- 13.33.32 Brandano | brb, I need to rebooth this machine
- 13.33.43 <-- | Brandano (~Brandano@pdpc/supporter/professional/brandano) has quit (Quit: brb) 13.33.45 Gragagrogog | did anything changed with TVs having terrible input lag even in "gaming" mode?
- 13.33.45 jammi | it'd also be neat to do things like respond to the tv remote volume buttons on the amp, since the connection is optical digital and the tv has no volume control authority over the amp
- 13.34.10 jammi | kinda sucks to have a lot of remotes, but most of the universal ones suck as well
- 13.34.26 jammi | and since cec is supposedly a solution for that as well, it'd be neat to use it
- 13.35.11 jammi | Gragagrogog: dunno, I don't think my existing one lags any more than the old one, which didn't support any fanciness and was basically a hdmi monitor in my use
- 13.35.45 jammi | meaning, I haven't really noticed any lagginess 13.36.10 jammi | however, I skipped several generations of tv's in-between
- 13.36.57 jammi | basically from first gen 1080p with hdmi to current
- 13.38.33 jammi | 4k res and especially the deeper "hdr" color modes was the main incentive to upgrade, plus the old one's backlight didn't light up every time (and I replaced every cap on it)
- 13.39.23 Gragagrogog | i didn't look into TVs for a few years, i currently own none, when i last checked a few they all has android-ish interface, slow as fuck input switching and a slight lag even in gaming mode...
- 13.40.48 <-- | teepee (~teepee@unaffiliated/teepee) has quit (Ping timeout: 272 seconds)
- 13.41.22 jammi | input switching on all devices seem to take at least a second, including monitors
- 13.41.33 jammi | probably a lot of handshake bullshit going on there
- 13.41.53 Gragagrogog | i'm talking ~10s plus
- 13.42.02 <-- | Andy-D_ (~Andy-D@188.28.24.231.threembb.co.uk) has quit (Quit: Alive/Dead)
- 13.42.03 jammi | and yet the display devices don't appear to be powerful enough to buffer them all and then just switch internally the output
- 13.42.29 jammi | or the manufacturers just chose to save a penny there
- 13.42.46 Gragagrogog | there are KVM systems which can do it faster but that's kinda pricey solution
- 13.42.57 <-- | stellarmind (~user@118.189.32.149) has quit (Ping timeout: 240 seconds)
- 13.43.20 jammi | my old tv had just two hdmi ports, so I used an external hdmi switcher (that had optical breakout as well, since that was lacking on the old tv as well)
- 13.43.34 jammi | a chinese one, was maybe 20€ or so and 4 ports
- 13.43.54 jammi | worked very well, and still works, but I haven't hooked it up
- 13.45.00 jammi | also allowed to pass audio out when the tv was off, which is another thing that's clumsy to do with the current setup (there's support for turning the screen off and keeping the tv otherwise on, but it's buried behind several levels of menus)
- 13.46.04 <-- | morbo (~morbo@5.146.250.80) has quit
- 13.46.07 --> | teepee (~teepee@unaffiliated/teepee) has joined #reprap
- 13.46.37 jammi | lg, webos 3.5 on this one. I'd rather have had a panasonic without all the multimedia bullshit builtin, but there were no resellers and they're large and heavy enough devices that shipping from other countries wouldn't be feasible

- 14.03.47 axi_ | Half way through printing a box. On the first layer, the corners are curling away from the bed just a hair. Thoughts? Printing PLA @200C on a heated bed @50C with masking tape. Room ambient is around 23C.
- 14.04.14 <-- | Ovion|MTW (isis.world@cpc87253-nfds16-2-0-cust191.8-2.cable.virginm.net) has quit (Ping timeout: 272 seconds)
- 14.04.14 jammi | hairspray, or less infill
- 14.04.41 jammi | and add brims as well if you don't have any
- 14.05.15 * | axi_ is tired and/or stupid.
- 14.05.17 axi_ | Brims?
- 14.05.19 jammi | the denser the large part is, the higher the contraction force it has when it shrinks (leading to curling), which is why less infill might help
- 14.05.30 axi_ | AH gotcha makes sense
- 14.06.11 axi_ | You'd think an engineer would have a basic understanding of thermodynamics :c
- 14.07.02 jammi | better bonding with the bed helps to some degree as well, hence something like acrylate hairspray on glass works really well
- 14.07.36 --> | Ovion|MTW (isis.world@cpc87253-nfds16-2-0-cust191.8-2.cable.virginm.net) has joined #reprap
- 14.07.37 jammi | but also provides the hairspray layer to break away from the glass
- 14.08.23 fakenullie | hairspray is more useful for abs
- 14.08.25 jammi | preventing stuff from sticking so well that they're unremovable without breaking the glass once they're printed, even when cooled down
- 14.08.31 fakenullie | I think glue stick works better for pla
- 14.08.55 jammi | fakenullie: works well enough and imho better, and much less of a mess
- 14.09.12 fakenullie | axi_: do you have heater bead?
- 14.09.14 <-- | webshinra (~webshinra@2a01:e35:8baf:4740:d54a:6df2:e3d8:1843) has quit (Remote host closed the connection)
- 14.09.15 fakenullie | bed
- 14.09.15 jammi | and if you apply it to clean glass, you get a really smooth and beautiful bottom layer
- 14.09.27 --> | webshinra (~webshinra@2a01:e35:8baf:4740:d54a:6df2:e3d8:1843) has joined #reprap
- 14.09.36 jammi | fakenullie: clearly, since he's set it at 50°C
- 14.09.39 fakenullie | axi_: I'd try 60 or 70C
- 14.09.55 axi_ | Right. I figured with the lower ambient, warming the bed a bit might help
- 14.10.07 axi_ | But yeah I need to get a glass plate for the bed
- 14.10.14 fakenullie | I think I've printed pla on 80C
- 14.10.16 axi_ | Only have an aluminum heated bed for now
- 14.10.24 fakenullie | oh, aluminum
- 14.10.35 fakenullie | cut a glass
- 14.10.36 <-- | arij (uid225068@gateway/web/irccloud.com/x-awqpfvgsgopttepd) has quit (Quit: Connection closed for inactivity)
- 14.10.40 fakenullie | or use ikea mirror
- 14.10.50 jammi | when you get the glass, turn the alu side to the bottom, and add some insulation
- 14.10.51 axi_ | But with masking tape this time. I'm going to get glass and hairspray/gluestick
- 14.10.56 axi_ | Gotcha
- 14.11.06 axi_ | Thank you guys for the advice :)
- 14.11.13 <-- | Affen (~Affen@dsl-hkibng21-54f87f-26.dhcp.inet.fi) has quit (Ping timeout: 248 seconds)
- 14.11.13 jammi | and use some silicone pads between the pcb and glass
- 14.11.34 jammi | like ones for to220 packages if you don't have anything else available
- 14.11.49 fakenullie | I've never used silicon pads
- 14.12.01 jammi | also, corner clamps for the glass rather than something that clamps it down
- 14.12.16 <-- | Ovion|MTW (isis.world@cpc87253-nfds16-2-0-cust191.8-2.cable.virginm.net) has quit (Ping timeout: 260 seconds)
- 14.12.40 jammi | the latter may deform it and may not keep it in place well enough

- 14.15.11 jammi | btw; any thermistor calibration tips? I spent yesterday getting marlin configured and patched (replaced an old repetier on the melzi), and calibrating my thermistors against a known good thermocouple
- 14.15.54 jammi | I got it spot on basically as far as thermistor vs thermocouple readings go, but when measuring actual inside-the-nozzle temps, readings are way off
- 14.16.11 jammi | like, up to 10-15°C
- 14.16.54 jammi | although it got better, like to the nearest 3°C or so after adding insulation on the hotend near the nozzle and thermistor
- 14.17.28 fakenullie | could be control loop issues
- 14.17.45 fakenullie | pid tuning
- 14.17.47 jammi | no, just the nature of thermal conductivity and radiation
- 14.18.00 --> | Brandano (~Brandano@pdpc/supporter/professional/brandano) has joined #reprap
- 14.18.01 jammi | ran pid tuning after every change in the setup
- 14.18.05 jammi | like always
- 14.18.37 Brandano | back
- 14.18.59 Brandano | jammi: I wish it actually worked, tbh. Does your printer have an enclosure?
