Quotedc42 Marlin has not been ported to the Duet. The Duet runs RepRapFirmware instead. ohh, I thought the firmware for Duet was your Marlin build. It would be really nice if there was some documenation as to what sensors could be used and how - step-by-step. A why would be nice, but the how is the important part. Often "guides" are made up of "whys" and then assume people can figure out the hoby dintid - Controllers
Quotedc42 RepRapFirmware does not use thermistor tables, you tell it (via the config.g file) the R25 and B values of the thermistor you are using. A PT100 thermistor + amplifier does not produce an output like a thermistor - in particular, the amplifier output voltage increases with temperature, where as the voltage across a thermistor decreases. So the firmware would need code changes to supportby dintid - Controllers
Quotedc42 Quotedinted The output table is strictly for 5v. It changes dramatically if there are variances in voltage input. This is the main reason I run it from a dedicated small 5v psu instead of from AUX power on RAMPS, as it wasn't really stable.

Quotedc42 I looked into this a couple of weeks ago. First problem is that the E3D docs say nothing about whether it can be run from 3.3V and still give accurate results.

Do 1 thing at a time: 1: Make sure you can move the Axis correctly - if it does not, either correct the wires or invert axis in firmware. - When 1 is in place, move to 2: 2: Define which way the Axis needs to go when homing by using either X_HOME_DIR -1 or 1 Edit: changing multiple configurations options at a time when setting up these tings, will just screw with your headby dintid - RAMPS Electronics
You dont want to both change firmware direction AND swap wires. Change wires back. Reason motors stutters now is propably because the two coils are working opposite each other now. That or you have set wrong microstepping, if you have changed that as sell?by dintid - RAMPS Electronics
Hello 2YRRAH You can safely connect 12v to Arduino Barrel regardless of wheter you have D1 in place or not. Same goes for USB. D1 Works by powering the Arduino through the Ramps, so you should not need barrel or usb if D1 is in place AND you feed enough 12v amperage through the 12v 5amp connector on the Ramps? If the power-source through ramps is too weak (or you have some faults on ramps, or mby dintid - Controllers
Quoteo_lampe Check if diode D1 is there on Ramps and mounted in the right direction. #see attached pic Then you should check if arduinos 5V regulator is working before you can even think of doing any mods to Ramps or LCD. DonĀ“t feed 5V to arduinos barrel connector as proposed before. The regulator needs at least 7V input voltage to work properly. With only 5V input the risk of overheating MOSFEby dintid - Controllers
Mine runs fine on 5v AND when using 12v to ONE of my boards, it fails to output 5v on AUX connections.

Wanted to show my before and after photos of getting my Ramps to run on 24v.

All arduino mega Can handle 12v input as Well. Split the 12v power going to ramps and find a barrel-connector that fits into the arduino Board. If you have a seperate 5v source, then you Can use that instead. Using 5v input Will put less stress on the arduino converter that supplies 5v to certain Ramps 5v outputs. I have been running wih 12v for a year without issues though.by dintid - Controllers
