Photo of mainboard needed urgently!
it look like I've teared off resistor or capacitor from mainboard.
Can someone please take a close-up photo of mainboard between ATSAM3 microcontroller and extruder1 hole? Components between C17 and R19.
I'd really appreciate it.
Measurement on R14 and R19 appreciated as well ;)
Sorry, I can not help here.. but a question from a electronic technician...
I did not see the resistor or capacitor positions that you described in this photo. And in the middle, should there not be a BGA component / controller at this position?
Yes, I took that photo a year ago, when I replaced broken MCU.
Now I really need to know the values on those 3 resistors marked on attached picture, as 1k for all of them did not work :(
I get ambient temp of -4, nozzle 'cold'.
What version of the mainboard are you working on? There are at least four that I am aware of in the wild.
THANK YOU! :)
Measured with board connected / in printer or with board removed?
Board was inside "dead" Robox, being used as parts now, with extruder removed by another, un-powered, with no USB cable or power cable fitted, and so "in situ" measurements. Motherboard or logic board was intact though, so nothing unconnected as such. :)
Obviously there might be other components in parallel with these, as I haven't seen any schematics for the board anywhere, so take readings with "a pinch of salt", but I'm guessing 689 is probably 681Ω with tolerances, & the 600Ω might be 590 or 604Ω using SMD components.
PS I believe you might have a parcel on the way too, so you'll be able to measure those. ;)
