Power saving settings for USB machines and Win7

Post by Denford Admin » Thu 23 Jun , 2011 13:39 pm

This document shows you how to alter the power saving settings on Windows 7.
Adjust the settings for reliable USB communication between PC and Mill, Lathe, Laser or rapid prototyping machine
Try this if you find the machine times out or you get timeout messages after a certain time - you're more likely to see it on a laptop or "green" desktop

Hardware/Software: Hi

I am running a VLS 3.5 with extraction unit below. The extraction unit has started to make a strange sound about 30 seconds after it is turned on. It sounds as though an internal fan is catching on something inside the casing. After looking the the maintainence manual I am none the wiser about how to tackle this problem. The filters do not yet need replacing.

Any suggestions would be greatly appreciated.

I tried altering the power settings but the same issue arises. The machine is disconnecting before starting to cut.

Could the firm ware need updating to communicate with windows 8? which is running on a macbook.

The machine works ok with windows 7 on a Dell machine.

Is this on a laser?

Are you using a laptop, if so is the power supply plugged in?

Have you tried other USB ports on the computer?

The USB port you are using is probably not providing enough power to the machine. You may need to use a powered USB hub.
