The new Linkage 3.5 is now available. It has connector settings to make a rotating input anchor oscillate between two angles (the first always being zero) with a settable starting position that also gets set automatically when pinning the mechanism. There is also a new start position setting…
Continue readingGet it here: https://blog.rectorsquid.com/download-linkage/ I just added an Oscillation Limit Angle to the connector properties. If set to something above zero, the input will oscillate back and forth to that number of degrees and back. This number is always positive so you must use the RPM value sign…
Continue readingLast week, I spent an evening fixing some bugs in the Linkage program. It’s a bit buggy since I added a bunch of complicated features like gears and fastening. Writing software is hard to do well but not hard to do badly. I once had to tell someone,…

Continue readingI’m not sure what to call them. On an actuator, there is a small circle that can be used to change the throw length. That little circle is an adjuster knob or adjustment controller or something like that. I’m working towards in-mechanism editing of cams and changing the…
Continue readingA new version is available in the usual place. I was finally able to spend the hour needed to fix the crash that happened when deleting links that were fastened to gears (or vice-versa). Version 3.3.13 has this fix. A few other changes and fixes: You can now…
Continue readingThe whole “fastening” thing is a bit troublesome for me. I originally wanted to be able to move drawing elements with links and decided to allow “fastening.” This worked pretty well, though there is a bug where deleting a fastened element somehow causes a crash. But fastening isn’t…
