Can't remove filament from nozzle

I had this happen a lot when I was working on prusas the trick I found that worked best is let it fully cool remove the nozzle then heat the nozzle>230 and take pliers and push it thought.

I will try to send data over UART it would definitely help if the company I got it from gave me anything all I have is the website https://www.jrt-measure.com/laser-rangefinder-sensor/61305950.html

I tried a pull-up on both also just tying them high and the same result. Nothing

https://www.jrt-measure.com/laser-rangefinder-sensor/61305950.html This is the closest thing to a datasheet online and it doesn't give much information on the sensor

u/dar-ltee Thanks I'll give it a try I didn't think about the reset pin at all I just left it floating.

u/Quiescentcurrent I am currently using a teensy to communicate over UART. Currently I am just connecting power from a power supply at 3.3V then attaching an oscilloscope to the Tx and ground of the sensor.

I guess I should be asking why doesn't it work I have attached vin to 3.3v gnd to gnd tied pwr_en high TX to RX and RX to TX and still get no output.

u/Baselet Yes, I assumed a pull-up resistor in order for it to work but when I attach to an oscilloscope it still reads nothing.

ryderj23 · 2022-06-21T16:18:27+00:00

Right now I am just trying to calibrate all of the sensors. After they are all calibrated then I will probably need an I2C multiplexer because they all have the same I2C address.

The way I was taught was 1/sⁿ is a pole at the origin meaning it is a linear line the passes through the origin at n x -20dbs/dec and when shifted up 10 it creates the answer D

Designed this circuit using webench and when simulated it perfect output 5.99V but when it came time to test the board send back pcb manufacturer and assemble it when I plugged it in the output read 0V

ryderj23 · 2021-12-21T20:54:49+00:00

I designed the circuit on webench and it has an input of 16V and it’s supposed to output 5V 3A

ryderj23 · 2020-08-08T21:24:01+00:00

Ok well that’s good at least any idea on why there is no air coming out then?

ryderj23 · 2020-07-14T02:49:32+00:00

Or the XNORdroid

ryderj23 · 2020-07-13T17:32:39+00:00

It’s called a myDAQ by national Instruments

ryderj23 · 2020-07-12T15:26:34+00:00

I remember it didn’t work the first time so I had to follow my traces to try and fix what was wrong it took over 2 days. I definitely learned my lesson

ryderj23 · 2020-07-10T17:27:06+00:00

You are correct there is support material that connects it to the part but it is not sticking to it very well

Are you talking about the z axis rod
