I think I may be the only person who likes using toolboards with delta printers, but I find it really convenient to change between different tools, and for media that is less physically stable (clay), it just seems like the right kinematic system. I had been using a QQ-S Pro for many years, but when I started working with clay more last year, I wanted something with a stiffer frame. When I found the SR on mega sale over the last winter holiday, I snapped up a couple.
Last fall, I had considered setting up multiple instances of Klipper on a single machine. I ultimately went with a dedicated SBC for each printer, though, mainly for resilency, but also because I dreaded writing the udev rules for the can interfaces.
Nary a month on the heels of my writing about the Radxa Zero 2 Pro, I'm delighted to report I've received the Radxa Zero 3w. Setup couldn't have been easier—in just over a week, I managed to find and install an operating system.
The week before last, I won the sbc lottery. I happened onto the allnet website during the brief moment when the Radxa Zero 2 Pro was available. I ordered 2. They arrived in record time, exceeding their estimated delivery by half a week.
