I don't own one but looks like it can be becurse the bed is not level have you tryed a ned levering of the grid

Remove the spring when you do bed leveling, and assembled it back after bed leveling.

I didn't had this before and the bed or the glass plate can't be placed in another way. For the spring, I don't think that the spring doesn't do its work, it is as the steppers don't move in equilibrium to each other. Can the voltage change on the drivers of the steppers. I once calibrated them to 0,4V because they had a different tension each.

Please try to remove this spring first, then do the bed leveling again, this is main reason what cause atom nozzle error move, I had experienced before and it is not happened only on me, but also many atom owners, so do it and see what will it happens!

Hi Marx, why is Atom not redesign it without the spring? I should have done it in another way, because the sheet metal part on the head is being deformed by the executed pressure on the nozzle. I think that this is also the reason why the leveling is c hanging each time. It should be constant, but with this design it isn't possible. Deformation is a real fact, also the pressure isn't the same allover the bed. This point and each point next to the guides are very strong in pressure.

How wut you rate the atom martial is it worth the many money? Becurse I am consetering one becurse I am tired of problems with the real cheap printers on ebay my printer now is little monster and hate it so many problems

Hey Martial Geudin, to be honest this is old problem in Atom 2.5EX version, and I don't know why they let this exists till now, you can try searching " bed leveling " in group, it will shows tons of same issues with your situation now.
It was a good machine and good group here, but now a lot different.

Oki Marx wu soo you think ? wait to new versions?

to be honest, no machine is really good, we are dealing with a new technology, even it is 25 years old. many have tried to make something better, but still running into the same problems. You need a good industrial designer to analyze and improve this techniques. I am following this domain since the beginning, good machines are expensive and still having issues. So there is a lot potential in this market but with lots of competences. And we have to learn from what was already made to improve and build on it.

My old Atom 2 was and still is a fantastic machine! I bought 2 AtomEx2.5's and have had nothing but problems with bed levelling issues etc. Both my AtomEx 2.5's have the exact same problems including other random issues like print shifting half way th rough a large print for no apparent reason. My old custom built prusa and a couple of modded Makerbot2's also never fail me even after several years of constant use doing full volume print after print. So yes there are good machines in my experience.... But everyones mileage varies I guess.

How is support on it then? On the printers and spare parts? Thanks again

Per Andersen As Sean Thompson said, atom 2.5EX is a fantastic machine, reasonable price, I had have it from Version 2, and ungraded to 2.5EX except the bed leveling problem I had, not to much problem happened.

It was good enough but it didn't move on since version 2.5FX, it has been a while...
