.
From the begining the lower right side of the table it wouldn't pass through the material all the way evrey time, or it had small points were it would't pass al the way through, it didn't botther me as i had the rest of the table to work with.
Now the only place that it passes all the way through is the left upper size of the table.
I did the following steps to figure out this problem.
Aligned the body of the machine so that is leveled as much as i could because the chasis was not welded right it will never be leveld perfectly, it has a warp from bottom left to upper right.
Aligned the tube, mirrors, so on my 4 corners of the table the dot is spot on the center of the third mirror
Aligned the lens so that the beam is perfectly perpendicular with the last mirror
I did these steps probably 4 or 5 times now maybe more
The honey comb is perfectly leveled and paralel with the head precision is about -0.2/+0.3
To me it seems that the laser still punches power but if i test a piece of acrylic on the left part of table and right part of table, same material same power no lens on. I press the pulse button and keep it presed. in the left part of table it passes throuhg it in 5 sec while in the right it passes it in 10 sec.
Oh and also changed mirrors and lens, same results.
If anyone somehow may help me with any info any ideeas i'll apreciate that.
I don't know what else to try or due. I'm out of ideas and i need this laser to work.
Also if anyone in Europe from who i can buy spare parts for the laser hope for god no tube or power supply )
Thank you all
Let's crack the problem.
