oh well this thing wasnt going to win any beauty awards anyways :) ignore the nest of wiresAttachment 7470
I also have mine working and it has been printing for 4 hours with no issues.
I am happy to report printing with PID enabled and with the heat bed off I am getting the same results; in other words no banding.
I am having some problems since implementing the ssr. Not sure if it is that, or the new power supply. I suspect the power supply. Got the 79amp model linked earlier in the thread.
The he issue I am having is the print just stopping. I am running the prints from the sad card. It is like the printer is being momentarily reset. The print just stops and reverts to a state it enters when you first power up.
I havent witnessed this this first hand yet so I am just speculating. I had a few small prints work fine with the ssd before the new power supply was installed. This is why I am leaning towards the new supply being the culprit.
Poor tsteever, you just can't catch a break :O(Quote:

Thanks for the sympathy. He he. I probably cause more problems stumbling around then anything else. Things are much easier to diagnose when there is a pattern. This issue has no pattern I can see. Some print fine, some don't.
My last 8 hour print completed without issue. Looks pretty good. I'll keep printing away and see if I can notice a pattern. Also, the power supply I bought was linked to in a different thread. It is a bit overkill, 75 amp server supply relabeled as a Juice Box from Ebay. I will keep an Eye on it.
Print tonight failed. Gotta to figure this out! I checked all the wires and they look fine. Is there anything in the firmware or code that could cause this? Perhaps the power supply is the culprit.
Have you checked the voltage output?Quote:

I do not. That is a great idea. The times i have been present it has printed fine.
As a test I let the printer idle over night. I set the speed lower and it was the same in the morning. If the power had interrupted it would be 100%, which it was.

If the thermal runaway is enabled, that might be triggering it.
That isn't enable. Good thought though. I am going to switch back to my old power supply and see if I get the same problem.
Would you still recommend the solid state relay mod with a i3v 12" purchased today with the built in relay and aluminum heat bed mount? Does the new heat bed having a built in relay make this mod not possible?
Unless he is now shipping a bonded aluminum heat bed then yes I would still recommend it. By bonded aluminum heat bed I mean the heatbed itself is bonded to a piece of aluminum.
He mentions the relay is now built in. Would that mean I'd just have to rig it to be always closed and then add the solid state or should it still be possible to cut it out now. Never seen one in person yet so not quite sure what to expect.
Can you provide a good picture of the relay on the heat bed? If it is a mechanical relay, you'd have to either wire that relay so that it is energized all the time or jumper across the contacts for that relay. PID requires the use of a solid-state relay that can be switched on and off much faster than possible with a mechanical relay.Quote:

Has the relay you ordered continued to work well for you with just the heat sink to cool it?
I purchased the relay and heatsink posted here and have had zero problems. In fact, I haven't noticed my relay getting even remotely hot. That heatsink is huge!
Yes it has worked fine so far with the heatsink. It gets just slightly warm to the touch but not hot at all.

No problem,
It was a pretty frustrating experience but overall I am pretty happy with the performance of the printer now.
