Re: [Emc-users] Simple, adjustable timer
Hi Viesturs. Finally I can send to you the HAL component for the blink function as I explained before. This is my first component I wrote so for sure somebody else can do it better than I did . Anyway let me know if this component is useful for your needs (for me it is) . ;-) . You have to add one or more instances of the component to the servo thread (1ms).

Otherwise they are iffy. Another idea; Put a reflector in the grit tank on an angle so the grit falls off the reflector. Then use a standard light sensor aimed at the reflector in the tank. When it is covered with grit - the reflector is blocked. When the sand falls off the reflector the sensor sees the reflector and you can add more sand. I had to do something similar to measure the height of a dirt pile (a small one) for a farm machine. An ultrasonic didn't work for that application. I'd run the input to a unused Mesa 24 volt input and put some logic into Classic Ladder for a couple of timers to condition the input with time on and time off delays so you don't short cycle the grit loader. Or just tie it in via hal if no timers are required. Dave On 3/21/2015 12:24 PM, jrmitchellj . wrote: How about an ultrasonic range finder to watch how full the small hopper is? Ray --J.

Re: [Emc-users] Simple, adjustable timer
There are no sensors or anything I could use A timer will be at best cumbersome, and it is a dumb control in that it doesn't have any information about the desired result. If activated when the bin is almost full, it'll overfill the small tank. I prefer the data driven approach. I'd add a sensor. A capacitive prox sensor seems ideal for this application. https://duckduckgo.com/?q=capacitive+prox+powder On 03/21/2015 10:22 AM, Viesturs Lācis wrote: Hello!

There are no sensors or anything I could use, so currently my only idea is to turn it on and off on timely basis. So the question is - what HAL modules could I use? The thing is that user has to be able to adjust on and off periods from a vcp panel.

Re: [Emc-users] Simple, adjustable timer
Ultrasonics work ok if the surface is relatively flat you are aiming at (like liquid level). Otherwise they are iffy. Another idea; Put a reflector in the grit tank on an angle so the grit falls off the reflector. Then use a standard light sensor aimed at the reflector in the tank. When it is covered with grit - the reflector is blocked. When the sand falls off the reflector the sensor sees the reflector and you can add more sand. I had to do something similar to measure the height of a dirt pile (a small one) for a farm machine. An ultrasonic didn't work for that application. I'd run the input to a unused Mesa 24 volt input and put some logic into Classic Ladder for a couple of timers to condition the input with time on and time off delays so you don't short cycle the grit loader. Or just tie it in via hal if no timers are required. Dave On 3/21/2015 12:24 PM, jrmitchellj . wrote: How about an ultrasonic range finder to watch how full the small hopper is? Ray --J.

There are no sensors or anything I could use, so currently my only idea is to turn it on and off on timely basis. There are long-range optical sensors that are used for this exact purpose. When the hopper is full, it blocks the light and shuts off the filling. These either have one unit and need a mirror on the far side, or they have two units, one sends the beam, the other senses it. We even have stuff like this on our electric garage doors to stop them when someone is under the door, so it is not real high-tech stuff. But, you can get modular electronic timers for general industrial control purposes. Some have dials, others have screwdriver slot adjustments or switches to set the time.

Re: [Emc-users] Simple, adjustable timer
I'd go the Classic Ladder route and program a 1 second timer and use that to increment a counter when the timing conditions exist. Then do a comparison to a preset value for the number of seconds of preset time. You could use a spinbox to set the value of the preset for the comparison. I know that would work. http://www.linuxcnc.org/docs/html/ladder/ladder_examples_fr.html Dave On 3/21/2015 2:45 PM, Viesturs Lācis wrote: 2015-03-21 21:11 GMT+02:00 Dave Cole linuxcncro...@gmail.com: I'd run the input to a unused Mesa 24 volt input and put some logic into Classic Ladder for a couple of timers to condition the input with time on and time off delays so you don't short cycle the grit loader.
