who? press post navigation ← older posts case prototypes in cardboard posted on august 14, 2018 by sandy reply one of the challenging and exciting parts about polargraph is trying to avoid changing things while still progressing the project. changing things is easy enough when it comes to code (though requires re-testing), but it gets harder and more expensive (and much slower) when it’s a physical item, like the pcb or the case. the last case was lasercut acrylic. this new one will be too, but i don’t have a laser cutter nearby, so i prototype in cardboard. this is just the shapes printed out and stuck to the a sheet of corrugated cardboard, and cut out with a scalpel. there’s limits to what degree of realism i can achieve with this low-fidelity mockup, but i can test the major interactions. i discovered i’d completely forgotten to put a set of tabs in on the end plates. other than that, a bit of misalignment here and there. the files are off to the laser cutter! in other news, i have had some good results with the new firmware (https://github.com/euphy/polargraph_server_polarshield_esp32) which has got high stepping rates, along with good responsiveness from the screen. happy with it so far… but i haven’t tested it properly yet! eeek! posted in machine | leave a reply polarshield v3.0 posted on may 13, 2018 by sandy 1 the new polarshield v3.0 is a refreshed version of the core polargraph hardware. it has been re-designed from scratch and snips out a few of the snaggles that the old machine had. it allows integration of: espressif esp-32 based microcontroller 2x a3988 stepper drivers lcd and touchscreen sd card for stored command queues servo for a pen lift so the only real difference is the controller, which is a fast, 32-bit, dual-core device, with a real-time operating system (rtos), oodles of memory and built in bluetooth and wifi features. there is a working arduino-based toolchain for this esp-32 device, but it also has the horsepower and memory to run micropython. i’ve ported the standard polargraph_server_polarshield code to target this platform (in a branch – https://github.com/euphy/polargraph_server_polarshield/tree/esp32) and it works great … in principle. there’s a couple of bits don’t work yet, and i haven’t done any long drawings with it. on the polarshield itself, the hardware design is simplified because the esp-32 is a 3.3v device and so are the stepper drivers, touchscreen and sd card, so there’s no need for level shifting. the lcds are of a more modern and widely supported design too, so i expect to have fewer problems with them. there are spare pins i’ve broken out for: 2x motor shaft encoders for close-loop positioning end stops for automatic calibration i haven’t yet implemented any features around the encoders, endstops, wifi or bluetooth, and might never do that. why the change? the polarshield v2 has never been a reliable build. the straw that broke the camel’s back was earlier this year when i was building a batch and i ordered 20 boards, built them and only got six working polargraph machines out of them. the lcd that it uses is growing to be somewhat esoteric in that configuration, and so it’s hard to debug. it uses a kind of simulated spi which just isn’t reliable enough, or has too many odd interactions with other parts of the circuit. the new 5v step-down power supply is an economic choice. i’m using a little off-the-shelf mini-assembly with a mp2307 and an inductor on it, rather than building the supply right onto the board itself. amazingly, the little assembly is available to buy (ready-made) for less money than it costs me to buy a single mp2307 chip on it’s own . the esp-32 is a little cheaper than a good arduino mega-2560 clone. the current arduino toolchain is a bit of a dog to set up, but dedicated developers has done an amazing job porting libraries to it. it’s dead fast and has a good small footprint. mega-2560s are huge. natively running at 3.3v is a bonus and performance with spi-based touchscreens is phenomenal. what’s next this is a platform that could easily take us into polargraphpro territory, with encoders and endstops to make for a safe and reliable continuous drawing experience. the mcu is powerful and the wireless features are very tempting. however, i have no immediate plans to implement any new features and will focus on getting old ones ported and re-worked where necessary. i’ll probably take this opportunity to dump a few lesser-used features too. mailing list if you want to be alerted when these reach stock, or you’re interested in email updates about the project, you can sign up to my mailing list and choose what kind of things you want to hear about: polargraph mailing list (http://eepurl.com/dhvafp) posted in business , machine | 1 reply discovering drawing discovered polargraph posted on september 1, 2017 by sandy 3 i was proud and pleased to get a copy of the 3rd edition of discovering drawing by sallye mahan-cox through my letterbox. not because i need to discover drawing (that ship sailed a long time ago), but because your very own polargraph is featured as a “non-traditional approach”. isn’t that lovely? posted in uncategorized | 3 replies polargraph, back in action posted on april 9, 2017 by sandy 5 without much fanfare, i reopened for business last month! i had a waiting list, so gave those people first dibs before announcing it widely. but the first dozen machines are delivered now, and i’ve just listed the next ten in the usual place: http://polargraph.bigcartel.com/product/polargraph-sd-assembled-tested in an embarrassing twist, i accepted the challenge of making some videos to show what the machine is, and how it goes together. oh, er, there’s more of my gurning fizzgog: and just when you’d had enough … more: sorry about that. posted in business , uncategorized | 5 replies quality control is frustrating posted on march 23, 2017 by sandy 1 the eagle-eyed among us may have noticed things happening in polargraphland! i have listed some more machines for sale, and they’ll be shipping in the first half of april. http://polargraph.bigcartel.com/product/polargraph-sd-assembled-tested that’s good news! i’ve already mostly built most of a batch of 32 machines. one of the things i was pleased to get out the way quite early was printing the sprockets. i’d rebuilt my 3d printer since the last time i did it, so i had some tuning to do to get that perfect print. i didn’t want to do it because i hate the slow pain of trial and error. anyway, long story short, i got some settings that i was happy enough with and printed off around 80 sprockets – enough for this batch, plus some discards for quality control. well, i didn’t adjust the settings quite enough, because the holes in the middle are about 0.2mm too large. they get printed in batches of 16, and about two out of every batch was ok – and those were the two i tested. the rest of them were much too loose. it makes them a really easy push-fit onto the motor shaft … and i hoped they’d be good enough, but i was making a how-to video this week and running these new sprockets and got a real sinking feeling… they aren’t good enough. there’s enough play on the shaft that the hole will eventually round out, and it’s a case of when, rather than if, the sprocket loses it’s grip. even a dab of glue doesn’t solve it. so it’s time to go through all my partly-packed machines and lever the sprockets off, and also run the 3d printer for the next few days to print replacements. on one hand, it’s great that i’ve found this out, an
