I’ve been using my X1C for a couple of months now and it’s been working amazingly well. Bambu Studio keeps prompting me to upgrade to 01.07.04.52 and the X1C wants to upgrade too.
It looks like the firmware bugs thread has stalled out, with no more input for several days. Should I update or are there killer bugs that are show-stoppers? I’m printing, mostly, TPA, TPU, and ASA on the PEI textured plate and I know the new firmware has some features that directly affect that.
No recommendation here , but i did update it and after update did recalibration and no problems seen so far with ABS, i print mostly ABS, ASA sometimes PETG , but since the upgrade been printing only ABS
First time i did upgrade had issues and reverted back from the mobile app , then i found out that recalibrating after install was solving my issues and since upgraded twice
Note i use almost exclusively Orca slicer, Bambu studio latest release still missing calibration features or nor well organized
I updated yesterday and so far works as it did before, just had to make sure I selected the correct hot end, it was set for 0.2mm whereas before was 0.4mm, and plate reset to Cool whereas i was using the high temp plate, apart from that all tickety boo
The rule for FW (or software for that matter) is generally “if it ain’t broke, don’t fix it”. If you’re happy with how your machine is running and you don’t need any of the features introduced in the newer FW and App revisions, then stick with what you’ve got.
If you do update, read the Wiki so you understand what new things you might need to do. Just my opinion, but I think many of the people who had issues after updating didn’t read the instructions. I updated no problem because I followed the instructions.
I bit the bullet and upgraded both the X1C firmware and Bambu Studio. I’ve printed with several different filaments since doing the upgrades and calibrating both the printer and the filaments (using the Cool/Engineering plate).
Today, I printed some Matterhackers Build PLA on the Textured PEI plate and got the following warning on the LCD screen:
“Filament exposure metering failed because laser reflection is too weak on this material. First layer inspection may be inaccurate [0c00 0300 0002 0001 1349 25]”
I’ve printed dozens of models with this filament before and this is the first time I’ve seen this (or any) error message. I wonder if my additional LED lights are causing this problem?
With textured PEI the auto flow calibration does not work , check with the wiki
Also the first layer inspection may not work always and especially with some filament colors
It needs to be off, but then you need to make sure that it has been calibrated either on different plate with auto or just set in the filament
Also cleaning the laser and recalibrate may help , but still will not work well on textured PEI and very often fails
For the above reasons and plate adhesion problems i stopped using the textured plate only very rarely
Thanks for your response. However, the error message seems to have nothing to do with first-layer inspection or auto-flow calibration. The error is message is about the X1C’s camera and its inability to set the auto-exposure based on the reflectivity of the filament used.
Regardless, I’ve not seen the message before, or since this one instance, even when printing the same filament on the same plate.
As I said before, all the filaments have been calibrated using the cool plate. When I print on the PEI Textured plate, I disable auto-flow calibration.
The message is not related to X1C camera! Actually the lidar is used for both, for auto-calibration and first layer inspection. The message is a bit confusing as Lidar acts as a camera and also has lenses
But worth cleaning both the side camera and the Lidar system ( laser and lenses) . Filament exposure means that still is trying to use it . And Laser is reflected from the surface
The message is not related to the side X1C camera
So for some reason is still trying to use the Laser( LIDAR), may be in start print by default the flow is on and was not turned off. Or first layer inspection is on
Not sure the AI does it use the laser or the side camera may be worth turning it off as well
K factor i use orca slicer as i found it very confusing and impossible , and do not ever use autocalibration only manual. The new Studio has a feature to do the K manually , but find it no good
@jyunte one more thing after a few days of no problem printing with the latest firmware using ABS
i Started using again eASA over the weekend, which was tunned and was working before no problems at all
Now have some issues , all flow and K values were different and if i print big parts have some spaghetti and respectively the print fails after around 70mm height - varies - But there was no problem before the upgrade and the same material . I cleaned everything, dried again , checked everything and still the same on 3 consecutive prints .
I found from a different thread that some one had issues , and did a factory reset , and then his problems went away
Doing it now , and new flow/K measurement, but if that does not work will revert the firmware as the eASA is the filament i use most on X1C , may try one more new roll before that
Yes… as stated several times already, I have used the Cool/Engineering plate to do the calibration and flow control and turned them off for the Textured PEI plate.
BL have stated that flow calibration, LiDAR doesn’t work on textured plates including their golden one. So if you want to calibrate then I suggest non texture plate that came with your printer. Then switch over once calibration has completed. ABL once you switch plates though.
If you look at the calibration patterns the LIDAR is “looking” at, it’s clear that it is looking at smooth versus bumpy flow. It should not be a surprise that adding the bumps of a textured plate would confuse the reading.
My results : After factory reset my problems are gone with eASA and the latest firmware suggested in another thread . Inconclusive if was the reset or the extra 20hours drying
But also my PETG prints with out issues i was seeing small extrusion problem with the latest firmware before the factory reset , now is gone , not calibration values changed .
@jyunte yo iterate the procedure with calibrating on one plate and then using another is not great
Also i have done a few autocalibrations and that is with dark color(black or dark green) and get inconsistent results every time with variations easy of 6% , Bambu states 10% variation some times. Variation more than 1%(some filaments 0.5%) on flow affects the print a lot , variation more than 4% (2-3% on some filaments) on the K affects the print as well ( from my testing)
But what ever works for you just sharing my experience , hope you are able to fix the laser error which is causing first laser inspection to be inaccurate “Filament exposure metering failed because laser reflection is too weak on this material. First layer inspection may be inaccurate [0c00 0300 0002 0001 1349 25]” - which is normal for textured PEI with some materials
That is why i suggested to turn off the first layer inspection in the previous post additional to turning off autoflow (K)
yes. always update. as a matter of fact, running the betas has been great for me too. Bambu is iterating and improving with each release. Keeping yourself on older versions is only gimping yourself.
