Hi there. I have purchased a RAMPS 1,4 board + Arduino MEGA 2560 R3. I have uploaded Teacup firmware. Heatbed and Extruder heater seems to heat and temp reading seams about to be right. Extruder motor works right. BUT none of my X,Y or Z axis are moving at all. ( I have checked the different motors by hooking them up to the extruder and they all work, so it is not a matter of wrong cable connection.) So i started looking a little at the pin assignment. I think i have wrong pin assignment. I see pin 54 for the x axis, when i look at the RAMPS wiki, but on the Teacup is shows DIO01. How to assign pins ? Any help appreciated Wang Fei https://reprap.org/forum/read.php?1,329719,329719#msg-329719 Fri, 14 Aug 2026 05:49:09 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,329719,329815#msg-329815 https://reprap.org/forum/read.php?1,329719,329815#msg-329815
2. In your config.ramps-v1.3.h section 3 is called pinouts. Should be able to make your changes there
