Another tape to use to stick your prints on

Posted on June 5, 2014 by robertwilkie

The author here writes about using TapeCase 468MP, for your 3D prints to stick too.  Anyone whom has done 3D printing knows bed leveling and sticking are two problems.  Heated beds, special tape (that costs ALOT more than this), some cleaners, … Continue reading →

Fix for Printrbot to use new filament

Posted on June 5, 2014 by robertwilkie

Adafruit made a fix for Printrbots so that you could feed them the new NinjaFlex filament.  NinjaFlex (NOTE: I have not used it myself) is a filament that prints flexable designs.  Seems like a rubber.  However printrbots extruders are too … Continue reading →

Posted on June 4, 2014 by robertwilkie

Pretty extensive list of 3D printers, basic specs, and price.  They also list the availability.  I noticed only printers that have physically made it to folks hands are on the list. http://www.3ders.org/pricecompare/3dprinters/

LinuxCNC Probing

Posted on June 4, 2014 by robertwilkie

I was reading this article during lunch about using HAL in linuxCNC and probing.  Why?  Well its a good way to level the table, or get the height a part is, zeroing out axis’s.  etc etc. http://7xcnc.com/software/probing/

Upgrading a Power Supply for a cheap CNC

Posted on June 4, 2014 by robertwilkie

I have heard on forums in the past that the Chinese CNC 3020 have OK hardware, but the electronics and power supply stink.  The author rebuilt the powersupply to use more robust ones.  These CNC’s run between 500-800 bucks, so … Continue reading →

Posted on June 4, 2014 by robertwilkie

I have seen mini CNC’s made from floppy and CD drives in the past, first time I have seen a 3D printer.  Its a bit funny but if you are on a tight budget, I guess this will do.  The … Continue reading →

Rebuilding my CNC, Part 5 SUCCESS

Posted on June 4, 2014 by robertwilkie

Success! LinuxCNC seems to work just fine, I slowed down my y-axis as I did before so the gantry doesn’t whobble so much.  But I cut the example LinuxCNC in foamboard.  What next?  Time to learn PyCAM

$200 and you get a laser engraver

Posted on June 3, 2014 by robertwilkie

Only if I had $200, nice project build of a laser engraver for $200 that can fit on your existing hobby CNC/3D printer.  Good idea, seems a little pricey for the parts, but its all put together for you. https://www.indiegogo.com/projects/l-cheapo-laser-cutter-attachment … Continue reading →

Build a plotter from printer/scanner parts

Posted on June 3, 2014 by robertwilkie

Seen this a few times in the past, but not this clean looking.  The author basically used CNC to make a plotter.  I like the use of the pencil for drawing.  This would be a good kid project. http://www.instructables.com/id/cheap-nice-and-weird-A4-graph-plotter-25-some-scra/

My CNC rebuild, Part 4

Posted on June 3, 2014 by robertwilkie

Learned another important lesson.  Always make a copy of the documentation of your motor controller (noted below).  Apparently in my move some of the jumpers for micro-stepping must have fallen out.  So what I thought I was using wasn’t right. … Continue reading →
