they are very fragile. When one switch gets tripped it will pull the other low. You can do this without removing the plate if you use a needle nose pliers. Shapeoko 3 Z-axis The Shapeoko 3 uses a belt-driven Z-axis, requiring an endless loop 6mm wide GT2 belt. I suppose my hesitance was related to all the people on the forum posting about issues with limit switches. I didn’t feel like tearing down the whole machine to drill mounting holes, so I cut off the tabs and put some double-stick foam tape on the back. Finally I stuck my multimeter on the pins and realized that pin 8 was low all the time, while 9, 10 and 11 were high. For the X Axis I bent some more flags out of plumbers strapping, but I had to put a 90 degree twist in them. The Shapeoko's limits must also be accounted for: the absolute maximum theoretical chipload on a stock Shapeoko would be reached when using a single-flute endmill at the lowest RPM (10,000RPM on the Makita router) and at the fastest feedrate of 200 inch per minute, and that would be … Connect a wire to each pin that, BAM, you have a probe. Cutting Area (XL): 33"(X), 17"(Y), 3"(Z) Cutting Area (XXL): 33"(X) x 33"(Y) x 3"(Z) The kit includes everything you need to convert your standard machine to a larger version. I hooked one up to my multimeter to verify that this is what happens, and sure enough, it is. The picture is to show that the limit switch is getting touched by the z-axis plate. Everything worked great for three or four jobs, and now the Z axis limit switch doesn’t work. They are 3D printed, ... (Z axis) on my gantry. The Shapeoko is partially assembled. The flags are bent out of plumbers strapping. I just learned this!!) They seem to also have some sort of manufacturing gunk in them that requires them to be clicked a few times before the contacts wipe enough off to start working well. I've only shown the two X axis switches: Y and Z connect the same So when the limit switch is depressed, it will short the circuit to ground and the controller will know its at the ...limit. SHAPEOKO 3 FAQ *Thank you to Chris Powell from Full Steam Designs* SQUARE LINEAR BEARINGS .. $329.00 But when I try to run it Danes limit switch hit and I can’t do anything Value Mask X Y Z 0 00000000 N N N 1 00000001 Y N N 2 00000010 N Y N 3 00000011 Y Y N 4 00000100 N N Y 5 00000101 Y N Y 6 00000110 N Y Y 7 00000111 Y Y Y This usually results in a grinding noise as the hard stop engages while trying to find the home switch. Shop with confidence. On the X and Y axis the signal lines for both switches are tied together in parallel. Then I go to jog to set zero and it only moves X and Y axis up to 4mm in each direction then it just keeps saying “busy” was just time I press the buttons. Shapeoko XXL not jogging more than 4mm in X or Y but works in Z, initializes X, Y, and Z no problem. It seems to New Front and Back Plates New Cross Members Longer Extrusion(s) Longer Bel Most have the levers on them that could be cut off. shapeoko 3 z-plus The Shapeoko milling machines are designed by Carbide 3D to be affordable enough for any shop and powerful enough to do real work.

Thanks, https://www.beavercnc.co.uk/product-page/beavercnc-precision-limit-switch-kit-for-shapeoko-3. Everything worked great for three or four jobs, and now the Z axis limit switch doesn’t work. The other 3 are you XY&Z limits. The connectors are the IDC (insulation displacement contacts) type, so I just used a small screwdriver to push the wires into the contacts. Got a new laptop, downloaded C motion, plug in and initialize with no problem. I bought the switches when I bought the machine, but never wired them up. Retighten that terminals screw. Make sure the limit switch is located in the bottom left corner of the plate (when viewed from the front of the Shapeoko XXL) before securing to the standoffs. All included software runs on your Mac (10.9 or higher), or PC (Windows 7 or higher). One possible issue will be if I get false limit switch trips due to swarf getting into the switches. I did fire up the spindle and move the X and there were no issues, but I need to fire up the spindle and the vacuum and then run a program to make sure. The drag chain is at an angle towards the front of the machine. (I tested this.). Buy an expansion kit any time to upgrade your Shapeoko 3 … With the new Z plate on, I’m to move the Z axis 3.1". Limit Switch Kit Assembly 4. Check and make sure each Rail Connector has one signal wire and one common wire connected. I had supposed it had gotten gummed up with small particles and during previous failures and I had tried fiddling with the switch for a few minutes (which according to the s.o. If I manually press the limit switch twice while it is trying to home it then homes the other two axes perfectly. I had to actually call DigiKey to find the correct connectors for these switches – part number 2-179694-3-ND. 7" travel. These are connected to one side of your normally open limit switch. 1. You attach 5V and GND and the third wire is High (5V) until you block the sensor, then it goes Low (0V.) a) GRBL AIO (Arduino + Drivers + Filters + more Grbl v1.1 changed the Z axis homing switch connection to a different pin, and it make a lot of Z switches inoperable. Just did a quick search. Shapeoko XXL not jogging more than 4mm in X or Y but works in Z, initializes X, Y, and Z no problem. End Stop / Limit Switch Problems: UPDATE: There are now several easier alternatives than the G-shield and CNC shield which have built in filters amongst other features. Install in the order shown below. Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), The (Almost) Final Chapter in the Saga of the LuvBus. Shapeoko.  The second flag is mounted to the rail since the spindle hangs on that side so the machine has to stop well before the end of the rails. Add to that they are $6+ a pop, plus shipping. It seems to happen after the machine is not used for a few weeks. Each limit switch is attached to a twisted-wire pair of black and yellow wires. Unfortunately, those won’t work on the X or Z axis, so back to the drawing board. The community maintains a list of parts and other notes on the machine: http://www.shapeoko.com/wiki/index.php/Home/Limit_Switches#Shapeoko_3, http://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/D2QW-C003H/SW1221-ND/2698560, This may be a little late, but my Z axis switch stopped working on the second day of using my SO3 XXL. No issues with the axis’. Quite precise, ... Z-limit switch. This full revolution requires 1600 microsteps, which means that it requires 1600/40 = 40 steps to move by 1mm. Does the carbide limit switches have a probing capability, I have a S3 purchased prior to them coming with the switches, I like to know wich are better carbides our Andrews? The next step was to hook up some wires to the GRBLShield and attach a switch and see what happens. To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. I’m sure with further searching you could find the correct one. Here's more or less how I have my limit switches wired. I was inspired by this GREAT thing http://www.thingiverse.com/thing:257089 because I needed the Z axis mounts and I wanted them to all match. Convert your standard Shapeoko 3 to a Shapeoko XL or Shapeoko XXL. But if you’re still under warranty, no need to purchase them — contact [email protected] and we’ll send you some.

Review the items below to help you identify what could be causing your limit switches not to trigger. Has any one ever had one of their limit switches from Carbide 3D break? That worked out pretty well, so I repeated it on the other end. I found a spare that I had for my 3D Printer and am using that for now, but the mounting holes don’t line up, so its just Zip-Tied on for now. Limit switches allow for a consistent and repeatable origin. As the machine is in repair-state, I have more time for “research” and something like this might be just the ticket. I took it off, and the “button” is broken off inside the little cover. UPDATE: (You don't have to do this if you have limit switch on the Z axis. If I manually press the limit switch twice while it is trying to home it then homes the other two axes perfectly. I’m now playing the waiting game for the replacement from mouser to arrive. Hoping perhaps their quality is somehow different from the ones I got on Amazon. Thanks for the help Will! We’ll see. After I got the mechanics all sorted out, it was time to do the wiring. Belike this could be replaced by a length of belt and a clamp which could be affixed where the fixed pulley is placed. Instead of holding down PROG key, simply hold the Z axis limit switch while programming. Cutting Area (XL): 33"(X), 17"(Y), 3"(Z) Cutting Area (XXL): 33"(X) x 33"(Y) x 3"(Z) The kit includes everything you need to convert your standard machine to a larger version. I just learned this!!) well i have had the same problem with shapeoko limit switches. The pulleys used on the Shapeoko 3 happen to have 20 teeth, with (obviously) the same 2mm spacing as the belt: so when the shaft does one full revolution, the belt moves by 20 teeth, i.e. Has any one ever had one of their limit switches from Carbide 3D break? I don’t know how I missed that post with the link to them. Probably good enough for most of what I do, though I might run some tests later to see what actually happens. I'm leaving the three spare inverting buffers unused (they could be used for a probe, for instance). I also added a .1µf capacitor across the power lines near the X and Y axis switches. E-stop . I seem to have forgotten that the Y axis needs inversion also, so I’ll have to change that the next time I use the machine (tonight most likely.). Y-Axis Rail Assembly You will need: 1.) A limit switch is pretty basic, and usually repeatable thousands of times. Then when I restarted to home it again, poop. Where can I order new switches (without the wiring) so I can keep a few on hand if this happens again? Once the wiring was all done, I fired off a homing cycle. Connect Z-axis motor (known good) to X-axis wiring extension (unknown if good or bad) to Z-axis stepper driver (known good) Y-axis not working properly This can be tricky to puzzle out since one motor can move the gantry --- usually best to connect, home, slacken/remove belts, attach bits of tape to the pulleys, then test. The switches are designed to mount using a screw and have tabs that are supposed to fit in a slot. Wiring diagram for ShapeOko 2--- grbl 0.9 includes: probe, relay wiring, limit switch wiring and Arduino USB to PC on-board USB wiring. The switches are all mounted on the back sides so hopefully this won’t be a huge issue. One for the X axis, one for the Y axis, and one for the Z axis. made for precision and rigidity if you don't want "chatter", use this slider!! The switches are pre-installed to their respective plates during the harness assembly in the factory. And, yes, I will be contacting carbide 3d support, but I am still waiting to hear back from them on two other non related issues, and still waiting on the replacement motor extension that was DOA that was shipped Fedex Ground…. The Shapeoko 3 limit switch kit from Carbide 3D provides an easy and reliable way to add limit switches (home switches) to your current setup. The Z-axis will then back off slightly before re-engaging the switch and then backing off for a final time and setting the Z-axis to machine origin ― this will display as Z=−5 (the 5mm away from the machine origin that the machine backs off after homing) until an origin is set I was willing to accept one as my fault, one as a bad part, but at three, I’m suspicious. There is no real load or force on the switches, so they should stay attached (I hope.). Please see http://docs.carbide3d.com/software-faq/home-switch-troubleshooting/. Reed switches or hall-effect switches? When you attach a limit switch to pin 8, it gets pulled low no matter what you do. I used one pair to run 5V and then used one wire from each remaining pair to run a signal line for each axis. Unfortunately, those won’t work on the X or Z axis, so back to the drawing board. The cat 5 cable has 4 twisted pairs in it. If that doesn’t help, contact [email protected] and we’ll try to work out what’s causing this — it’s not a common problem/occurrence. The limit switches are kind of fragile. This is an unofficial addendum compiled by the community to the official sets of instructions. 2x 40” Extrusions With the eccentrics on both Y-Axis plates in the fully ‘open’ position, slide each rail through the carriages. Posted by 1 year ago. I like The Z axis actually turned out kind of slick – I ended up only using one switch. Commands for Grbl Note that these may be included in G-code files intended to only be sent to a machine running Grbl Completed Assembly from Step #3 2.) The Z-axis is limited in its acceleration and top speed by the torque of the motor. The switches have a repeatability rating of .3mm (.012″) which is pretty good. There is a set of pins on you GRBL board called Probe . I’ve lost two Z axis switches in about 8 months. Convert your standard Shapeoko 3 to a Shapeoko XL or Shapeoko XXL. Shapeoko accepts standard gcode so you can use almost any CAM software. It never was bumped or slammed into in those jobs, just used for homing and a couple of pauses. The standard kit includes everything you need to get started except the Dewalt trim router. The flags are bent out of plumbers strapping. It uses photographs of an XXL to attempt to describe how to assemble all three current Carbide 3D machine variants. home switch included . Instead of holding down PROG key, simply hold the Z axis limit switch while programming. Ok you should be able to see one button above called "PROG" and on the other end of … It seems if I don’t use my machine for a month or two they break right off when I fire it up – yes they have literally broken during a homing process. Some G-code senders have an option to limit the Z-axis speed. Z-axis limit switch Bracket Design: My design objective was to create a durable yet minimalistic X/Y/Z limit switch mounting bracket. I know this is an old topic, but these are the worst limit switches ever. I checked the troubleshooting guide and believe I’ve got (well not at the moment) the switch installed correctly. At the Arduino end I connected all the unused wires to the ground – I think this will help with shielding the signal, but I could be wrong. I’ve gone through several, all on the Z Axis, over the two years I’ve had the machine and I treat them very gently. was actually hours) to see if I could un-stick it to no avail. $3 for Grbl 0.9, default for Shapeoko 3: $3=6 (dir port invert mask:00000110) X axis is 1, Y is 2, and Z is 4.
