Since I upgraded the firmware to the latest, I have noticed that all of my prints, regardless of material, have the nozzle dragging across the print during infill.
I have switched from the 0.4mm Stainless Steel nozzle to the 0.4mm Hardened Steel nozzle, in case it was a hot-end issue and then recalibrated but I still have the problem.
I saw that some users were complaining about the problem on the A1 mini, and it cleared following a ‘Factory Reset’, so I performed a factory reset on my machine; however, it has made no difference
The filaments have been flow calibrated, and the parameters inserted from the manufacturer (PolyMaker), but it is still a problem.
Models that have been completely unmodified from before the firmware update are also having the issue.
Not had a chance to as I have to print stock, but will do ASAP.
My filament specs differed from those in the library (PolyLite Pro), hence the flow rate calibration (plus it found a possible bug).
What I have noticed is that the build plate I’ve been using is thinner than the BL standard, so I put the BL one back on, run a bed-level calibration and then run a print job. The top layer issues I had been having seem to have gone away, though the nozzle is dragging on the bed in the central area on the three layers (decreasingly with height) and only stops once the infill begins.
This has then opened questions for me…
Unless it is just checking to be ‘in range’, the bed levelling must build a topological map somewhere or it’s a pointless 15 minute exercise; however, the Gcode shown in the slicer is using absolute mode for Z. If there’s a map I would then expect the ‘absolute’ value be ‘relative’ to the map, BUT the slicer version of the Gcode doesn’t change the Z height throughout the layer.
It would be useful to see the bed levelling results.
No. I mean the bed levelling results… the ‘topological map’ that is produced after the bed levelling, as data. ie, what measurements were made at each point, and with reference to what.
In my experience the dragging is being caused by layer changes Height/seem usually as a result of travel speed of the printhead hitting the start of a layer before actually hopping both with infil and a cylindrical print , i have also taken the time to witness this happening, so i dont think its anything to do with levelling
i do beleave there is a bug in the slicing software all of this started after the last update .when they fixed the load pop at the top .on start up this is when i found it started a missing code in the gcode for it to lift but no its draggs
Just as clarification before you rollback my first experience was on A1 long before the last update and id go as far as to say if its not effecting the print by dislodging them, it would be safe to leave it as is ,but you must do what you feel is best
I was having the same problem actually I am having the same problem as well. Inside bamboo Studio I make sure that the independent support layer height is unchecked even if I’m not using support. That usually does makes a difference. However yesterday I noticed that my hot end was not far enough down so I have about half a millimeter or more space between a hot end and the plate
I have also been having the dragging issue. Stock stuff, that has been specifically designed for the A1 mini. It literally just started happening a few weeks ago (had my machine about 3 months… Even stuff I have printed in the past, cannot be printed. Literally a useless machine at the moment.
Try resetting the machine to factory settings and go through the setup process.
I think that somewhere the nozzle height is setting too low (also seen as first layer line width in the slicer). this causes clumping that is picked-up on subsequent lines.
Anyone still having the issue? Battled with it for a day and a half and managed to figure it out. I mean… at least i hope i did.
All of the sudden the my A1 mini started dragging on gyroid which was almost never the case. I do think I’m a “special case” as the 3 little bed screws under the heat bed were not tighten since the unboxing but about 3 weeks ago i did just that’s when the bed wouldn’t auto-level anymore and the issues started pouring in.
Manually trammed the bed about 3 times and just now i think i succeeded. After doing it the proper way, everything prints with absolutely no issues. 60% of the time works every time…
There is an occasional touch of the infill while travelling but i can definitely say that the issue is fixed.
Let me know if you need help with anything.
