almost Newbie lost x axis movement
« on: February 13, 2013, 04:26:19 PM »
 :'(
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.

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

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.
