Flasforge Creater Pro (Replicator 2x clone) G-Gode Settings

[Cordvision]

Hello

I just bought a Kisslicer Pro license and I'm struggling getting it to work with my Flashforge Creator Pro.

I'm using the Sailfish Firmware (v.7.7) and the GPX post processor.

My goal is to be able to choose the left or the right extruder for printing, or to do dual extruder prints (using PVA for support). 

Is there anybody that has working settings for:

G-Code --> Prefix

G-Code --> Select Extruder

G-Code --> Deselect Extruder

G-Code --> N Layers

G-Code --> Postfix

I used kisslicer previously a few times with a Solidoolde printer which worked fine but I'm having difficulties getting it two work with my new dual extruder printer and I just can't find a whole lot of information about this topic.

Any help is greatly appreciated.

Maybe you can take my post about the Rep1 Dual / settings  as startpoint. Take the Replicator dual Makerware version when using GPX.

https://groups.google.com/d/msg/kisslicer-refugee-camp/Qp4GkDmtJL4/91s5x0IxW1QJ

Basically, the Rep2X doesn't work that much different than the Rep1dual, but I have checked the used codes by the 2X and inserted them below.

Be sure you use at the Printer//Firmware tab the Absolute E no reset (Makerbot) type, and check the fan codes (but AFIK the Rep2X is using the M126 and M127 command to switch the print cooling fan.)

Under Printer//Extruder Hardware: assign Axis 1 as "A" and Axis 2 as "B".

The only thing I think to remember that someone had a problem that the Extruder Fans weren't switched on. It should be working with this Gcode, but maybe keep an eye at it when starting the first print. (With me they are starting when reaching 60 degrees, as it's hardcoded in the firmware).

See below for inserted Gcodes

First of all, thank you very much, it is helping a lot. I started customizing a start code a little bit and I can't figure out some g-code issue. Here it is:

; **** end of start.gcode ****

The red marked g code in kisslicer results in the following g-code output: 

M104  S220 T1 (enable to set active tool to main temp)

M133 T1

What I don't get, why does it replace T<EXT+0> with T1? I read on the kisslicer gcode wiki that the Token EXT is by default 0 (right extruder) so I would expect it to translate it into T0. What am I missing?

[funBart]

No, it takes the token it thinks it's the active extruder, it's only default to T0 when only one extruder is set. BTW: the token <EXT> is resulting in T0 as well.. 

Is it so that the first chosen extruder after the startGcode is T1? Than it''s normal Kisslicer behaviour.

I would recommend to use T0 and T1 (and not <EXT+1>) in the startGcode, so you can predict the behavior better.

You realise that the line:

G1 X90 Y-73 B24 F2000.000

is priming the left (T1) extruder normally? But I think GPX is that translating ok again to x3g code.

I assume the way the Gcode now is presented is because of copy/paste?

As normally the comments belong on the same line.

so not:

G1 X90 Y-73 B24 F2000.000

; extrude a line of filament across the front edge of the bed

but

[Cordvision]

What I don't get is why the active extruder is T1 and not T0. In the starter code I call for "M135 T0; load right extruder offsets", and that is the only time I'm calling for an extruder directly, after that it is always with the Token EXT. The "Select Extruder" code is this:

((**** Select Gcode extruder change***)

M135 T<EXT+0> (toolchange)

M104  S<TEMP> T<EXT+0> (enable to set active tool to main temp)

M133 T<EXT+0>

; stabilize extruder temperature

The g-code after the Starter Code and Select Extruder Code is as follows:

M126

G1 X14.72 Y1.12 Z0.5 B0 F9000

G1 X14.72 Y1.12 Z0.35 B0 F600

G1 B1 F3000

G1 X0.12 Y15.72 B2.8928 F2064

......

It uses extruder B for extruding (in the main code as well as in the start code when it is priming the extruder) , so does this make T1 the default? I always thought that the printer just reads the code from top down, but this would suggest that it reads the main body of code first to set the default, is that correct? 

Second question, you said:

You realise that the line:

G1 X90 Y-73 B24 F2000.000

is priming the left (T1) extruder normally? But I think GPX is that translating ok again to x3g code.

Yes, it primes the left extruder, should it not?

Thanks for the help :)

[Bart]

Yes the Gcode is read line by line.

To be sure: do you have setup a profile with one or two extruders under Printer//Hardware?

And if so, what are the axis set on the extruder//hardware tab?

Because I don't understand why your code after the startGcode is without M135.

The change from A to B is only applying to the extruders, so when A: the right is extruding and when B, the left is extruding. But the printer has to do a Coordination switch as well (as defined in the firmware), by which the coordinates shift about 33mm, by the M135 command.

Maybe it's the best to post the zipped complete Gcode and the ini files used, so I can reproduce the problem.

Yes, profile is set up with two extruders, and I can actually print with the left extruder even though I have all these difficulties with the G code. I attached a zip file with all the files. 

On a side note. If I format the comments properly, it messes up the g code. It puts all codes on the same line -->

(**** Flashforge Creator Pro start.gcode****)

M103

Not sure what is going on here...

Thanks again for the help, I really appreciate it. I really made an effort to get this sorted out on my own (was reading up on messages boards all day long) but I really can't figure out what is happening here.

[Cordvision]

BTW: Just occurred to me. Could this have something to do with the fact that I'm using the latest Beta version of Kisslicer?

[Cordvision]

One more thing: I did change the Start code in the attached zip file already from what I initially started with. Originally I used M135 T0 right after homing, nevertheless the active extruder was still T1 (when I used T<EXT+0>, it would translate to T1 and not T0 as you would expect). I now changed the code after  homing from M135 T0 to M135 T1. 

The way it was originally (M135 T0) I would expect to get T0 for each T<EXT+0> that follows it.

[funBart]

Hi, sorry it took some time to get back to you: as for your question:

I tried your T1 profile for the printer, and for me it's ok: Kisslicer puts T1 for that tool, as it's the only active tool for Kisslicer, and the first one to be used. Maybe I don't understand it yet, but when using EXT 2 (on the Printer//Extruder tab) as the only or first extruder to print with, as far Kisslicer concerns it's actually T1. So <EXT+0> is always resulting in T1. Kisslicer isn't aware what you write in your startGcode, it just copies it and fills in the tokens (if any). So whatever Extruder change or code you put in the Prefix / StartGcode fields: KS won't 'do anything" with it.

When you want to put T0 at that line, just give T1 or <EXT-1>.

About the lines of the startGcode on one line with comments unchecked: that was a very old bug, but for what I know it was fixed. It was caused by the way line ends were described wrong in the *.ini file, 0A or 0X0A, don't remember it anymore. A workaround wast to copy it in a texteditor in some weird format, and export it, but I don't recall how anymore.

Maybe you can report this as a bug in the Beta thread, as I wasn't able to fix it either for you.
