Now, use the quadratic formula to solve the quadratic part, and you’ll see that the velocity equals zero (in other words, is stopped) when t = –1.5, 0.6339745962, 2.366025404. Use synthetic division to ensure that this is true and to factor the equation. (c) If you graph the velocity function on your calculator, you see that it appears to pass through x = –1.5. (b) Simply plug into the velocity equation to get: v(1) = –5 in/sec, v(2) = –7 in/sec, v(4) = 121 in/sec. (a) The velocity is the derivative of position, so the velocity is v( t) = 4 t 3 – 6 t 2 – 12 t + 9. (g) When is the speed of the particle constant? Solution: (f) Calculate the acceleration of the particle after 4 seconds. (e) Calculate total distance traveled by the particle (i.e., forwards and backwards) after t = 5 seconds. (d) When is the particle moving in the forward (positive) direction? (b) Compute the particle’s velocity at t = 1, 2, and 4 seconds. I'm using A4988 drivers.(a) Calculate the velocity of the particle at time t. On Step pin, it's just like Dir only it's dimmer this time. led is pretty much completely lit (no blinking) on Dir pin. This time, Enb pin doesn't turn on the led, but Dir and Step do.

So I tried moving the axis a bit then probing again. At this point only Enb pin turns on the led. I turned printer on, connected Repetier Host, tried Enb, Dir and Step pins.

What sort of stepper drivers are you using? It can be quite amusing if you have any musical tendencies - I often hear melodies as my printer does it's thing Yes, whining stepper motors tends to be normal. You want to be able to concentrate on the + side of the probe and not worry about the other end. You can connect to it anywhere that's convenient, but it's often easiest if there's a spare connector at the power supply to wire the probe in there so you don't have to try and hold two connections in place by hand. I just meant the 0V or sometimes marked as -V side of the supply. The probe is ready, I just couldn't figure out what you meant. I'm sorry but I'm not sure what you're referring to when you say "Supply 0"? I know where the enb, dir. You don't want to short anything out either. It may be tricky to find a good place to connect the probe to to test this, it's not something I've tried. I don't know which will be positive and which negative, so you'd either have to try it both ways or solder a second led back to back with the first one so that one or the other always lights up.īe careful not to accidentally disconnect the motor, the stepper drivers can be damaged if disconnected while powered up.
#ESTLCAM Z MOVEMENT PROBLEM DRIVER#
To check for output from the stepper driver you would connect the probe across each of the motor output pairs. What voltage power supply are you using? You can probably use the same 1k resistor for a 12v setup, the led will just be brighter. You can compare with the x or y axis to check what it looks like when things are working, but I would expect the enable pin to be on all the time, the dir pin may or may not be on depending on which way the motor turns and the step pin should flash (but probably too fast to see, may just look dimmer than solid on) when moving. Then carefully hold the pin to the enable, dir and step pins in turn and see if there are signs of life. Connect the negative side of the probe to the supply 0 and solder some sort of mostly insulated probe pin to the positive side of the LED (a piece of solid core wire would do).

#ESTLCAM Z MOVEMENT PROBLEM SERIES#
How would I do it with a an LED?įor checking voltage output from an IO pin you could just use a LED in series with a 1k resistor - that would draw about 4mA and should be visible, and the IO pins should supply that easily. They're pricey!Īnd I don't think my multimeter has frequency or duty cycle modes. I don't have access to an Oscilloscope unfortunately.

I'll have to wait a few seconds for the non-existent Z movement (as if it's actually moving when it's not) to be finished and then the next Z movement commands work.Įdited 1 time(s). The endstops are working correctly, they show low when endstops are not triggered and high when they are.Īlso, if and whenever I press "Emergency Stop" button to stop everything and then try to move the Z axis, it won't move. And the driver currents are adjusted correctly. This results in the everything getting printed on first layer.
#ESTLCAM Z MOVEMENT PROBLEM MANUAL#
It DOES however move during homing and in manual control. The problem is the Z axis does not move up after the printing starts. I'm new to 3D printing and I've recently finished building my printer ( Cherry 3D printer) and have been trying to fix it's problems, this one I could not figure out, so maybe you guys can help me out!
