01:29 AM Jartza: http://www.microchip.com/wwwproducts/en/ATMEGA3209
01:33 AM Haohmaru: meh
01:50 AM nux_: CCL ?
01:51 AM nux_ is now known as nuxil
01:51 AM nuxil: how does CCL work?
01:52 AM nuxil: * Configurable Custom Logic (CCL) , refering to that on the Atmega3209 chip.
01:53 AM Haohmaru: that smells like microchip
01:53 AM Haohmaru: or am i mistaken
01:54 AM nuxil: does it mean we can move pins around?
01:54 AM Haohmaru: sorta like, you could pick a USART TX and a PWM timer thing, and tell the chip to logically AND them together
01:54 AM Haohmaru: iirc
01:55 AM Haohmaru: i could be mixing things up tho
01:57 AM nuxil: aha
01:58 AM nuxil: hackaday to the rescue
01:58 AM nuxil: https://hackaday.io/project/134831-atmega4809-developing-board-project/log/144552-how-to-start-configurable-custom-logic-on-atmega4809
01:58 AM nuxil: :)
03:19 AM Haohmaru: i just tried the USART at 1MHz noice
03:21 AM Haohmaru: sending 516 byte packets in 200ms period, seems nothing broke \o/
04:11 AM Emil: Haohmaru: you might want to include error correction and or detection
04:12 AM Emil: also
04:12 AM Haohmaru: i'm using synchronous usart here
04:12 AM Emil: 516 bytes at 1MBaud should go out at a lot faster than 200ms
04:12 AM Haohmaru: yes, they go out uber fast
04:13 AM Haohmaru: thing is, i'm generating them from a mirc script, sending them via tcp..
04:13 AM Emil: a bit over 5ms
04:13 AM Haohmaru: then that goes thru w5500+xmega (spi @ 4MHz), then the usart to the other xmega
04:14 AM Emil: wot
04:14 AM Emil: thats some topology you have there :D
04:14 AM Haohmaru: the small xmega deals entirely with the ethernet/w5500
04:15 AM Haohmaru: so it acts as a transparent tcp<->usart pipe
04:15 AM Emil: ah
04:15 AM Haohmaru: the big xmega is the usart master
04:16 AM Haohmaru: btw, my mIRC script begins to break at fast speeds before the xmega ;P~
04:16 AM Haohmaru: coz i print fancy visualizations of the data being sent, which consumes time and suffers from mIRC string length limits ;P~
04:17 AM Haohmaru: i also parse the communication protocol with it (in order to visualize it)
04:18 AM Haohmaru: ~1300 lines of fugly script
04:35 AM Haohmaru: oooh
04:35 AM Haohmaru: "When running CRC-32 and appending the checksum at the end of the packet (as little indian), the final checksum should be 0x2144df1c, and not zero."
04:35 AM Haohmaru: >:)
04:35 AM Haohmaru: beware of little indians in the datasheet
09:29 AM MrFahrenheit: nuxil, got my printer, assembled it, wired it up... z axis doesn't move
09:29 AM MrFahrenheit: awesome
09:30 AM nuxil: ouch.. that sucks
09:30 AM nuxil: sure you assembeled it correctly?
09:33 AM MrFahrenheit: yes, the motor works, swapping the x and z cables makes z move, so the controller is either broken or something isn't connected
09:38 AM MrFahrenheit: well that was easy to diagnose
09:38 AM MrFahrenheit: z connector just flapping around in the breeze
09:39 AM MrFahrenheit: should have opened the box before assembling it
09:39 AM MrFahrenheit: nuxil ^
09:40 AM nuxil: :D
09:41 AM MrFahrenheit: for a moment I thought it might have been my fault because I slowly moved the z axis by one turn while the control box was on
09:46 AM MrFahrenheit: https://www.dropbox.com/s/ht1bmh6gdidt0jg/2018-05-03%2016.40.42.jpg?dl=0
11:41 AM MrFahrenheit: nuxil, I'm printing a calibration cube
11:49 AM nuxil: MrFahrenheit, nice.. your 1st print ?
11:49 AM nuxil: are you printing with pla?
11:51 AM * nuxil hopes its not a 10x10 CM cube MrFahrenheit is printing :p
11:51 AM MrFahrenheit: well, second, the first one failed after 2 minutes :P
11:51 AM MrFahrenheit: yes, the pla that came with the printer
11:57 AM nuxil: my 1st calibration print looked like the leaning tower of pisa :)
12:01 PM MrFahrenheit: here, my first, second and third print: https://www.dropbox.com/s/wuw7405x64ykszk/2018-05-03%2018.57.50.jpg?dl=0
12:02 PM MrFahrenheit: (first one was me extracting the manufacturer pla out of the nozzle :P )
12:04 PM nuxil: you will find alot of stuff you cab print on https://www.thingiverse.com/
12:08 PM MrFahrenheit: so the cube is too large, what settings do I change in cura?
12:09 PM nuxil: i use repetier. how much too large is it ?
12:09 PM MrFahrenheit: 21mm instead of 20
12:09 PM nuxil: oh. thats alot
12:18 PM MrFahrenheit: it's consistently too large on all sides
12:20 PM nuxil: what is set as shell thickness & top/bottom?
12:20 PM nuxil: correct filament size set ?
12:21 PM MrFahrenheit: 0.8 and yes
12:22 PM MrFahrenheit: I'll try slic3r in a vm later just to see if its due to cura
12:22 PM nuxil: https://gyazo.com/777d8811de550bcefe33cb9befa9d29b
12:24 PM MrFahrenheit: oh neat, it supports irc too :P
12:25 PM nuxil: :p
01:06 PM nuxil: MrFahrenheit, if you just do a "cr10 mini" serach on thingiverse i bet you find tonz of mods and impovements for your printer.
01:07 PM nuxil: one thing i would suggest is guy wires or something like https://www.thingiverse.com/thing:2850557
01:08 PM nuxil: pimp your printer :p
01:19 PM MrFahrenheit: gonna do a fan upgrade at some point, I think, there's a "petsfang" mod
01:26 PM nuxil: yes. print a layer fan
01:26 PM nuxil: oh it has one
01:40 PM MrFahrenheit: printing a benchy now, it's pretty loud with the two fans
01:44 PM MrFahrenheit: 4 if you consider the control box
01:50 PM nuxil: yea
01:50 PM nuxil: thats why i made a box for my printer to put the psu and the controll board in.
01:51 PM nuxil: and so that the nozzle fan only runs as when the heater is on.
01:52 PM nuxil: the layerfan is controlled with software/gcode
02:05 PM MrFahrenheit: the nozzle fan is always on for some reason, the pcb has a free "fan1" connector though, so maybe it could be connected there
02:21 PM MrFahrenheit: nuxil, why is the nozzle fan even needed in operation - I mean, it's cooling the heater, seems counterproductive
02:29 PM nuxil: to prevent overheating the element
03:22 PM MrFahrenheit: aw, boat detached :(
03:22 PM nuxil: what are you printing on ?
03:22 PM nuxil: glass?
03:23 PM MrFahrenheit: yellow tape
03:23 PM nuxil: eww
03:23 PM nuxil: :p
03:23 PM MrFahrenheit: came with the printer
03:23 PM nuxil: get a glass plate
03:23 PM MrFahrenheit: the tape is on glass
03:23 PM nuxil: umm.
03:23 PM nuxil: why dont you print directly on the glass?
03:24 PM MrFahrenheit: cause the first print detached after 2 minutes on glass alone
03:24 PM nuxil: clean the surface with pure alcohole .
03:24 PM nuxil: before printing
03:24 PM MrFahrenheit: unless I need to spray some glue on it?
03:24 PM nuxil: not with pla
03:25 PM nuxil: what temp are you printing with?
03:25 PM nuxil: also you might want to add in a brim if the model detaches all the time.
03:25 PM MrFahrenheit: 195 nozzle, 60 bed
03:26 PM nuxil: up the temp to 205, the bed is ok. maybe a bit high for pla but should be well in limits. i only use 50 deg on the bed
03:27 PM nuxil: and make sure you dont go mess around on the bed with your greezy fingers.
03:27 PM MrFahrenheit: how dare you
03:27 PM nuxil: :D
03:28 PM MrFahrenheit: I only ate a tuna sandwich with olive oil and mayo
03:28 PM nuxil: :)
03:31 PM MrFahrenheit: on the plus side, the benchy turned out real good, there are visible infill lines on the hull but they're not actually surface artefacts as I thought
03:31 PM MrFahrenheit: seems just that this pla is a bit translucent so the infill is visible through it
03:32 PM nuxil: also. the filament you got with the printer may be crap. i read that some got crap filament with the tarantula. while others got good. i had no issues with it to.
03:36 PM MrFahrenheit: you just use plain glass?
03:37 PM MrFahrenheit: no glues?
03:37 PM nuxil: plain clean glass
03:37 PM nuxil: so.. here is design for your 1st mod. https://gyazo.com/51fb04725f6b454ebd67e45a1c63e052 change it for your printer :p maybe add a sense line for both bed and nozzle
03:37 PM nuxil: source code for you to modify https://pastebin.com/CgR3ds0j :D
03:39 PM MrFahrenheit: I was literally just telling someone how I never get to use an attiny13 for anything
03:40 PM nuxil: lol :D
03:40 PM nuxil: yea
03:40 PM MrFahrenheit: looks like an attiny10 would work here too though
03:41 PM nuxil: its a simple circuit and code so i see why not.
03:42 PM nuxil: but doing timeing on these chips kindof sucks due to the +-20% tolerance. but its not a time critical thingy so it will work.
03:47 PM nuxil: MrFahrenheit, do you need to level the bed manually or does it have a touch senor?
03:48 PM MrFahrenheit: manual
03:48 PM nuxil: ok
03:48 PM MrFahrenheit: there's a mod you can buy with the sensor and firmware and stuff made by th3d
03:48 PM MrFahrenheit: $50 or something
03:49 PM theBear: manual ? ke ? i'm so sorry, i'm from barcelona ! <silly grin>
03:49 PM MrFahrenheit: jajajaja
03:51 PM MrFahrenheit: nuxil, did you get your new filaments?
03:51 PM nuxil: yes i have alot now.. almost 1km with filament :p
03:52 PM MrFahrenheit: I think I used 2m today :P
03:52 PM MrFahrenheit: what colour do you like most?
03:54 PM nuxil: i have red, dark blue, light blue, black, white and "transparant". i like the black and the dark blue one.
04:56 PM MrFahrenheit: btw. nuxil, the cube is actually correct, I was misreading my dial calipers because the digits are to the left of the line they belong to
04:56 PM MrFahrenheit: haven't used them much before now
05:02 PM nuxil: hehe. noob :p
05:02 PM nuxil: MrFahrenheit, your printer does it have a 0.2 or 0.4 nozzle ?
05:09 PM MrFahrenheit: 0.4
05:11 PM nuxil: oki. im thinking about ordering a 0.2 nozzle for fine prints.
05:15 PM MrFahrenheit: cool
05:16 PM MrFahrenheit: oh, what base do you use for your prints, cura has a few options, I just used skirt
05:19 PM nuxil: depends on the model.
05:19 PM nuxil: but i often use brim
05:20 PM nuxil: repetier has the option. brim and raft
05:20 PM nuxil: i dont like raft
05:22 PM nuxil: i also often dont use a base
05:41 PM nuxil: MrFahrenheit, https://www.simplify3d.com/support/print-quality-troubleshooting
05:45 PM MrFahrenheit: useful
05:45 PM nuxil: it is
11:27 PM day__ is now known as day
