I had a Green SN04-N NPN NO 8-24volts it worked perfectly for the 6 months that I used it. Though I wanted some thing that did not hang 65mm behind the nozzle. So decided to look around and found these low profiles Flat Inductive Proximity Sensors by Omron TL-W3Mc2. Had to invert the End_stop switch but other wise it sits within 25mm of the nozzle, could be closer though did not see why. workinby Roberts_Clif - General
QuoteDust "IR Temperature gun" are crap They cannot measure reflective or metallic surfaces (and most of them the "laser" pointer is nothing like where its looking) get a thermocouple eg I have a ADM02 with a temperature Probe. What they called a temperature Probe anyway is a thermister hanging an a pair of stiff wires.by Roberts_Clif - Firmware - Marlin
Quoteobewan Sounds like you motor is struggling with the extra speed. So, basically you have gone from ~82 steps/mm up to now 400 steps/mm , you will have to also lower the max speed so you are not trying to drive the motor too fast (ie the buzzing noise you here) X Y Z E #define DEFAULT_MAX_FEEDRATE { 300by Roberts_Clif - Prusa i3 and variants
I have had this problem myself just recently. It appear that they may be scrimping on the insulating material to save costs. Was planing to buy some 3mm standoffs or button head screws and High temp Epoxy, Adhesive or Putty and glue the thermisters into the standoffs. They have many different types ranging to 350C to 1000C used mainly for exhaust repair and high temp gaskets. short time solutiby Roberts_Clif - Prusa i3 and variants

I entered the 400 as did Bee69, but I am getting no movement, I can hear the motor trying to turn but no movement, I also changed the motor from nema17 to 14, maybe this is the problem, I don't know.

3950 Thermistors are generally 100K @ 25C, Heat water to 25C measure the Resistance. Could be a bad or maybe it is the defective thermister. Item:NTC Thermistor Model:B2-100-3950-1 R @ 25C: K 100K-1% B25/50:K 3950-1%by Roberts_Clif - Firmware - Marlin

It is hard to tell you that you need a larger power supply, as someone tole me that I needed a larger power supply after purchasing it found that the wire was the problem.

QuoteDust you can get a binary dump of the firmware from the controller using avrdude, its command line, and syntax is dependent on your controller CPU type. You should also backup the eeprom google "backup firmware avrdude site:" The only thing you can do with this is put it back onto an identical controller, you cant edit it.
