New force-sensing effector, installed.
@Robert_Quattlebaum_d m been wondering how does it work?
@Robert_Quattlebaum_d is it inductive?
Uses force-sensitive resistors. More info later.
Probe type is much simplified and cost effective I think
Awesome, can’t wait to see what you came up with
Bad news: this design was more trouble than it was worth. Getting the FSRs to work reliably was a total pain in the ass.
Good news: Better design is in the works.
I think for the Force sensitive Resistor to work reliably you need to apply a preload on to it.however having said this, I have never use one before and don’t know the full capability of the sensor. Base on my experience with other resistor type sensor/transducer, the main part that you need to have is the ballast ( due to lack of a better word / can’t think of the name) resistor that make up the voltage divider. If the output of such divider is to small to be able to use the full range of an ADC, you need to use a op amp ( operational amplifier ) to increase the useable range. Similarly if you really want to make the sensor sensitive, you could always try the wheat stone configuration. That configuration is being use in almost all resistive type transducer sensor.
Can you tell us on how does this configuration will help you in determining the slop/ incline of the hot bed?
I see that your trying to do there. You wanted to have the force sensitive resistor to give feedback to the controller if the extruder come across some torque. I thin in this configuration, it won’t work reliably since the whole set up is a fix as one item( due to lack of a better word). It would be great if you could either make the extruder hot end floating, using a constrain design but connected thru a spring.
It might be helpful to look at my earlier post of me putting it together to get an idea of how it was supposed to work.
My problem was that the repeat ability was poor and it was very difficult and time consuming to adjust.
