You are welcome ... :)

And I wonder about the result then ...

Actually I've a friend, who has a new Siyl X3 also with rotary axis...
we plan to try the rot axis soon ...

Here it is one of...

Hi Wade,

just download and try the 'M_MACH3R.ppr' from ***********

http://tech.groups.yahoo.com/group/dolphincadcam/files/Post%20Processor%20Files/Mach3/

it is a Mach3 post processor with...

How about current limit? ...

Hi Mick,

regarding my experience, it is more important the proper current limit...

regards,

Jozsi

Great job Henrik, congratulation! :)
And thanks for the super documentation and photos ...

Hi Mick,

as far as I remember I had also some problem using HEDS standard encoder with the SN75115N differential encoder, so I simple took it out an I put two wire 'jumper' into the Ic shocket for...

Hi John,

on the picture I can see the original UHU board (not the HP UHU)...
It is really more stable than Embedded, but I had reseting problems with big motors ( 136V 15 Amp 1kW)...
The real...

Might happen, but it is better to get answer first...
In winter for my second order I just sent the "beer money" and then the order... Uli was surprised..:) and took about two weeks to arrive to...

This time for splindle only... (Standard UHU for up to 200W, for X and Y on lathe.)

Hi, thanks for the video, watching the longer one I can recognise an oscillation at stop ... increase the H value ! The basic settings are for smaller motors ... ;)
Jozsi

just make an account on http://www.youtube.com/ , upload the videos and post here the links ... :)
We are waiting badly for new movies....
Jozsi

Different motor needs different setup, and as for start, the Uli's initial setup values are quite good... I needed to play mostly with P and H, P in range 600 - 1600 and H in range 8000 - 20000. The...

That sounds very interesting ...

Hi Lucien,

to make a screw is not a problem, with Mach3, I did already some with other machine... The big challange was the big spindle motor, but HP UHU solved the problem... :) Next time when...

Jumper P3 you can find on the board, same pdf, page 8 , above U9, R40 than P3... It is useful for oscilloscope and multimeter...

Hi John,

"C32 capacitor (1 uF 250 volts Metalized Film) has
to be soldered across C31 terminals on the copper
side of the board.
Be carefull not to interfere with the heat-sink."

Hi mick22,

just drop an email to [email protected] or direct to Irfan, (contactirfu above) . The reply is coming soon, there is no need to worry... ;)

Hi vroemm,

I had troubles with the original UHU board, it was too sensible to noise that is generating via high voltage and current... I could run the 1kW motor only with very slow acceleration...

HP UHU - MINITURN spindle RPM, Current test, at 1000, 2000 and 3000 rpm, forward and backward turn. HP UHU is set to higher than 11A, Vref=0.22V ...

Here you are... ;)

On the other hand my HP UHU kit arrived from the US in 3 days (!) as industrial sample no problem... ( no commercial value... )

Have a look at Kreutz's post #1861 above... and http://gsst.wikispaces.com/UHUget ...

Hi Henrik,

how many voltage you set on Vref ?

I left R21 6k8 unchanged. While 10k was parallel the asymmetric torque come again..-

Hello, Everybody.

Some feedback and conclusion regarding HP UHU and the Lathe...

On Friday and Monday I could continue my tests and even challenging the board, nothing blown up...
The power...

Hi rokag3,

What kind of NC program do you use for lathe? Do you use 1:1 spindle pulley ratio only?

I use Mach3, but it does not expect spindle index signal from the spindle motor controller...

Well, the board will be built into the lathe housing so I leave it as it is...

Hi Henrik,

yes, but I turned off the fast limit track with pulling out R41 leg from U9 13pin and connected to gnd. The slow limit track seems work, and the led is turning on. I've just read...

Hi Kreutz,

I've just made a test for slow current limit and Led. I turned off the fast current limit, pulling out the right side foot of R41 and soldered to gnd with a wire. Replaced R32 with 470...

Hi Todor,

I had it tested only short period of time and open air not in a box. The dump activates itself only on higher rpm... While the 3 * 50W dumpresistors become warm a bit ( 30 - 35 C) the...

Hi John,

I built two Embeddedtronics UHU board and they work well with my small servo motors ( Elektrocraft E240) I like them, they are Gecko size, small. I had no torque difference problem in the...
