I have seen both issues, when the sketcher starts to play up sometime I add more constraints to try to "anchor" a tangent in a certain direction but it can make the sketch messy The most reliable way I've found to stop it is small incremental changes e.g. say I want the length of a part to change my 40mm I'll change the size in 5mm increments allowing FC to recompute the model between each step. It's fiddly and frustrating but I can live with it, once you get to understand it's quirks Freecad can be very useful

I use the spreadsheet to hold dimensions/variable and formulas, makes it easier to modify designs. If I want to change a length, hole size height etc just change the spreadsheet values don't have to mess around with the sketches or 3d part designs directly.

One slightly frustrating thing i found is sometimes it fails to recompute the design or processes it incorrectly when values are changed by large amounts, that's probably more to do with how I design things though

That's strange, are you using Hugo to generate the site? I am currently using jekyll, it seems to put the full post into RSS content field and the summary text used on the home page in the RSS summary field. I have tried Hugo in the past and might switch to it, haven't tested its RSS generation though

Thanks. It's a shame personal blogs are dieing off, although I have seen a bit if a resurgence of them since github io pages have been a thing. I have also found that people use mastodon a lot to microblog/provide updates to new posts on their personal sites so there is hope I'VE updated the RSS link so it's at the top as well so its easier to find

Interesting posts you have there I also have also tired github.io pages (https://jackdavies.github.io) I've had it rattling around for a while post to it now and again. I want to use it more (still learning how to use its quite basic and probably broken in places) I've got some more projects/posts I want to put on it but currently updating the whole thing to separate posts/projects and improve the overall look and feel. Often struggle with time and motivation to work on it though
