Joypad quits working at random?

Hey guys,

I have version 2.5.1 and ever since moving to the 2.5 train I have had intermittent and unpredictable difficulty with the joypad going dead while the machine is in operation. It generally seems to happen to me when I put the controller down for a while and return. Sometimes when I do that I am no longer able to use the joypad. Looking at HAL it seems to have just decided the joypad doesn't exist any more. Restarting AXIS will get me the joypad back but that means rehoming the machine and I don't yet have home switches so that will guarantee inaccurate parts.

Is this something that anyone else has seen? It's really frustrating and it never happened in 2.4 but I had to upgrade to make certain parts of my control panel that depend on subroutines work correctly.

I use a joypad with 2.5 and have never had any issues with it.

I suspect a bad USB port or cable or plug. If I unplug my joypad the GUI still works but Input goes away.

I am using 2.4 and 2.5 and have not had a problem.
I did have a usb memory stick that did that but it turned out to be a bad memory stick.
Don't forget if you are using the simple remote pendant the jogs only work in manual mode.

Well that's good and bad news. Good news is that it doesn't seem to be an systemic problem so it ought to work fine. Bad news is that I have no idea why it isn't working and so far logs have not shown much to go on. Yeah I do know that the jogs don't work in MDI so the joystick push-down switches to manual when I need to jog. Once this issue occurs the joypad is gone from HAL so nothing on it works at all but it's not gone from the PC. It's still present in the devices. Could be some brief connection issue though I guess where it gets unloaded from HAL but is there by the time I go look at the devices.

Are you using an extension cable on the joypad?

It seems to me that one machine I worked on had a problem with a 6' extension, but it is now plugged into a usb hub that has a separate power supply and all is well.

Yes, mine does it. It has done it in 2.3, 2.4 and now 2.5. I have always assumed it is a problem with my Joypad rather than LinuxCNC, as the "Mode" button with the LED also stops working at the same time.

I think plugging and unplugging helps sometimes but not always.
