I’ve been running cuts without any problems for months. This morning, my machine just started a serious problem, and I’m seeking some help. While cutting with nobody near the machine, the job stops. The display says this:
KILLED. :
PRINTER HALTED
Please Reset
Three jobs in a row. I’m ruining wood. I Just found the machine sitting idle - not even running a job and the display switched to the “killed” message.
What I’ve done so-far - Opened the display box and blew-out any dust. I removed the red button for halting jobs, just-in-case - then covered the hole with tape. No difference. It is still halting.
I think I found the problem. “Someone” did a really crappy job connecting the power with the jumpers. One of those jumpers fell out, and was making a very intermittent connection. I put in new jumpers, wetting (soldered) the ends this time. No more twist-connections. I have a 2 hour job running now, so time will tell.
The power connection is SOLID now, and all the other wiring seems to have good connections. Are there any logs that I can access that might reveal the problem?
I plugged-in with Repetier Host and see the log. Here is a complete log from power-up to failure. I never started a cutting job. Does that message indicate that the abort button was pressed, or the circuit otherwise closed?
The box is all wood, including the 7mm stand-offs. I even pulled the board out and ran it on my wooden workbench with the same results. Voltage is a steady 12.7. I don’t have an oscilloscope, so I can’t measure it over-time when the “halt” happens. I do notice though when I leave it without power for an extended period, it runs for a longer time without error - 10-15 mins. Once it “warms up”, it halts at every boot-up immediately.
I’ll let it warm-up and then test the voltage again. It could still be the power supply.
The voltage seemed to stay very steady at 12.73 through an incident. I have a 12vDC supply that I use for my 2M radio. I’ll wire that up and see if there’s any difference.
I get the same error with or without the USB plug. I normally cut from the SD card and don’t use the USB. I only connected the USB to determine the cause. To be sure, I just powered the board with the LCD connected, but the USB disconnected. 8 minutes in, and it halted. As @jeffeb3 noted, it says I pressed the “stop” button on the display controller - even when the ribbon cables aren’t connected to the RAMBo.
I’ve disconnected everything, including the USB and the display. The only connection is power. I’ll run it for 20 mins, then connect the USB to read the health. I did find that when Repetier connects, it will show the log history. This is to determine if it chokes with only power and nothing else.
When you connect to repetier is should reset the board. At least last time I checked.
418 is really old, I am not sure if it had any issues. Flash the current and see if it still happens.
I don;t think we have ever had a rambo go bad after it has proven to work. I think the worst we have seen is a 1-2 bad drivers (they were missing a resistor).
I’ll try the flash. I haven’t connected the dual end-stop switches yet (I need to order some connectors for extension wires). Which firmware should I use, considering it isn’t connected yet, but I want to use them in the near future?
