Denford Software & Machines

hi! my novaturn lathe not working . somebody help me please . many thanks
-windows7 operation system
-rs 232 cable ( working fine with another denford machine )
-VR 1.53 turning with licence key installed.
i don,t know nothing about the Eprom chip ,but i think maybe this will be the problem,
i try upoad some pictures .
how can i upload any pictures here ?i see many emojies but the picture upload not found it.

-on my Eprom chip - MINT 3.28 marked
v1 6h/S-JD5

-the seven segment show red capital L with flashing dot
- the X axis slide sensor red ( i don,t know that is normall or not? ) thanks again.

As no one else has responded yet I thought I would ask if this is a system you have had running in the past and has now stopped working or if you're trying to get it working for the first time. This thread viewtopic.php?f=54&t=3167 mentions 'L' likely being a issue with loading the mint file so maybe a comms issue. To attach images use the facilities at the bottom of the posting page.

thank you David .
i try first time .but now start change the control board from smartstep to nextmove st ,
the nextmove st controll board come from microruter .
the last picture show the wiring diagram .
- i was try change the eprom chip to v2,1 but nothing .
- i try select another machine parameters "novaturn NS " nothing
many thank David .

Worth checking first for any deposits around the battery on the Nextmove board as they are prone to leak electrolyte after many years which may effect the comms. If there are deposits they need to be removed with distilled or deionised water and dried. In many of the Denford installations the battery isn't required, I can't say about yours but the answer may be elsewhere on the BB. Make sure you're discharged and ideally use appropriate handling of likely static sensitive devices.

I would try with the EPROM it came with. Some good information here for the Nextmove ST http://www.abbmotion.com/support/suppor ... _01-10.pdf about communication with the board and fault finding and the earlier board https://www.baldor.com/Shared/manuals/1251-396.pdf , at least the RS232 connections are the same although it indicates the default comms parameters differs with the Nextmove using a higher baud rate.

hi! DAVID .
my next step control board not battery fitted .

I found one wiring diagram nova turn den step to next step.
but me need smart step to next step wiring diagram .

your next step 80 pages documents very help full and thank you very much.

Where are you located?

In order to run VR CNC Turning you will need a VR Eprom version 2.0 or 2.1.

Also I don`t think the RS232 lead you have shown in one of the pictures is correct.

hi! Martin
I live in DEWSBURY . any chance that you inspect my machine (Denford novaturn ) i can send to you more details if need .

me have Baldor NEXT STEP control board from Denford router and need swap or just fixing up the current smart step control board to running . me have VR turning software . many thanks

You have a DOS EPROM fitted so cannot Run VR Turning.

Eprom is V1.6h/s

hi! first thank you .
so me need change the Eprom chip ? where can i buy one ?and what the pats number please . thanks.

I try change the E prom chip but nothing .

It is only the SmartStep/DenStep top board that needs the VR EPROM

If you put the original EPROM in the NextStep board are you able to detect the control using Denford Easy Upgrader?

Have you installed the Baldor USB Driver?

Have you selected Novaturn NS?

Hi! I try step be step . Working !!! I upload some pixtures because simething not perfect . All axis go to home and spindle spinning . Today try the tutor . Ease see the pictures . Many big thanks .

If you right mouse click on the orange banner in EasyUpgrader when you are connected then go to Advanced, (password is "dave") you can change the machine type. You may need to set it to Unknown.

thank you ! all working now .
the next step that how programming
big thanks !
