Re: Atlas 3D Kickstarted Laser Scanner Now Available

I use a 3D scanner as a part of my day job. Shiny objects and even flat black objects sometimes throw it for a loop. To get past this (as all of the parts we want to scan are metal) we spray the part with a developer used for dye penetrant testing of welds. It sprays on clear and turns a chalky whit...

Re: Simple RPM Detector

If you want to compare your RPM numbers to see how they compare to other 611's out there, check out: http://www.shapeoko.com/forum/viewtopic.php?f=8&t=3918 A live reading would be fun to watch though, just for seeing how much the RPM's vary as the router is running under load. I keep forgetting to m...

Re: Best bits for engraving steel with DWP611?

You can run to Harbor Freight (if you're here in the US) and pick up one of those engravers for about $8 to see firsthand-- but it's surface markings. They basically hammer, they do not mill or remove material, so the markings are on the surface. That being said, I know plenty of people that have us...

Re: Best bits for engraving steel with DWP611?

Myself and another member or two have mounted a cheap hand engraver (the ones that basically hammer the part with a small carbide point) and gotten decent results. You obviously won't get much in the way of depth to the engravings, but I'm not sure exactly what you're looking for. Check out: http://...

Re: Z-axis variation in curved shape

With vectric aspire, you can do a roughing pass that cuts in the xy plane, then follow with a finishing pass that cuts in the xz or yz (or an angle in between) plane. You then end up with ridges based on how big or small your step over/overlap is, but it's fairly minimal usually.

Re: Z-axis variation in curved shape

Those appear to be typical of what you'll find at different levels / z elevations. That is, I imagine that your CNC cut a layer, dropped a few mm, cut the next layer, dropped a few mm, etc etc Those ridges are the transitions between your layers. Yes, your design/file does not have them-- but unless...

Re: E-Stop Issues

I'm not sure if I am following correctly-- it's just hard to see without the parts in front of me. First of all, I noticed that you only have one wire hooked up to your GRBL shield--- keep in mind each axis has it's on pin (one for the x axis, one for the y axis, one for the z axis). I'm sorry I'm h...

Re: E-Stop Issues

If you search the forum for limit switch wiring you'll find tons of threads on the topic and I believe there is also a page or two in the wiki. I'd look there first. Secondly, keep in mind that the limit switches are disabled by default. You need to go in to your GRBL settings and manually enable th...

Re: E-Stop Issues

Are you sure your 5v and GND connections are to your board and not a separate power supply? Are your resistors the right value? That's 10K as in 10,000 ohms, not 10 ohms. Basically it sounds like you're resetting your board by either over spiking it with current or draining all of the voltage/curren...

Re: For Dewalt 611 - How do i use 1/8 inch milling bits"

I use a simple collet adapter from MLCS (about $7?) if I recall correctly and it has introduced negligible runout to my system. My 0.0312 diameter bit (with an 1/8" shank) runs true with no noticeable runout whatsoever.

Obviously your mileage may vary, but a good outcome is entirely possible.
