Re: Thermal “goo” suggestions for replacement CM board on SO3

Do search for heat sink grease. Also any thermal paste used for Computer CPU's will work. Most heatsinks are aluminum so you will not have to worry about the pastes eroding it away. Some of the pastes are conductive so be careful not to get it on the electrodes or the board. A little bit of this goe...

The RoadKill guys have shown this method for Spark plug wires, Just never thought about doing something like it on my CNC wiring. Good Tip.

Re: Cutting oversized stock

You have to build points into your design to use as index points so that you have a know set of points to start the second half of the job. I've seen some folks us pins (dowels) on the backside with corresponding holes in the bed. Others have 2 or 3 points in the design that they line the bit up wit...

Re: GrblGru = Free 3D-Simulation for ShapeOko2

Leonardo, Just because Grbl doesn't support the G41 and G42 doesn't mean you can't get proper parts out of your lathe. It means that the cutter radius (diameter) etc can't be compensated in the controller. But if you calculate the compensated path in the design software before you generate the Gcode...

Re: Flood Coolant on a Shapeoko 3 and Plastic Waste Boards

also do a little research on the coolant that you are planning to flood the cut with. Some coolants can cause increased oxidation in some metals (I'd say rust but that would only apply to steel). This is not going to hurt your parts but might cut down the lifetime of your router or other parts of th...

Re: XXL Projects for Junior High

I made some simple toolboxes with some 5-7 year olds. For them I had all the parts cutout and they assembled them. I used a saw to cut the blanks and Shapeoko to personalize the ends but with older kids the whole box could be CNCed. to add difficulty you can add box joint construction. With the pers...

Re: Miss Cuts w/3D Cutting

While your checking every thing will Mentioned it's a good time to check and make sure all your set screws are tight. It's a good practice to check them every so often, especially a few runs after you set them for the first time. Locktight helps but if they are a little loose cutting makes them loos...
