Re: Carbide 3D's Blog:Say goodbye to MDF. We love this new t

Best to use mic-6 cast plate instead of 6061, it will be flatter and more stable. It is the most typical type of aluminum for tooling plates, and is similar in price to 6061 as well.

Re: Another Dial Indicator Bracket

You could make a swivel version, so it always stays on the machine. Ball detent maybe. Repeatable enough in Z.

Re: Thinking of replacing mdf wasteboard with T-Slot Alumin

I've found a regular table saw works well enough to cut extrusions, with copious WD-40. You could always use the machine itself to make holes, slots, and counterbores... Might be hard to put them in the right places, though. Maybe measure, center spot, and drill the holes just .03" deep using a .125...

Re: Upgraded to 9mm wide belts

It's true the Shapeokos would benefit from a 3:1 or so torque/speed exchange. A smaller pulley does work in that direction, though not by a whole lot. The trade-off is that you can't use small pulleys with larger, more rigid belts so you're stuck with the weak stuff. And the MXL belts were prone to ...

Re: Thinking of replacing mdf wasteboard with T-Slot Alumin

I would dry and seal the MDF, then attach the extrusion to the top of it because it would make the whole job very simple to do. You would lose some Z travel that way, though. I think the metal underneath the MDF is what gives the machine its strength, not the MDF itself, but regardless the aluminum ...

Re: 3020T CNC Arduino/GRBL Conversion

You call the driver chips upgradeable, but aren't you limited to 2.0 A no matter what with that board? With grblShield/TinyG you can do 2.5 A though you can't upgrade that either.

Re: Another Dial Indicator Bracket

Good idea, nice execution. Has a stock look to it. I might go for a brass- or plastic-tipped set screw to avoid marring the indicator shaft.

Re: Beginer Machining Questions with Shapeoko3

Something you might not be aware of (no offense if you already know) is that inch and metric flat head screws take different countersink angles. If you use inch screws, you need 82 degree countersinks, but metric can use 90 degree which usually means you can use the same tool for those and for your ...
