Laser Engraver Forum

Hello!

Nobody replied. So, I wrote the same post here.
You can check the photo through my last post.

I have three questions.

1. When we cut the Acrylic sheet, it seems something sticking out of edge. So, the edge is too sharp.
And, when we touch the edge we feel rough.
I do not know I explain plainly or not. I am attaching the drawing to explain the edge.
The ruler you offered does not have sharp edge. It is smooth even though the edge is 90 degrees.
It seems that there is something on the edge.

2. When we try to align the mirrors.
We cannot make small hall. We always have small circle burning mark.
On your movie clip, you made a very small dot.
Could you tell me how to make small dot. I am attaching photo.

3. You had said to remove the level sensor to solve not moving Z axis problem.
I disconnected the sensor and then the problem solved.
Does it mean the sensor has the problem?
Can I keep using the machine without sensor?

Thanks in advance.

Hi Young
Sorry reply you so lately cause we were out in the weekend
For your questions
1. Could you please take a picture about the cutting result to show me and also sending your file to me for checking
It's just a drawing graphics, a real cutting result will provide me more details

2. align the laser beam, please set that power to 25% even 30%, it will shows you a filled circle,
and the video shown you that is a 40W laser tube, but your laser is a big laser tube, so the laser dot will be also larger
It's difference with two type of laser tubes
how many power you set when you align the mirror?

3. the auto focus sensor is unreliable now, maybe its detecting area is dirty, after you cleaned using the alcohol and the issue is still
Please keep using the laser machine without sensor
