I have just got another printer fired up and running and it has been working great on those 10mm calibration cubes but when I try a bigger print, i get a clicking sound from the drect drive extruder where the motor trys to move but can not.3 Any Ideas?

I had dialed my motors in using the turn them down till they stall and then turn them back up an 1/8 (I had missed the v-ref method). Between that and a hard bump to my printer table I had them up in the ranges where you have them and they were behaving exactly as you descriped on X, Y and E. Truns out my E was set to 0.68 when it started stalling. After turning it back down to 0.4 it hasn't missed a lick. None of my motors got hot though, that's why I never expected anything. I thought if I had the current too high they would get hot and the stepper drivers would shut down for a length of time. Now I think just the stepper what shutting down, but I expected the motor to go full off when that happened not hum, squeal or anything else.

Good luck. If the problem persist I encourage you to join #reprap on freenode.net IRC and discuss it there. Lots of smart helpful people haning out there. I often get near instant answers or atleast great ideas to try.]]> appdev007 Reprappers Fri, 28 Jun 2013 00:24:10 -0400 https://reprap.org/forum/read.php?4,221870,222160#msg-222160 https://reprap.org/forum/read.php?4,221870,222160#msg-222160 chris33 Reprappers Thu, 27 Jun 2013 18:48:31 -0400 https://reprap.org/forum/read.php?4,221870,222152#msg-222152 https://reprap.org/forum/read.php?4,221870,222152#msg-222152
I'm assuming you have pololu stepper drivers. Take a look at this pic. If you don't have at least 0.4 VDC here then they are probably set to low unless you have some non standard (smaller) motors. Here is the article that goes with the pic.]]> appdev007 Reprappers Thu, 27 Jun 2013 18:08:51 -0400 https://reprap.org/forum/read.php?4,221870,221967#msg-221967 https://reprap.org/forum/read.php?4,221870,221967#msg-221967 Gibbedy Reprappers Thu, 27 Jun 2013 06:23:16 -0400 https://reprap.org/forum/read.php?4,221870,221870#msg-221870 https://reprap.org/forum/read.php?4,221870,221870#msg-221870
