Welcome to the SeeMeCNC Community

Hello,

I recently completed a build from a kit of a Rostock Max V3, and I went to upload the firmware for the Max V3. After going through the steps like installing the driver, and clearing the EEPROM, the firmware said it uploaded successfully, and the LCD Display changed (http://i.imgur.com/GsxdvPC.jpg) to only show the firmware date and version number, and it did not display the temperatures for the nozzle and bed.

I double checked and triple checked the wiring to ensure nothing was loose, and there were no issues that I could find.

The RAMBo Board's LEDs (http://i.imgur.com/5WZ0V8K.jpg) are lighting up such that two are solid red, one is solid green, but next to the solid green is one rapidly flashing orange. I looked around and couldn't find any documentation on what this means.

What steps am I able to take in order to resolve this problem? Is there any way I can try to format the RAMBo to re-upload the firmware? At the current moment when I try to upload the firmware again it is giving me a timeout error.

Please let me know, thanks!

Does anything happen when you turn the knob?

g.

Yes I had tried turning the knob, clicking the knob, and pressing the reset button. Nothing happened.

Check your hotend connections at both ends. If the I2C isn't able to initialize, that'll prevent it from booting up the whole way. Make sure the wires in your hotend whip match the diagram (I once put them in with the connector upsidedown and the order was backwards) and check your wiring to the RAMBO.

I'll go through all of the connections now and let you know what happens. Hopefully this is the solution.

I removed the hotend from the arms, inspected it, and since everything looked spot on, I put it back in place. I checked the wiring for the hotend whip and the wiring to the RAMBo, but everything looks fine. I removed some of the connectors to unscrew the wires to put them back in, but it didn't seem to change anything. Is there any way I can use a voltmeter or something of the sort to test to see if my wiring is good or not?

Do you know of any other issues that would prevent the RAMBo from booting up the whole way?

Thank you for your help.

you can always check to see if some wire is shorted to ground or a neighbor wire since we don't have access to a schematic for voltage outputs

Thank you for your help.

The hot end fan should come on with power up as well as blue LEDs on the hot end. If that does not happen then you don't have power to it correctly.
Otherwise use a volt ohm meter to check the continuity of all the wiring to the hot end. Use the ohms setting on the meter and expect good connection to display less than 5 ohms.

I did find the source of the issue... uh how does one go about removing the plug-in wires from the 8-pin terminal at the end of the wire whip?

(At the end of the day, the issue is all my fault for being a little over eager and careless.)

A major plus of open source hardware is that information is available. Which schematic were you looking for?

I stand corrected! You have made a technician's day happy

What was the solution to your issue in this case Chris?
