Bigtreetech Scylla V1 firmware installation.

Trigger the endstop manually and while holding the endstop activated, type M119 in the console. You should see which endstop is activated.

Returns  when I put m119.  But I perhaps have not put something in config.g that is needed, I checked limits, the information is there..

Check your endstop settings in limit.g if wired and configured correctly it should show triggered when depressing the microswitch and entering m119 in console

This is the code I put for it at the start (was recommended), is there somewhere that I need to enable the ports?  I do not get the message you say I should with M119.

You haven't answered my previous question about whether the microswitches are wired normally closed. Use a multimeter to verify.

Wire the endstops normally closed (Com/NC) run the two wires to Negative and Signal on the Scylla board.

So I checked the actual order of when I bought them, they are classified as normally open from the manufacturer, not sure how I would re-wire them to work.  Sorry for all the questions.

Sorry about that.  Crap, just realized normally open, I suppose I will need to buy new endstops?

Microswitches usually have a common normally open and normally closed connection. Most likely, the open slot on the three-pin connector is the normally closed. Meter that common and the port connection to see if it closed.

Don't be sorry that what we're here for is to help and guide!

[real1st]

So this is the endstop, its G, NO, NC.

 

So I have wired gnd to gnd, and signal to NC.

 

I dont have my meter here, im at my home office.

[PFarm]

Yes, that's correct. The reason for wiring them normally closed is that the Scylla monitors that an endstop is present.

Still the same thing on interface, and no light on the board (I was reading it should light up?)

[PFarm]

Did you set the jumper for the Vlim? Although we aren't connecting any voltage cables, a jumper is needed for the endstops to work.

[real1st]

I did not!  Which one am I supposed to set?  the 5v?

Anyone will work, I set mine to 5V.

[real1st]

I connected it to the 5v.. now when I push the endstop the light comes on!

[PFarm]

Cool, now verify the endstops as mentioned previously.

Okay, so I when I press the endstop down, the message changes to this:

 

before it said x: at min stop like this

[PFarm]

That's what you want to see; verify the other two. Sorry couldn't remember what the message was when you used M119 to check. I'm re-wiring my Casa, so I couldn't check on my mill.

So I understand, with my other experiences with printers, we use the limit switch so when we home, it will hit the endstop but if its NC then how does that work?  

When I home shouldnt it be stopping when it hits it?  seems like for the way its setup it has to be pushed down for homing to happen.  

[PFarm]

It's different from 3d printer endstops. It will hit the endstop and reverse off the switch by 5mm.

Okay, so when I do NOT hold down the x endstop and press HOME X, it moves like 1 second.  Then it stops.  But if I HOLD DOWN the x endstop, it keeps going until I release it.. Seems odd to me.

[PFarm]

As I mentioned, the axis will hit the endstop, then reverse 5mm.

Yes, I get that, that it goes back 5mm.. I get that completely.

 

What I am confused about is.. if I DONT hold down the endstop, it will not sping the motor back the 200mm (for example if I was 200m to the right) to the 0 position where the endstop is.. so when its installed the endstop is not being pushed.. thats why I am confused how that works.

Try putting ! before the P"name" Example !P"PD_11"
