![]() I have had the Cutty Shark runing for about three months now. I have finally overcome all the software learning curves. Way past time for a final update on this one. I am not any good at all with electronics, but if I'm having a problem with these, I would think the resistors is where its at.Īnymore input? High or low at this point would really help. If I have used the wrong resistors, then these won't be within tolerances that will activate a high or low difference enough to register. When open they aren't getting the ground. When closed they are getting 5 volts through the resistor and ground. This is where the resistor comes into play. The limit switches are in series because both are on the same pin and linked common to the NC contact on the next. They each are actually a separate circuit using a different input pin. It says its parallel to each other, but its not really, I don't think. Here is the link to the PDF with the schematic for the Homers. It seemed a little odd to me to call it parallel. Z unlike x and y has no physical limit switch and x and y are in series. There is a little room for fluctuation here. On my z however, the home is at about 4 with the actual top of z set in software limits at +4.5 or so. 5" ast there at the actual limits at -0.5". I have my home switches on x and y at zero and set the software limits. I used some regular old 10k resistors from Radio Shack. I have the 3 axis Xylotex and installed according to Jeff's schematics on the site. My problem has been with regard to getting the switches to actuate or get Mach 3 to acknowledge actuation. ![]() I am evaluating Sheet Cam and think it looks and works well with Mach3. So far, it has only cut out the Roadrunner from Mach 3's program. ![]() I did build an detatchable dust collection sheild for it. ![]() I am installing the Homers and limits now. ![]()
