Why doesn't this M574 configuration work

[luckyflyer]

Ok, I'll do that but if not configured correctly would that cause the issue I'm having? I thought the axes limits were to prevent over extending an axes and hitting a hard stop.

@luckyflyer i think you're correct, but i'm happy to defer to higher powers on most thing config.

however having Z-0.6 in you M208 and G92 Z0 in your homeall seems odd to me.

[luckyflyer]

Hmm, I did not catch that. I have the -.6 because my bed has a dip in the middle. Front left corner is much closer to 0 but I'll change home all anyway.

[luckyflyer]

Double check your axis limits max and min settings to see if they match the way the new endstop configuration is set up.

Ok I get what your saying.

@luckyflyer said in Why doesn't this M574 configuration work:

Double check your axis limits max and min settings to see if they match the way the new endstop configuration is set up.

Is this the way axis limits should be set up with the new M574 config?

; Axis Limits
M208 X0 Y310 Z-0.6 S1 ; set axis minima
M208 X310 Y0 Z320 S0 ; set axis maxima

As @bearer said several posts ago, you need to swap the Y values over in those two commands. As they stand, no motion will be allowed.

[luckyflyer]

Nuramori, can you post your config.g file, thanks

[luckyflyer]

I can run this code from the console and it prints as it should, at the correct location etc.

G92 E0
G1 X130.0 Y5 Z0.0 F2000
G1 X40.0 E20.0 F1000.0

This is part of my starting script in S3d. I believe that this tells me that my M208 and M574 commands which are configured thus,

; Axis Limits
M208 X0 Y0 Z-0.6 S1 ; set axis minima
M208 X300 Y300 Z300 ; set axis maxima

; Endstops
M574 X1 S1 P"!io1.in" ; configure for low end, active-low endstop on X via pin io1.in
M574 Y2 S1 P"!io2.in" ; configure for high end, active-low endstop on Y via pin io2.in
M574 Z1 S1 P"!io3.in" ; configure for low end, active-low endstop on Z via pin io3.in

are configured correctly in config.g.
However when a S3d print is loaded via dwc with this start code the tool position display in dwc advances to Y5 and then very briefly at X130 then to X40 and stays there and does not change, no filament is extruded.

I now believe that there is something not configured correctly in Simplify 3d for this printer configuration because S3d works correctly when M574 is set to Y1 instead of Y2. Do the experts agree with this or am I missing something?

[luckyflyer]

I'll also add the with the above configuration when homed X=0 Y=300 Z=0 is displayed and that all movements from the console are correct.

I sure would like to get this problem resolved.

[mwolter]

@luckyflyer Please post the contents of the Starting Script tab in Simplify3D.

This is my config.g file, run on a coreXY that's set up as you have (x endstop on the left as min, y endstop at that back as max) for you to compare. It homes to the back left corner, and 0,0 is the front left corner.

I have a toolboard and triple independent z axis on a duet3, so there are parts you can ignore. I always put a pin name legend in the beginning, which helps me keep my wiring organized as a reference when coding this file....

Thanks Nuramori, what slicer do you use?

[Nuramori]

@luckyflyer I use Cura 4.6.1 That actually reminds me, just for giggles, do you have any start code in your slicer, and if so, perhaps posting it may help too. You never know.

[luckyflyer]

look above I just posted it.

[Nuramori]

Do you happen to also have an override.g file in your sys folder on the duet?

[luckyflyer]

I can execute this part of my start code from the console, it works perfectly, but not from within s3d.

G92 E0
G1 X130.0 Y5 Z0.0 F2000
G1 X40.0 E20.0 F1000.0

[luckyflyer]

No override .g

[mwolter]

@luckyflyer I think the issues you're experiencing could caused by the lack of a T0. Here's a few thoughts.

Recommend adding these to the top to make sure typical defaults are set.

G90			; absolute positioning
M83			; set extruder to relative mode - enable relative extruder distances in the slicer
T0			; select tool
M107			; part fan off
M220 S100		; reset speed multiplier
M221 S100		; reset extrusion multiplier

On the G-Code tab enable "Relative extrusion distances"

Not sure I'd recommend this unless your mesh stays incredibly consistent.

G29 S1                                 ; load bed mesh

This is not necessary.

G92 E0                                  ;set extruder to 0

This prime line is extruding at Z0, and it's pushing out quite a bit of filament in only 90mm.

G1 X130.0 Y5 Z0.0 F2000        ; move tool
G1 X40.0 E20.0 F1000.0         ; extrude 40 mm of filament to prime nozzle

If you're using a 0.4 nozzle try this instead.

G1 X130.0 Y5 Z0.3 F2000    ; move tool
G1 X40.0 E10 F1000         ; prime nozzle

This isn't necessary.

G92 E0                                 ; set extruder to 0

[luckyflyer]

Thanks mwolter, So my revised start code should look like this,

G90 ; absolute positioning
M83 ; set extruder to relative mode - enable relative extruder distances in the slicer
T0 ; select tool
M107 ; part fan off
M220 S100 ; reset speed multiplier
M221 S100 ; reset extrusion multiplier
M109 S195 ; wait for hotend temp
M190 S60 ; wait for bed temp
G28 ; home all axes
G1 X130.0 Y5 Z0.3 F2000 ; move tool
G1 X40.0 E10 F1000 ; prime nozzle

[luckyflyer]

Also I must say that S3d was and still would work correctly when the Y endstop is configured to Y1 and all associated homing data is reset to the way it was before the Max Y endstop change.
And my mesh isn't very pretty
