Hi,
I am trying to print this model.
My problem is that it prints the down axis with PVA instead of PVA.
My 3D printer has a single extruder, so for that i have enabled a prime tower, so the PVA material gets cold and to have time to change from PVA to PLA.
Any suggestions on what should I do?
Thanks a lot -
Also i would like to ask you something else.. when i try to print this... it prints the bottom axis and the bottom part of the hub with pva... how can I control it and print it with PLA?
Thanks a lot

ok i will try it..thanks a lot

ok i am sending you my 3mf file.

Hello,
I want to make a stucture with my d12/230.
I am going to use 2 materials:PLA,PVA.
PVA is my support. During my printing when its changes ... for example from PVA to PLA ...my extruder moves to the corner.. it is changing the material and then it continues printing.
But as I have one single extruder i have noticed that a little amount of PVA printing with my PLA so my structrure collapses when i put it into water.
Is a solution to keep my extruder more time at the corner so it can put away ALL of the previous material??
If yes... does anyone knows how to change the gcode?
Thanks a lot

Good moring. I tried to put the definition file you posted and my temps loading perfectly. But when it comes the time to print, my extruders does not move from the up right corner and the printer is printing on the air. I post the gcode file.
-
Ohh I am sorry. I will post you know the gcode from cura. I posted gcode from replicatorG by mistake.
-
Yes it is prossible to preheat the Wanhao.

Temperatures does not load again....
I don't know what should I do, maybe my printer has a problem..
I think my settings are right.. Should I do something else, that i do not understand?
-
My printer is like as the photo I had uploaded earlier, so there is an offset and i will to find how much i should write.
Thank you. -
I downloaded cura again and it works. Now i have to see if the temperatures are loading.
Can i ask you sth?
In the settings of extruders, should I put a value on?
Nozzle offset x:
Nozzlet offset y:

Hello guys again.
I am trying to put into the recourses file, a new printer definition and to add the second extruder that i found on github:
https://github.com/fettesps/WanhaoDuplicator4S-Cura
on my duplicator 4s.
I deleted the 4.13.1 version because it didn't load me the temperatures and i tried on 3.6,4.2,4.2.1 as the guy on github tried.
But although i copy the definition,extruder definitions, into the recources files, cura does not recognize the second extruder.
Has anyone any idea on how i can fix it?
Thanks a lot -
ok thanks a lot. I am gonna try sth.
The truth is that because the printer is old, it has a lot of problems. -

So there is an offset between the nozzles. That needs to be entered into Cura Machine Settings. Typically the T0/Extruder1 nozzle will have X=0 and Y=0 (no offset) and the T1 Extruder2 nozzle will have the offset (Example: X=24 Y=0).
I'm not noticing any layer cooling fans. A typical situation with a cooling fan for each hot end would have them numbered as "0" for T0 (extruder 1) and "1" for T1 (extruder 2). If a single fan is covering both nozzles then both extruders would be numbered "0" which is what you have in Cura.
The temperature commands do appear in the gcode. Getting the printer to respond to the commands should be your priority.
You have "Dual Extruder" firmware installed?
No i dont't have Dual Extruder firmware installed.

I don't see any problem in the gcode. At the end of the StartUp sequence - T0 (PVA) is at 215 and T1 (PLA) is at the standby temperature of 175.
Later when T1 becomes active they switch...
T1
G92 E0
M104 T0 S175 ;PVA extruder to standby temperature
M105
M109 S190 ;PLA extruder to Printing Temperature
M104 S180 ;PLA extruder to Initial Print TemperatureSwitching back to T0 for the support...

G0 X114.681 Y96.873
M104 S215That all looks like the way you have it set up in Cura. If they aren't heating correctly then it looks to be a printer problem either hardware or firmware.
In your StartUp gcode this line is no good:
G1 F{speed_travel}
The "speed_travel" replacement pattern is in "mm/second" and the printer wants "mm/minute" so your G1 travel speed is being set to 120 instead of 7200. In addition the G1 command is for extrusions and so you are attempting to set the extrusion speed to your travel speed. Take that line out. Cura sorts it out later in the gcode.
You stated that your printer has two separate print heads but the Machine Settings don't show any nozzle offset. Is that the way the printer is (no distance between the nozzles)?
Fist of all thank you so much for your help.
I am gonna show you how my printer is.

With your models loaded in Cura and the settings the way you want - use the File | Save Project command and post the 3mf file here. It should be a project that utilizes both extruders.

There are different kinds of Multiple Extruder printers. There are true multiples and the printer will have separate extruders, hot ends, and nozzles for each tool. There are "multiple-in-one-out" machines that have separate extruders but that share the hot end heater and nozzle. Different types need to be set up differently in Cura.
What did you do? Which one describes your printer?
My printer belongs to the first category(true multiples).

Hi guys.
I'm trying to set printing temperature in cura, but it doesn't work. Only the bead heats up and not the printed head. Does anyone else experience this problem?
I loaded the second extruder on Wanhao Duplicator 4s, and then when i am trying to print the extruder does not heat up... -
Hello guys,
I downloaded the 4.2.1 version of cura for my Wanhao duplicator 4s.
I still not able to add the extruder settings. Does anyone fixed this problem?

Hey,
First of all thanks for the help. I noticed a problem.
It doesn't load temperature in nozzle at first.
Also when it moves away to change the material.. at the begging beacause there isn't such a distance between extruder and the build plate.. a lot of material is collected in the nozzle.. so it is created small balls of PVA.. and the nozzle carries them back to the main design and it destroyes my print.
...So should I try to do it with to "enable Prime Tower" with my start/end gcode that i had posted in the beggining?
