PLEASE HALP WITH POWER SUPLY, LIMIT SWITCHWS AND E-STOP

Hello
I have uploaded an image of the masso wiring diagram that I have completed.
I believe the drivers to the masso are correct, if I am wrong please correct me...I am not an a pro.
also I am asking how I should connect the e-stop to the power supply, and the limit switches connections on the Masso? I an very confused... sorry.

could you draw me out something that would show me the correct way like I drew for you. I am a visual person.
If you could help me I would be very appreciative.. Thank you.

Hi Me GOK again.
based upon the drawing you have in documentation. it shows the power supply going to the e-stop and then on to pin number 2 e-stop. i just don't understand what i should do with the other not used power input pin on the masso. I also don't understand exactly how the limit switch wire to the power input is to be connected to the e-stop...sorry about my ignorance.

I only have the one e-stop at the moment however I will purchase one from you when I have a little more cash.

As it is wired up now, the e-stop does cut the power to the masso, But I think this not the complete or correct method.
this is why I asked for a drawing like mine. I know it is a pain. I am truly electronically uneducated.
the attached image is the actual e-stop I am using "lay7(PBCY090)lay37 e-stop"

you have been very supportive in all my questions. thank you so much!

when i said that

"I only have the one e-stop at the moment however I will purchase one from you when I have a little more cash."

I meant to say that I would buy a pendent from you not a e-stop

  1. The power to the controller is fed from the power connector on the right side of the controller.
  2. Connecting +ve of the power supply via the estop button is just used to give the estop signal and its not powering the controller.

Thank for getting back to me so quickly friend :)

So The way i have the e-stop connected is correct? I should connect another wire "+ve" from the power supply via the e-stop button as in the new image I have attached?

I am not sure if I have the limit switches and the stepper drivers wired correctly. How should I reconnect them if they are not correct?

thank you very much for your support friend.
much appreciated.

Some small issues with the wiring, please see below:
  1. You need to connect the +ve from the power supply directly to MASSO+ve connector for power input, you have it through the estop and that is wrong.
  2. Next wire the +ve from the power supply through the estop to the estop connector Pin: 2
  3. Homing/limit switch wiring is ok.
  4. Motor drive wiring is perfect.

I wire a lot of controllers
what I would suggest
all limit switches use NC take a pos wire from the power supply connect to a fuse or breaker low amps like 1amp
then wire that power to each limit switch. connect each limit switch to its proper input of your choice set it up in the controller.
do the same for your estop use NC. estop does not wire to the limit switches.
add more estop put them in series .
the reason for NC is if you have a problem it will show right away .
and the fuse powering the switches if a wire shorts the fuse will protect the output of the supply.
I use 24 volts for every thing. I install a buss off the power supply protected buy a fuse or breaker
that buss is used to power the limit switches and estop and anything else needing input power.
I run a single wire to the controller to the supply for controller power.
if it is plasma I use a separate supply for the THC to insure torch voltage no getting to the controller supply.
I use the small din rail power supply I like the mean well MDR 100-24 its 4 amp its works well for controller power and it has voltage adjustment
hope this helps

Thank you jcoldon :)
it makes sense.
I will get another power supply and give it a try. I will keep you updated.

Hi jcoldon
thanks for helping me out.
I just put together a sketch of what I believe you were saying minus the blade buss'. Is my new attachment what You were speaking to?

Thanks again.

yes that is correct just protect the voltage feed to the axis limit switches with a fuse or breaker. same for estop incase a shorted wire.
any time you run wires out of the controller protect with a fuse or breaker in case of short . you should use all shielded wire. ground the shield at the controller end only. to a ground. I use a negative ground buss in the controller ground every thing to it even the power supply neg
that way if I need a ground I just grab it off the buss
you should use shielded wire to your stepper motors
also use the same length wire if you have 2 motors on 1 axis this ensures the voltage drop will be the same for each motor
as for voltage that depends on what stepper motors you use and what driver also . most of the time 48 volts is a good stepper motor voltage
make shure you use a driver that can handle the same amperage as your motor and a power supply the can handle the total motor amperage

Hi jcoldon
thanks,
yes the wires are shielded, I still need a buss. i am ordering it tonight.
the motors and drivers are matched(although from China... longs)
you have been a wealth of good information friend!
I owe you!

sincerely,

Hello sir,
I have attached a image of How I have wired up the Masso controller to the limit switches, the fan and the E-stop.
everything turns on, but I and seeing two blinking alerts,(1. e-stop release button and 2. door is open) I am very confused...
I thought that I had the connections were correct?. do you know what I am doing wrong. please help me! also I cannot get the motors to jog

also, I pressed and reset the e-stop many times to see if this would help with no results. the e-stop did nothing.

thanks again with any help you can give me friends.
I truly do not know what to do.

please show me where I went wrong?

Thank you so much friends?

Thank you so much

  1. So when you press or release the estop, you don't see anything different on the screen?
  2. What voltage do you see on estop Pin:2 when you press or release the button.

I have attached a jpeg of the screen showing two lights blinking on startup.

also a screen focusing on the current going into pin 2 continuity is good coming from the fuse box thrue e-stop to the pin and breaks when I push the e-stop.

I tested for current and voltage which can be either 12v or 24v if you like. it is a separate power supply to avoid any noise effecting the controller. it works to power the controller. and it travels thru the e-stop onto pin 2, unless e-stop is depressed. I tested to see if there was continuity out of the e-stop after t it was depressed , and there was not so it must reach pin 2 when e-stop is closed.

also a jpeg of the screen after hitting the e-stop showing the two same lights blinking... no change.

also I have attached a image of my control box. I doubt it will help but just in case.

any help would be great!

the power into from the fuse bus into the pin 2 are at less than 24v



thanks

George

Thanks for getting back to me.

so I should press and reset before the masso logo comes up?

and will this be something I will have to do going forward?
