Occasional Locking/jamming of an axis

[benhowes]

Occasionally one of the axis, usually, though not always, the Z-axis kind of locks up. It's not stuck, but it just kind of vibrates back and forth when its supposed to turn and is still like normal the rest of the time. It remains like this until the board is reset with the button. There doesn't seem to be any pattern as to when it happens.

I'm using a gen6 board and I have spoken to crispy1 about this on IRC and he is having the same problem with his ramps1.3

I have been using slic3r if that makes any difference. Pretty much everything is default other than the steps/mm on Z and E. I can post the config if that helps. Someone here has had a similar issue, though having looked at the code, Im not sure how this could've fixed it? http://forums.reprap.org/read.php?146,111112,111112

Has anyone seen this or know what might be to blame?

Hey I´m observing a similar problem with my printer. When I start/reset the printer everything works fine but after I have sent a command to drive along the y-axis the x-axis gets kinda locked just like you have described it.

I´m using Ramps 1.2 ; Arduino Mega ; marlin 1.0.0 Beta 1 firmware ; and pronterface as my host

This is a mechanical and/or current problem, not a problem with Marlin.
Please close this issue.

I agree with nothinman here. Viberating motors is a clear undercurrent/over-accelerating problems. Note that the defaults in Marlin in acceleration are pretty high for most RepRap builds.
