1 is a year old and the other 2 are a few months old.
Recently I printed the same model on the older printer and then on the newer printer and got slight different quality results. (Same model, same filament, same profile, same everything)
The newer printer seemed to print it better (less layer lines on the first layer)
Before I go to deep down this path - I’d like to know if there is a good TEST model to use that I can print on both - that can possibly provide an indication if something is wrong.
I am thinking these filament swatches might be good:
Problem with test/calibration models is that if you want one that includes everything printing takes a lot of time and filament.
There is quite few on Thingiverse for example that you could try if you really wanted to.
But do you have to ?
Two printers doing it fine, one does not and all machines use the same firmware, slicer and filament.
Age and wear & tear comes to mind here.
There is those carbon rails and their ‘bearings’ in the print head for example.
Or the belts and pulleys that might need some adjusting.
But the one thing many users never consider is the nozzle itself.
These things are consumables because the constant extrusion of filament causes wear, causes the nozzle diameter to increase and the hole to become messy.
Assuming your old x1 never got any new parts do the most basic check first before going into a possibly deep rabbit hole here >
Just swap the hotends
If then the new X1 prints bad while the old prints fine or much better you know you need a new hotend (maybe updgrade to an E3D?).
In case nothing changes for the old printer you know the issue is most likely hardware related on the machine itself.
So nice to have multiple machines at hand to a quick swap testing…
