Whats the part number for this and for the N-channel mosfet used in reverse power protection (Q2)?</p>

I got a ShapeOko 3 from Carbide3D in October with version 3.2 of their board and got drop-outs half the time I powered down the router. I even tried plugging the router into a differnt outlet and breaker than the ShapeOko, but it didn't help. As soon as the new board came out they FedEx'd it to me and ever since I have never seen it disconnect.</p>

I am using the thermal gap filler but I still get a lockup every single time I shut down the spindle. It happened with my Dremel and still happens with the new DeWalt router. I may be trying an "embarrassingly kludgey oversize filter capacitor" myself.</p>

Carbide needs to do the same thing on their board that they are shipping with the Shapeoko 3 machines. Instead, they have added an embarrassingly kludgey oversize filter capacitor. I suspect it would have been adequate simply to have not shared the controller's ground with that of the router motor/spindle, although I admit that I have not tested this hypothesis. Perhaps they did, and I am wrong.<p>But there are several things that don't thrill me about their controller, so I am considering switching to this one. It probably means that I can't use their software any more, but I think I can live with that.</p></p>

The laser has no lateral load aside from the momentum of the laser itself, so it doesn't make a lot of sense to put a laser on a shapeoko, though I do admit it would be fun.</p><p>The method Epilog uses to make their laser cutters, in which the have 10s of watts of power (and subsequently large immobile laser tubes), is to fly a lightweight first surface mirror around on belts, similar to <a href="https://www.sparkfun.com/products/12156" rel="nofollow">timing belt</a>. This way the mirror can locate quickly.</p><p>The other half of the problem is getting the laser to be on and off at the right times. The stepoko controller has a PWM out intended for spindle speed -- but it could be re-purposed to control the laser power. Special gcode would have to be created, though there may be a program for this.</p><p>Check the <a href="https://github.com/grbl/grbl" rel="nofollow">grbl repository</a> for source and documentation. It looks like the M3, M4, M5 commands are supported with spindle speed being set with an S word, but I haven't used the feature.</p><p>Hope this helps</p></p>

Check your spam folder for SparkFun emails and if you don't see anything email customerservice@sparkfun.com and they should be able to help you out.</p>

Assuming you connect it to a 3 axis gantry like the Shapeoko you can connect anything you want (Sharpie, router, laser, 3D print head, pick and place head, etc.). Check out the video for Marshall's tiny DIY laser cutter (doesn't cut much more than paper because of the laser he used, but it works).</p>

Is the thermal gap filler available and should we be adding it to our machines?</p>
