ATOM 3D Printer Group 造訪社團 » 用戶發文

Well folks, it looks like I am unable to get my Atom2 working properly again. So I plan on replacing it sometime in the next couple of weeks. If anyone in Southern California would like to get my printer for spare parts I'm sure we can work out a fair deal.

It's been fun (mostly) while it lasted, but tomorrow I'll be assembling a new FLSUN QQ-S. So I'm dropping out of this group. ?

Which board to replace Atom2 motherboard? https://www.amazon.com/dp/B079GRJH6V/?coliid=IOK5PZSZ01706&colid=1CNC7HMGS7HXU&psc=1 https://www.amazon.com/dp/B07DFFNF1L/?coliid=I2QXEX8QOG284O&colid=1CNC7HMGS7HXU&psc=1 Both look like they could do the job. First one has no stepper drivers, but I have 2 Atom2 boards I can pull the drivers from. Second one has A4988 drivers on the motherboard which seems like a better idea. BOth are a different shape from the Atom board, so I'll have to drill some new mounting holes - not a big deal. 翻譯年糕

I’m waiting for Duet2 to upgrade my Atom2.5ex, also want to try the smart effector.

Why not switch to 32bits motherboard ?

Printer has gone crazy!

This short video shows what happens when I run AutoLevel. The same things happens at the same place when I run AutoCalibrate.

I've reloaded the Ver. 2018039 firmware with no problem. And yes, I did the Load Failsfe/Store Memory after uploading.

Could I have a bad stepper motor or stepper motor driver chip? There is nothing physically wrong with the printer, at least as far as I can see.

Is it actually the bed or no?

It looks like it thinks the printing bed is larger than it actually is

Birk Binnard

I've been printing on that exact same bed configuration for over a year. All of a sudden the printer seem to lose track of where Z equals 0 is. I have no idea what the problem actually is.

Yinka Alade
2019-10-02 03:27:39

Yea, no idea. I'd replace the motherboard and see what happens.

Birk Binnard
2019-10-02 04:01:07

I've had the same thought. Do you have any suggestion on which MB would be a good replacement? (Good = will run with vanilla Ta At om2 firmware.)

WOW really crazy @_@

If the touch sensor can work well, u may change the printing area by using smaller diameter, like 210 or 200 to c if it can work or not. …… 查看更多

Remove the spring during bed leveling

Birk Binnard

Since the AutoLevel completed OK (after removing the spring from the Z-Min adjuster screw) I thought I'd try Auto Calibration to see if that helped things at all. But that function crashed the hotend into the print bed on the 4th move. So there is still something wacked with the printer.

I wish I knew what it was.

Birk Binnard
2019-10-05 10:58:54

After a considerable time testing and checking I found 2 problems, one of which I was able to correct:
1. The small metal flap on the Z-Min micro switch was disconnected from the switch and stuck, by magnetic attraction, to the inside of the end effect …… 查看更多

Well there is definitely something wrong with the way the printer handles Z values. I used a different slicer (Craftware) and had similar issues with the printer's Z height when printing.

My layer height is set to 0.200 mm, but after printing the fir …… 查看更多

Thanks Clarence - I will try that. But I doubt I'll be able to make sense of the EEPROM data.

Birk Binnard
2019-10-07 12:32:30

OK - I tried that series of commands. They seemed to work OK. But printer still doesn't handle Z-Offset properly. When I do Adjust Offset the printer needs an adjustment of 1.350 mm to position the hotend at the proper height. After I do this the Z-Off …… 查看更多

How about check the belt, wheel etc. Might need to consider something loose in mechanical.

Birk Binnard
2019-10-07 13:13:28

Been there/Done that. All is OK.

Even if that were the case it wouldn't explain the Z-Offset values being so strange.

Clarence Lee

It's the farest edge, consider the cable might cause sensor not work as expect at the specific place. Try to loosen some signal cable length

Birk Binnard
2019-10-07 14:50:42

OK - thanks. I'll check all the stepper motor cable connections. That is something I had not thought about.

Nope - all the cable connections are OK - I checked both ends of each. I also made sure the stepper chips were all firmly set in their sockets - they were.
