printer is disconnected

Hey fellow upers

I have a disturbing problem with my printer.

Was printing a bracelet, print started to lift badly (doesn't happen often if alt all), so I had to stop the print 'mid print'.
Waited for things to cool.
Now up software says that 'printer is disconnected' when it is connected, and I cannot access the maintenance screen. Looked in the device manager, could not even find the printer to reinstall the drivers.

When I received this up the motherboard had to be replaced to get the platform to heat up.

Can anyone help me? Would rather be printing...

Sounds to me like the CPU is fried. Are you still under warranty?

[*]Yeah it is still under warranty.
Utterly disappointing, I've already had to do main board surgery on it a couple days after I got it, I haven't even printed that much on it.

It prints nice, happy - but dud out of the box, and now this a couple months later.

Suppose I'll put a support ticket in .....again

All other advice is welcome

After leaving it several hours and trying a some sort of result, I try one more time before considering that I may have a blown chip. It would seem that the up's tantrum has subsided for now,, let's see if it will print something?

Just tried to print something and although it started to put down a plastic raft this quickly ended, noticed when the sticker on the side of the spool stopped turning round. So now have to figure out why its not extruding, yay?

Try unplugging power to the printer to reset. Go into maintenance menu and withdraw filament. Then select extrude. Try to print again, this usually works for me.
If this doesn't work, than you probably have a clogged nozzle and will need to be cleaned.

I am an Afinia owner and I recently had a similar issue where I had to abort printing due to excessive warping of the print causing the extruder head to strike the print, and upon trying to initialize the printer I got the same dreaded "printer is disconnected" error. I tried reinstalling drivers, reinstalling different versions of the slicer software (both Afinia and UP with no luck). Ended up having to RMA the part and lo and behold I was told the CPU was fried and needed to be swapped out. The printer is back now and running beautifully, however, I am extremely worried that this issue can happen again at any time (especially worried as the warranty is almost up), and I would love to get anyone's insight on how to prevent this kind of fatal failure mode from occurring again.

It seems like a majority of people reporting this issue have concluded that the root cause is ESD damage related. I've also heard theories of a power spike caused by excess power to drive the motor when the extruder head strikes the print or printing surface (is that even possible?). I've also read of the height sensor cable (?) being faulty. Is the general consensus still ESD and is the only way to avoid this to go all out with anti static protection? I actually hope that this is the root cause as I can go about proactively preventing it from happening again.

Also, can anyone confirm whether the Afinia H-series is an UP Plus or UP Plus 2 in terms of hardware? I heard that it is the former, which leads me to assume ESD has just always been a risk factor for UP Printers.

I get the printer is disconnected on the software all the time when its running in the background

I just close the software and unplug the USB cord and replug and rerun the SW and its fine but i would loose the initial build picture of the part.

I have to open and close my software a few times to get it to allow me to auto level... or I must unplug the usb, turn of printer, unplug printer, leave it all off for a minute or so then plug everything back in to get it to let me autolevel..

I am assuming the software is like the hardware.. NQR... :roll:

If you're using it on a Mac this sounds about right, on Windows you shouldn't be having that much trouble. Try leaving it plugged and use the hardware switch to reinitialise.

On windows.

I have tried that too.. doesnt work.

another odd thing it does is now and then if I preheat table it gets to about 90c then starts cooling down, but still says heating.. only way to get to to carry on heating till 100c is to go into maintenance and stop heating, then restart it...
