Hi,

I notice there's quite radial play of the SX3 spindle. I hold the spindle lower end (the tool holder) with one hand and hold the top end with another. One hand pushes, one hand pulls, then...

Hi, there,

I got a Renishaw TP2 5W probe from eBay. However, I found the styler tip is not at the centre. I mount it on my milling machine and rotate the spindle. The runout is about 1mm peak to...

I think there was a discussion regarding RTAI vs Xenomai vs rt patch to the kernel. Is EMC considering other two options?

It would be nice if there is a Mach to EMC converter, or just add an import function to the stepconf.

I think besides the pinout of the steppers, you also need to write down some other parameters...

Since the next LTS Ubuntu is scheduled April this year, is there any plan to port EMC2 to it?

FYI, http://cdimage.ubuntu.com/releases/hardy/alpha-4/

To mount Windows partition (NTFS) under linux, it is better to use ntfs-3g. Ubuntu 6.06 should support it.

If you want to run Windows programme under linux. You can either try WINE or install a...

hi guys, wouldn't the higher voltage increase the EMI and heat up the motor due to the higher eddy current?

Please feel no offense, I'm just a beginner trying to find out the truth. Although some special work, like the lapping, sounds exciting, does it really improve the accuracy? which can be offset by...

I also wondered if the engine oil can be used? like 5W30? too thin maybe?

Sam, thanks for your input.

I hate to boot up a computer for a simple job, like drilling a few holes, split block, etc. So I want to be able to operate the mill semi-auto without the PC.

So...

Hi,

I'm thinking to use EMC for my next project. However, I do not have any experience with it.

The idea is to have an MPG connected to an exernal simple controller. This controller can...

I'm in UK as well, and I found the cheapest slideway oil so far is this CASTROL MAGNA BD68 from

My SX3 had the same problem before. I don't know what exactly you mean by "main board". My problem was solved actually by replacing the spindle motor driver board, which takes the speed and direction...

If you use unipolar, there will be 5 wires; bipolar 4 wires; and if you use 3-phase stepper, you only need 3 wires. ;-)

Hi, thanks for your reply. I had a mis-concept that the micro-stepping could save a stepper from resonance, but I still got the stepper stalled with a micro-stepping driver. Now I shall try this...

I've never done this myself. But I don't think connecting two steppers into one driver sounds a good idea, as the stepper coil may vary up to 20%. Connecting two controller with the same parallel...

Hi,

Thanks SJH for bringing the light onto this dampener issue.

Also, Fixittt, thanks for your very impressive video. The damper there looks rather simple. Is it just a bar with two screws and...

Hi,

Maybe the battle for this reverse current problem has been finished already. I just wondered if it would be possible to have the MCU detecting such higher voltage and drive the low size...

Hugh is a nice man. I bought my machine and a couple of other tools from him. His service is the top class. You don't need to worry any about the after sale support.

Hi, John,

Great work with your scraping. Please feel no offense, I just wonder how much the improvement you can get with the super 0.002mm flatness, simply because if it is an effective way to...

thanks for your reply. Since this is my first machine, I just don't know how much I shall expect. Is there something called "zero backlash ball screw"?

hi, I measured 0.017mm backlash on the X axis. Is this normal or I need to adjust something to make it less. thanks

FYI, this problem has been sovled by replacing the PSU.

As I mentioned before, the Syil UK support sent me a replacement very quick. However, this new spindle driver board does not look the same as the one in my machine, and in fact, they are not...

Hi,

I received my replacement spindle driver PCB today. It looks different from the one currently install in my SX3. Just curious which one is the latest one? actually, I don't mind as long as it...

The PSU has gone. I'm getting replacement on Tuesday. Hugh is really helpful. Actually, I need the SX3 up and running these days otherwise my project would be a lot delayed.

Hi,

Don't laugh at me. Just my luck couldn't be worse. Before I sort our the spindle drive problem, I got a dead stepper power supply, I think.

Firstly, what ever I tried the stepper simply...

what's the part number of this chip? thx

if you turn the spindle over the "dead zone" manually, it runs, but you can hear the jitter noise.

I've recorded a video showing the problems, and it is at http://www.deligeng.f2s.com/sx3.avi

If you work for a company in western country, and they send you back to China for business, they would pay you extra for living there. So whether you earn less or not is still a question. However,...
