Lost.....very lost

[gemmi8]

Hello to everyone. So we are completely new to this my son wanted a machine to use at home as he uses one at school and is familiar with the operating system once we get it up and running and we were able to secure one thanks to a wonderful contribution and we've got the assembly 95% complete. However I did fry the Uno board and had to go get a replacement not a big deal we went got a replacement loaded grbl into it loaded everything into it that works just fine however when I plug in the power nothing works the stepper drives only two of them would register so I started troubleshooting by simply taking things off of the CNC Shield because when everything was plugged into the CNC Shield the computer woulnt unconnect the Uno board. So did troubleshoot we started taking things off one at a time and it would only register that it was plugged in if there was only one drive in there. So at this point did we fry our CNC Shield board as well? Because even with one in and the computer recognizing it would try to jog that access to machine will not even turn on it doesn't make a noise it doesn't make a sound I'm assuming the machine would make some kind of sound when we plugged into power and it powered up in the code sender. It shows the machine as active and Jog but the machine does not say no noise nothing. We are completely lost trying to figure this out if anyone could help we would greatly appreciate it.

Hey Gemmi.

I see we just also sent you an email about this. That will clear things up some. The stepper drivers would have likely also been fried and are what is preventing the uno board from booting whenever its all plugged in together.

We can provide you some low cost replacements on these. Hit up back on email and we'll sort it out.

Thanks! I ordered a set that should arrive on Wednesday from Amazon. Fingers crossed my son and I get it right this time.

Also am curious to the fact when installing the Homing switch for the Z axle the bolts and the T nut will not stay secure it continue to slide in the track. Am I wrong in that it should stay secure or should it slide

It should be tight. It needs to be secure to switch on as the Z axis moves up to hit the rocker arm of the switch.

I figured it should be tight. I can't get it any tighter so not sure if I need a new T nuts and screw or try another way to get it to stay put.

It doesn't look like the z axis limit switch mounts on the rail. I don't have an M3 just going by the manual.

manual says:

(F). You’ll need one limit switch, two M3x20 screws, two M3
split-lock washers, two M3 flat washers, and two M3 nuts.
Install the switch in the orientation shown in the picture. Slide
an M3 flat washer onto the M3x20 screw, then slide the bolt
through hole (F) and through the homing switch bolt hole.
Secure it with an M3 split-lock washer and M3 nut. Do this
with both holes. Snug it up enough to flatten the split-lock
washers, but DO NOT OVERTIGHTEN OR YOU WILL DESTROY
THE SWITCH.

I'm guessing you really mean the X or Y-axis homing switches because those are the ones attached to rails.  Make sure you added an M5 washer between the M5x12 screw otherwise you won't be able to tighten it down all the way.  The switch bracket should be tight.  If that still doesn't work, make sure the screw is not longer than 12mm.

Here's a picture of the y-axis switch from page 23 of the M3 assembly manual for reference.  Page 27 shows the same thing for the x-axis.
