For the X Axis I bent some more flags out of plumbers strapping, but I had to put a 90 degree twist in them. 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.). I’m sure with further searching you could find the correct one. Limit Switch Kit Assembly 4. Please make sure that the machine can mechanically close the appropriate homing switch on an axis before reaching the limit of travel along that axis … 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. Shown below is the location of all 3 homing switches mounted on your machine (X, Y, and Z). 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. This is a prerequisite for utilizing the work (absolute) coordinate system, which is vital for double-sided machine work and… To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. Instead of holding down PROG key, simply hold the Z axis limit switch while programming. Electronic failure, as in the switch is stuck on. They are 3D printed, accept standard limit switches and bolt directly onto the … I had to actually call DigiKey to find the correct connectors for these switches – part number 2-179694-3-ND.

Next came the flags to trip them. made for precision and rigidity if you don't want "chatter", use this slider!! It homes. The Z-axis is limited in its acceleration and top speed by the torque of the motor. Shapeoko XXL not jogging more than 4mm in X or Y but works in Z, initializes X, Y, and Z no problem. Just bolt it … To protect his machine from human error, [Zorlack] decided to make limit switch brackets for his Shapeoko. If it is able to move down okay, but will not move up reliably, then the acceleration or movement may be too fast or high. Posted by 1 year ago. 7" travel. On the X and Y axis the signal lines for both switches are tied together in parallel. Once the wiring was all done, I fired off a homing cycle. home switch included . One possible issue will be if I get false limit switch trips due to swarf getting into the switches. They were all of $1.44 each. These are 5V logic level switches. The kit includes everything you need. 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. 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 … Solution: Adjust the end of the drag chain to be further away from the Y-Axis left plate. Shapeoko. I mounted the switch in the middle of the plate and made two flags that can be positioned on the Z rail.

Link? Add to that they are $6+ a pop, plus shipping. I show you how to fix it! After I got the mechanics all sorted out, it was time to do the wiring. I also added a .1µf capacitor across the power lines near the X and Y axis switches. Having problem with limit switch hit. The switches have a repeatability rating of .3mm (.012″) which is pretty good. Here's more or less how I have my limit switches wired. This is the wiring on the X axis motor plate. The Shapeoko uses our Carbide Compact Router or you can provide your own DeWalt DWP-611 or Makita RT0701C as a spindle. The Z axis actually turned out kind of slick – I ended up only using one switch. I used a cat 5 network cable that had stranded wires in it. I did the XXL upgrade last week and installed the limit/homing switches (after having to adapt it to my Ver1 end plates). Completed Assembly from Step #3 2.) I mounted the switch in the middle of the plate and made two flags that can be positioned on the Z rail. 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. The Z axis actually turned out kind of slick – I ended up only using one switch. I’m now playing the waiting game for the replacement from mouser to arrive. The ones that came with my machine seem to be Omron D2QW-C003H. I cut some 3/8″ wide pieces of aluminum angle and applied foam tape to the back – again, no load. Searched “micro limit switches”.

I was willing to accept one as my fault, one as a bad part, but at three, I’m suspicious. 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. This usually results in a grinding noise as the hard stop engages while trying to find the home switch. Unfortunately, those won’t work on the X or Z axis, so back to the drawing board. I just learned this!!) [by “break right off” I mean “right when I start a job”, not as in “off” the machine]. Everything worked great for three or four jobs, and now the Z axis limit switch doesn’t work. I'm leaving the three spare inverting buffers unused (they could be used for a probe, for instance). The cat 5 cable has 4 twisted pairs in it. Reed switches or hall-effect switches? The connectors are the IDC (insulation displacement contacts) type, so I just used a small screwdriver to push the wires into the contacts. Just did a quick search. There is no real load or force on the switches, so they should stay attached (I hope.). Insert a 5mm button head cap screw (#15) through the Shapeoko 3 Z-axis carriage plate from the back. You can build it in about 2 hours. It uses photographs of an XXL to attempt to describe how to assemble all three current Carbide 3D machine variants. When you move the carriage up by hand can it close the Z-axis switch? 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. 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. You can do this without removing the plate if you use a needle nose pliers. One for the X axis, one for the Y axis, and one for the Z axis. You could move to electronic - non touch switches like I did? Original Z-bracket could interfere with motor, updated it it prevent such issue. Limit switches allow for a consistent and repeatable origin. There's a few things that might cause a limit switch fault on any 3d CNC controller to troubleshoot: I did swap it. As the machine is in repair-state, I have more time for “research” and something like this might be just the ticket. Any body have a good Amazon link for a switch? The switches are designed to mount using a screw and have tabs that are supposed to fit in a slot. All included software runs on your Mac (10.9 or higher), or PC (Windows 7 or higher).
