I’m trying to load Marlin 2.0 on my arduino mega + ramp 1.4 + LCD 2004A, but I don’t get information on the lcd screen and I’m going crazy because I can’t find where the fault is, I have tried to install the software for BQ Hephestos and in this case yes It works fine, I get the information on the screen, which I am doing wrong. There are more details about getting the Marlin firmware and flashing it in the docs: The only way to test is to go through the setup and see if they work. It is very possible that either the drivers or the mega have broken. Otherwise, the machine will try to move way too fast. You should install all the jumpers under the drivers to enable 1/32 microstepping. If you don’t adjust the current, they will overheat, or “skip steps”. You will need to adjust the current on the DRV8825s though. It does not need any additional configuration. The firmware from Ryan’s github already has been configured for CNC work. You can run two motors off of a single driver by wiring them in serial: I would not start with the dual endstop version, because it is more advanced. The recommended firmware for RAMPS is Marlin, configured by Ryan. So you will need another motor eventually. The MPCNC and LowRider2 both use 5 motors. Hopefully, the translation back to Spanish works well enough for this conversation. I know some Spanish, but I won’t torture you by trying to write anything but English. I can read your posts just fine through google translate.
