Ramps 1.4 w/LCD will heat, home and turn on the fan, BUT won't print I have a student who has built a MOST delta machine but instead of using a melzi running repitier we are running a ramps1.4 with a rewrap discount 20x04 lcd. We have a 8mb sd card with a gcode program that is about 700k on the card. Using the LCD we can preheat the printer but once we get to our desired temp we attempt to try and PRINT FILE but the printer does nothing. Is there something that would disable printing from a SD in the repitier firmware? https://reprap.org/forum/read.php?219,553249,553249#msg-553249 Tue, 21 Jul 2026 15:46:19 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,553249,616149#msg-616149 Re: Ramps 1.4 w/LCD will heat, home and turn on the fan, BUT won't print https://reprap.org/forum/read.php?219,553249,616149#msg-616149 Rogue Scholar RAMPS Electronics Tue, 26 Jan 2016 16:48:50 -0500 https://reprap.org/forum/read.php?219,553249,567888#msg-567888 Re: Ramps 1.4 w/LCD will heat, home and turn on the fan, BUT won't print https://reprap.org/forum/read.php?219,553249,567888#msg-567888 Rogue Scholar RAMPS Electronics Wed, 07 Oct 2015 16:23:59 -0400 https://reprap.org/forum/read.php?219,553249,557260#msg-557260 Re: Ramps 1.4 w/LCD will heat, home and turn on the fan, BUT won't print https://reprap.org/forum/read.php?219,553249,557260#msg-557260 Then you should check if arduinos 5V regulator is working.

Does the printer move under manual control or when printing via USB?

Yes we can home from the controller and the USB. The print option on the controller is not being registered as a command. Now it's acting as if the ramps shield is not getting any power. When our 12 volts DC power is plugged into the ramps board the screen does not come on, however when the arduino is plugged into the computer, the screen powers on.]]> Rogue Scholar RAMPS Electronics Fri, 11 Sep 2015 16:12:31 -0400 https://reprap.org/forum/read.php?219,553249,553348#msg-553348 Re: Ramps 1.4 w/LCD will heat, home and turn on the fan, BUT won't print https://reprap.org/forum/read.php?219,553249,553348#msg-553348 X0 Y0 Z"max" coordinates?

The gcode file should already contain temp-settings and homing command.
Why don´t you just run the gcode file?
