    Does ‘run as administrator’ get you any different result?
  2. Controlling Cylinder Stroke Length

    I’ve done some minor programming projects (mostly conveyor systems). And wanted to tackle something new, so all the information/help everyone is providing is greatly appreciated!
  3. Controlling Cylinder Stroke Length

    @kaiser_will thanks for the information; I’d prefer to go with pneumatic or electric controlled cylinder. Must press within a equal to or less than 0.5mm threshold, and will have various settings for stroke length (lets just say 3). So a selector switch to determine three various stroke length set points. Time allowance would not be hateful, whenever the operator is clear (at the proper operating station) to hit the cycle button the cylinder extends to x length and retracts to ‘home position’/retracts. The servo cylinders seem ideal to allow better control from the information you provided, thanks.  
  4. Controlling Cylinder Stroke Length

    @pcmccartney1 thanks for the link, very interesting and going to dive deeper into researching on those cylinders.
  5. Controlling Cylinder Stroke Length

    I do not think the rodless cylinder would provide enough force at the end for this application? I could be wrong though, would have to investigate further.
  6. Controlling Cylinder Stroke Length

    @pop29684 1. I am open to options, would prefer to stay away from hydraulic though? It is being used in a food application and I feel like hydraulic leaks in the area would be bad.. This is my first project of this nature so really just trying to bounce ideas out there and get input from others with more knowledge than me, thanks
  7. Hello - I've recently started my adventure into PLC programming and I've found this site to be very helpful. I took on a project that requires control of a cylinder - the short and skinny is that the cylinder will have to provide position feedback and stroke to various set lengths determined by position of a selector switch. So - If position 1 is selected, the cylinder will stroke 20"inches. If Position 2 is selected, cylinder will stroke to 25"inches - so on and so on.   My questions is how to best go about this process. I may be having a brain-block and not viewing this clearly, but something is not clicking for me and wanted some advice. Planned on using Allen-Bradley's Micro850 PLC (had one on the shelf, and CCW software is free so why not). Thanks
