I am mostly building planes with the foam. I was also concerned about moisture but from my wet sanding experience I can say that I have observed no adverse effects.

The cuts need not be very...

lol calm down.

I am planning just to mist the surface so that it prevents fine dust from going airborne.

I don't think that much humidity will cause any rust given that I am running the...

I am planning to do some foam cutting.

I want to prevent the fine dust. Larger chips are fine.

I am planning to finish rough edges by hand so I don't need very smooth cuts.


I was...

I'm interested in cutting foam I was searching for some foam cutter kit having size around 30-40" x 15-20" x 15-20".

The frame (no electronics, if accepts nema 23 steppers it will be great) should...

So far im pretty happy with makita.


The main problem is finding a collet adaptor for 1/16 or better 1/32" bits. Any one know a place that sells adaptor of those sizes ?

thanks.

Basically I agree with Mangus again.


Grossmanator, I think there is a misunderstanding here.

When I was saying I could get over 200ipm easily I didn't mean to say that I am using the...

I agree.

Mangus, So far i machined some small parts at 50-100ipm and wd40 seems to be working good, I will see if the noise will be back. I expected a thicker grease to work but since these are...

Take one stepper out of the machine and see if stalling still happens when it turns freely, it may be the result of insufficient torque but not because 282oz/in is insufficient(you are not cutting...

20000 is the correct value, however your kernel speed is low(since the maximum number of pulses is directly proportional to the frequency). you said you are loosing steps, are the steppers connected...

Hi Grossmanator,

I think it would be better if you also give the system you are using. It may be the driver, the power supply or maybe you are forgetting to run them with a higher kernel...

thats great, So wd40 solves the issue. I always thought a thicker grease would be better. You apllied it only on the mill and nuts not on the shafts right(the shafts seem to be properly working).

Thanks grossmanator,

The frame is the same as yours (2514).

I'm using G540 gecko drive with 381oz-in steppers. Using Mach3 to drive them(and it was painfull to adjust simple offsets in mach3,...

Hi, It was an interesting thread, I read it before my purchase hoped that mine would not have the same problem. But at high speeds(Im talking about 100ipm, although my drive and steppers could pass...

Hi fandz sorry for the late repsonse. The diameter should be around 3.2".

Here is a picture showing it mounted.

The router is much quieter then I expected, at 8K rpm it is quieter then a...

Ok here is another update:

I have received every piece a few days ago.

Gecko G540, 3x keling 381oz-in steppers 48v 7.3A psu etc.

Cheap serial cables came with very thin wires(26awg at...

It is nice to hear that, I was thinking hitachi may be quieter. Hitachi seems like a great router and very nicely priced. It is just that I like Makita brand more and saw that their tools were always...

Thanks a lot for the advice guys.

I purchased the Makita rf1101. It is 50 dolars more then hitachi but It seemed like a better choice then Hitachi.

Hi,

I know the mechanical parts at hobbyist level, fortunately there are people with far more knowledge who can help you here.

The machine I got is the KT 2514 version. To be honest the frame...

ok.

Puchased a GEcko g540 and it is on its way.

Purchased 3 x 381 oz-in steppers and a 48V 7.5A psu from Keling. I didn't purchase g540 along with them since and additional 20$ shipping was...

Thanks for the suggestion.

16$ for a 12 foot 20awg wire seems expensive.

I think I'll go with those cheap 6-10ft 22-24awg serial cables.

Ok, My machie arrived and it looks good.

I didn't have internet for the last 3 weeks(I'm still quite angry about it ) and there were the holidays so I couldn't buy the driver, steppers yet.
...

Jeff, the spindle you suggested seems to be a quiet solid spindle but with a vdf included its price is nearly 700-800 which is I think quite expensive.

I used to build rc planes so I used...

@ fandz: Ahaha, that's messy. Thanks a lot for the photo.



I looked at the specs and found out that rd1101 has 81db and Hitachi 79.5db noise levels. Both are comparable to an average vacum...

Thanks a lot Ger.

I read that explanation about gecko outputting 50V and 381 run optimum at 50v , makes sense. However I have seen lots of variations. Kelling sells 380, 382 oz nema 23's and there are no torque curves...

Your recommendation is nearly what I choose. Thanks a lot.

Why 381's are better then 387's? I can't seem to find the torque speed curve for 381.

How about 425or 495 steppers ?


One more...

You and Gery are right I'd better solve the dust problem.

I was also looking for a way to make an easy enclosure for the machine. Your idea seems pretty easy and solid. Do you have any picture of...

Thank you ll for the great replies.

I had one of these "green" series Bosch router and it was screaming like hell.

After two years I'm returning to cncs.

Since I no longer possess the time and place to build a cnc I just purchased a 2514 K2cnc.

Now I'm trying to figure out which router to use with the...
