I have a Trotec Speedy 300 that is a little over 3 years old and is a great machine but over the past month or so I've been having a issue where the laser beam loose its position on the table as it is engraving. It is almost like it is skipping a tooth on the belt as it move down the table (see pic). It only occurs if I run a job that is over 16-20" wide and at a higher speed like when engraving acrylic, if I run at a really slow speed like in stainless steel the problem has not occurred yet. I can run jobs all day long when I keep it under the threshold and never have a problem. I've check the belt very closely and have not been able to find a area that the belt has worn down to cause this issue. Talked to Trotec Tech and they suggested to check and adjust the X Axis belt tension, which I did, no change. They said if that did not work it was the stepper motor, which I find hard to believe since it runs with no issue under that 16" threshold. I was also told that to have someone come and service the machine the cost would be $2000 plus any parts. That is just ridiculous since there is a Trotec office 1 hour away, so I told them no thanks. Has anyone else had this issue or can offer some suggestions I can look at to resolve this issue. Thanks in advance.
