Hi David
Test 2.02RC5 on my Scara
Homing ok --> oup's ko

But after homnig absolute movement return error
possible move just on relative movement ...
Move on G90 impossible ...

G90 ; absolute movement
G1 Y0 X0 F1000
Error: G1/G2/G3: intermediate position outside machine limits

UPGRADE ...

David if i remove G1 S2 X1 Y-1; on my homeall.g before G0 I always have the same error as on the versionn 2.02RC4 brief G30 does not work and homig is wrong ...

; Home Z ir-probe
G91; Add test ...
G1 S2 X1 Y-1; Add test ...
G90; absolute movement
G30; Single Z-Probe

In short on scara I have the same concerns as on version 2.02RC4

Hi,
I'm still facing the perfect ,or more possible accurate ,calibration. And in the meanwhile I discovered a bug.
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 ) . If this happen when the filament is near the nozzle occur the muse bite because the gears run faster the capability of the nozzle to release the material . (this because the manual extrusion for load the filament is done fast - my printer have near 15cm between the nozzle and the extruder gear)
I can reproduce this as many time I want.

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

Working fine on homebrew kossel.

@dc42 correct, no pulling of SD. There really wasn't anything I was doing directly, except for being in proximity to it.

Are you certain that X0 Y0 is accessible in a straight line from the initial position? What happens if you use G0 instead of G1?

This is the homeall.g file on my SCARA:

; Home All file for Robotdigg SCARA arm printer
M561			; cancel bed compensation
G91

G1 S2 Z28 F1000		; raise Z to keep nozzle clear of base frame

G1 S1 X200 Y200 F1000	; home proximal and distal arms
G1 S2 X-5 Y-5 F1000	; back off
G1 S1 X10 Y10 F200	; repeat the homing more slowly

G90
G1 X-75 Y75 F3000	; move to a position that correspond to one of the M557 grid points
G30			; home Z
G1 Z28 F1000		; move to safe height again

G29 S1			; load height map

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.

@David

I have exactly the same problems as with version 2.02RC3
https://forum.duet3d.com/topic/7316/firmware-2-02-release-candidate-3-now-available/70

tested with your homing.all file adapted to my config, the same errors ...

Downgrade 1.21RC3 waiting ...

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.
