Firmware 2.02 Release candidate 3 now available

BlueDust

Z Baby Stepping doesn't seem to work any more.
I just updated DWC to 1.22.4 to see if that would fix it, and it did not.

Current version
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet Ethernet 1.02 or later
Firmware Version: 2.02RC3(RTOS) (2018-10-17b2)
Web Interface Version: 1.22.4

Is anyone else having this problem?

It seems to be working for me from both the 1.22.4 DWC (that was just put out today) and from the PanelDue 1.22 released a couple days ago. (It's annoying from the Paneldue due to the "response" popups, but it seems to work.)

What symptoms are you seeing that suggest it's not working?

M557 now supports a P parameter to set the number of X and Y points, as an alternative to using the S parameter to set the spacing

So I can write M557 X30:260 Y15:245 P9
Instead M557 X30:260 Y15:245 S57.5
and the firrmware automatically calculate probe point spacing right?

Yes, that's correct.

@dc42 updated to 2.02rc3 and dwc 1.22.4-b1. Since upgrading whenever I scroll down in DWC it automatically scrolls back up a couple seconds later. Very irritating. I'm using Safari 12.0. This hasn't been a problem with any previous version. It seems to print fine however.

Could it be related to this bug? https://www.thingiverse.com/thing:2448907

On previous versions of Chromium, I was able to set the 'enable-scroll-anchoring' to true, and it fixed the problem. But in recent versions, this flag does not exists anymore, and the bug came back (on Thingiverse, I didn't try Duet latest firmware).

I press the neagtive or positive buttons and the nozzle doesn't get any closer or further from the bed. I use this all thr time adjust the squish during the first layer.
I didn't reboot my printer a second time after installing the 3rd beta of the firmware. I will do that when I get home and see if that fixes it.

How big are your baby steps configured for? Does DWC claim that the baby steps are taking place? (It shows the current babystep.) On mine, I never actually measured the nozzle distance to ensure that the babysteps were happening, but I know that I'm about 0.04mm too high on my manual level, and if I don't babystep, everything curls up.

I hadn't thought much about this, but I'm seeing something similar.

Baby steps are configured as 0.05mm, but I'm not seeing any effect on the machine. It changes the compensation factor on the DWC, (I had it showing up to a full 3mm of compensation at one point) but it didn't move the Z axis motors at all, so far as I could see.

My last few prints, I just stopped using it, because I thought that it might be something in my Z speed/acceleration settings not letting it get started for such a small move.

This started when I upgraded to 2.02RC2, still happening with RC3, however I also changed my Z lead screws when I upgraded to 2.02RC2 from 5mm/0.8mm lead to 8mm/8mm lead (4000 steps/mm to 400 steps/mm.) I had assumed that it had to do with the change in lead screws. I don't have those values from my config.g in front of me at the moment.

BlueDust

@garyd9
Default change is .05mm and it does say its changed. Usually I change this value from .25 to .35. After a 5 point calibration, start a print, change this Z level to around .25 / .35 to get a good squish going.
Usually stays pretty close to that initial adjustment after many 5 point calibrations until I power off/on again. And then I have to make this adjustment again.

Right now when I push the button - or + no changes are made, and as such, my prints don't always stick. This was working a 2 days ago. Appears like it stopped a day or two after I installed beta 3. I don't reboot the machine often so I may have rebooted it for the first time after installing the beta, but emergency stopping a print or something, that started this issue... Just saying that possible. Will reboot again when I get home. If that doesn't fix it will reinstall the current beta and if that doesn't help may reinstall beta 2 to confirm, as it was working for me.

Thanks

WARNING: What follows is a WAG. Well, and educated WAG, but still a guess.

I wonder what the actual gcode DWC is sending - in particular if its actually sending a M290 R0 or M290 R1.

I wonder this because there's a commit that appears to be functionally different for R0. Previously, it would call PushBabyStepping(val - current). Now it's calling PushBabyStep(val)

I really don't understand the code I'm looking at, and my initial impression is that this change fixes a bug where the absolute mode (R0) was doing relative changes instead of absolute changes.

dc42

The only change made to baby stepping in RRF 2.03RC3 is to remove the limit of +/-1mm change when using absolute mode.

Old code:

const bool absolute = (gb.Seen('R') && gb.GetIValue() == 0);
float difference = (absolute) ? fval - currentBabyStepZOffset : fval;	
difference = constrain<float>(difference, -1.0, 1.0);
currentBabyStepZOffset += difference;

New code:

const bool absolute = (gb.Seen('R') && gb.GetIValue() == 0);
float difference;
if (absolute)
{
	difference = fval - currentBabyStepZOffset;
	currentBabyStepZOffset = fval;
}
else
{
	difference = constrain<float>(fval, -1.0, 1.0);
	currentBabyStepZOffset += difference;
}

Like I said (typed...)

For some reason when I was staring at the diff, it wasn't clicking in my head and I wanted to be clear about that when I posted. I had intended to followup when I got home, but I'm married with children. (I think that explains everything.)

I did see some weirdness with babystepping last night myself, but that was a case of the paneldue reporting an offset of 0.00 while DWC was reporting -0.02. I think DWC was correct, but it's very difficult to measure 0.02mm while the nozzle is moving.

You can see what DWC is sending the Duet by opening the Developer Tools for your browser (usually F12), select the Network tab and then click any of the buttons and you'll see something along the lines of http://ip_address/rr_gcode?gcode=

@garyd9
I would expect it to be impossible (or close to) to measure those small changes. I just print and change it during that first layer and see the difference. But even changing it 1mm + or - doesn't do anything anymore. And that should make big obvious changes to the print.
I am back to recalibrating Z with every power on (before I discovered the baby stepping button). Not a big deal, just takes more time.

Thanks for looking into this.

Hi, I have a problem when running G29 to probe the bed. For some reason the moving speed between probe point it's extremely slow. I have M558 P9 H3 F100 T2000, but no matter what T value I put, it always moves at 1.7mm/s.

It was working fine last time I used it, and I sincerely don't remember to have modified anything else (but perhaps I did...)

Any clue?

Phaedrux

@3doeste do you have the max speed limited in your config?

Run M558 without parameters, to check that the T2000 value in config.g has been read properly.

garyd9

Are there any restrictions on the commands usable in M600 macro? (filament-change.g ) I tried it tonight and when it hit the M600 macro, everything froze. The macro contained the following commands:

M83
G1 E-4 F2500
G91
G1 Z20 F5000
G90
G1 X0 Y85 F5000
M291 P"Change Filament"
M300 P5000

None of the moves in the filament-change.g were run as far as I could tell. It appeared to just freeze when it hit the M600. The paneldue and DWC showed a paused state, but the movement buttons and resume buttons (on both UI's) didn't do anything. The only thing I was able to do was "emergency stop" (which did work.)

Fyi
I just installed a previous version of the firmware and the baby steps are working.
