Printing fine details without the tool crossing the part? - sh.itjust.works

I’m trying to print a small 1-walled part with fine details. If I just model and print it in PrusaSlicer, the travel moves cross through the middle of the part and leave strings. “Avoid crossing perimeters” does not help: [https://sh.itjust.works/pictrs/image/404344d9-241a-40bc-aed7-dd3b329bc496.png] I’m playing with a really hacky solution, where I model the desired tool path in vase mode, and post-process the gcode to disable extrusion for straight walls at particular angles in the x-y plane. Here is the result: [https://sh.itjust.works/pictrs/image/7f57daea-7544-42d7-8da7-fcb8a6dd0ff1.png] This is effectively “vase mode with gaps” but my implementation is hideous. Does anyone know of a better way to prevent travel moves from crossing the part? Perhaps a different slicer or settings?

J3400 to J1772 adapter + DCFC = ??? - sh.itjust.works

I have one of these J3400 to J1772 adapters so I can connect my Hyundai to a Tesla destination charger. They’ll probably get more popular as J3400 becomes the primary standard: [https://sh.itjust.works/pictrs/image/64d55970-6169-41f3-ac15-880c52ccde6d.png] I’m curious what would actually happen if someone were to use such an adapter with a J3400 DC fast charger. I know it can’t possibly work because the DC charging pins are connected to the vehicle’s AC pins, but is there something in the J3400 standard to notice and reject such an adapter before DC voltage is applied? I’m not sure if J1772 vs. CCS1 adapters contain anything that the signalling protocol could use to identify which is which. If the DC charger were required to passively measure the battery voltage before sending any power, that would probably avoid the “magic smoke” problem, but does the standard guarantee that this will happen?
