The equations and solution presented is by no means the entire equation or forces needed to size motors...but cutting forces are something that one has to consider in order to properly size the...

So.... I thought up a very simple (likely conservative) method to estimate cutting forces so some of you can size your stepper motors accordingly.

This question has been posted time and time...

To my understanding the Keling drivers are made by leadshine.

I also found out the G540 is digital.....but if what you're saying is true (DSP vs CPLD) the question still stands.

Performance...

I think the drop in resonance from the digital drivers is due to the fact that they're not analog like regular drivers...They also generate much less heat in the steppers than analog drivers.

Is...

So my build/progress can be seen here:
Although it's a little out of date.

My question is if anyone has experience with both sets of these drivers...

Hello I think I'm going to be ordering this kit this week - but I have a question...Would the KL-4042D not work for those same stepper motors?

The regular 3-axis kit uses the analogKL-4030 which...

Do you offer a 3 axis stepper motor kit with digital drivers instead of analog drivers? Specifically the 381 oz-in or 425 oz-in motors?

Thanks.

Really cool....Very very clever idea!

Do you offer any multi axis KL digital drivers?

Do they all incorporate their own power supplies?

Yeah that's not a bad idea, thanks!

So I slapped together my design for a integrated stand. Its made of 8020....I am a bit concerned with the CG being too high now though. But I think after I add a reservoir for for the spindle's water...

Most of these parts were made inside a machine shop with full sized mills, and lathes... Aside from that, Some pieces are designed with oversized or ovaled holes so that adjustment and fine tuning...

Thanks for this info! I bought the stuff and applied it and it seems to be holding tough, but the true test will come when I have motors in my machine!

So here are some pictures for this slow...

So here is the newest image with a decent camera. As i've said I've got the lead screws turned down - however on some of them i turned them down a little too much...

Yes - sorry for the long time with no update been busy with school.

I've assembled most of the Y axis and machined most of the plates needed for it.

I've also turned down my ACME screws... Here...

Hmm I see your argument.. Makes me wonder if I should perhaps go with lower TPI screws so i can gain some speed.

Why do you say that?

I was planning on using 10TPI screws, and my .0005" are with no micro-stepping.

Details of my machine build are here ...

So i've searched and searched and search and can't seem to find a quantitative answer.

My machine is designed to move .0005" per step on a motor -- I'm hoping this is achievable with ACME screws...

Anyway, this week i managed to drill the holes into my linear rails so that they'll...

Yeah the tapped holes in the acrylic are my main worry too -- they're pretty weak...I figure they should last long enough to make aluminum ones once my machine is running...but until then.

Hey thanks for the comments.

I've done a bit of calculations for the acrylic parts and since the acrylic parts are mainly just going to see loads normal to there surface.... The young's modulus...

Displacement while making x-axis cuts...

Are you talking about the bearing size on the Z axis, yeah I realize those bearings on the Z are too small?

You still think i should hold off on cutting the main upright tomorrow? I'm only on...

Under each of those bearing blocks is 2 bearings, the blocks are around 4inches long.
