Will this be in the main documentation of the resource area on your website? I think this is a big benefit
Yes, you can find further resources and documentation for the kit here: resources.sienci.com/view/lm-adding-limit-switches/
These sensors are an awesome addition to the Longmill! So many possiblities!
Can wait for the ORDER page to be updated :)
This is great I wish y’all would make a tramming plate. That would make this machine so much easier to use.
Cant wait to order mine. I hope you guys do an in-depth Gsender setup, and a few cut examples for the noobs, not me of course nope not me ").

*** be very careful when you tighten bolts ***
Just set my switches up today and I don't have a tendency to overtightening but the 3D printed bracket on the X switch was pretty delicate and snapped. In no way did I feel like I had bottomed out the bolt, or that it was really gripping the rail.
I ended up using epoxy to attach the switch.
I am installing my limit switches now. I have some advice for them.
For the z axis, because m5x16 screws are not sent any more, the z limit switch is useless. The bolts that were sent with mine are too long and it interferes with upward travel anyway. I have to remove the screw and buy m5x16, which are shorter, so the upward travel will even reach the limit switch.
My conclusion is if limit switches are ordered in addition to the machine m5x16 bolts should be sent like in the original installation video otherwise switches are useless (or should be at least in printed instructions with the switches to inform customers of this. Luckily I watched a garret fromme video)
Where do I find the brackets to attach the limit switches
Hey Dwayne, please check out our resources for additional installation instructions resources.sienci.com/view/lmk2-limit-switches/
Hi Guys thanks for the Vid! if I didn't have a high powered Laser id buy this one to go along with my Longmill. Question anyway you guys can do a nice video of squaring the machine up. I've followed the instructions and had it square now for like 6 months. now I'm slightly off and no matter how many times i follow your instructions I'm still not getting straight lines. Might be helpful to see what alternatives you have to square it up that might help
If you'd like, there's a tool available in gSender that you could try out which helps with the squaring process. Have you given this a shot yet?
-Chris
@@SienciLabs Thanks Chris, looking at your "gSender Guide, Tips, and FAQ" to see if see ifyou mention it.
Yes now that I see the documentation, I did the ‘Calibration Tool’ and told me i was pretty square but my left to right cutting still goes up slightly but noticeably, and this is new like in the past month so far its been great.
The problem with the E stop is because it is just a power switch and does not throw an alarm. If the E stop were wired to the actual stop button it would not continue running the program in the software.
Can you figure out how to do this and then teach me 👍
@@klm8156 Haven't worked on my Longmill in a while but want to get back into it. Been saving and working on a better table design featuring a 4' x 4' metal tabletop and and lots of drawers / cabinets for tooling and electrical control storage. Also trying to get a lighter spindle because my 2.2kw spindle is too heavy and flexes the gantry due to its poor rigitiy in the design.
@@vivigarr keep us posted!
@@vivigarryou say the Longmill is poorly designed and lacks rigidity?
is this going to be included with full kits? If so, any way we could have them sent out if we bought a kit in the past couple weeks?
It's a 48$ us add-on. So I doubt it's going to be included
I ordered an MK2 and wasn't included...everything is an add-on...
Could someone please answer this for me, perhaps I missed something on the video. Why only 3 limit switches and not 5? One for the Z, two for the Y in front and back and two on the X on both sides instead of 1 on each axis? It did the say that one of the purposes of the inductive sensors were to prevent damage, so would it not make sense to add the additional sensors to do just that?
Protection can certainly be accomplished with 5 sensors or even 6. Using only this approach employs 'hard limits' which restricts machine motion from collision on both sides. Another proven approach is 'soft limits'. This means only 3 sensors need to be set up, as well the machine is told what the limit of it's travel is in its firmware so that once it reaches that distance it will stop itself from moving further. This means that the machine is still protected from moving too far, but only half the sensors are needed which reduces the likelihood of things going wrong and reduces cost.
Hi, if I need to move the shaft to the opposite side where the sensor is installed, will the machine stop to avoid damage, For example I have installed the Y sensor on the left/front side, if I move it to the left/back end it will stop? or will I have to install sensors in every corner as if I had a mechanical limit switch, sorry for my stupid question. thank you so much.
If you're using 'soft limits' then you only need sensors on one side. The reason it won't hit on the other side is that if you 'home' the machine, there are numbers that tell it how far it can go in each direction, once it reaches that amount the software inside the CNC won't let it move any further. Does that make sense?
Hey guys when can we expect a 4th AXIS OPTION.
no current devs on 4th axis yet
they are inductive proximity switches same thing.
Inductive sensors and inductive proximity switches are the same thing 👍

Does this sensor kit work with the New MK2?
The MK2 has it's own unique sensor kit that mounts more easily but still uses the same sensors. You can check it out here: sienci.com/product/inductive-sensor-kit-for-the-longmill-mk2/
@@SienciLabs Thank you I am in the process of ordering the MK2 and want to make sure the add ons I am selecting are the correct items.
I left an earlier comment. Now I'm back cause I'm still thinking of that $47 I wasted for this and I want to include more info why this is a waste. I would like to think they are thinking and would like to rectify this for future orders (wire length and durable plastic).
Its a great idea but the planning is awful for this one.
First off, the plastic is not near as durable or rugged as the plastic for the 3d printed legs. It is quite thin. One of mine cracked just from tightening the screw onto the x-axis and it hadn't even tightened onto the steel portion yet. Didn't crack all the way through and I could probably even use it except that there is one more problem.
While the electrical wires for the control board are long enough to tuck the control box away off to the side of the table or in my case, underneath the table to keep clear of dust, they certainly aren't long enough for the x-axis limit switch. Wire is not sufficiently long enough to match any kind of length of wire that comes with the control board.
So as a result, I would have to plan ahead, not knowing anything about wires and connections, buy an extra wire with the same type of plug just to even reach the control board. So for now they are useless and I wasted my $47 plus tax!
Oh yeah, while I did have them hooked up I noticed that even though I did not have Gsender setup for the switches I noticed every time the x-axis came near the switches the red light would come on. Oddly enough, one of them never did come on cause I checked so I have no idea if it would work even if I did hook them up correctly.
Otherwise, I really like the longmill. I have been antsy all day cause my designing of a project didn't get through in time and my cut time for the project is 8.5 hours. I'll just have to wait another day to do it. However, I do believe if my limit switches had a long enough wire I could stop and start where I left off??? I have no idea cause I haven't even experimented with them yet.
iwannaapple, sorry to hear about the quality of your limit switches. I'm not sure why you're experiencing issues with the wire length since they should all be sized correctly - and as far as the plastic goes we've been working at ensuring good quality when shipping the kit out. Feel free to contact us and we'll make sure you get sorted out. As you noted the design could be improved which is what we did with the new MK2 where now the sensors are directly integrated into the machine steel plates to be very durable.
@@SienciLabs
Wow, that is awesome for the Mk2.
I ordered a touch plate. Ya'll were gracious enough to send me 2 replacements to replace the one that cracked. The replacements seem much tougher?? They are more like the feet with those tiny ridges.
As for the wire length: two of them ARE long enough to match the length of the controller wires. The x-axis (which is actually placed near the router) because of its location placement and how it needs to be routed TWICE through the cables will result in a wire that is too short to match the reach of the other wires thus completely eliminating any thought of tucking the control board away. That means I will be contacting y'all again because I need to buy another wire with a male and female ends so I can use the switches.
And I'm am glad you read my post. Hope you've made it this far because I have something else to say.
I am learning as much as I can about the cnc. However, I used to be a practicing programmer. I am not as good as I used to be but I still have the instinct and it is from my experience that I want to bring up a couple of more things.
Firstly, it is called USER INTERFACE for a reason. Fix what the user see's FIRST.
gSender is awesome but how about fixing the text box so it won't add numbers when I am trying to specify a jog. One function is overriding another function. If I want to type in .01 I don't want it to type in .011 by itself.
Or, how about terminating the download messages after a download is updated?? I have no idea if my gSender has downloaded ANYTHING because the downloading message simply will not stop displaying "Downloading". We need to know when it has stopped otherwise we don't even know when its started!??
And, why does your programmers have control over how much the bit travels past the touch plate to measure the x & y?
Give users control of that option. That would allow anyone to zero as large a bit as they want. But you say, "That is an irregular bit!". There is a simple solution to that too.
By the way, I used the touch plate. Love it! But I used a 1/16 bit. Because there is no user interface for control the router only measured at the widest point of the shaft and not the cutting diameter which I clearly entered the correct size. However, because of the lack of user control, the touch plate could NOT find the correct starting point in the lower left corner. The correct starting point was NOT found (not even close) Until I entered into the console Garrets Frommes formula. Which tells me that the programmers have not put "cutting diameter/2" in their programming code for irregular shaped bits (or for any bit for that matter)where the shaft is larger than the cutting diameter (the shaft touches the plate first.) or even where the cutting diameter is larger than the shaft.
But, doing it correctly would however eliminate the need for the newest touch plate.
I would have to say that I love EVRYTHING else. And most importantly, check for yourself if the wire is long enough to route through both cables and STILL reach the same length as the control box. Did someone not think of that?? Y'all so busy I think you forgot to check yourself. Even your you tubers admit to having to add a longer wire because of this (Buckys customs). I can copy and paste his message to me saying the same thing if you'd like. Please rectify this for your customers. Talk at ya later. Bye. Keep up the good work. I'm not complaining. Just giving you customer feedback
@@iwannaapple7190I guess they missed this message
That is not the kind of plastic that came with my limit switches that is shown in this video. The plastic in this video looks more rugged!
Cnc machine maestro
Why should new users not get these and experienced people should ??
Once the machine is set up to use the sensors there are now more things you have to keep in mind when running you machine as well as more things that could go wrong during troubleshooting. Since the benefit of having sensors is mainly for more advanced uses such as running multi-day jobs, Tiling, several-bit jobs, etc. then most new users can likely get along fine without them 👍

Would be nice if I could understand you, very hoarse
