I swapped RAMPS boards and everything started working. There must be a solder bridge or a bad component on my other RAMPS board. Strangely, the replacement RAMPS board does not pass through any power to the Arduino, whereas the other does. Granted these are a couple years apart in age, but I can't find any real difference between the two. Just means I'll be running this one tethered for now. Alsby Gyvven - RAMPS Electronics
I just created and uploaded a new firmware build for a diamond triple extruder (using the DiamondRepetierConfiguration.h file), but when I go to test it as soon as I apply 12v my Com port disappears, the arduino gets disconnected. I currently only have only the following connected: New extra stepper board - Aux 2 (44, 64, 59, 5v, gnd) and 12v, gnd near polyswitches. DRV8825 stepper drivers X axiby Gyvven - RAMPS Electronics
Ok, so I derped pretty hard last night. After I reloaded the firmware last night I imported the EEPROM settings and failed to notice in those settings the baudrate was changed to 250000, and I failed to make the change in the printer settings. I double checked it tonight and that was the issue. Again, all is better. Sorry.by Gyvven - Repetier
Out of curiosity, what does "wait" look like?by Gyvven - Repetier
Tried a reboot of the entire system, tried connecting, hit reset on control board, tried connecting again, nothing, again. I'm convinced there is an issue with the host software not wanting to talk to the firmware unless it's in the mood. The issue isn't in the firmware nor the hardware. I shouldn't have disconnected after that print, but I wanted to know if the connection was stable. I can't haby Gyvven - Repetier
Spoke too soon. After my print finished, and a lovely print it was, I clicked disconnect and tried reconnecting and I got the "1 command waiting" again.by Gyvven - Repetier
So, I don't know why it worked, but I flashed the original build of my firmware that was working a couple weeks ago (and suddenly stopped), rebooted everything... AND IT WORKS! I'm printing as I write this. Boy, am I glad that's over... knock wood, cross fingers. I really wish I knew what the issue was. This is a different board, so maybe I'll reload the firmware on the old board and see if it pby Gyvven - Repetier

I've rebuilt the firmware from the configurator with and without using any options, no watchdog and didn't even change steps. Still nothing. Hitting the reset button doesn't change anything in the log, it still says "no start signal detected - forcing start" without updating. I removed all windows updates going back to before I started having problems. And as I've said before, I've tried connectiby Gyvven - Repetier
Tried re-installing 0.95F, that didn't do it. Re-loaded firmware starting from scratch, re-installed RH 1.0.6, and again it worked for about 2 minutes, but then Z stopped responding.

I reflashed the firmware with the change for EEPROM from 1 to 2. It worked.... for about 2 minutes. I was able to home once, then I homed Z and the endstop LED didn't light up, and kept driving the hot end down, so I hit emergency stop. I was able to reconnect, did an M119 and all endstops reported L, I pressed the Z endstop and it reported H, even though the LED wasn't lit. I powered cycled everby Gyvven - Repetier
I forgot to mention, in one of my many attempts, it did actually connect but only for a few seconds before disconnecting. I didn't see any error codes in the log, that I recall.by Gyvven - Repetier
You may need to change the baud rate in your Repetier Host. Double check that it's set to the same rate you've uploaded to your firmware. If that's not it, what is or isn't happening when you try to connect?by Gyvven - Repetier
Last night I had a small problem that snowballed; My extruder stepper wasn't turning, though it was working the day before. I figured it's probably a loose connection, so I shut everything down, checked the plug at the RAMPS board. Still no extruder. Now here's where the fun begins; I decided I would try swapping out the stepper driver with a spare I had lying around. I plugged it in... err,by Gyvven - Repetier
So, on a whim I had exported my eeprom settings after I calibrated last time, I imported them and it seems to be working fine now. I don't know what the issue might have been, but it's fixed now. I'm going to open the config file and compare what I had uploaded with what seems to be working. I'm going to guess it's something to do with how I had the temp control set up, but that's just a guess. Iby Gyvven - Repetier
It just seems odd that it would be working fine one day and the next not. I know there was a windows update that occurred that day, so I tried going back to an old restore point, didn't help. I've also swapped out arduino boards. I don't have an LCD display hooked up at the moment, but I may have to try that. I tried heating the extruder from a fresh startup and that worked fine. I heated theby Gyvven - Repetier
I finished my new printer a month or so ago and have been happily printing away (number 3 in as many years). Then one day, for no apparent reason, after my HBP was heated and my extruder started heating everything froze solid. I couldn't kill it, I couldn't close the host program, I had to shut the printer power supply off in case of run away heating, and reboot the pc in order to stop it. A coupby Gyvven - Repetier
Here's a shot of one of the times the g-code sent the print head down to Y0 and then went back. Not sure what's up with the image link, but it doesn't seem to be working. Flickr imageby Gyvven - Repetier
I upgraded to 1.0.6 when I fired up Repetier and was given the notice that a newer version was available. However, when I was calibrating and bed leveling I tried printing the calibration cube and there would occasionally be a glitch that would send the extruder to 0 on the Y (sometimes less), it only happened once or twice in the first couple layers and then was ok, but it was extruding the wholby Gyvven - Repetier
I had this happen on my laptop; upgraded to 1.0.6, had some strange anomalies in my tool paths with both Slic3r and Cura, decided to go back to 0.95. I uninstalled and re-installed 0.95. Th splashscreen comes up and the I always get the error "The program has stopped working..." I've tried cleaning out the registry and re-installing and it won't take either version now.by Gyvven - Repetier
Found it. I had adjusted the First Layer Width and forgot to put the % back in. That still doesn't explain why it occasionally goes to Y-axis max or min. I don't recall seeing a checkbox during the update that allows me to keep my old settings. I have another computer with my old settings, I'll try and bring those over.by Gyvven - Repetier
A couple of things happened today; I had to mount new extruder gears and I got an update from Repetier that overwrote my previous settings for Slic3r (kicking myself for updating what was working perfectly). I was able to print a couple of test cubes, but when I went in to adjust the settings to what I was running before, IIRC, the slice would error out with " Invalid extrusion width (too large)by Gyvven - Repetier
I changed it back to bang bang but I'm only getting 1.1mV on the arduino D8. So, I think I'm not getting anything off the arduino itself.by Gyvven - RAMPS Electronics
I do have voltage at the 11A input and both sides of the fuse. PID is on, but no LED.by Gyvven - RAMPS Electronics
Just finished putting together a new printer and everything is working great except that I can't get the heated bed to power up. All connections are good but there's no power at the D8 connector. I've double checked my firmware to verify pin assignments. I'm thinking there may be something wrong with the board, bad solder joint or whatever. Any other ideas for things I can look at?

Charles, Thanks for the tips, I'll be trying those tonight when I get home. As for #4, I want my script to read "M340 P0 S1600" and then "M340 P0 S0" to extend the arm and then disable the servo and then do the same thing with the end script to retract and disable it, but I don't know how to add an extra line of script to the code.by Gyvven - Repetier
Thanks CBA. I've been noticing variations up to 0.2mm when I probe the same spot. I see some flex in the arm my probe is attached to so I might try printing a new sturdier arm. I also changed the Z_PROBE_REPITITIONS to 2, but I don't think it's helped. More specific questions about the use of this new thing: What is the best method of getting the Z-probe height to the nozzle? Where do I set Z0?by Gyvven - Repetier
I have my z-probe working but I'm unclear where to go from here. I can run a G32 S1 and it'll zip around and and take the measurements at the proper coordinates, but I don't know how to use this information or be able to get the distance to my bed accurately, nor how to print once I have the coordinates. The instructions for Z-probing on the Repetier site leave a lot to be desired. Has anyone donby Gyvven - Repetier
Sort of made some headway, swapped the RAMPS boards from the known bad Arduino and the Known good Arduino, everything works, even the Z-probe! Now to figure out what's wrong with the other RAMPS board, and finish calibrating the Z-probe.by Gyvven - Repetier
I had everything moving this morning, endstops working, was working on getting my z-probe working when I accidentally shorted the pwr and gnd on one of the endstops with a probe. I think I cooked the Arduino or my RAMPS board. Anyway, I have an identical RAMPS and Arduino that I had done the same firmware flash on, the only difference being the steps weren't calibrated.
