Thank you !!!
I don’t have it in front of me so all I can say is it’s very strange to have “NO” and “NO”.
It should look like this with one “NC” and one “NO” and one “C”. I didn’t have one handy to take my own picture but after looking at a bunch of pictures online it appears that normally closed (NC) is always opposite the “C” position and normally open (NO) is the middle connection.
So yes you would solder the two outside ones and leave the middle tab unconnected. This is for normally closed configuration.

The lettering is so small that it could perfectly be NC NO and C…and me being a complete novice on the electronics scene does not help at all. Thanks for your help and time.

The pole in the center you don’t use. It’s NC normally. It depends on the switch. The switches in the V1 kits are that way.
That’s what I’ve done.

@jeffeb3 hello, have everything wired up…but SKR board has power in and motors…do I have to feed both with power?
Thanks,
I have tft on and seems to be power but for some reason I have this message on the screen…no printer attached, and moving doesn’t work!!!
Heeeellllppp, please !!!
Yes. The way you have it wired with motor power in the second pic is right. You need to have the baud rate set to 250k. I see you’re using espanol, did you compile that firmware yourself? The one in V1’s github is needed to work with this firmware.
Hi @jeffeb3 , I didn’t compile anything I haven’t changed the language actually…it’s in English and some bits in spanish, haven’t got a clue on how to do it 
…I flashed it with the firmware.bin you told me to…but touch screen won’t let me move any axis manually, only when I get into Marlin mode…with the knob I can move axis around…I’m sure I’ve got something wrong as I can’t get the Y axis to touch the endstops…and on the main screen as you turn the board on it shows axis X and Y 0? and Z=200…I need to understand which way they should move as I tried to print the crown and started going the wrong way…so stopped it and thought I’d better ask the experts… 
What’s the Baud rate 250k ??? And is there anything else I need to download from github? I got this https://github.com/V1EngineeringInc/MarlinBuilder/releases/download/502/V1CNC_SkrPro_DualLR_2209-2.0.6-src.zip
If it’s of help I can record a short video on the start up of the board and then you might see it clearer…
Thanks for your patience and help…
And should this be set as per pic and travels as shown???
The y is going backwards compared to mine. If you look at how the lcd is mounted in the pics, your head is facing up the table,
Cheers!
So I understand I must change the connectors backwards…btw do you know why is it not going to the end of the table and touching the endstop switches?
Could it be something to do with the firmware not being properly flashed on the SKR board?
I tried do the crown but went off the wrong direction…I have the gcode to start on the left side of the table and then move to the crown which is set at the right of the start point…but instead it went to the left…not too sure if I have the right settings on the board and I don’t know how to check it.
Thanks,
Here’s my Gcode if it helps…

I was just going by your diagram of the directions and assuming the position of the viewer as facing the bottom edge, if you jog the machine is that accurate? For me, facing the machine from the rightmost long end with the electronics to my left, I jog x in the positive direction and it goes right, jog positive in the y direction and it goes away from me. It seems to match up with what I do in CAD, and I don’t get mirroring, so I assume it’s correct enough. 
(reversing x and y is an option too, I did that for a while)
If you are homing you are using the min end stops, the max end stops cut the power when hit. At least for me. I don’t use them myself on my low rider as knowing where the corner of the work piece is more meaningful.
To check it just jog the machine using your gcode sender software, or if you have an lcd with a file on an sdcard, go to motion, y axis for example, pick 10 mm and turn the knob or use the touch screen, whatever you have set up. I didn’t read the whole thread, just saw the diagram and it seemed different to me.
You are going a bit faster than me on Z, if it works for you, great, but I stick below 300, it screams less.
My files have this at the beginning:
G90
G92 X0 Y0 Z0 ; the tip of your bit is 0, 0, 0
G21 ; numbers that follow are in mm, G20 if inches
You can set that up is estlcam.
You are starting at the bottom left on my machine, I’ll skip the rest, it’s all within the 100mm first square for the first few etching sections and at the end.
You need to flash the tft too. There are files to put on an sd card and put into the tft and reset it. It will tell you it is updating and then reboot and you can remove the sd card.
More details:
https://docs.v1engineering.com/electronics/skrpro/#tft-files
Before trying your own gcode, make some movements on your own and make sure positive X goes right, positive Y goes away and positive Z goes up. Then male sure a 10mm movement in each direction is actually 10mm.
Then, use the gcode test crown. That will check out the machine oretty much completely. After that, post a pic of the crown here and try to follow the estlcam basics and make your own.
Hi again @jeffeb3 (your nightmare is back online ) I downloaded files as shown on the picture attached, saw some updating as screen started up and then asked for re-calibration, but got to red dot 3 and then a black dot in the middle of the screen, after that it kept asking for re-calibration and a calibration error, icons have changed but the touch screen is not working anymore and can’t change to knob control on Marlin.
Any ideas what have I done wrong? I’m sure it’s my fault…once again…jeeezzzz
Remember I’m using the Bigtreetech 3.5 TFT V3.0…it’s not the E3…I don’t know if this might be causing trouble !!!
Thanks,
@ByronM I think you’re right there…I’m now going to change connectors direction…so the Y axis travels are done from endstops, at top of the table where I have my screen, to the other end being that a negative move…and positive when homing back towards the screen.
@jeffeb3 After reading the guide I see dual endstops are for X and Y axis…is that correct? I’m asking because it makes sense to have endstops on the Y axis to make sure it’s square, but why on the X and not on the Z axis??? Probably me missing something here…
Thanks,
It’s all relative.
Z, no idea, a few people home upward.
Cheers!
Hmm. Not sure about that one. You may have to download the source code from that repo, change the platform.ini file to choose the target for your TFT and compile it using platformio. I am surprised it let you flash it, but the two probably aren’t compatible, IDK.
The MPCNC has 2X and 2Y. It is really where we have a lot of experience with dual endstops. The Low Rider is usually huge, and once the steppers are on, they move in lock step, so it isn’t as hard to get square. I am (slowly) working on a LR setup with Dual Z, and it homes up and probes down. But I don’t have that quite ready yet.
@jeffeb3 So no dual endstops on the firmware I flashed into the SKR board then…and regarding the repo, platform.ini etc…it sounds from outer space to me…the thing is before I did anything to the screen I could move axis under Marlin using the knob but now I’m stuck here with the screen blocked.
Any chance you can help me on this one? I know you have your own life but I haven’t got a clue on where to start to be honest…and I’m so close to have it running…I’ll contribute $ if needed…but I can’t go through a full learning process at the moment !!!
@ByronM Re Z axis, I think it could make sense to home upward in order to safe your machine while you have a bit on it…but I’ve never used a CNC so I’ll have to learn how things work, and do my own in time…but for now I want to stick to standards that work.
Thanks everyone for your help, honestly !!!

Have you tried going back to the original firmware for the screen.https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/tree/master/Copy%20to%20SD%20Card%20root%20directory%20to%20update%20-%20Unified%20Menu%20Material%20theme
I don’t have my screen yet but I’ve been looking and reading. I think it’s the BIGTREE_TFT35_V3.0.26.x.bin and then everything in the tft35 folder
That might get your screen working again
