Has any one ever had one of their limit switches from Carbide 3D break? The other 3 are you XY&Z limits. 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. Insert a 5mm button head cap screw (#15) through the Shapeoko 3 Z-axis carriage plate from the back. 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. I'm leaving the three spare inverting buffers unused (they could be used for a probe, for instance). Solution: Adjust the end of the drag chain to be further away from the Y-Axis left plate. The mechanics of triggering them was more difficult to figure out than the wiring. Shapeoko 2 -- X Home/Limit Switch Mount Cups, Discs and Washers for Rare-Earth Magnets 3D printable mount for the Z switches Shapeoko 2 -- X, Y, & Z Home/Limit Switch Mounts with no reduction in cut area Limit Switch 1. Shown below is the location of all 3 homing switches mounted on your machine (X, Y, and Z). I checked my order history (thank you amazon) and this is the third z-limit switch this has happened to. 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. Most have the levers on them that could be cut off. When you move the carriage up by hand can it close the Z-axis switch? The switches are all mounted on the back sides so hopefully this won’t be a huge issue. The switches are designed to mount using a screw and have tabs that are supposed to fit in a slot. Just did a quick search. Here's an example of a proximity switch for the Z-axis: They can be used as an (almost) drop-in replacement for the original switches, the only difference is that (depending on their technology) they may need an additional lead for power supply, connected to one power pin of the controller board (typically, the 5V pin on the Arduino ISP header, see Anatomy of a Shapeoko for details). This is a prerequisite for utilizing the work (absolute) coordinate system, which is vital for double-sided machine work and… The flags are bent out of plumbers strapping. New Front and Back Plates New Cross Members Longer Extrusion(s) Longer Bel The flags are bent out of plumbers strapping. Commands for Grbl Note that these may be included in G-code files intended to only be sent to a machine running Grbl Hello Guys, Ive designed an Proximity Homing/Limit Switch for the Contactless switches that work with the Shapeoko TL-W5MC1-5mm-3-Wire-Inductive-Proximity-Sensor-Detection-Switch-NPN-DC-6-36V-YT (wire connection Brown 5V / Black Signal / Blue ground) The upper Holder uses the standard mounts to hold the switch. Connect a wire to each pin that, BAM, you have a probe. I like to have zero in the lower left of the machine so all movement is in the positive direction, so I flipped the X axis bit by setting $18=128. The Z axis actually turned out kind of slick – I ended up only using one switch. 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. 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. That worked out pretty well, so I repeated it on the other end. As the machine is in repair-state, I have more time for “research” and something like this might be just the ticket. This is an old ver board, but they are all very similar (regarding the Probe pins). The next step was to hook up some wires to the GRBLShield and attach a switch and see what happens. I also added a .1µf capacitor across the power lines near the X and Y axis switches. 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. They were all of $1.44 each. 03 - Y-Axis Idle 04 - Y-Axis Motor 05 - X-Axis Motor 06 - Z-Axis Plate 07 - X/Z Plates 08 - Gantry 09 - Z-Axis 10 - Spindle 11 - Rear Frame 12 - Main Frame 13 - Mount Z-Axis 14 - Electronics 15 - Configure GRBL 16 - Hello World! It’s really that easy. Now insert the Limit Cable's Pin 3 wire (White) in to to the terminal marked as "F" on the Z axis's Rail Connector. So when the limit switch is depressed, it will short the circuit to ground and the controller will know its at the ...limit. This is the wiring on the X axis motor plate. The limit switches are kind of fragile. I know this is an old topic, but these are the worst limit switches ever. Thanks, https://www.beavercnc.co.uk/product-page/beavercnc-precision-limit-switch-kit-for-shapeoko-3. Ok you should be able to see one button above called "PROG" and on the other end of the board there is another called "RESET" see picture below. I suppose my hesitance was related to all the people on the forum posting about issues with limit switches. Ensure all 4 wheels are in That is, if I zero the Z axis at the top (where it hits the limit switch), Carbide Motion lets me jog it down 3.1" before stopping and saying that a limit switch … Wiring diagram for ShapeOko 2--- grbl 0.9 includes: probe, relay wiring, limit switch wiring and Arduino USB to PC on-board USB wiring. 3.175turns/inch precision ground lead screw. Shapeoko 3 Z-axis The Shapeoko 3 uses a belt-driven Z-axis, requiring an endless loop 6mm wide GT2 belt. Which means that the minimal movement that the Shapeoko can theoretically do in any axis is 1/40th of a mm, that's 0.025mm or 0.001''. The connectors are the IDC (insulation displacement contacts) type, so I just used a small screwdriver to push the wires into the contacts. a) GRBL AIO (Arduino + Drivers + Filters + more Shop with confidence. It uses photographs of an XXL to attempt to describe how to assemble all three current Carbide 3D machine variants. But once I figured out how they worked, it was pretty easy. It seems to happen after the machine is not used for a few weeks. This caused my first issue. There is 1 home switch per axis of your machine (3 total). (I tested this.). I just learned this!!) 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. If you’re having problems homing your machine, the limit switches are the first thing to check. Got a new laptop, downloaded C motion, plug in and initialize with no problem. Unfortunately, those won’t work on the X or Z axis, so back to the drawing board. Hoping perhaps their quality is somehow different from the ones I got on Amazon.

Instead of holding down PROG key, simply hold the Z axis limit switch while programming. [by “break right off” I mean “right when I start a job”, not as in “off” the machine]. The cat 5 cable has 4 twisted pairs in it. There's a few things that might cause a limit switch fault on any 3d CNC controller to troubleshoot: I did swap it. Hello Guys, Ive designed an Proximity Homing/Limit Switch for the Contactless switches that work with the Shapeoko TL-W5MC1-5mm-3-Wire-Inductive-Proximity-Sensor-Detection-Switch-NPN-DC-6-36V-YT (wire connection Brown 5V / Black Signal / Blue ground) The upper Holder uses the standard mounts to hold the switch. Limit Switch Kit Assembly 4. Instead of holding down PROG key, simply hold the Z axis limit switch while programming. ready for your nema 23 motor. Belike this could be replaced by a length of belt and a clamp which could be affixed where the fixed pulley is placed. Installing a Homing and Limit Switch Kit - Shapeoko Project #48 - Duration: 5:25. Unfortunately, those won’t work on the X or Z axis, so back to the drawing board. Over all, adding limit switches wasn’t nearly as much hassle as I expected and it should make using the machine much simpler since I’ll have a repeatable automatic zero. The Z-Axis homing switch plate attaches to the front of the X/Z assembly using four (4x) M5x10mm button head cap screws. These are connected to one side of your normally open limit switch. I’m now playing the waiting game for the replacement from mouser to arrive. 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 This full revolution requires 1600 microsteps, which means that it requires 1600/40 = 40 steps to move by 1mm. Probe . SHAPEOKO 3 SQUARE LINEAR BEARINGS slider. 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. Completed Assembly from Step #3 2.) They set me back a whole $0.33 each. This is what the Y Axis ended up looking like. I show you how to fix it! I mounted the switch in the middle of the plate and made two flags that can be positioned on the Z rail. Convert your standard Shapeoko 3 to a Shapeoko XL or Shapeoko XXL. $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. Everything worked great for three or four jobs, and now the Z axis limit switch doesn’t work. Just bolt it … If I manually press the limit switch twice while it is trying to home it then homes the other two axes perfectly. I used one pair to run 5V and then used one wire from each remaining pair to run a signal line for each axis. Original Z-bracket could interfere with motor, updated it it prevent such issue. I used a cat 5 network cable that had stranded wires in it. Find great deals on eBay for Micro Limit Switch in Electrical Limit Switches. We’ll see. I ordered five. I took it off, and the “button” is broken off inside the little cover. Shapeoko accepts standard gcode so you can use almost any CAM software. Assemble the Switch Plates Note the cables are color coded for easier assembly. Z-axis will move up (in the positive direction) until the switch is contacted. Retighten that terminals screw. they are very fragile.  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. Y-Axis Rail Assembly You will need: 1.) I was not sure which pins on the GRBLShield to use so I poked around on the forum for a while and found some drawings that seemed to indicate that you should use pins 8, 9 and 10. Electronic failure, as in the switch is stuck on. The red/black cables go on the X and Z-axis… Has any one ever had one of their limit switches from Carbide 3D break? I mounted the switch in the middle of the plate and made two flags that can be positioned on the Z rail. Once I figured that out, it worked as expected! I bought the switches when I bought the machine, but never wired them up. 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. Insert a 5mm button head cap screw (#15) through the Shapeoko 3 Z-axis carriage plate from the back. 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. The standard kit includes everything you need to get started except the Dewalt trim router. Brackets for mounting micro switches on the Shapeoko 3 - updated Z-limit bracket.
