Recore and PrintrBot Mixtures

This is a Recore Board w/ a PrintrBot 1403 machine printer and...

The Recore has many things about it that make it superior to normal operating procedures but please look at the video on an older PrintrBot 1403 coming back to life!


I found some nice 3D Printing details online recently and I thought why not share?

So, I went to Ultimate 3D Printing Materials Guide | Simplify3D for a guide on filament types, how to use them w/ or w/out a heated bed, and what is available in print quality these days.

So, I looked around and found their site. Expensive and not open source. I know but they provide some info. on ideas like some other sites out in userland. 

Also, I found another site that has tons of information on 3D Printing, some general and some specific. Here: Gaps in 3D Prints: How to Fix & Avoid Them | All3DP is a page on their site that handles gaps in extruded plastics on the print bed. It basically shows some ideas on how to alleviate the issues of sparse lines and actually, they are saying that it may have something to do w/ the Z-offset. Interesting.


The finished project was better than okay but not to my liking, i.e. so! I will have to print again with CURA as the slicer but this time, there will be some options discarded and some new ones picked.

  • Stringy PETG and PLA in a Comparison!

    silver2row07/16/2022 at 03:05 0 comments

    I have finally learned how to print in PETG w/ my older model printrBot 1403. I am using the Recore board still w/ Klipper and OctoPrint. Things are going okay but I find that:

    1. While printing in PETG, unlike w/ PLA, the prints that build incrementally outward w/out a sound base tend to string out. W/ PLA, unlike PETG, the building of new layers outward tend to adhere a bit more. This entails a solid base per layer when building. PETG is stringy and creates a solid foundation but when there is no foundation, the layering builds upward, even w/ a half a layer build upward, at a non-valid use output.

    The output is basically wired in looks and has no real use. Sanding!

    CURA Slicer for the Recore, PrintrBot Simple Metal 1403, and Refactor


    Use 50mm/s print speed on the CURA slicer with a travel speed of 90mm/s for Refactor 3.0.3 versioning on the Recore A5. Some items have changed in the printer.cfg file that is available/not available any longer.

    So, chose wisely and correct for your particular type of printer. Printers are sometimes strong, fast, slow, and/or weak. But, in the end, the settings and configurations of your target source, slicer, and config. file make or break the print. 

    With CURA, I have learned to test out print speed and travel speed the most while slicing different projects for the Recore. I use the Marlin Flavor in the CURA software along with the custom FFF Printer option. 

    Even though the PrintrBot Simple Metal is an option from the long list of printers, it is a non-working effort with my specific controller(s), software, and slicer. So, I use the FFF option that I can make for a custom version.


    Building is not always so straight forward and it takes time, patience, and a sort of knack for things if you are new to 3D Printing. What seems to not work at first is not an omen that things will never work. Trust in your excellent methods of note taking, forward progression, and learning abilities. 


    P.S. Here are a couple photos. Enjoy.

    The first photo is obviously the CURA slicer getting ready w/ the right side of the photo showcasing the options of that slicer.

    The second photo is the Recore A6 and its peripherals, location of the pins, and so on...

Finally tuning adjustments in my slicer CURA source and on the Recore via klipper should make for some wood craving ooze to be made. I have never printed in wood type spools. I cannot wait. Send rations.

  Are you sure? yes | no
