General Mach Discussion / Installation problem- "No Driver sensed installed"-

« on: December 14, 2012, 11:29:24 AM »

I am installing Mach3 on a Windows 7 64bit PC and I get a screen that says "No driver sensed installed. Run driver test."  After hitting the yes button it goes with no noticeable delay to the installation finished screen but the program is not engaging the steppers.  I've retried from the DriverTest.exe file with the same result.  Any ideas about the cause of the problem?

Hood,
A student discovered the problem.  Our Y axis homing switch was damaged and I guess was constantly in open position and causing the malfunction.  The student assumes that when homing the machine just activates one switch at a time so the Y switch break wasn't detected until that switch was activated after the Z had finished its operation.  In retrospect it makes complete sense.  He simply tested by separating the wires from the broken switch and the homing operation continued fine after the Z homed.
Thanks for all the help though.  It's all a learning experience.

I will have to look into that.  Again, I'm pretty ignorant about the electronics but I'm trying not to be.  I'm using a Bob Campbell breakout board and I've attached a photo of it.  Can you tell if there's a spare input?

Here it is.  I'll be done for the day soon.
Thanks for all your time.

Hood,
The switch is NC and I 've tested it as you suggested.  I guess I don't understand what's going on because the switch works when tested for continuity.  When I start homing with the wires shorted the Z moves toward home and when I pull the wires apart it reverses direction, and when I put them back together again it trips the reset.  I also experimented with different debounce setting with no apparent change.  What exactly does that tell us?
Ever been to Penicuik?  I've got some friends there.

How could it be the switch if the switch is clearly being activated (causing the software to tell the motor to change direction) and the reset isn't tripped until the Z has moved a distance away from it?

So I just played around with the debounce.  Setting it to a much higher number I could see that it was hitting the switch and then reversing direction for a while but even up to 10000 it would still trip the reset on the way down.  The higher the number the great the distance it would go down.
What's it all mean?

No, I can reset and manually move all axes.

Russ,

It was at 14, I changed it to 500, but it made no change in the problem.

The machine has steppers.  A student had the idea of reducing the velocity and it hasn't seized up while rapiding since then.  We haven't run code yet though because we're having a new problem.  When doing reference all home on start-up, when the Z  switch trips, the reset button lights up and gives a Limit Switch Triggered message.  My student wondered if it had to do with the velocity being reduced, but changing it to different rates has not effected the problem.

Any thoughts on that?

Thanks for the help.
