I recently bought a new 100 watt laser and sold my old 60 watt machine to a friend who is not at all mechanically inclined. While helping her align the mirrors, I moved the laser head to various positions. In the Y direction, away from the limit switch, the the head wanted to keep moving and after hitting escape, it stopped grinding and would not move. The Y limit switch alarm LED is illuminated. Not sure if this was a limit switch problem, I asked her to restore to a backup. She said there were no backups and the controller asked if she wanted to restore to factory default.
Can anyone give me their opinion of what we can do the next time I’m with this machine. I did buy a replacement limit switch just in case.
Stay away from resets on these controllers. If you do a factory reset, it goes back to whatever Ruida set them up and not what your vendor has set up.. In other words you can loose all the settings that make your machine unique to that vendor.
On the sensor or elsewhere?
On my Ruida, which is a 6442g, there are leds on the controller and I can use the console via Z/U → diagnosis to see what the machine sees.
This is from my machine and shows the X home switch is active and the water protection is active.
These are generally Hall effect sensors and trigger when a Ferris object gets close enough.
If there is nothing near the switch, it should be off. You can usually find the X switch so you can see if they are working in the same manner… Like is Y stuck on all the time?
If it’s stuck on, then you’ll have to pick up a replacement from Amazon or something. Most of these are NPN type switches or an open collector, hall effect. This is from my machine.
OK, I’m back.
Now I have 2 problems. The Y direction still grinds on start up and can’t be moved. I tested the limit switch, didn’t light up. I changed the switch, still same problem.
When I first got to the machine today, I tested the X switch and it lit up. Now the laser head will traverse to the left but stops half way. Now this switch also does not light up.
When traversing the laser back to the right, it also grinds backed up from file on a date everything worked. Also, no help.
I’m think8ng power too. Both X and Y "grind at the far limits of travel. Could it be 5he controller? I think it’s strange that this machine has no backups. I had a copy on my laptop and loaded it to her machine without effect.
If it’s getting power, I’d think the hall effect switch would detect it. Ensure the switch is powered up, it should have three wires - ground - signal - power.
