*edit (NO, not NC for #4), Reversed NO for NC on #3 (see how easy it is to get those mixed up!). I will ohm out the switch to see if it failed. $130, $131, and $132 parameters respectively control X, Y and Z maximum travel : (carefully) jog to the limit of each axis, leaving a small margin you are confortable with, write the current axis value in millimeters, drop the minus sign, and set it in the corresponding parameter (e.g. The switch mounting plate is tilted in the wrong direction, causing the gantry plate to contact the hard limit. It is about 3/16” tall. With the way the table is setup (currently) the tool will bury itself through the table before the limit switch is even triggered so, _for now_, it will work. With the way the table is setup (currently) the tool will bury itself through the table before the limit switch is even triggered so, _for now_, it will work. The next pair of settings, Junction Deviation and Arc Tolerance rarely require change. The Shapeoko is a great machine out of the box, and there is really no need to modify it to get good results. The electronics work on 110V or 220v. 5. To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko.

Do I need to do something to reset up the machine with the new laptop? This distance is about 1.5 times the max travel of the axis. If I manually press the limit switch twice while it is trying to home it then homes the other two axes perfectly. All wires have crimped terminals and headers, and are color coded for easy attachment. Let us know how it turns out or if you need some help. ALARM:9 indicates "Homing fail. I double checked and made sure the switch is plugged into the appropriately labeled wiring, even unplugged and replugged everything. As shown in the documentation. So I'll limit my comparison to the two points below: Whereas the… Homing fail occurs in two scenarios. Shapeoko comes with an industrial-grade motion controller running GRBL firmware, homing switches, and 4 NEMA 23 stepper motors. The most affordable and capable bench top CNC router kit available. Try increasing max travel, decreasing pull-off distance, or check wiring." @ThomasDalgas: ALARM:9 is totally different from error:9. It goes between the fan and the input control cable. If not, the RF from the servo motor wiring will induce a current in the limit switch wires -tripping the circuit. Must be tolerance stack up on the HDZ because mine engages just fine…the only issue with mine must have been that it failed before the machine homed. First it was my Z limit, which Carbide was nice enough to send a replacement for. I also had to put a block of plastic w/ two way tape on top of the z axis carriage because the homing/limit switch was not being engaged. This is … It most definitely is bad. The problem with that one is I am having the hardest time finding a place to mount it. I am using the Lightburn software to run the laser as that is what JTech recommends but after I follow the set up instructions, Lightburn does not find my laser. Need assistance. No, really, check out Winston Moy's videos if you need convincing. Available in 3 sizes. I went through some troubleshooting steps on the Carbide website and have not been able to make any progress. Then it gave me a Z limit switch error. Still, once you are reasonably comfortable with the machine, and how to set optimal CAD/CAM parameters, chances are you may be tempted to optimize the machine itself. Listed below are several common problems found during home switch installation and initial setup. All of the rest, which is the entire Shapeoko kit, along with the parts to upgrade everything to a Shapeoko 2 (stiffer z axis gantry, new belts all around) plus other enhancement parts I never got around to using - including those needed to make a control box with detachable cables, limit switches, emergency stop button, etc. To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. Could not find limit switch within search distances. I had a limit switch issue that turned out to be largely due to outdated assembly instructions on the Carbide 3D website. That’s interesting, I wonder what is different. I had just the X limit switch plugged in, when I pressed it the corresponding X LED light lit up blue. I finished adding all the limit switches to the shapeoko except for the z-. After looking at the limit switch, the little pin had been sheared off and the switch was crooked. This is a GREAT Idea ... and did not even cross my mind to try. Starting at $1320. Does the carbide 3d like them wired normally open (NO) or Normally Closed (NC)? Winston Moy 36,048 views.

(These are pins 9,10 & 12 in Arduino Talk) When you hit a limit switch, the limit switch connects/shorts this pin to ground causing the voltage on this pin to rapidly drop from High State (5V) to Low State (0V/GND). Open loop means that there is no feedback to the controller. Symptoms: The console window will show the command being sent and a confirmation of "ok".However, the active state goes to "Queue" and never returns to "Idle." This is getting overly frustrating because I cannot use my shiny new probe without GBRL 1.1, and I can’t use that without homing, which I can’t do without working switches.
