Welcome to the SeeMeCNC Community

Hello,

I am having a serious problem where my printer will literally reset itself during a print! I have tried unsuccessfully to print an object 3 times, each time the printer resets itself and stops. It's the same action as when you press the red reset button, only it's a ghost doing it Can someone offer any advice?

Thank-you!

Forgot to mention that I am running through a SD card and using Simplify3d if that makes any difference.

You likely have a loose connection somewhere - with the connector on the HE280 being a prime suspect. Or, static charge maybe? I have a printer with a RAMBo (Lulzbot) that is very static sensitive. I ended up running a ground wire from its frame to the outlet's ground post and the issue went away.

Oh, and yes, Simplify 3D will cause all sorts of inexplicable problems.

Spoiler:

Note: this was sarcasm based on my visceral dislike of S3D, its archaic licensing and the company behind it.

I read somewhere that it could be the sd card? Simplify3d has been ok so far

Sometimes SD cards can cause problems. Do you have another card to try and eliminate that as a suspect?

I do and I'm going to try that now. So you grounded your rambo Frame? How did you do that? I read that you grounded it to the ground on the plug, but where do you ground on the board? Or were you talking about running a ground from the actual metal tower frame pole to the ground on the power outlet? Sorry, I'm not an electrical engineer. Although, after a year or two doing this everyday, I might just pursue that as a career

No, I grounded the aluminum extrusion frame on my Taz 4 printer. Simply screwed a wire to it and ran it to an outlet where I grounded it in the ground hole. You don't ground the board itself, just the printer's frame.

Just tried a new SD card and the LCD screen just went blank the second I inserted it. It must be something with the RAMBO, right?

Oh, ok. That makes sense. I'll do that today. Thank-you!

It might not help, check the SD card first. And check for loose connections.

Or wiring.

Checked all the wiring ...again and everything looks fine. I inserted a new SD card and am printing now. I found that simply just restarting (shutting off and back on) the printer, the LCD would turn on just fine with the SD card already inserted. Hopefully it doesn't reset during THIS print. I'll definitely loose money on this print as it's my fourth attempt and almost a full spool into it.

I had a similar problem and noticed that the positive and negative going to the new hotend was switched. Try checking the pinout of the connector with this sheet https://d17kynu4zpq5hy.cloudfront.net/i ... qZBLO.huge

The thing is, is that I was printing fine for quite some time (at least a month) and then all of the sudden, it just resets itself during the last 3 prints. I did check the wires, but they didn't move themselves and are in the correct position. I was hoping that would be it though. Thank-you for your input, but I'll keep trying.

Just reset again! I was here to watch it this time and it happened when the printer was printing the infill, not that that makes a difference. It literally just resets itself. I swear, I have not had any luck with this machine. Can any of you offer up any other suggestions?

Maybe your PSU hickups (or even your mains...). Try to monitor the power served by the PSU, if that dips around the time of a reset, that's probably it. I had the same issue, but it wasn't resetting, it was shutting down completely. I RMA'd the PSU and the second one I got works just fine. I do not think it is a Rambo thing (yet).

I've had an issue that was similar, where it was the physical reset button on the rambo slowly degrading despite not being pressed. I hesitate to mention it, as it's an isolated issue from what I know, and it's just an utterly bugnuts one. However, I would see if the reset switch seems to click properly on the board. If not, contact Ultimachine/seeme for a replacement or repair, or if you are rather confident, desolder it (I do not recommend this, as it will likely void any warranty from Seeme or Ultimachine)

...or simply disconnect the LCD entirely and print via USB.

g.

I flashed it with the newest firmware and it's been printing great (minus stringy prints and blobbing, but at least it still on).
