I am back with the actual results:

I ran the exact same GCode with M221 and M592 enabled and measured all prints again.

There seems to be an effect there, at least the 10-30 mm/s range does look flatter to me. But it is hard to say anything definitive compared to the measurement noise.

On the other hand, if 90 mm/s print speed (~10 mm³/s flow rate) is a hard maximum for the V6 hotends increasing the extrusion rate should not really do anything there. So maybe my calibration routine is somewhat flawed.

Well ... that was a false alarm ...

I checked the height of the sensor and checked the height of the nozzle in the toolhead ... nozzle was below sensor ... so I thought that was fine.

Turns out the round heat-sink has rattled itself lose over time and the heat-brake should have sat much higher in the cooler.

Sorry for the fuzz 🙂

Ok ... that makes sense 👍

@dc42 said in Can I use an IR sensor as the X and Y endstop?:

There are much simpler Hall effect endstops available, all you need is a 3-pin IC and a capacitor.

Oh wow, I was not aware of using hall effect sensors for endstops I just googled it. lol That looks like a great way to go. I see a lot of them on amazon with led and resistor on board already. I dont wanna have to solder pc boards so i will try some of these pre made ones
