parametricparts.com announces REST Build Service - 11 years ago
Hi, everyone: We're pleased to announce that we've released a REST build service! The service is simple, but hopefully useful. You do an HTTP post with a script ( or the id of s script hosted on the site ), what type of output you want to get ( STL, STEP, AMF, or Three.js JSON ), and whatever parameters you would like to customize the model. You get back the output you requested. If you woulby dave.cowden - Experimental
parametricparts.com: STEP mashups. - 11 years ago
Hey, everyone: We're proud to announce that parametricparts.com can now do STEP mashups. Load a STEP file ( either uploaded or directly from another URI ), and then modify it parametricly. check out a few examples here: documentation for CadQuery, a fluent modelling language you might like, is here: I'd love to hear your thoughts!by dave.cowden - Experimental
Re: AMF - 11 years ago
Hey, I'm interested in AMF support also. Its _soooo_ much better as a format! No more leaky meshes, ability to specify unit of measure in the files, as well as internal structure, lots of goodies! I'm working on a project that aims to make it easier to make solids in AMF format-- for example What other places can generate AMF?by dave.cowden - Slic3r
Re: Introducing ParametricParts.com: Productivity for 3D - 11 years ago
I'm using three.js's built-in WebGL detector.js, which i guess doesnt know about Waterfox. Basically if you dont have WebGL three.js uses a canvas renderer instead of a webgl renderer, so its much slower. What you are seeing is the same as you'd see in IE. Firefox seems to work well ( at least on windows ). Though i don't have control of what browsers support webGL, honestly my hope is thatby dave.cowden - General

Hi, thanks for having a look! I'm using chrome as well, but on PC. Yeah you shouldnt need any signup or anything: this link should take you to a configurable 608 bearing pillow block: if that still doesnt work you can also go here: and see if one of the others works. I know the site is ugly, i've spent most of my time on the 3d-CAD part. if those still dont work, let me know, i'll seeby dave.cowden - General
Introducing ParametricParts.com: Productivity for 3D - 11 years ago
CONTENT IS KING, ESPECIALLY FOR 3D PRINTING. We have launched an alpha product we've been working on that aims to make it easier than ever to create 3d models. It allows customizing, previewing, downloading, and printing 3d models with your browser. We're excited because we think this tool will change the way people approach 3d. We need to stop searching for pre-build models and start makinby dave.cowden - General
Re: RAMPS firmware (G61/G64 ) --Motion Tolerance ? - 13 years ago
Ah, interesting! Yeah emcs default thread runs at 25us I think. Which approach do you think would be most suitable in the case that we want to handle g02 and g03 in addition to g01? Im still dreaming that someday I will finish my scripts to slice step files instead of crappy stl files, which could produce arcs on perimeters. If I can get that going, then the object designer could contol accuby dave.cowden - Firmware - experimental, borrowed, and future
Re: RAMPS firmware (G61/G64 ) --Motion Tolerance ? - 13 years ago
Interesting-- so the gist of the situation seems to be: "yes, that would be great, but the calculations are simply too much to do in relatively low power firmware, so the proposal is to do trajectory planning in the pc, and then send lower level information to the processor... but there's no great way to send that data in the gcode itself" To me, this is somewhat disappointing-- it means that doby dave.cowden - Firmware - experimental, borrowed, and future
Re: RAMPS firmware (G61/G64 ) --Motion Tolerance ? - 13 years ago
That's good to hear... am I incorrect then that no firmware has implemenred this, or is there a good reason it has not been? Can you point me to some of those discussions? I looked at the links below your post, but they did not appear to contain more info on this topic Thanks!by dave.cowden - Firmware - experimental, borrowed, and future
RAMPS firmware (G61/G64 ) --Motion Tolerance ? - 13 years ago
Hi, all: I'm a cnc hobbiest, and reprap nut. I have been following reprap for years, and have been working on my own repstrap for a while, though progress is slow. I am by no means an expert, but I have built and operated my own CNC machine. I use EMC2 for control-- it is an excellent motion controller, though unfortunately typically in a much less convenient package size-wise than a RAMPS boby dave.cowden - Firmware - experimental, borrowed, and future
Re: Occ Slicer 0.3 is available - 15 years ago
Hi, Ian: Good news-- you are up and running! That error message is just some weird Cheetah thing i dont know how to get rid of, but all worked fine if you get it. The program will end when you close those windows. if you check the same folder where the file you opened is, you should see the _sliced.svg file. In my next big version i hope to drive verything from the gui, so there will be a 'slby dave.cowden - RepRap Host
Re: Occ Slicer 0.3 is available - 15 years ago
Hi, Ian: Thanks for trying it out. Cheetah is an "old school" python module-- they install like perl modules-- you download it, and then run a setup.py file using python itself. This makes sure to install it in the python you use to run the installer. (1) install python first. (2) go here and download the latest version. The file is a tar.gz file (3) open the file and extract it to to a temby dave.cowden - RepRap Host
Occ Slicer 0.3 is available - 15 years ago
I have started a new thread for comments about my step slicer script. I had posted on the skeinforge powwow thread, but moving to a separate one is probably better. The attached script will slice stl or step files, and then export an svg file that can be imported into skeinforge for filling. The script slices quite fast-- and can handle step files for those using commercial software. Slicing bby dave.cowden - RepRap Host
Re: Skeinforge Powwow - 15 years ago
OccSlicer version 0.3 is available. This version has lots of new features and bugfixes: * an installation manual is provided * slicing of stl objects is faster and more accurate * a window is provided that shows slices as they are created, in addition to the full part. * windows are now interactive-- zoom, pan, and twist both windows * added command line arguments to set slice tby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
@JeffB, glad you got it working. Next version, i will fix the wxDisplay issue, put together an install guide, and add command line parameters to change the parameters like slice thickness and such more easily. Hi, 2mm is definitely -not- the best thickness. if you look in OccSlicelib.py, near the bottom, look for this line: sliceSet.sliceHeight = 2.0; and change it to what you'd like. 0.3 mmby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
ITs all hard and stuff to document which dependencies and get them installed. What are you guys' thoughts about whether you'd be interested in: (a) keep it the way it is-- dependencies are no big deal if they are well documented, i'd rather have the software locally. (b) it would be worth the download time of the files to have the app web-based so that you can just use it (c) it would be wortby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Hi, Jeff: No thanks for apologies required. Actually, it should be me that apologizes for posting stuff and not thinking through all the requirements and dependencies. You've run into yet another thing i installed and forgot i had-- Cheetah is a template processing library. you can get it here: Latest version should work Also, check to make sure there is a file called svg_template.tmpl in yby dave.cowden - Skeinforge

Re: Skeinforge Powwow - 15 years ago
hello, all; I have a few people trying out OccSlicer, so I have hosted a copy on my website so that it is quicker for me to post new versions. here's the link: Current version is 0.2. unfortunately, not yet proven to work for anyone but meby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Hi, Jeff: Sorry for the trouble. I see that now-- very strange-- that works on my setup. Try expanding the attached version and see if that works. That line was redundant-- OCC.Display.wxDisplay is the same as the one included so i just removed that line. its hard for me to know for sure-- since it works either way on my machine.by dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Ok, in an attempt to make installation easier, I have attached a new version. in this version, there are these improvements; (1) all files needed packaged into a zip file. Sorry for those who helped me discover missing files ;( (2) included the two STEP and STl files i was using to test withby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Hi, Jeff, thanks for trying it i'll try to help. im not sure where that line is coming from : "from wxdisplay import wxviewer3d' does not appear to be in either of my script files. Can you post the complete error trace and i'll debug. your step file should work fine-- though i think iirc you will need to name it '.step'-- current version posted doesnt recognize .stp. that's an easy fix though.by dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Ok, Sorry-- I got back to my machine to check this out. wxDisplay is part of pythonOCC, but i forgot I was using a modified version of it locally. I have attached this file also-- just put it into the same directory as OCCSlicer.py Sorry to make you pay for my slopiness-- hope this file is the only other one you need!

Re: Skeinforge Powwow - 15 years ago
Greetings, everyone! I have been working for a while on an improved slicer that works with skeinforge. Solidworks exports horrible STL, and coupled with the fact that STL is horrible already, meant that I was having issues getting objects ready for reprapping. STEP is much more capable, far more efficient and more accurate format. I wanted to be able to use STEP to store objects, and slice themby dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Hi, Enrique, thanks. That's kind of a poopy export list-- i'd hoped that my scripts could remove the scourge of meshing parts before slicing, but oh well. I can handle stl, guess that will have to be good enough...by dave.cowden - Skeinforge
Re: Skeinforge Powwow - 15 years ago
Ok, sounds good. Maybe i'll put some comments into the svg file when i know the segment was a curve. I'll also make sure it is possible to control the approximation tolerance. Of course when reading stl this will not be a problem, but for STEP and IGES it will be. Do you know if AOL will export STEP or IGS?by dave.cowden - Skeinforge

Re: EMC2 Based Repstrap - 16 years ago
I think that the notion of "process on host1" and "build on a smaller machine,host2" makes a lot of sense. After all, RepRap _is_ a 3d printer, and thats how printers work. Host 1 converts from the original format into a printer language (for example postscript), and then sends that to the printer. The printer does the rest. If there was a post-script like language for reprap jobs: (1) youby dave.cowden - EMC2
