try replace your thermistor

I was about I replace the terminator when suddenly I found that one of the wire was bend and whimsy. So I solder it again.
I’m back in printig

It’s for my atom 2.0

If u need a lot I can ship to u, but I only have 1.7Ω (80W) and 6.4Ω (22W). It may need at least 7 days to delivery

Hi sir
Our heater is US$12 /pcs (not including shipping fee)

Hello sir
You can e-mail to support@atom3dp.com
We will reply you as soon as possible.

Any support will appreciate,thank U

That is an unusual problem for sure. It could be a bad thermistor or heater disc, or an intermittent wire connection for either of those. If it were me I'd take the hotend apart and check both of those parts. Maybe one will look bad. If both look ok I'd replace the thermistor first, and if that doesn't fix the problem then replace the heater disk. If the problem still persists check the wiring.

Birk Binnard will do, thanks.
I have one heat disc available if needed.

Actually, when I bought my Atom2.0, I also bought 2 extra set of extruder complete set.
I replace the whole extruder and see if anything change of the problem but still see the heat extruder flactuating.
This really worries me as I really don’t know what else to do.
I don’t want to touch any PID manually coz I may ruined more. Or should I do the failsafe and install the marlin again?

The temperature reading should be steady as a rock. It should increase and decrease at a steady rate. When it has reached the temperature you specify it should not vary more than 1 or 2 degrees.

When you first turn the printer on the temp should read room temperature, because that's what it is. If that varies then you have a wiring or thermistor problem.problem. When you turn on the heater, if the temperature reading varies you may have a problem with the heater disk or it's wiring.

I replaced with a new ceramic disc and new thermistor, and check all connections all the way to the board.
Still doing the same problem.
Is there something else did I missed?

You know that thin metal U shaped thing that goes into the hotend assembly? Is that in there? If not, it’ll never reach the full temp as that blocks the fan as well as holds wires in place.

It has on it. I even wrap the hot end of kapton tape to sealed the heat.
Recheck all connections of all wires and still the same

hmmm, no clue then. My Atom though doesn't get 220 consistently either, but I typically print in PLA at 195

I can Pre heat up 200 or 240, but my settings to print is 210 degrees and it never reach just fluctuating.
Hate to garbage this machine, an expensive printer

Joe Abaquin Bing Aquino Trust, I've been having issues with this printer since I bought it 3+ years ago. I understand your frustration. It's weird that it'll preheat to that temp, but not hold that temp for a print. I assume you've already tried reinstall the firmware and all of that. That's a weird issue I haven't encountered yet and I've run into MANY with this printer.

Joe Abaquin Bing Aquino Please don't feel that way, you can e-mail your question to support@atom3dp.com , our engineer will help you as soon as possible!

ATOM 3D Printers
I emailed you again after the first response from Atom’s support. And waiting from your kind response, thank U!

Solved!
The problem was that my office is in the basement cold room and temperature was very cold.
My thermostat in my Atom detecting it and having hard time to adjust.
I am now printing again.
Funny thing is, my wife figure it out.

Please have this for a record for others when they have this same kind of problem

Gear look good

We recommend you change new one. Please sent the mail to info@atom3dp.com .

Will post and video if I see any faulty at the hot end.
Thanks guys

Do you hear the sound "click, "click", "click" when nothing comes out from extruder?

I check the extruder and find nothing wrong but the only thing I needed was the gear. The sales expert noticed that it was worn out badly and I will need to go with a metal gear.
Plus I found out that the PLA filaments (1kg) was not good (defect) and it was a soft filaments. The gear was eating it (clogging) and not pushing out more to the nozzle.

the right side gear will be fine, if still can't fix the clogging problem, change more soft spring

I just need to make the top and bottom thicker than the wall parameter.

ah.... here u r

Temperature -20 degrees, check your PLA extrusion

If u already use it a while.
I think u need replace the PTFE tube inside the nozzle first.
