20after4 added a comment to T13652: Notes on Ardunio CNC drivers.

I'm starting with an absolute bottom-of-the-line 3018, I've "upgraded" it with a plotter collet I made out of a pool noodle and a piece of cable gland so I'm less likely to hurt myself for now:

179844809_10107947618735199_738255650651003118_n.jpg (935×526 px, 71 KB)

So far, I've mostly been implementing controller software, following heavily in the footsteps of GRBL. I think I'm maybe ~25% of the way toward having a similar-ish capability set? But I don't really know what I'm doing, I am doing a few things a bit differently, and haven't written any meaningful amount of C in many years, and suspect I may run into a wall with the CPU.

One thing I've changed is that the computer tells the board what hardware it is connected to at startup, e.g. "Linear Stepper Axis 1 is enabled by pin 8, driven by pin 2, and direction is controlled by pin 5", since I'd like to be able to rewire the board without updating the software, and generally have more control over the hardware configuration, and have an arbitrarily large number of axes and actuators and blinking lights and whatnot. My motion commands then reference axis IDs ("2D linear motion on axis 0 and axis 1 to relative position 15, 35") instead of spatial axes like "X" and "Y" directly.

Now that I realized this isn't an April fools joke (or if it is, it's kinda late...) anyway I have a whole lot of experience in this department, having built several cnc controllers. My latest one is using a beaglebone black but I also experimented quite a lot with an arduino running grbl and another one running on a $30 esp32 board. If you have any unanswered questions I'd be happy to comment. I should have slightly better than ignorant responses.

This would be incredibly useful for the things we are trying to do at WMF. I've gone so far as to duplicate lots of forms for each subtype and remove fields as needed. This results in N * N forms and it's not at all manageable beyond a very small number of sub-types.

It seems to be a fairly recent problem so there must be some code change that started triggering it. The worst part, IMO, is that the workboard breaks in a not-entirely-obvious way instead of falling back to a default query. It took me a while to debug the issue the first time it occurred.

D18836 probably isn't the right solution, however, it's the only straightforward fix I could come up with. I didn't dig into the details of why it 404s when I fix the code in PhabricatorProjectViewController to avoid the fatal. The patch is probably good enough for Wikimedia, however, I'm not sure if it's good enough for upstream.

Another approach that might make sense would be to highlight the hash and then show a hovercard which lists the commits with that hash. Of course this wouldn't scale too far but it should handle the case where 2 or 3 commits have the same hash.

I tried to work around the immediate fatal by checking the return value of $engine->getDefaultItem() in PhabricatorProjectViewController, however, that resulted in hitting a 404 so it's a bit deeper of an issue. Perhaps the right solution is to prevent users from disabling both of the default items in the project "manage menu" UI?

I don't see any easy way to cheat through $_FILES, though. We could remove it, but we have a nonzero number of users who compile their own copy of Linux and use a window manager that doesn't support drag and drop and disable Javascript and don't believe a monitor should ever have more than 256 colors, so that would leave them out to dry. The conversion also isn't trivial, so even if we want to move in this direction eventually I think it's a significant scope expansion over just building a synthetic $_FILES.
