SBot acting weird

[woodshopcnc]

Have been using my SB for 3D Carving and signage.

Some of the carving files are 5 - 7 hrs long. The machine will start off carving fine, for a little while (1 - 3 hrs), then I run into problems. The SB will either start carving about 1/4 of the original speed or it will will start to bang (as if the ramp values were messed up)? When it banks, the carving is not as sharp as it should be.

If I stop the file and resume the speed is back to normal and usually it does not happen again. This happens on every file that is a long carving type.

I went into msconfig on the laptop that I run the sb on and shut down everything I can think of and set power to on all the time (no hibernate, etc).

I also loaded the new software and have hooked both usb's direct to the computer without the hub, but the problem is still there.

Can anyone help me out on this?

Sigh :( Let me guess, version 3.8

I've seen that also. Be sure that there are no programs looking to auto update themselves also. That includes windows and antivirus. Get rid of any Adobe PDF readers (free Foxit Reader is fine for help documents etc. and set it to not update) Although MicroSoft Security Essentials has gotten a bad rap lately, it's fine for this and light weight if you can't do without antivirus. Any interruption to data flow can be a problem. Can't say that this will fix it for you though.

Doubt many are using XP anymore but here (http://www.joesboats.com/sb/FreeResources.htm) is a good slimdown that will have excellent takeaways for win 7. I will have to make a windows 7 and a windows 8 version.

fwiw

Especially heed this:
Under the View tab of the Folder Options dialog box, in the Advanced settings list, deselect the Automatically search for network folders and printers checkbox, then click the Apply to All Folders button: (This will eliminate the machine from attempting to locate 'stuff' on its own and making the system stop responding for several seconds each time.)

This is just a thought...on my home computer this happens and it might have some bearing...
Normally when i'm done on my computer i just put it to sleep till the next day but after 2-3 days of opening apps, ect i think a lot of my memory gets used and things slow way down and i have to just reboot everything to get that memory back.
Maybe if you reboot everything prior to starting a big 3d file that might help?:confused:
