Hello Dragonator,
electronic components have a relatively high deviation from the nominal values. I would imagine that some FETs open at 5V, others have not. Then your measurement results are pure coincidence.
Strange is that you measure a resistor and other components affect the measurement.

Re: Hacking the HP45
Hello everybody, thank you for your explanations. I have also understood as you have explained that. However, something is unclear to me how the 10x resistance can describe the offset of the temperature sensor. When the 10x is a discrete resistor which is incorporated in the production, there is no ...

Re: Hacking the HP45
Hallo, DigitalShadow mentioned on page 5, such a function and relates to one of the HP patents. If I have understood correctly, the temperature is very important as the point for the release of a drop entscheident depends on the ink temperature. It does initially the enthalpy of vaporization can be ...

Re: Hacking the HP45
Hello, Could it be that you've made a measurement error or allocation failure nozzle 4 and nozzle 5? I try to think without limitations where used to the R10X: Could the R10X be used to keep the power consumption of the printing head constant? Could it be used for level measurement of ink? Could the...

Re: Oasis 3DP printer
Hello,
I am no friend of crossing belts, which increases the wear and degrades the efficiency.
It is easier to couple the two belts with a third.
Best wishes
Philipp

Re: Hacking the HP45
Hello, this is very interesting, unfortunately I can not recognize the reference measurement in the document. Would it be possible to mount the document in original? As I understand, the R10X as a reference for the line losses, to identify and compensate in the controller. It can be compensated as w...

Re: Hacking the HP45
Hello I would prefer these sensors, I have had good experiences with it. http://www.megatron.de/en/products/hall-effect-singleturn-rotary-encoder/contactless-hall-effect-encoder-series-eni22-ecoturnR.html They are not too expensive. Alternatively, there are also optical sensors. Linear encoders are ...

Re: Hacking the HP45
Hello Dragonator, that's great. I wonder if everything works as it should. I am not ready with my project yet. It will take a few weeks until I can do the printhead installing for the first time. I am very excited about the L6452, if this function, the board is considerably narrower. Then the cascad...

Re: Oasis 3DP printer
Hello, I think with the belt tribes is not so difficult. There is no relative motion between powder and belt, which is good in principle for the process. The belts run in a groove, and are connected to the piston, so they act as a feather key. Maybe you can install a magnet in the piston, and can mo...

Re: Hacking the HP45
That's great. I would be interested how you plan the architecture of your control. I'm always a friend of modular systems because they allow more degrees of freedom. Single print head, multi colour, cascaded print heads .... I would also be interested in how you want to synchronize the position of t...
