Support for Flashforge Guider II


Hello, I was wondering if you Octoprint could add support for the Flashforge Guider II. I figure it's possible considering 3DPrinterOS has some support for it. When I try using Octoprint on it, it won't even connect to the port.


It's likely close to the FlashForge Creator Pro. Look at the printer profile thread and scroll to the far right for that definition and read the comments.


Hey Josh, could you confirm that it does work when you set it up? I just got the same printer and am interested in doing the same thing.



@OutsourcedGuru sorry I didn't see your comment (didn't get an email about it) I'll check it out

@Matthew_Woods nah doesn't work. I've tried numerous things I tried getting in touch with the developer who didn't respond so I don't think it'll receive support. I think I read somewhere they tried blaming Flashforge but I've found it works with 3DPrinterOS. So it's something with Octoprint and others (I've only been successfully with one)



Which did you find that worked? What does your set-up do? Can you still operate the printer remotely? Can you hook up multiple Cameras?

My main concern is running out of filament. I wish I had known about the Guider iis before purchasing the printer. The filament run-out detector and on-board camera are amazing features. Anyway to add these to the guider? Alternatives to Octoprint?

(Really, only want to Pause or Stop prints remotely based on errors or filament run-out. I use Simplify3d and print from USB so I don't need the on-board computer/slicer. Thought I'd put two cameras on it. One on the print bed and one on the filament spool on the back. If I notice a print error I want to stop it while I'm away. Or if I see the spool is running out, I can pause the print while away as well.)



Hello Matthew,
I use 3DPrinterOS and will continue maybe until Octoprint add support for the Guider II with 3DPrinterOS you can use multiple cameras, at the moment I got one at eye level of the bed and one looking down at the bed and there is an option for a 3rd camera too (I'm guessing it'll let you keep adding cameras). The problem I've had with 3DPrinterOS is the manual controls sometimes don't work (sometime delay and sometimes just don't work).

What I've done with my whole setup is upon buying my Guider II it came with Simplify3D so seen Simplify3D doesn't have support to connect over the network to the printer I made it so when I click print it'll deploy a script which opens the 3DPrinterOS website so all I need to do is slice the stl, click print (which then opens the 3DPrinterOS website) upload the .gcode file click print again and it's sent to the printer. Sending things to the printer from the website works every time too so no problems with the normally used controls. The only time I've had problems with 3DPrinterOS is when using manual controls (moving the extruder/bed/temperature/etc... manually).

Also with filament runout. My Guider II has a filament runout detector. Yours doesn't? If it definitely doesn't you can always look into making your own using a ESP8266 and lever switch. Then just look up the code, from there you can make it send you an email, notify your phone, etc... (any other kind of notifying method).

In case you're interested in the same Simplify3D setup I used, put this "cmd /c start" (without the quotation marks) in the post processing text box in the scripts tab.

At the moment I'm printing something that's going to take about 2 hours so when it's finished I'll try printing something smaller and try out pausing it and stopping it. I'll let you know what happens.



This may be getting off topic and I apologize, but how do you get the guider ii's filament run-out detection to work? My printer runs through the filament and then continues printing without filament. Even worse, i have to remove the cover housing and extruding motor to pull out the small bit of filament left in the hot end that couldn't be pushed through. I've only ever owned a Wanhao Duplicator i3 and am not familiar with how the Flashforge Guider ii really works in and out.

Thank you!


I don't know how to get the Guider IIs filament run-out detector to work. My Guider II just worked. The only thing I can think of is maybe you have an older Guider II model because for instance I used to own a Finder which supposedly come with a run-out detector but mine didn't. So maybe yous doesn't have one, it's located on the back a little black rectangle.
