Hey disneytoy, I actually made a nice time lapse video of it printing. You can watch the video here:by Jim - General New Machines Topics
Thanks everyone! The post is now up on my blog with more info, pics and a time lapse video of the build: http://www.grassrootsengineering.com/blog/2011/09/08/the-big-3d-print/ @rhmorrison - that would be a cool use for it, but was not my original intentby Jim - General
I recently printed what I believe is the largest single part printed by a scratch built RepRap based 3D printer. The part measures 376 x 376 x 250mm [14.80 x 14.80 x 9.84in] and took just under 2 days to print with a .25mm layer height. I'm working on a blog post now with more info, specs and pics as well as a sweet time lapse video of the entire build. Here is a picture of the part with a deck oby Jim - General
I am quite certain the STL is not the problem here anymore. It was fully healed. A G-code file of this size is to be expected because the part is quite complex and is very large (approximately 400 x 400 x 320mm) The problem now is finding/modifying software that can handle sending all the commands of a gcode file of this size to a reprap motherboard 1.2 running stock replicatorG firmware.by Jim - General
Hmm I tired using send-gcode.exe, but it does not work as I don't yet use the 5D firmware. I am currently running the stock ReplicatorG firmware. Is there anyway to use with send-gcode.exe with the ReplicatorG firmware?by Jim - General
dazed.dnc, you were correct, my large STL had a number of holes and self intersecting faces in it. I fixed it completely with netfabb. I sliced it with skeinforge and it worked great! It created a huge 68mb g-code file. But now I have another problem ReplicatorG just hangs when I try to open this massive g-code file. It seems as if there is a maximum file size that can be opened. I tired copy anby Jim - General
Hi Tramagust, I am currently trying to slice single stl models that max out the build area of my machine (400 x 400 x 320mm) with skeinforge/replicatorg. I am running into some out of memory issues slicing parts that large and I am trying to figure out how to go about this (see thread). This would definitely be an issue with 1m^3 parts and is something you should consider.by Jim - General
@dazed, I believe it could be that my stl had holes in it. I tried using meshlab and netfabb to fix them but I still received the same error message. I am currently slicing a dumbed down version of my model of the same 400 x 400 x 320mm size. So far it has had no errors and has been slicing much longer than the original model, even though it is going very very slow. If this fails, I may try usingby Jim - General
Thanks for the tip. To test, I changed the page file size on my C drive to 20gb , but I still get the same out of memory error around the same amount of STL slicing time as I did before. I will try making a second pagefile on a different hard drive. But are you sure this isn't some sort of a python memory pre-allocation problem?by Jim - General
I have been trying to use ReplicatorG 0019 w/ Skeinforge in order to slice up a very large and intricate STL that is approximately 400 x 400 x 320mm. After around 16+ hours of compiling , I get the following out of memory error in the ReplicatorG window: [11:31:29] Traceback (most recent call last): [11:31:29] File "skeinforge.py", line 346, in [11:31:29] main() [11:31:29] File "skeinfby Jim - General
Hi Sebastien. I am not quite ready yet to start a wiki page as my machine is still a work in progress. I don't really have parts lists, CAD, etc. together at this time.by Jim - General New Machines Topics
Thanks Rich! Yes the entire bed is heated, and it uses around 480W. A zone heating system is on my to-do list to lower power consumption when printing small parts. I'm using 3/8"-8 two start ACME Threaded Rod on the X and Y axes and 3/8"-12 single start on the Z axis. Print speed is not too bad, the X and Y axes move at around 20mm/s. I will be increasing this a bit once I get some higher outputby Jim - General New Machines Topics
I have recently launched a website/blog for my large scale RepStrap: www.GrassRootsEngineering.com More pictures of my machine can be found here: http://www.grassrootsengineering.com/blog/mymachine/by Jim - General New Machines Topics
Has anyone had any luck getting an encoder to work with the extruder firmware and ReplicatorG? I am currently trying to get ReplicatorG 0017 to work with the magnetic rotary encoder 1.0 board connected to the Extruder Controller v2.2 . I haven't had much luck modifying the ArduinoSlaveExtruder firmware 1.8. It seems that most of the code is there, except in the Timer1.cpp file as sam0737 noted?by Jim - RepRap Host
