204r + Electric Dompteur = Awesome

Just finished my 204 and thought the NLM Electric Dompteur might work well to control it. Well, I was right. It's like a match made in panning heaven. Thanks NLM!

Oh nice. I'll have to see if they have those in .005" tip too. .01 is cool, but I'd prefer to try an approximate square font corners a little more of possible. More passes of course tho. :-/
they do. that’s the smallest one they make i believe.

Re: Making your own panels with a desktop CNC

incidentally they describe their marking cutters (2-flute) as being stronger than their normal engraving cutters. i've had really good results (both in part finish and tool durability) with 0.010" tipped-off engravers. i might try a marking cutter to see if i can move things along a little faster...

Re: Making your own panels with a desktop CNC

well, tip diameter is only one piece of the puzzle. included angle (ebay listing says one thing, image of item says another) and depth of cut are critical too. but yes, if your tip diameter is not what the machine thinks it is cutting with then your shit will be all kinds of off. for this kind of mi...

Re: Help Programming ATtiny84A

The Waveshare AVRISPmkII does not supply 5v to the chip so the chip is being powered by a battery & 7805 reg. Tried it both ways - power connected from protoboard to programmer and power disconnected. No change. I've had these work before (that is I've flashed chips) just not on a protoboard. Depend...

I'm having a hell of a time getting a .hex file onto this damn chip and the main problem is that I have no idea what I'm doing. So far I've tried: PC and Mac, Atmel Studio, AVRFuses, AVRdude (via command line), USBAVR V3, AVRISP mkII, internal clocking, external clocking, power supply to chip via US...

"Putting marks at the physical ends of travel means they're inaccurate."

Re: Making your own panels with a desktop CNC

Anyone have any thoughts on replacing a trim router with a real spindle? In terms of size/hp/rpm . I’d like something of at least the same performance but with the benefits of less runout and less NOISE! Thanks Steve I did just that on my MillRight machine. Water-cooled spindle for noise abatement....

Re: Making your own panels with a desktop CNC

Oops. Clobbered another bit. This is a mistake I've made a few times, I run the job, then after the machine returns to zero I jog it out of the way. In this case I wanted to rerun the job just to see what happened but ran it from this random out of the way position. The results speak for themselves...

Re: Making your own panels with a desktop CNC

Re: bow in the panel - you'll never get it to cut correctly with that much concavity at the depth/resolution AND the gear you're currently working with. I know nothing of mapping the Z or buying a special spindle/adapter/whatever. Your easiest option is to work out how to get those panels to lay fla...

Re: Making your own panels with a desktop CNC

your lines are cleaner on the left relevant to the right so the first thing i'd suggest is either surfacing your spoilboard or ensuring that your workpiece is flat against said spoilboard. that the letters are thicker on the right means that the cutter is digging in deeper on that side. the squiggli...

Re: Making your own panels with a desktop CNC

Blanks, dowels, expensive metal sticks...whatever you wanna call em! They're functioning as locating pins for this application. KSS is right: they need not align with your X or Y but since I've got a pretty big work envelope it just keeps it simple (and I like simple). Since they started life as 1/8...

Re: Making your own panels with a desktop CNC

Like this (although technically they're not blanks...they're endmills I've destroyed. Lop the sharp end off and now you have a blank. Also good for zeroing your X and Y). I’m cutting my own panels (as opposed to shearing) so I’m certain they’re square. You can do the same thing on the X if you’re cr...

Re: Making your own panels with a desktop CNC

quick tip about getting your panels perfectly square relevant to your X/Y travel (and hence not needing any time to adjust the panel prior to the glue curing): drill two holes 3-4mm deep in your Y axis about 50mm apart (or whatever...as long as the distance is LESS than the height of the panel you i...
