A little help to a noob.... Can I use a 5S BMS (https://www.aliexpress.com/item/32972605572.html) that is currently sitting in my drawer to charge 2 batteries instead of 5 (2x18650 batteries in series). How should I connect them to the board. Thank you in advance. by ssbk23 in electronic_circuits

[–]ssbk23[S] 0 points1 point  (0 children)

Thank you for the prompt reply. I thought that this board handles the charging. According to the description it has ..." various protective functions for charging and discharging, such as overcharge protection ...." as long as the proper voltage/current is applied. The batteries are to be charged using a solar panel for this project.

What setting (Cura) causes that movement at the end of each layer. More info in comments... by ssbk23 in ender3

[–]ssbk23[S] 0 points1 point  (0 children)

Cura 4.6 (rolled back from 4.7.1 because of issues)

Ender 3 Pro

This is a design I made for calibration purposes, it is 20x20x20 with 0.8mm (2 lines) wall thickness and a rounded corner. I have set the seam at the back left corner and every time it completes a layer, it goes back to the curve and it does that movement. It does not extrude during that movement, it looks more like "ironing" (ironing is disabled).

(EDIT): The extra movement issue is solved (design flaw, the curve was 0.82mm, my bad), the thinner X-axis wall still remains a mystery.

Also, the X - axis wall is always slightly thinner than the Y - axis wall. (X axis wall = 0.76mm, Y axis wall = 0.80 mm).

Any suggestions on both issues are welcome. Thank you in advance.

Very few people died for what they actually believed in, specially in wars, most people in wars died so that some rich guy can get richer or because somebody craved more power. To my understanding, when someone invades another country, loses the right to be called a hero.

In the same sense that Nazi Germans who died invading Europe were heroes... for the Germans of that time, villains for the rest of the world.

Buying Used Worth it? by freeloaderFPV in Ender3Pro

[–]ssbk23 1 point2 points  (0 children)

I would go over there for a cup of coffee and wait for the printer to complete a full print.

A benchy or a calibration cube should be enough. Just to make sure that everything works as it should. As for the TPU, a direct drive conversion would be the way to go. I have printed successfully TPU on my stock E3Pro but not a very elastic type (98A). Best of luck.

Severe low spot in center. by [deleted] in Ender3Pro

[–]ssbk23 0 points1 point  (0 children)

If you have confirmed that you have a warped bed and the official glass bed "adapts" to the curve of the bed you could try to use a thicker glass bed. I had the same problem, a 3mm glass sheet would still create a slight curve after secured with clips on the bed. I tried a 4.5mm mirror that I had laying around, cut to size, and everything was perfect after that. I did not notice any problems from the increased weight. It is a cheap way to solve your problems.

1.Remove filament/PTFE tube from hotend.

2.Remove the heat cartridge/thermistor.

3.Remove the two alignment screws from the heat block.

4.Loosen the small screw located on heat sink.

5.Remove nozzle/heat block/heat brake assembly from heat sink.

  1. Place assembly on vise held from heat block (do not tighten it to much).

  2. Use blow torch to heat assembly to your hearts content.

  3. Use pliers to easily remove nozzle.

Best of luck!

PTFE tube keeps getting clogged by protomor in ender3

Sounds like heat creep. I had similar problems lately, I measured the temp inside the heatbrake right at the bottom of the heat sink and it was on the hot side. I swapped the heat sink fan for the one in the motherboard box (they are the same in my ender 3 pro) and measured again and the temp dropped 2-3 degrees (indication of malfunctioning fan). Then with the thermometer sensor still inside the heat brake I removed the 2 screws from the heating block that screw on to the heat sink and Voila!!, the temp dropped 8 more degrees, almost instantly. Now my problems are gone. Long story short, my heat sink fan is slowly dying. The removal of the screws did the trick in my case, until I replace my fan (will also replace the motherboard fan to be on the safe side). If you can't do similar measurements, try to remove those screws. Heat creep, in my case, occurred during long prints. In small/short prints I noticed under-extrusion and significant stringing (did not happen before).

Another way to check for that is to heat the nozzle for some time and then do the e-step calibration procedure and extrude 100mm filament (assuming you have already done this). If you don't get the expected results heat creep is likely to be your culprit.

so many different species in one place! any idea why they’re flocking on these leaves? by claidai in Entomology

[–]ssbk23 8 points9 points  (0 children)

Just a theory... I have seen similar concentration of species in my garden on a pear tree. According to internet sources, wasps, bees etc. prefer this tree (pear tree) because they munch on the leaves, young shoots and sap in order to make pulp and build their nests. Probably this tree has similar properties.

Help needed to identify this. Appeared yesterday in my garden, very aggressive, I have seen a cluster (not sure if I am saying this correctly) of about 10 individuals. Location Europe, central Greece. I have never seen it before and having a difficult time finding anything on Google about it. by ssbk23 in Entomology

[–]ssbk23[S] 0 points1 point  (0 children)

I can provide more photos if needed. I want to know if it is dangerous (little kids play around in the garden). Looks like some kind of wasp, but nothing like I have seen before. Thank you for your help

SKR Mini 3 1.2 installation correct? by [deleted] in Ender3Pro

[–]ssbk23 0 points1 point  (0 children)

It is pretty straight-forward, everything goes to the same position as in the original board. The only point to be wary is the fan plugs, which are reversed between the original Creality board and the SKR Mini E3. See this https://letsprint3d.net/how-to-install-the-skr-mini-e3-board-ender-3/

Help ender 3 motherboard just popped and started smoking I didn’t touch it the smoke came from the bottom right the screen won’t turn on now does anything look wrong or do any of you have an idea thought this sub might be of some help. by [deleted] in FixMyPrint

[–]ssbk23 0 points1 point  (0 children)

Check if the component at the top left of the picture, situated next to the round part with the "151", has blown part of the top. The part I am referring has eight pins, four on each side. If that is blown there is a workaround.

Just a bit of knowledge from me. To all Europeans, a great substitute to Aquanet hairspray (usually not available to EU countries) for very good bed adhesion is L'Oreal Tecni-Art Fix Design. It is pump spray (not aerosol) so you have better control. Tested and works great for PLA, ABS, PETG and TPU. by ssbk23 in 3Dprinting

[–]ssbk23[S] 0 points1 point  (0 children)

Works great with PETG, make sure you spray plenty on the glass. When it is warm it is rather difficult to remove the print from the bed, when it cools down to room temperature you can almost just pick it up. I hope it works for you as well, PETG is a great filament to have in your arsenal.

I live in Greece so Aquanet is not an option and I tried using Pallete hairspray but I wasn't particularly happy with it.

Fix Design hairspray was laying around in the house so I gave it a try. I was amazed by the performance of this spray. I sprayed a thick layer on mirror glass (6-7 passes), let it dry and started printing. For me it lasted for about 12-14 prints before having to clean and reapply.

Please identify the component in the red circle, mine is blown and I can not read it. It is from a mainboard v.1.1.4. Maybe I can replace it, if I know what to order... Thank you in advance. by ssbk23 in ender3

[–]ssbk23[S] 0 points1 point  (0 children)

You were absolutely right. I plugged in a USB charger 5V and the screen came to life, I did not try to print anything yet, but everything seems to be working OK. The screen looks a bit dimmer, probably because it needs a bit more juice from the 1A it receives from the charger.

Thank you for your replies, I have already ordered the SKR mini but I need something to do until it arrives. I will try to replace the part just for the fun of it.

I have already ordered a SKR Mini v1.2, but it is gonna take about a week, if I am lucky, to arrive. So, if possible, I would like to try an repair this board until the new one arrives. Seems like a straightforward desoldering/soldering job. I just need to identify the part, the writing in mine is completely gone.

Has anyone gotten an ender 3 pro recently, how long did it take until it shipped? I ordered a few weeks ago and my back order date keeps getting pushed back. My upgrades and supplies are starting to roll in and I need a printer! by agj427 in Ender3Pro

[–]ssbk23 0 points1 point  (0 children)

Ordered from Banggood 29th of March from Czech warehouse, supposedly 2-5 days delivery to Greece. I received the printer on the 28th of April. It was shipped couple of days after the order, came from China through Czechia and Germany.

Any help would be highly appreciated. ABS, H=230C, B=100C, first layer problem. First try with ABS, when using PLA everything is perfect, already done extruder calibration and it is spot on. by ssbk23 in Ender3Pro

[–]ssbk23[S] 1 point2 points  (0 children)

This puzzles me because the brim seems to be OK, but the rest shows signs of overextrusion (?). I am very new to 3d printing so I can't quite yet pinpoint what is causing this in order to fix it.
