    Aug 1, 2018 at 6:15 PM - daniel871: Anybody know where I can get an easy to use filament EEPROM reset for DaVinci printers?
    Aug 1, 2018 at 6:16 PM - daniel871: I won a 2.0A for $200 on a random ebay auction I bid on a month ago and forgot to watch.
    Aug 1, 2018 at 6:18 PM - daniel871: "Won". It is a new-in-box machine, but I'm not crazy about trying to flash Repetier to the control board because that requires jury-rigging a jumper between two unsoldered pin holes while powering the machine up to allow firmware writing.
    Aug 1, 2018 at 6:18 PM - daniel871: I'd rather "hack" the catridges.
    Aug 1, 2018 at 6:20 PM - daniel871: But all of the first page Google results point to a web store selling dummy-configured cartridge reset units that is out of stock.

    Aug 2, 2018 at 10:15 AM - NFOsec: What's up wenches?
    Aug 2, 2018 at 10:28 AM - daniel871: Troubleshooting a hilarious DaVinci printer.
    Aug 2, 2018 at 10:28 AM - daniel871: "It came from Ebay" basically.
    Aug 2, 2018 at 10:29 AM - daniel871: I like the build itself, but the Y-axis isn't functioning properly so I'm trying to figure out what the issue is.
    Aug 2, 2018 at 11:19 AM - daniel871: Okay, that problem solved.
    Aug 2, 2018 at 11:20 AM - daniel871: Turned out pretty much every single screw in the frame had loosened during shipment and the tensioners were fully extended. Went around tightening frame screws and adjusted the tensioners, printer homed successfully.
    Aug 2, 2018 at 11:20 AM - daniel871: Ran calibration for the heaters and Extruder #1's heater is dead. :(
    Aug 2, 2018 at 11:20 AM - daniel871: Extruder #2's heater works and the bed heater works.
    Aug 2, 2018 at 11:21 AM - daniel871: Now to figure out how to get it to read/run files in XYZware that are sliced for extruder #2 only.

    Aug 3, 2018 5:40 AM - daniel871: Welp, the printer seems to work, for some values of work, now to just figure out how to reliably send programs to it/get a Raspberry Pi/Octoprint set up to feed it and make it my ABS printer.
    Aug 3, 2018 5:52 AM - Geof: Daniel is this an XYZ ???
    Aug 3, 2018 5:52 AM - Geof: curiosity has the best of me, what did you pay for it? Always seemed like a stout printer with short comings in firmware/closed source spool system
    Aug 3, 2018 6:30 AM - daniel871: $200.
    Aug 3, 2018 6:31 AM - daniel871: Turns out if you use the "secondary" hotend as the primary hotend that the firmware doesn't track the filament used and as long as you have a cartridge in the slot, you can bypass it and feed open-source filament through the tube to the hotend.
    Aug 3, 2018 6:31 AM - daniel871: I don't really give a shit about dual-head printing, so that seems like an easy bug to exploit to do what I want. It also works with Simplify3d so.
    Aug 3, 2018 6:32 AM - daniel871: I'll play with the printer some more next week at home and see what kind of print quality I actually get.
    Aug 3, 2018 6:33 AM - daniel871: Interesting tidbit, the printer uses what appears to be bronze sleeve bearings on the rods instead of LM*UU style ball bearings.
    Aug 3, 2018 6:34 AM - Geof: I remember them being kind of loud. This must be a newer one?
    Aug 3, 2018 6:34 AM - daniel871: So instead of that rolling-bb noise you get that quiet hissing sound. Loudest noise is the stepper motor but even that isn't that bad. Sounds like an inkjet printer running around.
    Aug 3, 2018 6:35 AM - daniel871: I should probably look at around on the internals of the machine for a manufactured date.
    Aug 3, 2018 6:36 AM - daniel871: Not sure on when they put it out originally, but the older ones had transparent gray side panels, this one has transparent blue panels.
    Aug 3, 2018 6:38 AM - daniel871: It's a bit odd on the build area. 7.9" on Y, 5.9" on X, 7.9" on Z.
    Aug 3, 2018 6:38 AM - daniel871: Probably because they slapped that second extruder/hotend in there.
    Aug 3, 2018 6:39 AM - daniel871: They claim 12.5 micron X/Y positioning precision at non-printing traverse speeds, so that'll be interesting to push with the printing speeds.
    Aug 3, 2018 6:55 AM - Geof: thats pretty hard to believe honestly lol. but its possible! Wonder if it gets that due to a compensation in their slicer that using S3D you wont see?
    Aug 3, 2018 7:00 AM - daniel871: Not sure. The entire motion system is pretty rigidly constrained with how the belts/tensioners are set up and how the belts are tied into the axis carriages.
    Aug 3, 2018 7:01 AM - daniel871: The belts themselves look to have fiber reinforcement in them as well.
    Aug 3, 2018 7:02 AM - daniel871: But I'm not familiar enough with belt-driven motion systems to know if that's a good thing over time or not.
    Aug 3, 2018 7:15 AM - Geof: reinforced belts are a good thing. They dont rubber band on you.
    Aug 3, 2018 7:43 AM - daniel871: Welp. Assuming I get it home in one piece this machine may be a pretty good deal.
    Aug 3, 2018 7:47 AM - Geof: I'd say so. 200 is pretty fair for any used machine. Odd bed size for sure but having the length in one axis makes up for it IMO.
    Aug 3, 2018 7:50 AM - daniel871: Finally have a machine where the bed is stationary except for the Z-axis movement.
    Aug 3, 2018 8:01 AM - Geof: yep I am actually a pretty big fan of them as of lately. You get rid of the noise in your print from the heavy bed moving back and forth.
    Aug 3, 2018 8:11 AM - Geof: I think the far over hyped MK2 was the last of that style machine I've bought (not impressed). Since then its been all replacements for moving bed set ups.
    Aug 3, 2018 8:20 AM - daniel871: The only thing I didn't like about my experimenting so far with the Davinci is that it refuses to initiate a print unless it detects a cartridge in both cartridge slots and filament present in both hotends, regardless of whether the hotend is going to be used at all during a print.
    Aug 3, 2018 8:20 AM - daniel871: I mean, I get it because it's probably super-simple to code that check, but still.
    Aug 3, 2018 8:40 AM - Geof: yea they were big on making you buy their carts if I recall. The library had one I helped them with a long time ago. Pain in the butt lol.
    Aug 3, 2018 8:41 AM - Geof: the real kicker of it was if it jammed it still counted it as "used filament" because the printer didn't have a monitoring system. They did a large print once and had a ton of filament left, but the machine said cart was empty so they had to get a new one. Suck city.
    Aug 3, 2018 8:41 AM - Geof: glad that one has long since been door stop lol
    Aug 3, 2018 9:17 AM - daniel871: If it's still around and had the dual extruder setup, that bug where you can use the "second" extruder to extrude and it not actually count the filament might be useful.
    Aug 3, 2018 10:26 AM - Geof: nah to many good machines lol. I gave them a decent machine, cant even recall what it is. I think it sits in the back room now. To much frustration for them
    Aug 3, 2018 11:07 AM - daniel871: A lot of people hack them to use Repetier firmware and then supposedly have much better machines because the actual build quality is good, it's just semi-crippled convenience-wise by the half-ass attempt at closed sourcing it.
    Aug 3, 2018 11:16 AM - Geof: ah gotya. yea that would make more sense. They are build like tanks for sure.
    Aug 3, 2018 11:27 AM - daniel871: I only mention it to put the idea of a reasonable salvage printer in your head.
    Aug 3, 2018 11:27 AM - daniel871: Go over it to tighten everything up, open-source the firmware on it, turn it into a tank of a printer and either put it into production or set the library up properly with it.
    Aug 3, 2018 11:31 AM - Geof: nah more time than I have to invest these days my friend. I barely have time to get on here and help out anymore lol. shoutbox is about all the more I can get to
    Aug 3, 2018 11:31 AM - Geof: running all the machines is an all day job lol
    Aug 3, 2018 11:52 AM - daniel871: https://i.imgur.com/yybVgEs.gif
    Aug 3, 2018 11:59 AM - Geof: lmao
