Start Script and how to stop Gcode input

[B-H-S]

Hi

I asked this question in another thread but no answers so I'm stuck,, hears hoping someone can help??

I doing a start script for a Taz 6 (which is fine) but when I create my code S3D put 7 lines in

G90
M82
M106 S0
M140 S60
M190 S60
M104 S205 T0
M109 S205 T0

which I'm hoping I can stop,, Most of this is already in the start script, and the temps are to high, as the cleaning sequence is at 140 so the process would go up, and then down, and then upagain in Temp..

Have you checked all the scripting tabs in S3D?

S3D could be adding those lines because you have entered those lines in the GCODE start tab, in the extruder tab or somewhere else.

Yes I have checked all the tabs but those settings are not in any of them ??

stumped at moment

Have you checked you are using the right firmware flavor?
If yes try to look in the settings (don't remember where it is) for the gcode building settings which should be the real slice to gcode translator.

Otherwise I wouldn't really know what it could be. The only other thing you could do is taking a different printer profile and customize it to your TAZ 6 and check if it behaves the same.

Ok, this is an issue i had a long time ago. if you manualy set your temps in the start script you need to make sure that you have one set prefeably the last set of bed and extruder tempertures set to the S3D variables for the same.

I belive this post was the one that i orginaly found out about the odd behavure of temp: viewtopic.php?f=8&t=1959

I was setting a lower set of temps to do all my autocalibrations for my delta printer and saw the same rise drop and rise in the temps. I also saw it in the gcode file that it was duplicating the operating tempertures. So that was what had me dig into the code of scripting.

Code: Select all

G28 ; Home axis
M106 S0 ; Fans speed off
M140 S50 H0 ; Sets bed temp [bed1_temperature]
G10 P0 S150 R150 ; Set T0 active and standby temps
T0 ; Activate tool 0
M116 P0 H0; Waits for active temp of T0 and Bed0
G4 S30 ; Wait for 30 seconds
G32 ; Bed probing
G29 S1 ; Load bed mesh
M140 S[bed1_temperature] H0 ; Sets bed temp 
G10 P0 S[extruder0_temperature] R175 ; Set T0 active and standby temps
M116 P0; Wait for T0 tempture
G4 S30 ; Wait 30 seconds

The above is my start code for my delta for referance to how I have it set and i actualy have it fully commeted so i can go back later and understand what i did when i created it

What's your starting layer temp at? Do you have any startup script code?

If your first layer temp is 205, it might be setting it at that first. One way around this would be to set your first layer temp to the lower temp, do the bed leveling, then have the 205 or whatever temp set at the end of your starting script.

What's your starting script? I have a Taz 6 as well and didn't have this problem that I recall (moved back to the dual extruder now).

It purposefully goes to a higher temp, has some ooze, then cools down, but I thought all of the bed leveling for the taz was in the startup script and s3d just copied it from the cura settings.

Thankyou for replying I have been sat waiting for some advise so not ried anything

my start script is below

as said this is for std single head

when I produce the code I get (will only show first 8line of real code not bother with the beginning run down

as you can see first 7 klines are not mine after digging I came to conclusion you cannot get rid of these ????? but I hope Im wrong...

let me know your thought and thanks ??

I just uprgraded to 4.10 and used there sartup script and this was at the beginning of the code

G90
M82
M106 S0

then the rest is as per sart script so it can be done ??? thoughts , there print speed is set at 3360 which is way faster than I print?? personal choice ….
