Limit Switch not working at all

First off thank you for everyone who’s gotten this far. I’ve installed limit switches on both Y- Y+, X- X+, and Z+ first I wired them each to there own positive negative pins on cnc shield (NOTHING) I put capacitors in line (NOTHING) I set the 5$. To 1 (NOTHING) I’ve tried wiring in series (NOTHING) Tried homing all it does is throw alarms using shielded cables with 47uf capacitors nothing will trip the switches I’m about to give up on limit switches but really looking for some help please I’ve included a picture of the limits switches I purchased

 

O and I’ve tried AO and AC nothing is working

 

My CnC sheild says Protoneer V 3.0 on it But guessing that can be faked also

 

Well I feel stupid, this morning was looking at the wiring for the limit switches and notice used the incorrect capacitors they were not letting the signal go though took them out re-hooked up checked the continuity everything was working correctly, threw the switch in OpenBuilds alarm came on but was able to reset the trigger in OB this time and it stayed off, going to give it a try and see if I can trigger them while it’s in motion
I’ll let ya know what happens

 

Well they kind of work. I can trigger a switch. Reset the system trigger another, so it seams to be working. But when I activate the soft limits it triggers in the middle of the run. Nowhere near the switches. But only which the soft limits activate, any ideas

 

Sad to say no,I've read so much on OB form it’s quite overwhelming sometimes. But I’m finding building was much easier then programming for me at least, this will be my next step getting to axis’s programmed. Thanks for information

 

Probably did hook them up incorrectly, Im as green as green gets Building it was one thing, getting it programed correctly will be another, and its been frustrating to say the least. But you all ahve giving great pointers and suggestions, Getting me pointed in the right direction,

Thank you all

 

I wish I could but it spendy and I have all these drivers DN556 I wish I would have found this site before I bought everything but during my research OpenBuils never came up until I did a forums request on CNC router issue in google search (maybe someday) Thank you

 

Another question Could I use my Nemia 23 stepper motors I already have if I build a machine from like V-Slots If a can utilize some of the gear I already purchased maybe I can build a much stable working system in the near future

 

I feel really stupid when I type questions so bare with me please, most of the information I've gathered from building this CNC was a copy and paste you might say. But these are the motors I have

Nema 23 CNC Stepper Motor 3A 178.5oz.in 1.2Nm 57HS56 CNC Stepping Motor DIY CNC Milling Engraving Machine (178.5oz.in-1.2Nm).

 

The One is from my duel Y drives, and single X drives. The other is my Z drive as you can see

 

Thank you for all your input I’ll most likely rebuild it in sed V-Slot rails I’ll just have to buy parts as I can then go from there. (wife will kill me ) Thank you again but I’ll have to keep messing with my DYI for now

 

Peter I tried asking you a question in conversation but it wouldn't let me so Ill ask here

Looking at the V-Slot Linear rails there very log for my application. First off the main reason I built a CNC router id to eventually make guitar body's some day after I get better at it. Right now I do it th by hand. And a year ago a put a router threw my wrist, was bad. But anyways back to my question can the V & C slot rails be cut to size

 

O that’s nice very cool thanks

 

Have a question when Im setting up my $130, $131, $132 I watched a video on Youtube on how to do it seams easy enough. But my question is before you start do you want to zero your axes before starting that way when you jog the machine from the right rear corner to the front L corner and get your - setting numbers would that be correct? Not sure it makes sense

Thank you

 

Ok I just purchased the black box just can’t seam to get those DM556 drivers to work correctly no matter what I do. Couldn’t pass up the Black Friday coupon. Just hope it’s worth it

 

No I purchased the black box because I was having nothing but issues with the DM556 drivers getting them fined tuned, and it just showed up today, can’t wait till Friday to hook it up
