I read all topics chuck rotary tool issues related and nothing helped me. So that´s why I decided to open one.
Laser engraver machine HL-1060S 80W CO2
Controller: Ruida 6445G (version 30)
Chuck rotary tool OMTech
A brief explanation of the issue: The engraving looks like if the line interval were too high. The image looks like deformed.
I´ve made several test decreasing line interval from 0.01 to 0.001 and the result is the same.
**Note: without rotary tool, the cutting and engraving in the machine is normal, no issues.
The steps per rotation I´m using for a 77mm object diameter is 12,697.12
**Note: when I create a square 20x20mm, the height is correct 20mm, but the width always have a difference of -1mm (19mm instead 20mm) no matter if it´s a cylindrical or conical tumbler.
What I realized while making tests is that in certain position, what supposed to be a straight line, it makes like curves
Note: I removed the chuck rotary cover to check if the pulleys spin freely and it wasn´t any problem (clockwise and counterclockwise), but I noticed when the rotary is plugged in the laser machine (turned on) it feels like small “vibration” when I spin the chuck rotary head with my hand. Not sure how to explain it. That feels like if the pulleys had grains of salt or something like that and couln´t spin freely.
In some position, the square have straight lines:
Then I realized in another, the issue comes into play:
Note: Look at the last picture, in the upper left corner, the laser missed a segment of the square.
I keep reading and making tests, but It´s been a long time since I bought this tool and I can´t resing to this won´t work.
Any help would be very appreciated.
