Firmware 2.02 Release candidate 3 now available

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?

@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.

@dc42 I just done that and it’s not reading it, it shows the dame value as F, but even then it moves at 1.7mm/s.

M558
Z Probe type 9, input 0, invert no, dive height 3.0mm, probe speed 100mm/min, travel speed 100mm/min, recovery time 0.00 sec, heaters normal, max taps 10, max diff 0.01�

About the strange notice that a motor not seems to be connected properly... As I did some tests yesterday, the message only popped up during the G32 command...? Maybe this could be a hint to find a possible problem / solution?

1.7mm/sec is about 100mm/min, so that explains it. The question is, why does it have the travel speed set to 100 instead of 2000. Do you have any M558 commands in any other files, for example homing files? If you reboot the Duet and run M558 before you home the printer or run any other commands, does it report 100 or 2000 ?

Did you get this message when running 2.02RC3, or only with 2.02RC2 ? You don't appear to have mentioned it before in this thread.

oh, sorry. I got on RC2 as a "red window- alert". On RC3 I now get a "yellow window" that disappears after a few seconds:

Warning: motor phase A may be disconnected reported by driver(s) 0
Warning: motor phase B may be disconnected reported by driver(s) 0

But the print and anything else works fine...?

Thanks.

Is this on a Duet WiFi, Ethernet, or Maestro?
Are you able to identify which command in your bed.g file provokes it?
Is driver 0 driving the X motor as usual, or have you used M584 to re-map another axis or extruder to driver 0?
What current do you have that motor set to?

What current do you have that motor set to?

It is a Duet Wifi (1.03), it is the X motor, current is set to 800 (same motor as on y). I just tried to figure out what exactly is causing the message but it is really strange! It only pops up sometimes. But if, then it almost always pops up if I start a print. Then after the G32 command and somewhere around the G29. If I don't print, I can move all axis, home all axis etc... (I can even execute my S3D- start-script...?)
As slicer I use S3D, here is the start-script:

G21 		; metric values
G90 		; absolute positioning
M82 		; set extruder to absolute mode
G28 		; home axis
G32 		; auto bed compensation
; G28 Z		; home z
M98 PClean_Nozzle.g 	;
G29 		; mesh bed levelling
M98 PClean_Nozzle.g 	;
G92 E0 		; zero the extruded length
G1 X20.0 Y20.0 Z0.2 F7800 	; start point for starting line
G1 X140.0 Y20.0 E10 F800 	; extrude 8mm filament along 110mm movement in x
G1 X150.0 Y20.0 Z0 F7800 	; separation move Z0 to keep up nozzle preasure
G92 E0 		; zero the extruded length again

and here the Clean_Nozzle.g file:

; go to start point
G0 X225 Y68 Z10 F9000		; Z not yet to prevent crash
M564 S0				; allow negative Z-value
G0 Z4.5				; start point reached

G91 				; relative positioning

; start X0 Y0 front left

G0 X15  Y13 F6000 		; 1. move
G0 X-15 Y14 F6000 		; 2. move
G0 X15  Y13 F6000 		; 3. move
G0 X-15 Y0 F7000 		; end back left

M564 S1				; denie negative Z
G1 Z5				; lift Z at the end
G90				; absolute positioning

dc42

Perhaps it's the nozzle cleaning script? Can you try running it a few times?

You can ignore the message, because the firmware doesn't do anything apart form warn you when the drivers report open circuit motors - but obviously it's annoying.
