Hoping to get a solution to a Mach3 error on start up:

Smoothstepper v17fc: "unable to load the FTDI USB driver ftd2xx.dll" followed by a 9991 triggered error and forced close down.

Is this a Windows 8 compatability problem? Note, I had a forced Windows Op update on my laptop (been putting it off and off but was forced in time to accept an upgrade. I have had SS problems with Win 8 previously.

Best check with Greg but it could be the driver is needing updated for W8.

Did you find a solution to this issue? I'm having the exact same problem.

Hi,

Did you find a solution to this issue? I'm having the exact same problem.

This post is thirteen years old.

USB connected SmoothSteppers, USS, are obsolete, that is to say they are no longer being manufactured, in favour of the
Ethernet connected SmoothStepper, ESS.

You will find support for both the USS and ESS at the Warp9TD Forum.
