AFAIK, The Techzone Monolithic board is simply their version of the Gen 6 boards, and so should probably operate in a similar way, although i'm not sure how the Gen6 handles the tip - TZ has a tip conversion Does that answer your question?by EtherDais - General Mendel Topics
I put my opto endstops on the y-bar clamps, and attach flags underneath the bed to trip them, so I probably won't have any feedback as far as using that piece for the opto. I was only going to use that for the belt. The M8 nuts aren't really there for any particular reason, I may remove them later. If wobble from that piece is an issue in the future, they'll be nice to have there. Buback,by EtherDais - General Mendel Topics
Got the OpenY assembled this afternoon. I had to use a slightly shorter rod (~125mm), but it was threaded 8mm, and i'm not sure it was willing to go all the way into the mounts for it. Then again, I was aligning it to the print bed that TechZone supplies, and i'm not sure it has the same hole placement as you were designing for. The 6-bearing 'snap-on' side is looking sharp, i'm still tweakingby EtherDais - General Mendel Topics
The tip adapter is strange. In October when I got my LC mendel from Techzone there wasn't a tip adapter at all. The teflon tube extending from the oak block was butting up against the filament exit hole on the extruder, and there wasn't an obvious way to mount the tip properly. After I got another tip kit from them, they threw in the tip adapter and it all fell in place for me: I mounted it vby EtherDais - General Mendel Topics
As far as the TZ Huxley goes, our main issues have been shortages on the included components (Hey, bean counting can be a beast). Double check your inventory, we are concerned that their packing list may have the number of bearings misabled. Feel free to PM me. We are collecting images and video for updating the wiki build instructions, and I believe some small updates have been made alreadby EtherDais - General Mendel Topics
Thanks for that. Another request: If you happen to get an estimate of the BOM (screw lengths etc.) It would be much appreciated. Just printed out openX this morning, and I'm doing openY now. I think I can follow your images to get the X carriage but I've not visualized the Y yet. I won't have electronics to run this system for another week or so but once that happens I expect to be giviby EtherDais - General Mendel Topics
Rista, As Nutz4hs mentioned, we are building two TechZone Mendels and one TZ Huxley for an Engineering Design course here at Penn State. The documentation for both of these units is still sloppy, but we are hoping to collate all the relevant wiki pages here in the process of reviewing the current material. Currently the relevant information is strewn over several wiki pages. Please do not hesby EtherDais - General Mendel Topics
Hi Buback, Really enjoying your OpenX design. I'm just building my first 'non-strapped' mendel, and I'm thinking about running with your open axes entirely. The only pressing dimension i was wondering about was the length of the 8mm rod on your OpenY. I assume you need this to be specific so that the holes line up with the print bed holes. I think this is the really pressing parameter as faby EtherDais - General Mendel Topics
There's an alternative way to mount the TechZone tip that seems to be poorly documented, but very stable: Step 1: Screw the 'tip adapter' piece into the wooden block, using two screws which pass through the thin edges around the teflon insert. Step 2: Use the mounting holes on wade's extruder to pass screws through the tip adapter. If the screws in step 1 were placed correctly, these secoby EtherDais - General Mendel Topics
Without going into elaborate detail, I wanted to post here that there is now an effort to develop multiple rep-raps around University Park campus. Check out what we're up to here: If anyone would like more information please contact dbs198 at psu dot edu.by EtherDais - Pennsylvania RepRap User Group
I've been working on my TechZone LC Mendel for the last few weeks. We seemed almost ready to start print testing this saturday: The mechanical systems were all functioning properly, and the extruder motor was running using only the standard Mendel firmware to drive it. All hell (smoke and fireworks show) broke loose when we tried to run the system after loading the techzone firmware modificby EtherDais - General Mendel Topics
