Does your Laser stop half way through the burn?
First things to check:
- Poor grounding causes electrical noise
Please read this grounding advisory for Ortur for the Lasermaster 2. Free grounding kit available. - Chiller or air compressor on the same circuit as the controller can cause electrical noise or brownouts.
If you are using a GCode device with “Home on Startup” enabled, USB connection errors will cause the connect to re-establish, and the device will re-home. This is a very good indication that you have one of the above issues.
Windows Software Issue:
A very common problem with Windows systems and lasers is the way Windows handles USB connections – If it thinks a connection is idle, it can put the port into a power-save mode, which can make your device stop talking to it. This is especially common with laptops.
If you are having issues where you often lose the USB connection after a period of time, try the following:
How to disable Windows 10’s ‘USB selective suspend’ setting
When a USB device is not working correctly with your Windows 10 PC, you can try disabling the “USB selective suspend” feature to fix the problem. Here’s how:
Windows 10 includes the USB selective suspend feature that lets you automatically put USB devices in a very low-power state when they’re not actively in use. It’s an important feature because it helps prolong battery life on your laptop or tablet, but it may also cause problems with certain peripherals connected to your PC.
If a USB device isn’t working correctly, you can try to disable selective suspend on Windows 10. That may cause your computer to draw more power, but it may help to identify and fix the problem as well.
In this Windows 10 guide, I will walk you through the steps to prevent the OS from suspending USB devices by changing the power options in the Control Panel.
How to disable USB selective suspend
If you’re having connectivity issues with USB peripherals on Windows 10, use these steps to disable the USB selective suspend feature.
Important: It’s only recommended that you change this particular setting when you’re experiencing problems with a USB device. Otherwise, you should leave the option enabled.
- Open Control Panel.
- Click on Hardware and Sound.
- Click on Power Options.
- Under “Preferred plan,” click the Change plan settings link for the plan you’re currently using. (If you change the settings on the power plan that isn’t active, this won’t work.)
5. Click the Change advanced power settings link.
6. Expand USB settings.
7. Expand USB selective suspend settings
8. Select Disabled from the drop-down menu.
9. Click Apply.
10. Click OK.
If you’re changing the settings on a laptop or tablet, you’ll see two options: On Battery and Plugged in, so make sure to change those settings accordingly.
Once you complete these steps, Windows 10 will no longer power off USB devices connected to your computer, which can fix the problem of the laser turning off as a result of this feature.
While this guide focuses on Windows 10, USB selective suspend has been around for a long time, and you can use the same steps on machines running Windows 8.1 and Windows 7.
Or perhaps it’s time for a new computer?
this was so helpful been looking around for proper help. keep up the good work for us computer beginners
I had this issue. It turned out to be a power supply issue. The OEM supply wasn’t up to the task. I purchased this one and haven’t had a problem since.
