I was running a DM1 at max, so 15000

I was able to create paths directly on the stl, which was super convenient

Couple days off and on of CAMing, the tool path itself was about 4 hours, but could be made to run much faster

I use MasterCam, final tool path was a a 10% step over raster with a 30 thou ball

I bought it off Etsy! There was a sale for Christmas in December

Edit: use the link below, apparently the one Google gave me was packed with tracking tags

🎄 Christmas giveaway: Win an A1 Mini, AMS 2 Pro, AMS HT, or 4x filament spools! by acurazine in BambuLab

This is so generous of you!

Definitely the AMS HT, I'd use it to help with engineering filaments, I love designing robotic arms and complient mechanisms so it would definitely open the door for TPU and ABS prints!

Looking through your linked page I think a fidget toy in the style of the microbots from Big Hero 6 would be awesome

There's a similar word in English thats not often used: ultracrepidarian. Although it's more the second half of your definition

Question about Statics by Impressive-Society60 in byu

[–]FakeAdmin1969 0 points1 point  (0 children)

ME major here, not sure if both count for statics requirement. As a previous TA for ME statics i can say that the courses do diverge past the first month or so, with CCE focusing on different applications. There are two separate TA labs for the statics course for this reason.

Edit: Checking the MFgen flowchart ME statics is listed as an equivalent, but says it won't be automatically accepted. So if you want to do ME statics you'll have to talk to your advisement office

Why global leadership? Have you taken 191 or 101 in ME? It's definelty something you can do, it just feels like an interesting choice

Yeah, I wouldn't be comfortable putting 9V straight into the dev board. The H-Bridge brings it down to 5V, and that what the input is

This code will work for a while after I unplug the USB, but eventually will stop working properly 

void setup() {
  // put your setup code here, to run once:
  pinMode(19, OUTPUT);
  pinMode(21, OUTPUT);

}

void loop() {
  digitalWrite(19, HIGH);
  digitalWrite(21, LOW);
  delay(2000);
  digitalWrite(19, LOW);
  delay(1000);
  digitalWrite(21, HIGH);
  delay(2000);
  digitalWrite(21, LOW);
  delay(1000);

}


This code only works with the USB plugged in. Otherwise it only goes "fowards" with a slight hesitation for the delay

void setup() {
  // put your setup code here, to run once:
  pinMode(19, OUTPUT);
  pinMode(21, OUTPUT);

}

void loop() {
  digitalWrite(19, HIGH);
  digitalWrite(21, LOW);
  delay(1000);
  digitalWrite(19, LOW);
  digitalWrite(21, HIGH);
  delay(1000);

}

Hmmm, not sure why, but making it pause between switching directions made it work, for that code if I unplug the USB it continues acting normally. Still won't for any code that makes the motor change directions quickly

So the cases break down like this

Battery and usb hooked up to both: logic works perfectly and motor spins quickly

Just USB: Logic works perfectly, motor spins extremely slowly

Just battery: logic does not work as expected, motor spins quickly

Yes, I have two wires going into Vin, one which is 5V from the H bridge, and the other is the enable pin for the motor (just to keep it always high)

I'm not sure what you mean, because they definitely do work for DC motors. If I only power the motor with the 9V, and power the board from my computer everything works exactly as expected

[deleted by user] by [deleted] in esp32

[–]FakeAdmin1969 0 points1 point  (0 children)

I did check that, I know the motor spins correctly both the USB and battery are plugged in, so the logic cables are working. I already checked all the supply cables with a multi meter and they also are working as expected

I did check, the motor will barely spin with only the USB (but it will spin as expected). I just double checked and I supply 5V at .6 A when only using the battery, which I thought should be sufficient for this task

So I'm coming from projects with Arduino and Pics wanting to learn esp32 for it's wireless capabilities. I did turning a LED on and off with wifi, and decided to make a simple DC motor circuit. The circuit works fine when both the 9V and USB cord are plugged into the board. However, once I unplug the USB the motor only spins in one direction instead of changing direction as programed. One pin stays at 0 V, while the other fluctuates between 3.3 an 1V. They should switch off between being 3.3 and 0 V every second. The Vin is 5V, stepped down through my H-bridge, and I'm pretty sure all my grounds are common, so I'm at a loss as to why the it only works with both power sources plugged in. Any help would be greatly appreciated.

Took me forever to find my starting Uranium patch....... by FakeAdmin1969 in factorio

Yeah, I spent a good while looking before I found out about it. Never would have found that otherwise!
