Endstops acting odd :S Well, here's a bit of what I've got to fix: [imgur.com] It reads two endstops pressed when only one has been. It seems to be affecting the Z axis, then somehow seems to "infect" the Y axis switch. for now, I don't have any pics of the board, but I don't have any LCD board, and I'm running Marlin, and I have tried to re-upload the config.h with different pull-up configs on the endstops, just to see if that would fix it... long story short, it didn't and I"ve since reconfigured the board back to the way it was before. I was out of town for a buisness trip for three weeks, so I hadn't printed since the begining of June... and I had no probelms then. If I could get some help, I would appreciate it :) (I've got something that I want to print for this weekend!) Thanks!

As for the Wiki, it seems to be good, but the section that gave me the Idea was the electromagnetic noise part. What I essentialy did, was create a shielded cable by wrapping it with aluminum tape. The Idea seemed to work, but after one or two sucessfull prints, The same thing happened, which is making me think that my motherboard has a short.

So I guess, my next question would be relating to the Sang board and the Marlin firmware.

At least until I have some more Cash on hand to get a new board, I need to keep this printer working. So in the meantime, I would like to map the sensor input to a different set of pins on the sanguinololu. What I need to know, is what pins do I set them to in the pins.h section of the marlin firmware? Is this possible? (if possible, what I would like to do is swap it with the bed temp pins, because I don't have a heated bed, and am currently limited to PLA)

Thanks]]> Skidd Sanguino(lolu) Fri, 04 Jul 2014 12:43:03 -0400 https://reprap.org/forum/read.php?158,376879,377974#msg-377974 Re: Endstops acting odd :S https://reprap.org/forum/read.php?158,376879,377974#msg-377974

Well, that did give me an idea of using metal tape to wrap my cables....

Obviously I didn't write as well as intended. Concerning about disconnected signal wires is a waste. Either you connect them or disable them in firmware. Could you please improve what I wrote there in a manner understandable by everybody? Thanks a lot!]]> Traumflug Sanguino(lolu) Fri, 04 Jul 2014 06:43:28 -0400 https://reprap.org/forum/read.php?158,376879,377867#msg-377867 Re: Endstops acting odd :S https://reprap.org/forum/read.php?158,376879,377867#msg-377867
EDIT: Well, that Idea fixed it! :D so, I guess, if the cables don't have any kind of shielding, this may help! Metal tape is generally found in the heating and A/C section, because its used for sealing air ducts. generally a roll is pretty cheap, $7 - $10 USD.]]> Skidd Sanguino(lolu) Thu, 03 Jul 2014 23:00:45 -0400 https://reprap.org/forum/read.php?158,376879,377127#msg-377127 Re: Endstops acting odd :S https://reprap.org/forum/read.php?158,376879,377127#msg-377127 endstop testing and troubleshooting guide.
