Thanks very much for the info Martin, very much appreciated

Martin,

Nothing on the back but there is a label inside 'North East Electronics' Serial Number= 014 and Date = 8/88. The table has the number 451 stamped on the front right hand under the cover that hides the X limit switch.

Kind Regards,
Steve

Hello Martin thanks for your reply. I am measuring the inside of the R8 spindle with a DTI. Not sure what the serial number is... I am not at the machine at the moment but from memory I think I noticed a number on the table would this be it? The machine is circa 1988 if that helps. Thanks Again Steve

Hello All,

I measure the runout of my Starmill R8 Spindle with a DTI and am seeing about 0.015mm of runout.
What was the factory tolerance for this spindle from new?
Is this runnout acceptable (how longs a piece of string)?

Kind Regards,
Steve

Hello All, I mistakenly thought the LCB3 was using unipolar but on closer inspection it is indeed using bipolar. I didn't notice the motor four wire connections (red,orange,black,yellow) at the top of the LCB3 card for the X and Y axis's. I have also since noticed the stepper driver heat-sink locate...

Found the card Parker Digiplan sd2

Thanks for the link! It has helped with regards to main motor out pinout but unfortunately it doesn't mention anything about the step/dir pinouts which I believe are delivered through the connector X11!? It appears this is an older version than the mill I have as it only mentions the number keypad w...

Am I correct in assuming that the PNC3 Starturn steppers are Unipolar (8-lead) ULN2803A driven where as the Starmill SMCU are Biplolar (L297)? If so what was the reason(s) for Denford to go the unipolar route rather than bipolar on the Starturn? I was under the impression that Bipolar is more desira...

Hello All, Does anyone know of any circuit pinouts for the SMUC Driver connections? This is on an old starmill it has 3 X L297 based Parker Digiplan Drivers that connect to a mother board that has screw terminals for motor connection and an IDC connector for step dir. If anyone could let me know the...

Thanks your reply Admin. It makes sense ofsetting from the chuck as you sugest I will give this ago. I followed the tool setting intructions found in the Denford documentation which states to use the end and side of the billet to set offsets. I have attached an OCR scanned pdf of the procedure in ca...

Hello All, Is the [BILLET X Z used for Fanuc simulation only or does it also have an effect on live turning? When using ATC do the tool offsets only need to be entered once? For example if I have a different length and widths of stock will the system calculate the end of stock and centre line zero o...

Hello Everyone! Does anyone know if it should be possible to use the standard PC keyboard to enter text? For example when I hit F3 to load file I am unable to enter any qwerty characters. I can move the machine axis using alt-j etc but am unable to enter text. Below is the info on the .go file. IBM....

Ok I've found the answer....

The gcode output from the cam programme issued a G50 X0 Y0 which home's the datum to the last moved point.

G0 X0 Z0 (moves to end of billet centre line)
G0 X40 Z10 ( move to new position )
G50 X0 Z0 (Sets datum of last moved position to X0 Y0)

Cheers

Hello,

How does one set the workpiece datum point x0 y0 to be at the end and at the center line of the Billet on Starturn FanucL (training) program.
X0,Y0 is currently referenced from the machine datum top left on simulation.

Skipper_steam... So sorry for the delay in replying to your question... like two years late! But have only just this moment seen this reply while revisiting qdenford.kbd stuff. You have probably solved the questions you posted by now ;-) but I stick this down just in case anyone else may find it use...

Thanks for your reply skipper_steam! I will give the M code a try later today. I did try the M code methord ie 3 and 4 but I used the char 'M' and not '-' when entering the M-code ( I onder why) :wink: As far as everything else is concerned I can set the spindle speed etc as you sugessted. BTW Skipp...

Hello All,

I have read the attached key mapping doc but am having trouble with starting the spindle on my Starturn.

Does anyone know what the qwerty key mapping is please?

Thanks,
SRG

After all that I just found the info I was looking for

Here's a link:

The ALT key is used to send command to the controller.

ALT J = Jog etc .....

Well I got this here as a reminder now

Hello All, I am trying to replace the desktop tutor keyboard for a PC qwerty keyboard. My current setup go like this : Starturn Lathe with SMU controller, Desktop Tutor keyboard (fixed membrane type) pluged into two parallel ports on my PC. I can datum and Jog etc when using the desktop tutor keyboa...

Some quick and dirty pictures Of my Starmill upgrade. (It's still a work in progress) Rapids are running at 1800mm per minute which is limited by the number of step / dir pulses that can be sent via the para port. System = EMC2 running under Ubuntu Linux with RTAI Kernel (Realltime Kernel) It's all ...
