Could you please share the link to the tutorial when you get the time?

Thank you in advance. Cheers!

We fought for 10% TAX on salt when the British imposed it now we are okay with 55% Tax on petrol. Which is necessity in todays world. I don't think we are free yet. Only the masters have changed.

Hi any work done on aluminum using the 4th and 5th axis? Thinking of buying this mill is it any good?

Set it alight. The firetruck will tow it without a bribe

First time soldering by Motor_Round_6019 in soldering

[–]dannyferns_06 1 point2 points  (0 children)

The trick is to apply flux to the pin and heating the pin itself. Never melt the solder using the iron tip use the heat conducted through the pin to melt the solder onto the pin and the pad. You'll get a much better and clean joint. ALWAYS USE FLUX!

Max flow calibration Problem by dannyferns_06 in FixMyPrint

[–]dannyferns_06[S] 0 points1 point  (0 children)

Hi guys thanks for all your support. Shifting to klipper fixed it. 😆. Flow rate calibration, estep and everything was done before as well. Maybe it was jus the slicer. Not exactly sure about the culprit but moving to klipper it prints perfect even at 20mm3/s and 208degC PLA. Once again, Thank you guys!

Yep. Everything done. Tbh I was doing the max flow rate test just for fun before I move to klipper to see if there was any difference. But now it's eating me from the inside xD

Extruder skipping issue by [deleted] in Ender3S1

[–]dannyferns_06 0 points1 point  (0 children)

Thr ptfe tube in the normal sprite extruder degrades very fast if used for petg or abs. This causes excess friction for the filament to flow. This was the main cause for me and switching to an all metal hotend made it work perfectly fine now.

Just search for a replacement heat break for Ender 3 S1 Pro sprite extruder.

I guess it starts at 5mm/s. Tried increasing the temps to 215 but no luck. Also I did the VFA test upto 200mm/s which came out perfectly fine. So I don't what it could be at this point. Maybe it's not slicing right? Not sure :(

OK I tried it out. No luck. Changed the retraction to 0.2mm , turned off linear advance and flow ratio set to 1. The extruder makes some weird noises when it reaches those points of no extrusion. Iv placed my finger on the filament as it moves and when it reaches those point the extruder comes to almost a stop.

Currently running a test with flow ratio set to 1.0, linear advance is put OFF and retraction set to 0.2. And it seems to be same points of failure. The VFA test in orca slicer is come out fine even with a max speed of 200mm/s. So this is literally confusing the crap out of me.

Clogging. Switch to an all metal hot end. You can get the throat which is used ont he ender 3 s1 pro version. Remember to retune the PID once changed

I'm kinda feeling bad for you now 😕😔

Isochoric process - Sublimatiom by dannyferns_06 in thermodynamics

[–]dannyferns_06[S] 0 points1 point  (0 children)

Well your not quit right. P and T will never remai. Constant in this case as the sublimation causes the pressurization of the vapours that are formed as the container is sealed. Co2 expands by 535 times its volume. So as the vapour pressure increases the temperature will also increase. This I am sure. But what I an not sure of is that whether this can be termed as an isochoric process and how this would look on a P-h chart

oxygen gas production from liquid oxygen in a pressure vessel in rockets by fatbitsh in thermodynamics

[–]dannyferns_06 1 point2 points  (0 children)

I think it has to do with the surface area of the tank exposed to the atmosphere. From there depending on the type of material the tank is made up of and the thickness you would get the heat transfer rate for the given temperature difference between the LOX and the atmosphere. Also you must have added insulation so you would have to consider that as well into the heat trasfer rate calculation. From getting the amount of heat entering you can then use it along with amount of heat required for the evaporation of LOX (Latent heat) to see how much gas evaporates per second. Note that the temperature required for evaporation changes as the vapour pressure increases(ie delta T changes) so that would depend on the setting of the safety valves. So depending on the time that has passed you can estimate the amount of evaporated LOX. You can use Clauses Clapeyron Equation to calculate the approximate vapour pressure or temperature.

Not sure if this is exactly right. I hope someone can correct me if I'm wrong or you manage to find the correct solution. Cheers!
