Pay for config / json files for my corexy printer build.
-
Evening all,
Just wanted to ask when the printer has finished its task how / where do I ask it to lower the bed and come back to the homing corner minima on x and y to cool print head down bearing in mind my origin is the centre of the build plate.
M104 S0 ;Turn off extruder heater
G91 ;Relative positioning
G1 Z 10 E-5 F300 ; Lower bed by 10mm and retract filament by 5mm
G1 S1 Y-150 X-150 F500 ;Move nozzle 150mm home direction out of the way of finished print.
M84 ;Motors off
G90 ;Absolute positioning -
Does this help? https://forum.duet3d.com/topic/6760/stop-g

@zapta thank you !

Evening all just wondered if one of you kind folk could cast an eye over my config file to see if it could be improved in any way please speeds and placement of codes within the file.
As always your comments greatly received

@stevo If I was being really pedantic I'd say that you have disabled thermostatic mode for your part cooling fan (M106 P0 H-1) which is fine, but the comment after says "Thermostatic control is turned on" (should say "off").
But I'm not feeling pedantic so I won't make that comment.
Seriously, nothing leaps out as being obviously amiss. I think you are at the stage of playing around with things to see if the end result looks any better or can be printed faster without degrading quality. One good thing about Duet is that you can play around with things "one the fly".
If you want, you can give your heaters and fans names for example such as "Hot end" rather than the default "heater 1" (M305 "S") or "Part fan" rather than "fan 0" (M106 "C").
You could try firmware retraction (G10 /G11). It won't work any better than your slicer but you can play around with it "on the fly" which is a far easier way to tune the retraction settings.
You could also play around with pressure advance (M572).

Thank you for the input always appreciated !

I have been tinkering with the driver speed settings in the config file only would this have any effect on the bltouch operation as when the x and y axis has homed and the head moves to the centre the bed raises a little before the bltouch has lowered the pin then changes its mind and lowers the bed.
The bltouch then flashes red -
You can add a bit of a pause delay to the probe movements with M558 R0.5. This gives the BLTouch a half second chance to settle before starting to probe.

Afternoon everyone,
I wonder if I could seek some clarification please Part cooling fan and hot end fan operate as they should during the print apart from the part cooling fan not turning off when the print has finished which I'm guessing I need to add a line to my S3D end code this is what I have in the config g file .; Fans
M106 P0 S0 I0 F500 H-1 ; Part cooling fan
M106 P1 S1 I0 F500 H1 T35 ; Hot end fan set to come on and off at 35and S3D end code.
G91 ; relative positioning
M104 S0 ; extruder heater off
G1 E-1 F300 ; retract the filament
G1 Z15 F1000 S2 ; lift Z relative to current position
G1 S1 Y-445 F1800 ; move quickly to Y axis endstop and stop there (first pass)
G1 Y5 F1000 ; go back a few mm
G1 S1 Y-445 F360 ; move slowly to Y axis endstop once more (second pass)
G1 S1 X-445 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 X5 F1000 ; go back a few mm

@stevo Add "M106 S0" to your end gcode.
-
Thank you
-
Just wanted to thank all those that have and continue to help me on my build thought I would share a pic of last nights print.
Still trying to get my head around the intricacies of S3D some good and some bad lol
-
Looking good.
-
@stevo, looks very good. Maybe now you can help me achieving similar print quality
-
@stevo Glad to see the progress you've made since 26th June. All without paying a bean too.
I hope you understand why we pointed you in the right directions for you to do it yourself, rather than take your money and do it for you. If you haven't done so already, you'll soon be helping others with the knowledge that you have now gained. -
Thanks again everyone for your continued help much appreciated and will hopefully be confident enough to help others.
