:'(
Hi all,
I was thrilled to have the little Sherline Lathe up and running and I machined a miniature baseball bat.
I moved the setup from home to school but when I went to demonstrate it to one of the other teachers I lost the X axis. I have lots of spare parts so I replaced the driver box, stepper motor and all cables, thinking that something had been pulled apart in the move. No luck, and I can not identify any changes in the configuration screens
Any help would be greatly appreciated.
I have attached the xml file in case someone can see the problem there.
Thanks again,
Norm

Swap the axis, ie; Z for X and see if you get movement since at least that may give you an indication of what is wrong.

Thanks Rich,
I will try that right now.
Norm

Tried that and I gained the X axis and lost the Z axis.
Thanks, at least I can rule out hardware now.
Thanks again,

Post your xml file that you are using.

Hopefully this is not the third repeat,
Just having a few problems a t this point.
Here is the xml.
Sorry,

Norm, you don't have a port number assigned to the step and direction pins in Motor Outputs and you only have the y enabled. You will want to assign port and pin numbers to the x and z and make sure they are enabled. You may also need to assign a port and pin to the estop input. I would assign it to port 1 pin 11. You can change the active state for e stop to over ride it but I do not suggest that, your estop should be priority 1.

Thanks Brett,
Currently, I am using the toogle switch on the Sherline driver box for my ESTOP as suggested by Sherline but only for testing it out. I will set up an ESTOP shortly and most likely run it through a second printer port. Thanks for the suggestion it is a very high priority to me also.
I will look again at motor outputs but it appears as that X and Z are enabled and set up on port 1 using 5 & 4 for X and 7&6 for Z. I will go back through it tomorrow. I am hoping I didn't send you the old xml file.
Thanks again,
Norm

OK Norm, you may well have posted an old XML as the only motor enabled is Y. Also, I didn't see any other inputs assigned. In any case, I would set the estop pin to pin 11 port 1 for now at least. The estop must have a port and pin assigned to it, this is not optional. Weather or not you have it physically wired is up to you but I strongly suggest that you do.

Sorry again for sending the old file last time. This is the latest version. I will make the ESTOP a priority.
Thanks again for the continued support.

Hey Norm, that xml looks a lot better. It works as it should it here. When you say you lost the x axis, I'm assuming the x axis does not move at all? Does the DRO for the x axis change?
Brett
-
HI Brett,
The Tool does not move, however the DRO does show the x-axis moving.
Thanks again,
Norm

Swap pin assignment in Mach for X and Z and see if the Z stops working and X starts (not physical X and Z but Machs X and Z)

Hi Hood,
I swapped pin assignments. when I jog the x axis Z moves, when I jog the z axis nothing moves. The DRO responds in both Axis.
Any advice will be greatly appreciated.
Thanks again,
Norm

Ok sounds like a problem with the parallel port I would say.

Thanks Hood,
I will try hooking it up to a different computer.
Thanks again,
