New beta firmware release 1.20beta10
-
I had the same issue with the skew.
=== Move ===
MaxReps: 130, StepErrors: 123, FreeDm: 240, MinFreeDm 120, MaxWait: 2228747316ms, Underruns: 0, 0
Scheduled moves: 2721, completed moves: 2721
Bed compensation in use: mesh
Bed probe heights: 0.000 0.000 0.000 0.000 0.000seems like there are a lot of step errors for 3 layers
-
Something is definitely odd with this firmware release.
First image 1.20beta10, totally messed up. Second one 1.20beta8, all going well until now! -
Mine wasn't as dramatic just a nasty layer shift towards -y (on a delta)
But those were 2 of 16 parts on the build plate, and then I reproduced the same error on the next 16, but cancelled the print as soon as it happened.
Interestingly I'm running the same FW on my corexy no issues so far, is this a delta problem?
-
Please can those of you who have experienced a layer shift using the latest release do the following:
1. State what machine architecture you are using (Cartesian, Delta etc.)
2. If you have a model that reproduces the issue easily, post a link to it
3. If possible, with 1.20beta10 loaded, connect a PC via USB, and send M111 S1 P4. Then print the model. Each time a step error is recorded, debugging info will be reported via USB. Post 50 or so lines of that debug info in this thread.

1. Delta (Kossel Mini T3DP3D)
2. https://www.thingiverse.com/thing:2323213/#files -> Apple-Watch-Phone-Stand_V7.0.stl
3. there are no lost steps. No debugging output from USB logging and M122 didn't show any problemsIt seems that after finishing the two solid layers every new layer gets skewed. With 1.20beta8 I could finish the print without any problems.
-
Thanks, I'll try printing that on my delta. Please share your config.g file.
-
I'm running beta 10 on a cartesian, no problems to report.
Seems to be a delta/scara kinematics problem… -
Hi,
#1 Delta
#2 Benchy : https://www.thingiverse.com/thing:763622
#3 no bug reported
Additional notes : the bug is not consistent, it's not happening each time at the same place with the same gcode file. In my case on 4 benchy, it happens 3 times and each time this "offset" was temporary (see picture)

Hi David,
1. State what machine architecture you are using (Cartesian, Delta etc.)
DeltaFirmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20beta10 (2017-11-23)
WiFi Server Version: 1.20b10
Web Interface Version: 1.19.3Took two attempts to load wifiserver via sd card. I am not getting as far as being able to get to the point of the layer shift. First attempt the machine threw a heater fault (normally completely reliable) just after warmup and delta calibration so i restarted it. The console debugging is in this file
https://1drv.ms/u/s!Apv79JfGbPIwg4RptjqtFRPVBjLS6w
labelled console.txt.
Then I tried again, and it crashed, stopped printing at around layer 8 nozzle on the print, nothing for a few seconds then a full reset. I powered back up saved m122, and have included console (console2.txt), eventlog and config.g.
Hope this helps but I'm downgrading for now.
-
Thanks. Unfortunately the M122 file is empty. However, I see some extruder step error reports in one of the console logs and I will take a detailed look at those. The full reset sounds as if it may be a watchdog timeout, which one other user has reported getting in beta 7 and later.

Sorry about the m122. I will reduce extruder steps/mm which is quite high on 1/16th with Nimble 1/8th or 1/4 would work just fine.
-
btw I simulated the high E steps/mm on my delta by configuring and selecting a dummy extruder, and I still wasn't able to get any step errors. So I'll take a look at your config and see what's different.
-
on scara I use
M82 ;Set extruder to absolute mode
can be bug come from there?
I can not test until Tuesday … -
Just to report I have had no luck getting wifiserver1.20beta10 onto my other machine a corexy, the only difference here is its a 1.02 board. Tried via the memory card several times, normal console messages installing etc but get failed to initialise wifi module, code -10. I did check I was using the updated file, not the first one which didn't work. Beta 9 wifi server working perfectly, however.
-
I have the same layer shift problem with beta10
-
I also have layer shift on my cartesian printer with external drivers. My stepper/driver has encoder that will generate fault signal if there is a large positional error. I did not get any fault from my driver which means there must be some thing wrong with the input signal they are receiving.

printed 3 benchy, with 3 layer offset (different on each print) nothing in step error through a M122
-
I'm running beta 10 on a cartesian, no problems to report.
Seems to be a delta/scara kinematics problem…I had the issue on my Cartesian printer. I have since restored to the previous firmware and it is fine now. I just pulled off the whole y-axis to do some tweaking so I cant pull up anymore info.
I sliced using S3d.
-
It looks like these issues may be due to a lack of free RAM in beta 10. I've prepared a new version with some RAM freed up. I hope to release it tonight or tomorrow.
