Win7 security update issue with parallel port
« on: March 18, 2018, 12:04:32 PM »
I just resolved an issue with an MS Window 7 security update (KB4088875) that was causing the parallel port to reboot the PC and I'm asking whether anyone else ran into this problem or has any additional info.

The problem manifested itself just like what's described in the documentation when you neglected to immediately reboot after a Mach3 installation. The security update was published on 3/13 and the MS page indicates a number of known issues that they say are being resolved. The PC did the same thing when running Driver Test - rebooted as the driver was 'taking over.'

I removed the update and then removed Mach3, including manually removing the driver, and then I reinstalled Mach3. Runs fine now (but I have to reenter all the settings).

I have a Dell Optiplex 780 with a second parallel port, Win7, Norton Security, but very little else on the platform as this PC is dedicated to the mill.

Comments welcome!

Get rid of Norton

The pc should be isolated anyway and Norton is one of the most aggressive/invasive A/V systems out - you will need to get the Norton installer from the site.

Once Mach is running ok, do not install any updates etc - the PC becomes a machine controller, frozen in time, pretty much like Mach3
Bridgeport Mill, Mach3 V062, CSMIO-IP/A controller, AC Servo Drives.

Hi Kirbee,

As Dave has said...

Your CNC machine should be controlled by a dedicated PC which is not internet connected, network connected or running any other software in the background.

I have the same problem , caught me while setting MACH3 :), I have to solve the problem!
I installed win 7 from "0", I let him update himself, bad idea.

FWIW - as suggested I removed Norton and took the platform off my network - everything is still fine. I do all my design and G-code generation on my office platform and I was a little lazy by trying to avoid sneakernetting. Nice try. Thumb drives are a way of life.
