@dc42 Thanks very much for this reply. I was not aware that there was any distinction with USB cables! The several that I had tried were all charging only. I kept trying cables until the Kindle cable did the trick.

Nothing shows up

Just completed a Railcore II build yesterday that was started last year. The paneldue worked fine until I erased it to install the latest firmware. The erase button worked but the reset button had no effect. The screen went blank but the paneldue is not recognized by Device Manager (Win7). I've tried different USB cables on 2 different Win7 PCs and the paneldue is not showing up. Is there anything else I can try to recover this?

To reset a heater fault without restarting, simply enter M562. No other parameters are needed and this will clear a heater fault on all heaters

I can't explain the mystery as to why PA is causing this problem, very strange that everything works when it is turned off. PA is such a good feature, its worth trying to get it to work. I am recommending that you consider increasing your extruder motor current. 400mA seems low to me, as I am running 800mA on my Ormerod 2 and 700mA on my Delta.

Your M665 command is using a value of H1026.4, but according to your drawing is really only 111.4 (102.4+9). My guess is that your smart effector autocalibration routine that you are relying upon to set your endstops might be a little less inaccurate if you used a value that was closer to what the actual value is. I'd change it to H116.4 (based upon your drawing and photo + 5mm) and re-check. Once your calibration is set simply transfer those settings it derived (for M665 and M666) to your config.g

Pardon me while I go order another titan extruder cover.

I replaced the clickety-clackety titan on my Kossel this summer with a Bondtech BMG. (After reading @deckingman's excellent review.) Do yourself a favor, you won't regret it.

Something I think being missed is that this "pattern" is fairly consistent.

Consistency makes me think the problem is with your motion-mechanics. If the problem was with the nozzle you would not be experiencing this consistency. I think that something new has either loosed up, or is now binding. Do you see anything wiggle when you attempt to move the effector around with one finger pushing under the hotend? Is your Orion mount still ok? Pulley grubscrews and effector rod connections still tight? Motor mount screws tight? Carriages still free? Also examine the drive belts carefully for damage or stretch marks.

@dc42 This makes sense as I've recently lowered the speed setting down to 30mm/s on the Ormerod. Thanks for your help.

Good idea, I'll try it when I'm back at layer 1. Just started a 6 hour job..

Both of my printers use a geared extruder. You can see the gear stop at the end of a pass when pressure advance is working, or feel it stop when touching it. Or see that it is not stopping when PA is not working. What got me to look at it initially was the buildup of plastic at the end of the run that pressure advance normally prevents.

I have two Duet-Wifi controlled printers, a Delta and an Ormerod 2. I've just recently become aware that pressure advance is not working on layer 1 on the Ormerod 2. Pressure advance on layer 2 and above is working as expected on the Ormerod 2 and works on all layers on the Delta. I'm using the same command on the config.g on both printers, M572 D0 S0.1. I have nothing in the slicer (S3D 4.1) that would explain this problem and do not know where to look to correct this issue. Here is my config running firmware 2.01:

I followed the instructions here:
https://duet3d.dozuki.com/Wiki/Connecting_and_configuring_fans
I am connected to fan1 and my config has "M106 P1 T45 H1"

This is coming from this command in your config:
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C.
Delete it or add a semicolon in front to disable it

The bottom two ridges look exactly like a drive belt. Do you have the option to use a belt that has not been doubled up?

I'd first test each motor individually to make sure they are running in the right direction:

280mA does seem too high for a (3) 4 color LED segment. If adafruit's RGB strip's LEDs have the same values as their RGBW strip and each color LED uses 20mA per segment, then each 4 color - 3 LED segment would use 80mA.

@mikebridge Interesting. I should have looked at their video before responding. I am curious how you will connect this to get all four colors? I assumed that all LEDs would have to be lit to get white, but maybe only the white LED comes on for white?

@mikebridge Adafruit's documentation is here:
https://learn.adafruit.com/rgb-led-strips/current-draw
You could also disable an unused heater output to drive the LEDs if the 1.5 amp fan connector limit is an issue.

@garis I've observed that the unwanted opacity with PETG that you described is not caused by temperature fluctuations, its caused by too much speed. My Ormerod (.5 nozzle) and Delta (.4 nozzle) both begin to exhibit this issue above 35 mm/s and it gets worse as speed increases. When sliced at 30 mm/s there is no opacity.
