I am really trying here - and I have had mixed results with my X1C. Basically I am dealing with an issue where a print job will be successful one time and then the same print job will fail with poor adhesion.
It happens a lot! It’s like the measurements it is calculating are off. It is the same print job nothing changes. I even tried disabling bed leveling before the print only for it to fail the 3rd time.
This is a pic of the same test print I printed 3 times - where this one just broke from the plate and I see the head hovering printing spaghetti. As I type this I started the job over and now it is working again. Has anyone had this issue at all? If not - then if I have something wrong - I would like to know how to fix it or if they would replace it. I did open a support ticket but I am not expecting an answer for some time due to the CNY holiday and the current recall problem.
@mgtarallo, not enough information here to diagnose anything. So, in short, I’m sure you don’t have a lemon. Please share:
Filament type and age of filament
Print settings (whether default and/or any changes you have made)
Thanks for your reply - Just for reference, I am not new to 3D Printing - I have 4 Prusa MK3s printers and have been using them for 5 years with very little issues. I have torn them apart and rebuilt them and have maintained them as needed.
I am using a brand new roll of Overture PLA Black with default settings .40 nozzle .20 standard with a textured bed
Basically it just finished and printed fine - but previously it failed with the same settings. My issue is that if I go to print the same model again - it will sometime fail - with looks like a Z issue - I think it has something to do with the way it is calculating the z during bed leveling and the numbers are off and therefore is not low enough on the bed.
Might be that some small piece of fillament gets stuck underneath the nozzle (oozing, bad wipe etc.) and it can mess up the bed leveling / homing sequence…
Make sure that during the homing sequence the nozzle is clean.
I started the print all default settings and I hear it grinding away at the infill pieces everywhere - this cannot be normal. The Z is too low - we need to be able to adjust the Z index manually like every other printer out there.
Looks like the plastic is being pushed out too fast. What is the volumetric speed you are printing at?
and what filament is this?
Also, looks like you use rectilinear infil patern? Try using grid instead. Rectilinear prints a lot in mid air which might curl up and hit your nozzle.
I’m with Chris. I responded to your other thread on this same problem, so its best to only use one thread.
I thought this was either too fast for the filament, damp filament, or a combination of both.
Easy fix if correct, change the max volumetric speed to something slow like 10mm3. If it prints perfectly you need to use a better profile for the material. Other way to test is to simply put it in “Silent” print mode or speed. That will slow it down by 50% which is surely plenty to confirm.
If it is damp filament, you’ll see poor quality on everything you print with it regardless of the speed, but I’d imagine the slower the better still holds a little true, so you’ll likely still see a little improvement.
