That's the one I've been looking at...shame would have been an awesome deal.

 

Hmm. The Amazon link is showing more now. HD has it for $116 with $25 additional promo, but out of stock online.
DEWALT 1.25 HP Variable Speed Compact Router-DWP611 - The Home Depot

 

I don't see it apply the discount when input it in the cart. At the bottom it says this item is not eligible. Who knows.

 

totally crazy idea, but I have a cordless Ryobi 18V DC trim router. Just for fun, I may hard-wire in a power supply into an old dead battery frame and see how it does. Cheap DC spindle....

 

Worth giving it a shot if I can find a big enough PS in my stash.

Looks like amazon has the $25 off the Makita too. http://www.amazon.com/Makita-3709-4...ower-hand-tools&ie=UTF8&qid=1449175913&sr=1-5

 

Disregard, that's the smaller Makita.

 

Yeah and it says the $25 doesn't apply to the 701.

 

I have a slightly used Makita 3709 for CAD 60$ if anyone is interested (plus shipping, I'm in Canada).

 

Can someone point me back to the thread or threads on the trades between the Colt or the Dewalt 611? Searching but finding it difficult to separate the wheat from the chaff (lots of results). Also, I'm trying to make sure I understand the collet reducer source for both of these routers. Building a stock C-Beam shortly (on order) and want to research the trades for routers that are readily available to me and that are in my budget.

 

Tool Crib aka the new Acme Tool lets you use the coupon code DEW2015 to get $25 off FYI.

 

Good find. That comes out to $101.48 shipped to California in the cart. Here's that link:
DEWALT-DWP611

 

Sweet ! I will soon be putting a C-beam together ... I twisted my arm and had to give in. Hope myOX won't get jealous ...

 

Decided not to be cheap and ordered my Dewalt 611...$101.48 delivered from Acme. Best deal I have found. Looking forward to getting my build started. Precision collets are a nice option and PreciseBits is a great place to buy and a great resource for info as well.

 

Just starting my build and it's going well. Although I'm still waiting for my DeWalt 611 from Amazon.ca, I've been trying to source a decent 1/8" collet for it. Seems to be difficult this side of the border (Canada). The ones from Elaire Corporation look very reasonable (at $19 USD) but the shipping is $21 USD on top of that.... Anyone know of anything?


BTW ... bought my c-beam parts from "ddman". Super nice and great guy to deal with.

 

Thank you

 

HD has the DWP611's back in stock so I grabbed one. Free shipping, so with the $25 discount came out to $91.70 before CA tax. $99.04 out the door!

 

Yep, good buy. Thanks for the tip, Paul

 

Any thoughts on spinning the z axis c-beam around and bolting the x gantry plate to the carriage plate of the z c-beam? Maybe this has already been suggested or isn't able to be done for some reason? It would give us a lot more usable z. Plus make it much easier to use dust collection since your d.c. skirt would move up and down with the router. You would be a little more cantilevered since the router would be slightly further out from the x but this seems like another no cost potential way to get more area for the same $$$.

 

What is the approximate max cut and travel rates for the C-Beam Machine. I'm using the Nema 23 that came with the kit and running it on a gshield at say 2A. Any idea?

 

That's going to depend on a ton of stuff....
what is the spindle speed?
what chip load are you looking for?
What material are you cutting?
Depth of cut?
Bit design?

my c-beam machine isn't running yet, but on my ox it will zip right thru hdpe but then when I cut aluminum it goes slower.

 

I realize with each material there will have to be adjustments made to feeds and speeds. For example feed/speed calc for cutting aluminum is telling me at my routers lowest RPM of 16k, with a 2 flute carbide bit 50-60 ipm would give me a 0.002 chipload. I would be running at 0.025 step down which is 10% of tool diameter. I would assume the C-Beam Machine with the stock Nema 23 should be able to run at those speeds?

 

Here is what I came up with using Google and the phone calculator. Driving the stock Nema 23 motors with 24v and around 2 amps they should be able to produce about 70 oz-in at around 88 ipm. Does that sound right?

 

sounds kind of slow,
waiting on 100X Female Dupont and Servo Crimp Wire Jumper Pin Header Connector ,US Shiping should be here yesterday!!!! LOL
once I have those I will see how fast I can drive the rapids and not loose steps...
Just had surgery today and I'm going to get bored real quick having 6 weeks off work!!!!
looking at the gcode for the pen examples looks like marc has it set for just under 400 ipm.

 

That is my math based on what I could figure out based on some googling and looking at the small torque map on the stepper motors page on the open builds store. The using some estimations to get an idea. So making a few assumptions and using some guessing if im figuring it out right... I was saying for these steppers at 24v and 2amps if you were cutting at 88 ipm the stepper would have maximum torque output of around 70 oz-in based on the 8mm lead screw that moves 5mm per rotation. Rapids could be more since there is aost no drag.
