flashforge dreamer3d #5

Closed valueerrorx closed 4 years ago

valueerrorx commented 4 years ago

do you have any idea how to adopt this cura profile for the dreamer3d ? i managed to get it to work with one extruder but it did a really bad printjob and used to much filament..

it works gread with slic3r https://github.com/valueerrorx/slic3r-dreamer3d so the gcode shouldn't be the problem. the same gcode used in cura doesn't work at all...

i think it's a problem with the flavor

valueerrorx commented 4 years ago

https://github.com/valueerrorx/Flashforge-for-Cura here is the (half baked) version for dreamer3d (a fork of your repository) with all of the neccesary files for dreamer3d as a starting point for everyone who want's to give it a try

Toylerrr commented 4 years ago

I dont have a dreamer but after looking some stuff up i have some info that might help.

The Dreamer uses gcode not x3g so it should be easy to get it working.

This is the gcode straight from flashprint for the starting Gcode

M118 X17.70 Y17.70 Z34.89 T0
M107
G90
G28
M132 X Y Z A B
G1 Z50.000 F420
G161 X Y F3300
M7 T0
M6 T0
M651
M907 X100 Y100 Z40 A100 B20

This is what it had from the End Gcode

M104 S0 T0
M140 S0 T0
G162 Z
G28 X Y
M132 X Y A B
M652
G91
M18

Also in your cura setup you have the dreamer set up with machine_x3g_variant": "r1d", (You shouldnt need this)

"file_formats": "application/x3g", (this should be something like "file_formats": "text/x-gcode") and

"machine_gcode_flavor": { "default_value": "RepRap" }, (should be something like "machine_gcode_flavor": { "default_value": "Makerbot" } )

wow thx.... i'm going to give it a spin tomorrow

valueerrorx commented 4 years ago

holy shit .. this went south.. first of all the flashforge dreamer3d claims that there is an error in the file when using "Makerbot" flavor.. i already figured out that it would accept the file when using "UltiGCode" -- so i did that..

then the dreamer started to move down the plate (but didn't stop) and immediately started printing (moving the extruder printing into thin air) but it didn't pre-heat.. lucky me ;-)

so i changed the gstartcode and endcode to what i know is working in "slic3r" and voila.. it heats up and perfectly starts printing.. well.. almost.. haha.. it heats up both extruders even though only one is needed and it spills the filament and moves in it's own mess..

dreamerwithcura

do you have an idea how to fix this?
it heats up to 220°C which i thought is to high but then slic3r does the same thing..

from looking at the produced gcode files (ultiGcode vs makerbot) i can say that the ultigcode (the one that works) moves the filament almost twice as much.. (the E numbers)

this has to be the reason why it extrudes to much of it... hmm.. now what... Screenshot_20200121_144248

valueerrorx commented 4 years ago

okay.. i found a manual fix and therefore the reason why "flashforge dreamer3d" cancels the print immediately with the makerbot flavor (which is the correct one)

Screenshot_20200122_125256

those 5 lines are the cause..

T0 M190 S50 M104 S200 M104 S200 M116

if i delete them in a text editor the dreamer3d starts printing and does a very good job at it..

this selects extruder 0, preheats bed an nozzle afaik.. but it's also part of the gstartcode i provided so it makes no sense that those lines are added..

with a LOT of trial an error i figured out that only one of them causes the print to cancel imediately T0

i have to remove T0 and the file works fine..

Toylerrr commented 4 years ago

Those lines are added by Cura itself, Sounds like for it to not have those you would have to work the gcode start script to have the correct temp variables.

M190 S{material_bed_temperature} M104 S{material_print_temperature}

This would only be for duel prints because it heats up both sides of the extruder would heat up.

Hello! I don't have a Dreamer but a DreamerNX and I made a definition for Cura. I looked at your definition. When changing printheads, maybe adding this line to the extruder file helps? "machine_extruder_start_code": { "default_value": "\ nM108 T0; Select Active Extruder \ n" } And the beginning of the G-code maybe should \nM104 S{material_print_temperature_layer_0} T{extruder_nr} ;Set nozzle temperature to first layer temperature\n

I also couldn't get rid of the T0 command before the start code.
