Which software are you using?
Simplify 3D is really good investment from my perspective. I tried many freeware program and decided to buy simplify3d and print quality had a sharp increase.

Matt,
Can you tell us about the slicer and slicer settings you used for both prints?
Anthony
Right now I’m using the Sailfish Replicator G software that came on the SD card included with the printer.
I also printed via USB connection, as opposed to the SD card. I’m wondering if that would make a difference…?
Hey Matt,
your biggest problem, the “banding” is simply a matter of increasing the resolution, aka. layer height. Your flashforge print looks to be on the order of 0.3, while the makerbot print is probably 0.2 or slightly less. You should EASILY be able to change this in your slicer.
The parts that “simply didn’t print” can be a result specific to the slicer you are using. It is a little hard to tell ffrom the pictures, which features you exactly mean, but I myself had embossed text disappear between one and another slicer. I don’t know what flashforge recommends for their printers, but you could try Cura for comparison, it’s free.
For a cleaner, stringy-free print, try lowering the print temperature slightly (in 5°C increments). Additionally you can increase the retraction distance by a bit (I’d suggest 0.5mm increments). If you go too far with the retraction you risk a hard to clean hotend clog, so be careful.
Hope this helps,
Jonas
I tried that with my mac and it was really trouble for me. Therefore, I decided to have an alternative.
I am using PLA more since the results are better, no bending layers. 180 C for nozzle and 60 C for the bed. Layer thickness is 0.2 - 0.5 depending on the fast. Software-wise and easy to use, I really recommend people around me to invest a bit on software side. Flash forge is not the most expensive 3d printer but with some software steroids.
Matt,
Printing over USB might make a difference, but I bet it is your slicer and slicer settings. Try printing from the SD card to make sure it is not a USB data transfer rate problem.
You should download the newest version of the makerbot software. MakerBot CloudPrint: 3D Printing Software | MakerBot 19. It will work with your flashforge.
You could try slic3r or cura we well. These guides can help.
I would recommend the simplify3d software as well. I think it is a good investment.

Hey Anthony,
Thanks for the reply! I’m away from the printer right now (I’m at work, it’s at home), so I’m unable to check the slicer settings. But, I can tell you that I didn’t change ANYTHING from what would’ve been the “factory settings” it came with.
This might be a dumb question, but what’s the difference between the “slicer” and the “slicer settings”? I’m still a bit new to 3D printing.
Thanks for the help!

Hey Matt,
Since all of my printers use exlusively .gcode files, I’ve never had to fiddle with any conversion. So I can’t give you any input on that. What I do know is, that there are plugins for Cura, that should allow you to output .x3g files. The Ultimaker forums (makers of Cura) or just Google in general should be a good source for this. The plugins are also really easy to install, once you have Cura running. Just be sure to use Cura versions 15.4 or earlier, the 15.6 versions and up are only for the Ultimaker 2 family of printers right now.
Sincerely,
Jonas
The thing that I have found makes the most difference is your speed. My default settings in Replicator G were way too fast. On difficult prints, like spheres, I’ll slow it down to 24mm/sec and a travel speed of 30mm/sec. Simpler shapes can go faster, but I rarely go any faster 48 & 60 mm/sec
You should never print with a layer height that is more than 80% of the nozzle width, otherwise your interlayer bonding will be seriously compromised. The largest practicle layer height for a FFCP with the stock 0.4mm nozzle is 0.3mm.
If you try to print with say 0.4mm layer height, you will have virtualy no contact between the two layers, its like two 0.4mm cylinders laying ontop of each other, there is only a very thin strip of contact where the circumference of the plastic that makes up the layer touches each other, printing at say 0.3mm means that each layer is pushed 0.1mm into the layer below it, which flattens the bottom of that cylinder, and significantly increases bonding. If you tried to print at say 0.5mm with a 0.4mm nozzle the layers would theoreticaly not be touching each other and the print would fall apart.

These settings seem to also be helping my prints a lot. But have you figured out how to switch extruders in Makerbot desktop? I can only seem to get prints using the right extruder. I changed the “defaultExtruder” settings to “1” and also clicked on the Object information and switched to the other extruder, but it still only prints with the right one! Any help would be awesome!!
