The recommended print speed is less than 60 mm/s, the recommended travel speed is less than 80 mm/s, and the recommended initial layer speed is less than 24 mm/s.

 

For recommended settings in Simplify3D, please check the attached .fff files.

    I'm a little confused because the settings in step 5 do not match the screenshots in step 3 or step 4. Can you explain? Are the G-code settings in step 5 for the "Printer" tab or the "Extruder 1" tab? Or for some other setting? Thanks!

    Also, in the printer settings your y min and y max are the same value...

    Cura (V4.6.0) does not accept the values you showed in your screenshot.. the X/Y min/max settings can't be greater than zero, it does not even permit you to type any number that is not negative. However, the default values are exactly the negative representation of what you show in the screenshot. Is that what you meant?

    Also, Cura does not seem to find my A350 in Monitor mode, while it was able to connect to Snapmaker Original just fine.. any idea, what could be the problem?

    Maybe it is the version we are using but Cura 4.6 cannot be set with the settings you gave us.. It is not possible to set the values indicated to any positive value. Also the comments in the Gcode for the printer (not the extruder) are partially hidden so I have no idea what they say.

    Can you please clarify as I would not like to damage my printer due to some incorrect setting?

    Also I am unable to connect over wi-fi to the printer from Cura but I suppose I can always use the USB pendrive for this so its not a major problem.

    Thanks.

    For "Starting gcode" I added a few lines so it closely matches the starting sequence of using Snapmakerjs.

    Without M104, M140, M109, and M190 in the "Start G-code", Cura will add an additional code block before the Start G-code sequence to heat up bed, wait for it to finish, then heat up extruder, instead of heat both at same time.

    In some prints, it might be ideal heat bed and nozzle one after another so you don't have a heated nozzle idle for too long and cause other issues, if that's the case I would modify the code accordingly.

    In below, Cura will replace values in curly brackets with what's in your setting

    M104 S{material_print_temperature} ;Start heating extruder
    M140 S{material_bed_temperature} ;Start heating bed
    G28 ;home
    G90 ;absolute positioning
    G1 X-10 Y-10 F3000
    G1 Z0 F1800
    M109 S{material_print_temperature} ;Wait for extruder to reach temp before proceeding
    M190 S{material_print_temperature} ;Wait for bed to reach temp before proceeding

    Good idea to use variables in the Start g-code. By using material_bed_temperature_layer_0 for M140 and M190 the bed will heat to the initial temperature in the same way as Lubin does. By the way the variable for M190 in your example is incorrect.

    If one is going to use G commands that make the machine wait until the required temperature is reached, would it not make more sense to put the bed command before the extruder command, since the bed takes much longer to heat up than the extruder?

    So, instead of:

    M109 S{material_print_temperature} ;Wait for extruder to reach temp before proceeding

    M190 S{material_print_temperature} ;Wait for bed to reach temp before proceeding

    why not have:

    M190 S{material_print_temperature} ;Wait for bed to reach temp before proceeding

    M109 S{material_print_temperature} ;Wait for extruder to reach temp before proceeding

    Is there any clarity about the minimum x and y setting from the printhead?

    Could somebody make a new list of the codes at the start and beginning which is complete and working?

    Hello,

    Is it possible to have a final recommendation for the settings please?

    1) Settings of the printhead

    2) Optimized G code for Start and End

     

    Thanks

    Did anyone find a solution to John Fiott's question about the Cura Profile settings and version 4.6 and greater of Cura not allowing for positive numbers for the x and y min settings.?

    I am going to set the printer nozzle x 40 mm and y 20 mm to compensate... wish me luck ...

  • Boyu Wang

    On the second thought, the size of the printer head probably doesn't matter ...

    I'm getting better print quality with almost the same setup using simplify3D, plus the print are between 30 to 60% shorter! It will be great that you provide a printer to simplify3D that they can test and complete the V2 profiles.

    For Simplify3D, I imported the FFF files above - but they are for the A150.

    For my A350 I changed these values, but I want to be sure this is correct. Screenshot:

     
    I notice the g-code start and end look way less than what is in the Cura section: see screenshot from the imported FFF file.
     
     
    Should we be including all the start and end g-code listed in step 5 above?

    Hey I was trying to do this very thing, and I have been having nothing but problems from the computer anyhow.

    So as far as I can tell, you MUST use luban to print from, buy you can use Cura to make the gcode. I also seem to have to "send over wifi" and not hit the start button from Luban, or it throws an error and i have to reboot the machine and luban to try again.

    I had seen a similar layout of data someplace else with some different values before, I don't know what is right or wrong but so far I have noticed one thing for sure.

    The modified starter code posted by Jiaren Li above is what I am currently using, however there is an error in that. The print bed is trying to go to 120 degrees C, because the variable used on one line seems to be incorrect.

    Snapmaker 2 cannot go beyond 70c (theoretically) so that is not going to work. I adjusted the value manually on my machine but it wouldn't take so I addressed it and i also switched the bed and print temps around so the bed heats first per someone else's comment.

    Lets try this variant:

    M140 S{material_bed_temperature} ;Start heating bed

    M104 S{material_print_temperature} ;Start heating extruder

    G28 ;home

    G90 ;absolute positioning

    G1 X-10 Y-10 F3000

    G1 Z0 F1800

    M190 S{material_bed_temperature} ;Wait for bed to reach temp before proceeding

    M109 S{material_print_temperature} ;Wait for extruder to reach temp before proceeding

    G92 E0

    G1 E20 F200
