So I got my mega flashed with the no lcd and 5/16 rod firmware last night (B16_32-LCD-112515).
I connected up my drivers and steppers. I can only get movement when I click on the home buttons. Nothing when I try to move them on the control screen. The server seems to think they have moved as the position indicator has moved on screen.
Power wise I only connected the outside set of positive and negative. Do both sets need to be connected? As far as I know the other set is for powering a hotend and bed which I do not have connected.
I have no end stops connected at the moment. Drivers are 8825 plugged in correctly with the pot facing the power plug.
Anyone know what is going on here?vicious1KeymasterMay 25, 2016 at 7:42 amPost count: 2649
It is behaving like you have endstops plugged in. Either you changed my firmware or you have something plugged in to an end stop port.JasonParticipantMay 25, 2016 at 7:50 amPost count: 322
Nope. Just straight uploaded the firmware and only drivers and motors plugged in.vicious1KeymasterMay 25, 2016 at 7:55 amPost count: 2649
Check your ramps shield then sounds like you might have a short, or a bad board.
Inspect the board around and under the end stop pins. This happens, I have to test every axis on every single board I sell, usually sloppy solder is causing a short or your board is bad.JasonParticipantMay 25, 2016 at 7:58 amPost count: 322
Ugh… Probably right. Cheap Chinese crap. Will inspect tonight.JasonParticipantMay 25, 2016 at 10:42 amPost count: 322
Would it make any difference if I added that U8Glib… I was having issues uploading at first and so I added that library. But I see for this version of the firmware I do not need it.vicious1KeymasterMay 25, 2016 at 10:57 amPost count: 2649
No, the firmware doesn’t call it so it won’t get compiled in.
You can always try bending the endstop pins so they don’t plug into the arduino. The traces are easy to follow on the bottom of the shield.JasonParticipantMay 25, 2016 at 11:00 amPost count: 322
If I am not mistaken there is a command I can run that would check the status of the end stops… That should tell me if there are shorting no?vicious1KeymasterMay 25, 2016 at 11:07 amPost count: 2649
Sure, I’m not sure what it is though.JasonParticipantMay 25, 2016 at 5:52 pmPost count: 322
All min and max endstops show open for x y and z
was getting a checksum error as well but i think that is because I dont have an sd card reader
would the mintemp error cause this?
1 pin is loose. The single pin just above all the end stop pins. Its label 12c on my ramps what does that one do?

SUCCESS… I can move them! Printing of the new center has started… Hopefully about a week and I can get this thing dirty!
Thanks for your help Ryan
