Hi,

Added Z probe types 7 (switch connected to Z endstop) and 8 (as type 5 without any filtering, for faster response)
Bltouch or Míni Differential Ir Sensor, are affected?

Hi,

Bltouch or Míni Differential Ir Sensor, are affected?

IR sensor: not affected if you use it in analogue mode as recommended for the Duet. But you could use it in digital mode with the probe type set to 8 if you wish.

BLTouch: if you currently have the probe type set to 5, you could try 8. It might give you slightly more reproducible results.

Here is what the new mode is about. The ADC on the Duets reads every enabled input channel once every millisecond and feeds the values into averaging filters. When you use a digital output Z probe, the ADC is not used but the Z probe is still sampled every millisecond and fed into an averaging filter. This can be useful for debouncing and rejecting glitches. However, it means that there is a variable delay of up to 1ms before the Z probe signal is recognised. If you are probing at 1000mm/minute (as we suggest with the Smart Effector), then the head will move 16.7um in 1ms. So the 1ms sampling introduces an uncertainty in the trigger point of +/- 8.3um. This uncertainty is avoided when you use mode 8. At lower probing speeds, the uncertainty is lower.

DjDemonD

What debounce value would you suggest in G31 for smart effector? Or does this not apply when using p8?

dc42

Debounce doesn't apply when using P8. Any value between 1 and 1000 should give the same result.

Hi David

On Scara I have a strange problem with
DuetWiFiFirmware-1.20beta10.bin
I have shifts of layers in x / y it does not get well
unusable ….downgrade
DuetWiFiFirmware-1.20beta8+1.bin
DuetWiFiServer-1.20b8.bin
result ok ...
sorry brooken English ...

I also have experienced layer "skewing" with 1.20beta10. Printed a gear bearing from Thingiverse and it came out slanted, but more on one side. Strange effect.

frafa

yes it's strange about simple shapes square/circles it works
while on complex shapes it does not work anymore …

DjDemonD

Hmm it seems something odd is going on. Last night I set a tray of parts printing and this morning there was a completed tray but with a nasty layer shift (never seen this happen on this printer before). Assuming it was because I was messing about with probing and might have lowered my motor currents and did not put them back, I started the print again today, same issue despite running all motors at 1.2A/1.68A.

I will try again but on a different firmware version, I need to get these parts printed.
M122 if it helps: https://1drv.ms/t/s!Apv79JfGbPIwg4QskvIqENNjz_mSWA

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 0.000

seems like there are a lot of step errors for 3 layers

franzelka

Something is definitely odd with this firmware release.
First image 1.20beta10, totally messed up. Second one 1.20beta8, all going well until now!

DjDemonD

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?

dc42

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.

franzelka

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 problems

It seems that after finishing the two solid layers every new layer gets skewed. With 1.20beta8 I could finish the print without any problems.

dc42

Thanks, I'll try printing that on my delta. Please share your config.g file.

whosrdaddy

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.)
Delta

Firmware 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: 1.19.3

Took 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.

dc42

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.
