I took my printer down since the hot end was locking up during a long print. I have posted about this over the past year. I recently purchased a new microsd card, put on a new image of Jessie 8.6. I also replaced the hotend thermistor, redid all of the wiring to decrease the effect of EMI near the cartridge heater leads. I got off one reasonable 4hr test print. However, on an overnight, the ADC locked up at maybe the 5 hr mark on a 6.5 hr print (not heating). So, I recall Charles writing about the ADC driver being a bit temperamental, sensitive to over-voltage and such. I am powering the beaglebone through the AUX in on the CRAMPS board through a 5V LM2596 buck regulator (https://www.amazon.com/gp/product/B00WEBJRE8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1). I recently went a made sure that it was set to 5V to be sure. Prior to that I was using a 5V DC adapter where I still had this issue. My cable management is reasonable so I do not think wires are moving about.
1. So what I want to know is whether this is a particular problem that is always going to be sporadic during a print ? 2. Is there no straightforward solution ? I tried several microSD cards, thinking it was a quality issue or corruption of the card but that did not fix it. I also though my thermistor may have been bad, or the wiring out both so I swapped that out, to no avail. 3. There was mention of a buggy ADC driver in an older kernel. Has this same driver been brought along to the new Debian release / 4. I did see in the forums about using an external ADC, is this possible to implement on the CRAMPS (I am not sure if the SPI is broken out). 5. Is this an issue that everyone who uses the Beaglebone/CRAMPS combo, sees ? 6. I slice in Cura, is this a G-code problem ? ( I am not using the remapped G-codes0 7. 5. Does this occur with the Replicape board ? 8. Is it time to throw in the towel ? I really like the using an embedded platform for running a printer. This is a bit frustrating as I can not figure it out. Everyone on this board has been really helpful. I have scoured the board looking for solutions, but am still at a loss (probably since I am not a programmer or engineer !)
