Many thanks! I'll adjust the base edges of the surround to be around 1.5mm higher than the bottom edge of the board. Right now they are line-to-line.by rmd59 - For Sale
Quotedc42 I can't be completely sure because the focus of the shot from underneath isn't great, but I think that the edge of the fan duct with the cutout in it for the capacitor isn't sufficiently clear of the IR LEDs and phototransistor. David, is there a minimum recommended distance that the bottom edge of the sensor should clear any surrounding shrouds?by rmd59 - For Sale
Many thanks...here are some more pics with way better clarity!by rmd59 - For Sale

Sorry about that...I brightened it up a bit and circled where the Sensor is. It is completely shrouded except on the bottom which is unobstructed.by rmd59 - For Sale
Many thanks for the quick reply, David! No supports on the carriage or supporting structures; and the phenomena happens even if I run a print at night and then start a new one in the AM...I don't think heating of the components is an issue... New sensor BTW...got it from Filastruder about 6 weeks ago...by rmd59 - For Sale
Greetings All! I have had the MD IR Sensor installed for a number of weeks. One very bothersome problem is that the sensing distance seems to creep(normally driving the nozzle into the bed) after successive prints. I have made sure the mounting and hottend is tight, so I'm pretty sure there are no mechanical issues with the physical offset to the nozzle; the build surface is PrintinZ black. Uby rmd59 - For Sale
