One Bright Second

The last stars will die out 120 trillion years from now, followed by years of just black holes.

Condensed, that’s like the universe starting with 1 second of stars and then a billion billion billion billion billion billion billion years of just black holes.

Stars are basically the immediate after-effects of the Big Bang. A one-second sizzle of brightness, we live in that one bright second.

3D Printer: Extruder Calibration and Estep adjustment

To calibrate your 3d printer’s extruder

We need to know the printers current e-step value, and a physical steps/mm value (what the printer is actually spitting out). This calibration is especially important if you’re changing the extruder from one that uses gears like the Titan Extruder found on Anycubic printers to a spindle drive.

Determining your current steps/mm value for your 3D printer

Connect PC to USB port on printer.
Download and run “Pronterface”.
Set Baud Rate to 250,000 and select your COM port.  Make sure you have closed any other slicers such as Cura as they make try and take control of the COM port thus making it impossible to connect in pronterface.

Once connected, In the Command Window enter M503 (report settings)
Look for a line starting with M92 and at the end you’ll see your current e-step (steps/mm) value

example. echo: M92 X80.00 Y100.00 Z400.00 E405.00

Determining the physical steps/mm value for your 3D printer

Heat the extruder on your printer.
Using calipers (or ruler) and a sharpie, place a mark on your filament at 120mm from the entry hole to your extruder.

In pronterface,  Send: G1 E100 F100
This tells the printer to slowly extrude 100mm of filament

Determining the correct steps/mm value for calibrating your 3D printer’s extruder

Measuring the distance from the extruder to the mark on the filament, then subtracting that value from 120:

  • 120 – [length you just measured from extruder to your mark] = actual length extruded

Next, we need to know how many steps the extruder took to extrude that much filament. We can determine this value by multiplying the current steps/mm value (found earlier by issuing an M503) by the length we should have extruded, in this case 100 mm:

  • [steps/mm value] x 100 = steps taken

Using this, we can obtain the physical, correct steps/mm value by dividing by the length extruded:

  • [steps taken] / [actual length extruded] = [accurate steps/mm value]

Now, all we have to do is set this as the printer’s steps/mm value, and we should be good to go!

Saving the correct e-steps/mm value for your 3D printer

M92 E <new step value> (sets the new step value)
M500 (to save)
M501 (use new values)

Pro Tip: If your printer stops responding in pronterface.. try a disconnect / reconnect then issue the command again.

Self Respect

You aren’t afraid to say “no” when it’s necessary.

You care for others, but not at the expense of your own well-being.

You aren’t afraid to end toxic relationships, or relationships you’ve outgrown.

You’re able to let go of the things you can’t control, and focus on what you can.

You give up trying to control or change other people. You are able to “detach with love”. You know that it’s not your responsibility to change them.

You are able to pick your battles. You are able to discern what’s important to you, what’s urgent and what can be dealt with at a later time, what this approach and that approach will realistically accomplish, etc.

You understand the difference between forgiveness and reconciliation, and you know when an apology is sincere and when it’s not.

You are patient, but not at the expense of your own well-being. You don’t let people string you along with excuses and empty promises.

You don’t react, you respond.

You ask for help when you need it.

You make sure that when you help others, you’re really helping them and not enabling them.

You have a strong set of morals and values, and you don’t compromise on them.

You choose your own life path, even if it means disappointing some people, such as your parents.

You take care of your body, but at the same time, you don’t loathe your body as it is now. You eat healthy, but you don’t let your diet make you crazy, or assign moral value to food (or to yourself for eating those foods).

You might not be thrilled when you get rejected. (I honestly don’t know anyone who would be.) But you are able to accept that, and not chase after or berate the person who rejected you.

You don’t tolerate bullying or gossip. You have no room in your life for drama.

You don’t participate in other people’s drama.

You stop people-pleasing.

Lack of planning on someone else’s part is not an emergency on yours.

You take responsibility for yourself, but not for other people.

You stop making excuses for other people, or covering for them.

You know that if your marriage or relationship fails, it doesn’t mean that you are a failure.

You’re able to let little things go. And you keep it in perspective: you know what is a little thing you can let go, and what’s something you need to put your foot down about.

You don’t let yourself be pigeonholed into roles you aren’t suited for or don’t want to play because of your gender or what have you.

You are your real, authentic self in your relationships, not playing a role.

You know that relationships are a two-way street. And while you realize that no relationship is ever going to be a perfect 1:1 ratio of give and take all the time, it also shouldn’t be one person doing all the giving and the other doing all the taking.

You don’t feel exhausted, drained, or resentful, because you are able to set strong boundaries.

You stop letting fear of rejection or abandonment have power over you.

You are able to express your needs and feelings, and to know what those needs and feelings are in the first place.

You give yourself time to rest and recharge.

You give yourself as much respect and care as you give to others.
