Unable to print form Slic3r…

vbtalent

I was running a test print this morning, well attempting to, and ran into a problem where it begins to read the gCode but then stops after a G28 and doesn't execute the next line.. I can manually execute the G1Z5 F5000 line, any ideas on what I'm missing or doing wrong?

Does the home all complete properly? Surprised that you can move the Z axis at 83.33mm/sec.

vbtalent

Looks like that is by default in Slic3r… I've since changed to something more reasonable but still no joy.

The file never appears on the Print Status tab in Duet but it does seem to run through some of the gcode, odd...

It's like there is some error in the code? Nothing being displayed on the screen though.

VB,

deckingman

From what you say, it looks like it's getting stuck after the G28 which is why I asked if home all works. Does it? Is it really getting stuck before it moves the bed 5mm? Or is it stopping at the line after that which is to wait until the hot end reaches 195 degC ?

Ref the Z axis speed, it'll be limited by the maximum value you have in config.g (which I would hope is a lot lower) so it deosn't matter what speed slic3r tells it to move at.

dc42

Which firmware version are you using?

vbtalent

Firmware is 1.19.

Here is the modified code I'm running.. nothing more than a change to the speed from G1 Z5 F5000 to G1 Z5 F500.

It looks like it skips the Z5 move but successfully sets the heater for the hot end, it never turns it on though??

VB,

dc42

Are you printing a file on the SD card that was generated by slic3r, or are you trying to use slic3r to send the gcodes over USB?

vbtalent

I've copied the file to the SD card.

vbtalent

Maybe I configured the hot end incorrectly in the config.g?

;E3D
M143 H1 S285              ; Set the max temp of the hot-end in c-default is 280c
M305 P1 T100000 B4725 C7.060000e-8 R4700	; E3D thermistor
M307 H1 A324.6 C134.8 D3.7  B0				;Set E3D to use PID mode

deckingman

I'd say its doing the Z move but does not continue because there is no tool selected. Try putting a "T" command before anything else in the start gcode i.e if you only have one tool put TO at the beginning, before M104.

vbtalent

Does that not go in the config.sys? This is currently the last line in mine along with the tools section…

...
; Tools
M563 P0 D0 H1 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C
...

; Miscellaneous
T0 				; Select first tool

Seems strange to have to have it in 2 places…

deckingman

If you have T0 in config.sys then no, it shouldn't be necessary to put it in the start gcode. IMO it's it's best working practice though just in case there is something in a homing file that might change it.

That's a good point when I think about it. Can you post your home all file please.

vbtalent

I'll try adding the T0 to the Slic3r gCode and see if things change this morning.

I see there is a place for it to be added in Slic3r in the "Start G-code" section as a permanent item.

I note that you have a comment at the start of your home all file which says "z homing when doing a homeall does not work correctly".

What you happens if you take out the G28 from Slic3R start gcode, (you can use a text editor to do that - no need to re-slice), home the printer manually, then try and print that file?

vbtalent

Yes, just a note when I was knocking out issues that my Z Axis wasn't homing.. fixed it though.

Commenting out the G28 command in the Slic3r code seems to have worked… the G1 Z5 F5000 ; lift nozzle move happened and the hot end heater kicked on. this really doesn't make sense..

However the test print was a total failure, lol! Nothing stuck to the table… and so I've found my next problem.

VB,

dc42

Lots of users have a G28 command in their slicer start script. So I am puzzled. I assume that the text "z homing when doing a homeall does not work correctly" is not actually part of your homeall.g file.

You have G92 X0 and G92 Y300 commands in homeall.g, which is unusual and not needed if you set the axis limits correctly using M208 commands. But I would not expect those to cause the problem you report.

vbtalent

So, if in my config.g file I have an M208. You're saying that it is effectively setting the G92 of the machine?

My current M208 command is the following which I'm now thinking is incorrect?

M208 X0 Y0 Z0 S1 ; Set axis minima

Assuming a 305x305x305 machine should it be the following is order important?

M208 X305 Y305 Z305 S1 ; Set axis maxima
M208 X0 Y0 Z0 S1 ; Set axis minima

I then can remove the G92 commands from all the home'ing config's?

VB,

Dougal1957

that first M208 line wants either the S1 removing or replacing with S0 to set the maxima

http://reprap.org/wiki/Gcodes#M208:_Set_axis_max_travel

SuperJETT

Here's my start gcode from Slic3r:

[[language]]
M104 S[first_layer_temperature_0] ; set 1st nozzle heater to first layer temperature no wait
M140 S[first_layer_bed_temperature]; set bed temp to first layer temp no wait

G28 

T0; set primary extruder
M109 S[first_layer_temperature] ; heat nozzle to first layer temp and wait
G92 E0; set E to 0
G1 X2 Y2 F14000.000; move to front left corner of bed
G1 Z[first_layer_height] F6000.000; move to first layer height
G1 X220  E24 F2000.000; extrude a line of filament across the front edge of the bed using the 1st extuder
G92 E.5; set E to retraction length defined in printer settings
G4 P1000; wait for ooze to slow
G1 E0 F5400; execute reverse extrusion to retract by length defined in printer settings
G1 Z0 F6000.000; lower nozzle height to 0
G1 X225; wipe purged noodle on edge of bed
G92 E0; set E to 0 for 1st extruder

What's funny is I just recently fixed my homeall macro to match what I was manually doing in the start gcode. I just always had it that way and decided to finally make G28 work the same. That's why there are empty lines before/after right now.

vbtalent

@vbtalent:

VB,

OK, thanks… S0 is for maxima and S1 is for minima in which case order is irrelevant.
