ATOM 3D Printer Group 造訪社團 » CES

That happen to me a month ago and it will get worst to a time will say
“ERROR: MAXTEMP”.

I did my research and I obviously asked Atom support. Here are the first thing to do...
1. Check connection
2. Check if “heat-disc” is damaged And check the wiring for any crimp or little cuts.
3. Check connection in board. Unplug and check if solder is damaged, even behind the board must check for damaged solder.
4. If all of above has been done and still no luck. You may need to change the thermal resistor in the cooler block or the heat disc. And wrap it some kapton tape around the cooler block to prevent heat escape.
Good luck!

I was touching the wires above the fans and one was very hot. When I lifted them, the temperature started to rise and it worked! It seems the wires must have been blocking the airflow, and not letting it heat the last 5 degrees
Repositioning the wires got it started!

Thanks!

Try to use your finger to stop the back fan first.
If the temp can sucessfully reach to 210 degree C after the fan stops, please use PTFE tape to wrap the nozzle.
It can prevent the Thermistor from the fan air.

it should be able to fix the problem.

Thanks!

Amazing works!

What is better about the duet board? Does it have better stepper drivers?

Birk Binnard live firmware updates, better drivers, web interface. A lot more expansion. More importantly it's a 32-bit board which gives you better performance on calculating delta kinematics in comparison to the 8-bit board.

I'm in the process of doing the same, but I'm replacing the effector with a smart effector and an E3D V6. The Atom never printer properly for me, the filament always got clogged at some point. Now I'm finally able to source parts in North America, which is a big relief.

Yes, nozzle clogs seem to be the great nemesis of the Atom design. I tried using a Mini hotend but that got clogged too and there's no way to torch it without pretty much destroying it. So I went back to one of the beta nozzles used during the 2.5 EX d evelopment process.

I put a longer PTFE tube in it that comes very close to meeting the end of the external PTFE tube from the extruder. That seems to make a big difference. I also put connectors on all the wires coming out of the end effector so I can switch without having to re-string everything through the Bowden wrapper.

I would be really interested in what you come up with. Let me know if you need help, because I am wanting to switch to an all metal hot end too. You might want to look at a Zesty Nimble as an extruder too.

The joined PTFE should come pretty much flush with the one going into the nozzle. I know I had to swap out what ever was in there for are 35mm one or something.

I got the printer running, but it's in an intermediate state where I need to print some more pieces to work properly. The V6 is a major change, I don't have any of the issues I had with the Atom effector (ie. Low flow and extruder jamming). The main th ing at the moment is recalibration as the geometry is different with the smart effector. I'm now trying to mount the smart effector on top of the Atom effector platform, it seems like it might work. I'll keep you posted. I also have a Titan extruder that I intend to mount, I'm currently using a first gen Dyze Extruder, as I had issues with the Atom extruder.

Word of warning, PTFE is all the same. Going hotter than 260 will start off gas, even thr capricorn tubes. They just take longer to degrade.

Would the duet work for the Atom 2.0?

Yinka Alade yeah, no reason it shouldn't work. You do have to do some degree of rewiring and recrimping, but it's not something too difficult.

I'm on the way to switch my motherboard to Duet2 Wifi. I have the Duet board, but not the screen touch for the moment.

I'd be happy to help anyway I can if you have questions or issues. I love the Duet, and it was a fun upgrade to do.

check Button line use Electric meter and motherboard hole maybe just with ease

Reloading firmware did not help. I swapped stepper controller circuit boards between 2nd extruder (which I know works but don't use) and Z stepper - no change in behavior.

Found problem II hope) : Motherboard is not getting signal from Z-Min endstop. Must have broken wire someplace.

Shouldn’t the end stop it be plugged into the Z Max socket on the Atom board?

Yes, and it is. But I've unplugged both wires from the motherboard and connected them to a multimeter. The meter reads nothing when the end stop is depressed. So either the end stop itself is bad or there's a broken wire somewhere.

What' confusing to me is why that kind of problem would produce the results shown in the video. I would guess the Z-axis would just crash into the top of the rail and keep trying to go up. But this is not what happens at all.

I hooked up an extra switch to the Z-Max motherboard connectors using it's own wires. It works OK. So it's either the original switch or the wires between it and the motherboard that is bad. I'll try using this switch on the Z columns to see if that fixes the Home issue.

The new switch and wires work OK. Now I have to figure out if the original problem is bad wiring or a bad switch.

If the switch is wired NC (normally closed) that is exactly the behavior you should get. That prevents the motor from moving up in a homing situation. I.e if a wire or the switch is broken with a NC setup the motor won’t smash against the top of the printer and potentially damage it. If you have a Normally Open system with a broken wire the system won’t know either way and would hit the end of travel.

Atom doesn't tell us if the switches are NC or NO. My guess is NO. But in either case I still have to figure out if it's the switch or wiring that's bad. I'm hoping it's the switch because I don't think it's possible to replace the wiring without disassembling 1/3 of the printer.

you can try to
Restore memory & run Auto calibration & auto level

Surprisingly the problem was a bad micro-switch. This was fortuitous because I was able to use the existing wires. It was a bit tricky splicing in the leads from the new switch, but I was able to do it without breaking anything else.

是得沒錯剛剛試過了這樣就能跑了~~XD~~~
