Hello,
I have a ULS PS25 laser engraving system with an intermittent issue. The problem that I am seeing is that sometimes the Y-axis does not want to home, and sometimes stalls during a raster job. If the gantry is placed in the middle of the table at the time of homing the Y-axis does not want to home at all. When the Y-axis does not home, the back 2 red led indicators are not lit (total of 4 red leds, back 2 not lit) on my gold colored power supply. With power off, manually moving the gantry back and forth through the range of the table feels smooth without any binding. I am able to home the machine succesfully if I position the gantry (Y-axis) near the home position before the system initates the homing sequence.
After the system does home, I am able to cut parts without too much of an issue. I've had the Y-axis quit working, or stall once in the middle of cutting a part. I was able to shutdown, re-home with Y near the home position first, and run several jobs succesfully afterwards. The last time I've run the machine I had an issue with homing, but once it was homed I was able to run without any issues. I ran 6 different cutting jobs without a glitch over a period of about 6 hours. The gantry was moving over the whole area of the table during this time. Also, I was cutiing 3/16" acrylic and my speed is set fairly low around .6 inside the ULS Windows driver.
The issue is worse when trying to raster as the Y-axis likes to stall more frequently in the middle of a job. Meanwhile the X-axis continues to run, along with the laser. Needless to say I don't walk too far from it when it's running. Sometimes I can raster with no problems, but I am at the point where I don't really trust the machine to be able complete a raster job successfully. When the Y-axis stalls, both of the back 2 led indicators are not lit on the gold colored power supply. The fan on the unit is working.
Anyone have any inputs as to where my issue might be? I'm positive that it is my power suppy malfunctioning, but I was looking for reassurance...
