    X axis problem

    I think what I'm going to do is build a test model using one on-off-on switch. The 2nd on will reverse the polarity of the dc motor thereby reversing the direction of the carriage. Simple and easy. If I have a problem with reverse-direction smoothness (which I don't think I will because of the...

    X axis problem

    I'm looking for the simplest way to build a gantry that travels back and forth on the X axis only without it being hooked up to a computer. It will be belt driven and controlled by an 18v dc drill motor. I was thinking about using an "on-off-on" switch at each end of the gantry slide to...

    Question: Off Delay Timer

    I was thinking.... I could run an off delay timer through a pot to get the slow speed for 5 seconds. Then install an "on delay timer" that turns on after a 5 second delay, runs wide open for 5 seconds then turns off. That might work. Now all I have to do is figure out where to get the...

    Question: Off Delay Timer

    Hey Merlin, The 3 states could be... 1) Motor A & B on (motor B running at a slow speed... 60 rpm's or so for 5 seconds) 2) Motor A turns off and Motor B turns off 3) Motor B turns on again at a higher rpm and runs for 5 seconds then shuts off Here's an idea I had...

    Question: Off Delay Timer

    constant load? I don't understand your question. If you're asking "are the motor's under constant load when they are turned on" then the answer would be, "yes." I was thinking on the speed control.... cordless drill motors have 2 speeds (at least the 14.4v dewalt drill I have does). So...

    Question: Off Delay Timer

    Hello everyone, I know nothing when it comes to electronics, please be patient with me. I'm looking for an adjustable off delay timer that can delay multiple (2 or 3) small dc motors (cordless drill motors). Here is what I want to do.... Motor A & B - both motors turn on (run) when...
