I have endstoppullups defined in my config file, is that not internal pull ups? I'll have to go back through my config and see what its doing.by Lebanese - Mendel90
If I manually hold the Z axis endstop and turn on the printer it'll return all values as open. If I let go and M119 again it remains open and pressing it again will cause no change in reading. I've also replaced the endstop in case it was a faulty switch.by Lebanese - Mendel90
Upon further inspection it seems I am running a fork #define STRING_CONFIG_H_AUTHOR "ErikZalm+nophead+neildarlow" // Who made the changes. Perhaps its a fault in the rambo board?by Lebanese - Mendel90
Strange problem I can't seem to figure out. My machine will not recognize my Z end stop if its triggered during power up. For some reason when I home all my axis trigger the end stops and remain there, but if I power off and on the end stops are no longer recognized as being triggered. My understanding of Marlin is that its suppose to trigger an endstop than back off 1-2mm to untrigger. As of nowby Lebanese - Mendel90
I have not looked into the efforts being already tried. But I had a idea while trying to level my bed that maybe someone can expand on. What if we placed strip of something conductive around the edge of the printer bed with it wired as a ground to a endstop. Than make a holder that can be either clipped to the hotend or attached to the hotend bracket. Use a simple probe that could be turned parby Lebanese - Mendel90
Well after finally ripping the hotend apart and doing some testing via I made some tables. I had a friend come over and assist with a infrared thermometer the final result is my thermistor is garbage so I have a new one on it's way. Lesson learned the hardway - Don't skimp on some parts!by Lebanese - Mendel90
Thanks for the reply, I have tried setting my hotend to 195 from there I raised the temp in pronterface by 10 degrees each time while trying to force PLA through the hotend by hand. Even when I set pronterface to 260 (the max allowed by firmware) I couldn't feed any PLA through by hand. When I set my heatbed to 60 C my thermometer reads 48 C So i'm more than 20C off in temp which I assume gby Lebanese - Mendel90
I'm at my wits end.. I had problems with my Melzi not reading the correct temp in pronterface. My heated bed uses a Epcos B57861S104F40 100K 1% thermistor and the temp was reading 20c over room temp. I soldered two 9.1k ohm 1w resistors and the temp finally read correctly on the hotend and bed. Now the problem is my hotend(http://www.ebay.com/itm/271339421020) doesn't seem able to melt any plastby Lebanese - Mendel90
