I'm reasonably certain that this controller will produce an aestheticly pleasing and reasonably intuitive UI for what my purposes, which is one of the reasons that I'd like to use it. Hopefully I've read the diagrams correctly.Īs I had said, I'm not 100% averse to installing a sacrificial RAMPS shield for a proof of concept, but that's not a good log-term solution, and certainly not if I end up making more of them for other people. (Well, I didn't look too closely at the functions of the other pins on the Arduino.) This is probably more connection than it needs to use the display and encoder, as it also includes the connections to the SD card reader, but I do note that it only shows ground being connected to EXP1 and +5V connected to EXP2. At least in this configuration we might be able to examine the Marlin code as far as pin diagrams go. The schematics connect the pins (Assuming Arduino Mega 2560) EXP1:įor whatever good it does, this will be how the controller is connected to the Arduino via the RAMPS as far as the Marlin firmware is expecting. So looking at the schematics for the 2004 controller adapter and the RAMPS 1.4. If I don't get the SD card, that's fine, I can pump it out via a serial connection to a laptop for data collection. If I can use the SD card slot as well, this would be used for logging the data for later analysis. At the moment it is 'motion controller only' - so no limit switches and no spindle output. If anyone likes to give it a try it is version 9.016 on my homepage. The idea is that I'll be using the Arduino with a couple of MAX6675 sensors to read a pair of type K thermocouples to monitor my car's exhaust gas and coolant temperature at the turbocharger, along with the output of a wideband O2 sensor, MAP sensor, and a few of the on-board ECU's diagnostic outputs for things like fuel trim compensation, injector duty cycle, vehicle speed sensor and airflow meter to get various performance metrics. Hi, I got quite a few requests to add Arduino Mega 2560 / Ramps 1.4 support to Estlcam and finally found some time to port the firmware. (For those who care what the end result will be) SD card write access isn't a must for this, but would be a huge bonus if I can do it. My requirements are to be able to use the 20 by 4 text output and to be able to read the rotary encoder, encoder pushbutton, and possibly the reset button. (Seems unnecessary, but I have at least 2 spare RAMPS shields as well.) I have a few of these controllers, and a use for them that doesn't involve 3D printing, so I have zero need for the Marlin firmware, though if need be, I CAN use a RAMPS shield to connect it. Not sure if the OP has made any progress on this in the last 3 months, but I'm interested in doing something this as well.
