Hi guys. I just received my k40 and sure backup everything you say about the software. I haven't had it long enough to judge much about operational problems, but the flow is horribly convoluted. I'm...

I'll second that! Unless that support hardware costs more than paying for the "correct" size parts. :) Those are some awesome servos!!

All that except the steel sounds great and very do-able. I think your weak link will be the belts. Particularly when you try steel - you just may strip the teeth right off the belt. I'll tell you...

Hi Gerry. Do you really run your router at 4 meters a minute? I'm using 5 start 1/2" acme screws on my plate maker which I think is around .5" per revolution, so I think that's in the same ballpark +...

Fixtureman1 - Sorry I didn't get your vid. they are blocked on my phone. Now I'm home and could see it. Thank you and I'm wishing you a Merry Christmas! And thanks for your musical addition to my...

I certainly agree that steppers do generate harmonics, but this is at all speeds except if I move one stepper at a time at the fastest rate possible. At any normal cutting rate the sound in the video...

It's all three. In the video it's making a 3" circle with the z axis moving up and down 1".

Hi Guys, I've been working on a new build that's got a issue I haven't ran into before - it's moaning when running the steppers. Take a look;

I'm looking forward to seeing your pics whenever you can get them up.

I've been having the same problem with my posts requiring the moderator to check. It must be some glitch in the system unless...

Great! Thank you very much.

One last question, if you don't mind. just what should the rating for the braking resister be? I'm not sure I'll add one, but there have been times that I've wished I...

duplicate post - sorry

Those stronghold tables are SWEET! And all the rest of that stuff is pretty nice too. Congrats!

I wouldn't worry over people that have a different agenda. Jealous maybe, I know that if I were a...

And you recommend?

Wow guys don't anybody get heated. What I have is a real Huanyang inverter, not the monkey copy one from Ebay (and I do know the difference).
Specs are;
Model HY01D523B

Input Voltage 220v...

So, you say I must have one rated for 3-4kw? Even for testing? What would I be risking, the VFD or the spindle?

Hi every one, I'm currently running 1.5kw spindle and need a 2.2kw for the larger collet size. Can anybody tell me if it's safe to operate the 2.2kw spindle on a VFD rated for the 1.5kw spindle?,

I've built a number of printers and have played with a few designs. Here's my opinion list about each style;

Mendel Pursa I3

A step above the pursa with all it's threaded rods and adjustments....

Thanks 123CNC. I'll check the firmware tonight. After I saw your post, I uploaded the firmware I used to another working printer and promptly had the same issues. Now I've got 2 deadlined printers....

After building 10 printers for friends and family I've ran into a problem I've not seen before. When I turn on either hot end or bed I see the spike on the ponterface display showing and within a...

Time is on their side buddy. They will stall and put you off, hoping you will give up or the limitations Ebay and Paypal have will run out. I'd be pounding on some door, but that's just me.

If you paid with a visa card via paypal (I'm assuming here), you can ask for paypal to step in. I've had a couple minor issues with sellers who don't seem to understand that in this country the...

Wow! When I was in the Army, we setup sand table models of terrain for preplanning actions (I was a recon and forward fire controller). As basic as those tables were, I know how many man hours went...

I decided to look at the waveform of the voltage out of the driver with my ancient O Scope. For a DC line it has the most trash filled signal I have ever seen. Looks like a AM transmitter signal with...

That seems to have been the problem Gerry. Switching to the unused A drive I'd mounted - just in case - seems to have corrected the overheating issues. I've got it in idle mode and I'll monitor it...

Thanks guys. The stepper is mounted on an aluminum mount. It's wired as bipolar (center tap unused). The current was set to 1.5 amps on the driver when the stepper smoked and locked up. I had found...

Dram - I've heard it said that there are no dumb questions - but I always point out that there are truly a lot of inquisitive idiots. :)

After the day I've had I can appreciate any effort to give...

I'm running a 36v power supply, the stepper driver is a Wantai Dq542ma, the steppers that failed were Minebea Motor 23km-k036-p13v.

As for the voltage that's supplied to the stepper from the...

Hi guys. Today I smoked two steppers on my x axis with very little run time. As soon as I felt the first stepper warming up I started checking for a problem and found nothing amiss. The leadscrew was...

Hi guys. I'm busting my (small) budget buying software for my CNC router. I have Mach 3 for machine control, a couple CAD programs (Corel Draw, Corel Cad, autocad and others) and now I've added Cut2d...

I'm doing the same thing, BUT I'm not sure I'm happy with it. I started out with 425ozin NEMA 23's but they seemed to bog down in a way that indicated that I wasn't getting enough power to the...
