Hi, I am currently using marlin firmware with ramps 1.4. I have tried manually move the stepper motors. It seems to work pretty well but, when i tried printing something the z axis doesnt moves :( Any one can help?

Its not orca. Its custom build portabee :) Finally, I got it working. Something wrong with the z axis values. Its ok after i calibrated it :)]]> zhenning General Wed, 14 Aug 2013 13:13:14 -0400 https://reprap.org/forum/read.php?1,234656,234807#msg-234807 https://reprap.org/forum/read.php?1,234656,234807#msg-234807 Here was my problem
You can go through this thread, maybe it will help.

Ultimately, the firmware safeties kicked in.]]> Mogal General Sun, 11 Aug 2013 14:41:00 -0400 https://reprap.org/forum/read.php?1,234656,234686#msg-234686 https://reprap.org/forum/read.php?1,234656,234686#msg-234686
Config looks ok to me, but it seems strange to use all 6 limit switches. you may want to install all of them for z axis to work correctly. z homes at top on the orca correct?]]> jamesdanielv General Sun, 11 Aug 2013 04:44:40 -0400 https://reprap.org/forum/read.php?1,234656,234656#msg-234656 https://reprap.org/forum/read.php?1,234656,234656#msg-234656
