  1. Hi Guys, I am still moving to duet's board.

    Today's problem is the hot end 5V fan, simply I have a problem to turn it on.

     

    I already splitted and plugged black/orange[-] cable on GND of FAN_2 and the red/blue[+] one to the 5V pin of the expansion board connector but it doesn't turn on when the nozzle reaches the target temp.

     

    I don't think but I paste here the part of confing.g maybe is there my problem:

    ; Fans
    M106 P0 S0 I0 F500 H-1                      ; Set fan 0 value, model fans
    M106 P1 S1 I0 F500 H-1                      ; Set fan 1 value, leds
    M106 P2 S0 I0 F500 H1 T40                   ; Set fan 2 value, hotend fan

     

    Edit, the two PT100 are correctly inserted and I read the correct temp

  2. Hello users!

    Finally I am moving to Duet board, the migration is still in progress but for the moment it is really interesting!

     

    At the moment I have some problem with the configuration of the Z axis.

    I have some difficulty especially with the writing of the homez.g .

    I hope someone can help me to write and configure it.

    Edit: I did the Configuration tool but the homez.g seems incorrect for the um.

    I found this in 4.0 app

     

    Bel lavoro Pieri70! These extruder[K]_filament_used are interesting, but in my opinion the most interesting are those with the = => =< and other simbols after the placeholders.

    @neotko posted some screenshots some time ago, I tried to use some of those but without results, without a serious documentation it is quite hard to improve the profiles and the prints.

  4. I'm interested too, I would like to replace my UM2's fried board with the duet.
    What about coding via reprap code and cabling? I've read the documentation pages and it seems intuitive, but I'm a bit scared to get my hands on the electronics as my electrical background is pretty basic

  5. With a lot of walls is hard to get a 100% top fill, you can try to reduce the line width and lower the numbers of the outer wall to increase the top infill area, with the right amount of overlap it should works nice

    {IF NEWTOOL=0} M104 S[extruder2_temperature] T1
    {IF NEWTOOL=0} M104 S[extruder0_temperature] T0
    {IF NEWTOOL=1} M104 S[extruder2_temperature] T0
    {IF NEWTOOL=1} M104 S[extruder1_temperature] T1

     

     

    You have to insert the idle temp after the T[new_tool] line otherwise the firmware ignore it and drops the temp at something like 175/120/80.

    Example, T0 is the idle/old tool, T1 the new active tool :

     

    T[new_tool] / T1 ;

    {IF NEWTOOL=1} M104 S[extruder2_temperature] T0 ; T0 at idle temp

    {IF NEWTOOL=1} M109 S[extruder1_temperature] T1 ; wait T1 active temp

     

    I really like your idea to use another extruder to set the idle temp!

     

    About the placeholders, the main ones are posted from neotko in the link above here, other instead are scattered in S3D forum.

    You must Change it that if you Print the "colder" Filament, that you set it to the Temperatur from the Hot Filament with M109

    and after that to the Temperatur of the cold Temperatur M104 and start in the same Moment.  So it will print first time to hot,

    but will connect with the hottest Filament and after a short Time it will have the right Temperatur...

    I don´t know, if you understand, what I mean. But it will not work. I must test it with your Skript and another line (M104 at last..).

     

    I have not understand completely, your problem is the material temp or the script temp? 

    Note, I use this profile on a UM2 with the mark2, I never test it on a um3

  8. I prefer seperate movements because if there are some ooze under the nozzles the "script" lock and stick the ooze on the prime pillar or the shield and it will not fly over the printed parts, go up on the nozzles or scratch the object with the wrong material.

     

    The final script moves the head and the build plate in to the switch direction and it can be completely stripped, until now it never give me problems.

     

    I know that there are a lot of zero extruder but with the current version they are necessary to avoid wrong positioning of the materials lenght.

    You are right @tinkergnome, I will add a warning/readme text file on dropbox whit the note of the profile.

     

    PS, just to be curious, what are inside the T0/T1 and wipe files?

  9. Hello Mark2 users,

    I would like to share my latest version of the mark2 profile for S3D.

    This profile is not issues free, the toolchange process is better and shorter than the previous version.

     

    In addition, I would like to report a minor issue too, with the latest firmware [17.09] during the toolchange the machine ignore completly part of my script:

    G1 X[next_position_x] Y[next_position_y] F[travel_speed] ; move XY first
    G1 Z[next_position_z] F1500 ; zero lift

    The head moves to the next coordinates simultaneously, this isn't a big problem but I would like to understand why it does.

     

    EDIT: forgot the link and some notes

  10. Hello Zeno, your script is right but you do not insert the " ; " after the {IT OLDTOOL/NEWTOOL} placeholders in the toolchange script tab.

     

    Take a look at mine that I use for the mark2: 

    ; PLA/PLA SCRIPT

    T[old_tool] ; old tool

    M104 S175 ; idle tool

    {IF OLDTOOL=0}M104 S190 T1 ; preheat before swap

    {IF OLDTOOL=1}M104 S190 T0 ; preheat before swap

    G92 E0 ; zero extruder

    G1 E-[toolchange_retract_distance] F[toolchange_retract_speed] ; retract old tool

    T[new_tool] ; new tool

    {IF NEWTOOL=0}M104 S175 T1 ; cool idle tool

    {IF NEWTOOL=1}M104 S175 T0 ; cool idle tool

    {IF NEWTOOL=0}M109 S190 ; wait after idle

    {IF NEWTOOL=1}M109 S190 ; wait after idle

    G1 X[next_position_x] Y[next_position_y] F[travel_speed] ; move XY first

    G1 Z[next_position_z] F1500 ; zero lift

    {IF NEWTOOL=0} M104 S[extruder0_temperature] ; final heatup

    {IF NEWTOOL=1} M104 S[extruder1_temperature] ; final heatup

    G92 E0 ; zero new extruder

    G1 E[toolchange_retract_distance] F1200 ; load material

    G92 E0 ; zero extruder

     

    Here is the complete FFF

     

    Edit: look the last version that is better and more precise

  11. Hello, I'm disassemble the XY movement. Before install the new shafts I wanted to check how much the old ones were bent. So I made them rotate (in place) on the buildplate glass and checking the contact area and...SURPRISE! They are not bent! I tried it on two different plates, in different position, with and without bearings as you done in one your video.

    At the moment I'm really confused.

    I noticed instead that, a flanged bearing has some play in its hole on the back plate, exactly one that hold the shaft that seemed bent.

    Is it possible that this was the cause? I don't know.

    Now I will insert some ptfe seal tape around the bearing and after I will reassembled all, I will see if something will be improved.
