If I use the microstep 0.05 from the WC by pressing the Z-Baby stepping button, before or after a manual extrusion always from the WC ,the printer replicate the same extrusion as an other manual input (see picture ) .

Thanks for reporting this, it's on my list to investigate.

I confirm this issue. It will be fixed in 2.02RC6.

Installed and working on a Larg-ish delta (600mm x 600mm). No issues found so far. Have done a couple of prints, one of them about six hours.

And... this did clean up the HTTP line ends (reported in a separate thread, now marked resolved).

Some odd behaviour during pause & resume:
I have this in my resume.g:

G1 R1 X0 Y0 Z3 F6000     ; return to point previously paused at (but above it)
G1 R1 X0 Y0 Z0 F180      ; return to point previously paused at (lower nozzle)

G1 R1 X0 Y0 Z3 actually moves to X0 and Y0 - instead of the "last saved point".
Then it move 3mm down.
Then it seems to continue to the correct "last saved point" location (not sure if this is still from with resume.g or already the next commanded move from my print code).
Now it obviously crashes because the nozzle is too low.

This is repeatable. Print something for a few minutes. Pause. (I usually do a filament change or clear a heat-creep and command some manual extrusion to prime the nozzle). The Resume. Then crash (if I'm not quick enough with the E-stop).

I might have tweaked my config - but I don't see anything obvious in my version-controlled config files...
@dc42 Should G0 R1 X0 Y0 behave the same as G1 R1 X0 Y0?

edit: I just flashed RC4 again - and the problem is gone. So this is a regression in RC5.

Strange, nobody else has reported this and I have similar lines in resume.g. I will test it again.

RRF restores the last print position automatically immediately before resuming. Using G1 R1 commands is optional, and allows you to control how it is done. G0 R1 should behave the same as G1 R1 except that on some machines (e.g. SCARA) the movement may not be linear.

@dc42 I have a corexy. With RC4 it works as expected. RC5 moves to the wrong position.

I suspect the G53&G54 changes might have introduced a bug?

Were you using workplace coordinate offsets when this happened?

resam

@dc42 said in Firmware 2.02RC5 now available:

No - I'm running in a simple plain FFF mode as 3D printer.
I do not have any G53 or G54 codes in my sys/ or macros/ files.

Thanks. Are you using any G10 tool offsets?

EDIT: or M206 offsets?

The only G10's I have are hotend temperature and retract commands:
G10 10 P0 S0 R0, G10 S175 and similar.

EDIT: or M206 offsets?

No.

I do have a M208 with a negative Y minima - which I use as a pause position - maybe this is causing a weird edge case ("out of workspace"?)

My pause.g:

M83                      ; relative extruder moves
G1 E-2 F1200             ; retract
G91                      ; relative moves
G1 Z3                    ; raise nozzle
G90                      ; absolute moves
G0 X230 Y-5 F6000        ; move head out of the way of the print and clear nozzle
M106 S0                  ; fan off

My resume.g:

G0 R1 X0 Y0 Z3 F6000     ; return to point previously paused at (but above it)
G1 R1 X0 Y0 Z0 F180      ; return to point previously paused at (lower nozzle)
M83                      ; relative extruder moves
G1 E2 F1200              ; undo the retraction
M106 R1                  ; restore fan speed
T R1                     ; restore tool selection

I based these scripts on https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Pause_resume_and_cancel_files - but it seems some of it is redundant now because RRF already does the same steps before/after calling resume.g

dc42

Even though the G0 R1 and G1 R1 lines are not strictly needed, they should still work, at least if you are not using workplace coordinate offsets or tool offsets. As you are not using either of those, I don't know why they are not working properly. The negative Y coordinate is OK. I tested pause/resume in 2.02RC5 using this resume.g file:

; Resume macro file
G1 R1 X0 Y0 Z2 F5000 ; move to 2mm above resume point
G1 R1 X0 Y0 Z0 ; lower nozzle to resume point
M83 ; relative extruder moves
G1 E4 F2500 ; undo the retraction

resam

I flashed RC5 again - the bug is repeatable.

I added beeps to my resume.g to check when the faulty moves are made:
The G1 R1 ... commands in resume.g are not correctly executed. The head seems to be moved to (0,0) in absolute coordinates (front left corner).

The following similar moves in the firmware seem to be correct.

With RC4 this works as expected.
So this bug seems to happen somewhere during/before the execution of resume.g, because once we enter the resuming_1 state, it behaves correctly.
HandleMCode for case 24 is pretty simple - so I suspect DoFileMacro again...

resam

@dc42 I think I got a reasonable outline of what is happening:

When we call resume.g, DoFileMacro sets useMachineCoordinatesSticky = true.

@resam, thanks for your analysis, that looks like the explanation. The odd thing is that I ran pause/resume tests on my delta, and I didn't see a problem.

I'll fix this and run tests on multiple printers. Also I'll rename UsingG54, it's related to to G53 not G54.

Please can you try again, but this time:

Verify that firmware 2.02RC5 is definitely installed (send M115 to check)
Check that you don't have a deployprobe.g or retractprobe.g file in /sys on the SD card, unless you are using BLTouch
If the problem still occurs, send the commands in your homing file one by one to establish which command is failing.

My SCARA is working fine on 2.02RC5 with just G30 for Z homing, provided that I home prox+distal first. I am using an IR sensor, so I don't have deployprobe.g or retractprobe.g files.

I believe that I've encountered this same issue a few times. My resume.g is identical the one posted by @resam , though mine also contains a M906 to reset the idle current for the stepper motors (I set the idle current to 100% in my filament-change.g)

In my case, the nozzle crashing against the print has, I believe, caused physical damage when the part fan duct was shoved against the side of the print, and pressed hard against the wires from my heater and Pt1000 thermistor. (Apparently, smashing the side of a PT1000 where the wires come out can be bad for the PT1000.)

Note: I'm not trying to make any claim for the destroyed thermistor. I completely recognize that I'm using RC firmware and that's one of the risks I take. On the other hand, I'm hoping that @dc42 can get a fix for this particular issue out more quickly considering that it can cause physical damage.

OBELIKS

I also have a problem with 2.02RC5. As you can see I have 2 tools defined, and for one of them I have Z offset.
When I try homing T1 Duet ignores Z offset (I go to 0 on end). 2.02RC4 works as intended.

I'm sorry it may have caused damage. I've added a warning in the what's new file and also on the release page for 2.02RC5. I've already implemented a fix in the RC6 source.

Phaedrux

I think I was just bitten by the resume bug. I was printing with some stonefil filament that is rather brittle. The filament broke midprint and I paused it so I could reload it, when pausing it dropped the print head to Z5 instead of raising it by 5, and I didn't really notice it as a problem. When I resumed the print it moved the print head diagonally back to the resume point and in the process smashed into the print popping it off the bed. No damage that I can see thankfully.

Here's my pause and resume files just for the sake of completeness.
