I recently purchased a new 80w co2 laser from YorkLaser in China.
The company were most helpful and promised to provide technical support as required. When the unit arrived the fun started. (luckily i have extensive engineering experience as the build quaility is shocking). The first issue was that a foot fell off as w lifted the unit off the pallet (the welding was one-sided). then i found that they forgot to pack the 1200mm x 900mm honeycombe cutting bed. The third issue was that the Laser beam was firing into the first mirror 8mm above centre. There is no available adjustment for this. I managed to calibrate the beam through the cutting head but the power was down by 50%. I wrote to York Laser and enclosed photos of the mis-match. They responded with "do not try to fix, laser may still work". I cut my own spacer from 8mm acrylic to raise the primary mirror block up, then re-calibrated the beam and had twice the power. During calibration noticed that the lens appeared to have damaged coating. I had ordered a spare lens with the machine luckily so i installed that. Then i found that the beam was cutting off-square. To fix that i had to remove the cutting head mounts and slot 3 holes to get enough adjustment. Then i found that the rise and full bed was 10mm lower on the right hand side. I had to remove the belts driving the threaded rods to level the table & thats when i found all the fresh swarf still emdedded in the threads! Once i rectified the above issues I decided to test the rotary attachment. First issue: nowhere to plug it in!
the machine is fitted with a 4 axis controller but only 2 stepper motor controllers had been fitted for x & y axis. I wrote to york Laser with my concerns and requested a replacement lens & another stepper motor controller for the u axis. The response: "just unplug the y axis & plug rotary attachment into that". Then i discover that the software was written in the 1900's! It is diabolical. During testing the led focus unit died. I wrote to York again requesting a replacement lens, extra stepper controller, replacement led unit and pointed out that my honeycombe table had still not arrived, but now york will not respond to my emails (i have sent 3 in the last 2 weeks). I have been dealing with "Richael" & have no other email address so if anyone here has contact info for the company manager or similar that would be most helpful.
