Hey John I need to also design a similar circuit to control my oiler on my cnc. In my case the oiler needs to be turned on every 3 mins or so I think for 20 seconds.
Just wondering if you can expand on that example. I am just coming to grips with classic ladder now
The first rung is a self reseting timer. A TP timer the output is on until the count is reached. As soon s the count is reached the first timer resets to 0 and starts to count down again. Might not be the best way but it's what I came up with 2017.
The second rung when the output bit goes from off to on that timer starts and the output from that goes to your pump.
For some reason I am not getting notified about any replies hence the slow reply sorry.
I have been looking at the example classic ladder sim and running it and the ladder part all makes sense and is perfect for what I want. I just want to turn on a relay to power the lube pump on for 15 secs every 15 mins. and so you example is perfect.
What I am struggling with is how to actually connect the Hal pins to classic ladder. I have been reading up on HAL and watching videos especially Sam ("green machine videos") and ("estop video"). I think I understand those videos and can use Halcmd ok now. but I am still at a bit of a loss on how to connect the hal to classic ladder. It must be pretty simple lol. But the manual doesn't say anything in the examples that I could see. I think it must be so simple that they just seem to assume that people will have no trouble.
I am going to do some testing now and hopefully I work it out if so I will post back here.
have you ever retrofitted a vmc toolchanger? I am looking for examples to get me started
I think i have started down the path. I can connect hal pins to classic ladder now and can change classic ladder stuff which was my first hold up. But now I have to decide how my logic will work
