I liked what I saw with +the Prusa Connect, as an alternative to my tested and tried [[Octoprint](https://octoprint.org)], +and particularly it's nice to be able to send objects directly from the Prusa Slicer UI to a device +queue, and mark the printer _ready_ once the finished parts are removed and the bed is clean. + +As it turns out, these features with PrusaLink are also available for the MK3! You can print a +different Einsy container which allows for a companion Raspberry Pi Zero to be attached to the board +using overly long (18mm) header pins. And it so happens that I have both the pins as well as a +Raspberry in my electronics box. + +Off i go, using the MK4S to print new parts for the MK3, and while I'm at it, I also see that +there's an upgrade path from MK3 to MK3S+, with a few new parts to be printed. And now I'm in the +rabbit hole, and I'm in deep, and I see that there's *also* a few new parts on the extruder for my +oldest MK2.5S printer. So I use the MK3 to print parts for the MK2.5S, while the MK4S printer makes +parts for the MK3S+. I feel like I'm in an _Inception_ movie ... Printers printing Printers, must go +deeper. + +Once the new board holder is printed, I solder the pins onto the Raspberry and flash it with the +Raspberry Pi imager and a stock Prusa image. I plug it in, and go off to lunch, as the instructions +say that the first install can take a while. When back from lunch, the printer is up and running, +connected to WiFi, and is asking me to associate it with Prusa Connect. That task takes no longer +than a minute, and I send my first object directly from the PrusaSlicer to this MK3 - slick! + +The rest of the day, the printers are doing 8h, 10h prints for all the replacement parts for the +MK3->MK3S+ and MK2.5S refurbishment. I may end up selling the MK2.5S, in case you're interested, let +me know and I'm sure we can work out a reasonable price for it! + +Now it's time for housekeeping. Marina and I divvy up the work in the bathrooms. I'll take the +ground floor and second floor attic, she'll take the first floor. We take care of the porcelain +thrones and wash basins and showers and what-not. Marina cleans the shower by .. taking a shower. A +rather novell technique, I must admit. + +One that is out of the way, Marina and I go shopping. We plan the rest of the week and weekend in +terms of evening meals; and try to make it diverse with fish, beef, tofu, potatoes, rice and pasta. +But Marina also needs to finish her home improvement project, to upgrade the plungers on our toilet +water reservoirs, a drama that keeps on giving: every time she makes an improvement, it turns out +there is still water leaking through once the reservoir is full She decides to get yet another part +to see if that helps; and while we're at _Jumbo_, I also get an extension with a water filter for +our basement faucet. + +At _Coop_, we end up keeping to our shopping list _roughly_, although we have a conversation about +an italian wine from _Vecchia Torre_ that I am pretty sure we have in our cellar, although Marina +disagrees. You get one guess only: who do you think was right? At the grocery store I'm reminded of +an old Googler buddy of mine - Pascal Bovet - who moved to New York a long time ago, but from time +to time I still cross paths with him on LinkedIn. His login name at Google was bopa@, and at our +local _Coop_ grocery store, they were doing some works, revealing this [[bopa.ch](https://bopa.ch/)] +branded concrete construction block. I pinged him on LinkedIn, hoping to solicit a smile. + +### The Stromer Jynx + +While we're at the _Coop_, an e-mail pops up on my phone: the Stromer is ready! So we finish our +business at _Coop_, drive home to unpack and put away the groceries, and I make the faucet look more +like a mosquitto (once you see it, it cannot be unseen). Then off to Stromvelo we go. When we're +close by, I ask Marina if maybe she could wait in the car until I manage to pay and retrieve the +bike. It's at this very moment that I think I jynxed it. + +The guy at Stromvelo is super, he walks me over the invoice (which is hefty, but then again this is +a Stromer ST5, so everything ie expected to be pricey). Theyv'e replaced the rear tire+innertube, +the +/- buttons on the handlebars, the torque sensor, as well as the front brake disc. All up, a +good service, but there is one problem. He turns on the bike and the dreaded "Cannot connect to +Torque Sensor" error pops up immediately. That's the same problem that I brought it in for in the +first place. He does a quick ride on it and comes back with bad news: problem is not fixed :-( + +The Stromvelo guy clearly feels bad, but I've already sent Marina home [duh!] so I ask for a loaner +bike. He prepares an St5 replacement for me, and I sign the paperwork for it. He tells me the PIN +code but when I try it, it doesn't work. So off he goes, to reset the PIN code, and eventually he +comes back outside and I think I have everything I need. Turns out, the battery has only 12km left +in it, and it's about 7km ride. I insist that I'll be fine, even though he offers to swap the +battery. + +I ask if maybe the bike can be done before the weekend, as I'll be off to Friesland next week. Alas, +even more bad news: Stromvelo Buchegg is off for a training course (German: _Weiterbildung_) on +Thursday and Friday. But, he says, he'll make it a life mission on Saturday to take a good look at the +bike and see what's up. He promsies to give me a call, and I have the replacement ST5 until then. +All in all, I'm grateful that Stromvelo made the best of an otherwise bad-luck-jynx situation. + +The bikeride home was uneventful, thank goodness. Back home, I 'made' dinner, which is to say I +yeeted some potato / rösti croquettes and a few _Schwyzer Güggeli_ (rotissery chickens) +into the oven and exercised patience for thirty minutes. + +After dinner, we watched a few episodes of _V Wars_ on Netflix, after which I went downstairs to +enjoy the smell of molten PLA and PETG, paired nicely with a dram of _Grappa Di Vinaccia_ from +distillery _Vergnano_. You know this stuff is serious when it ships in a one liter bottle. + +## Pictures of the Day + +{{< gallery-category >}} + {{< gallery-photo fn="2024-09-04/IMG_1119.JPG" caption="The new case for MK3S is printing - it'll contain a special cavity for a Raspberry Pi Zero which will hook up this printer to PrusaLink." >}} + {{< gallery-photo fn="2024-09-04/IMG_1120.JPG" caption="The finished parts for the new MK3 case on the MK4S printer." >}} + {{< gallery-photo fn="2024-09-04/IMG_1121.JPG" caption="The MK3 case is retrofitted, the Raspberry Pi is installed and the display helpfully shows 'PrusaLink' is being started." >}} + {{< gallery-photo fn="2024-09-04/IMG_1122.JPG" caption="I think of my buddy Pascal Bovet who goes by @bopa - he enjoys seeing the picture when I send him a DM on LinkedIn" >}} + {{< gallery-photo fn="2024-09-04/IMG_1124.JPG" caption="The Vecchia Torre that I could've sworn we have in the basement, but Marina says we do not.
