Re: Easy Upgrader not detecting Eurostep Controller.

It turned out that the problem was nothing to do with the cable. This thread suggests that Easy Upgrader won't work with Eurostep controllers and that MintMan should be used instead. http://www.denfordata.com/bb/viewtopic.php?f=41&t=3692 With MintMan's comm port configured as 19200-8-N-1 and a V2.1 ...

Re: Easy Upgrader not detecting Eurostep Controller.

I think I know what might be causing this. The cable has pins 4 and 6 correctly cross wired, but in addition they're linked to pin 1. Pin 1 would normally be Data Carrier Detect (DCD), but Baldor use it for the cable screen, so pins 4 and 6 are probably being pulled permanently low. Unfortunately I ...

Easy Upgrader not detecting Eurostep Controller.

Before spending money on VR Turning software I wanted to make sure that my PC could actually communicate with the Eurostep Controller in my Mirac via an RS232 serial link. The Eurostep Controller is known to be working. I used a cable wired as shown in this thread http://www.denfordata.com/bb/viewto...

Re: VR Turning and serial port.

The control card is I believe a Eurostep and is pictured in this thread:-

viewtopic.php?f=40&t=5620&p=22582&hilit=eurostep#p22582

I have a V2.1 EPROM. Can this be fitted to the Eurostep control card?

Thanks, Max.

VR Turning and serial port.

Is there a version of VR Turning that will work via a serial (RS232) port?

I might be able to justify purchasing a licence for VR Turning, but upgrading the serial card to USB is out of the question.

Thanks, Max.

Re: Spindle speed incorrect.

I've managed to fix it. In the file FLSTEP.OPT is a line "highspindle 5000" this sets the maximum speed that can be selected from the keypad. When this speed is selected the maximum control voltage of 10V is sent to the VFD. The VFD has a parameter o2 which sets the frequency the VFD outputs when it...

Re: Spindle speed incorrect.

I've used the pot on the custom card to set the min speed at 100 RPM, but if I call for the max speed of 3800 RPM only 3000 RPM is achieved.

Is there a pot for max speed or will I have to reprogram the VFD?


Thanks, Max.

Re: Spindle speed incorrect.

Pete. I found a manual for the Combivert VFD online. I can confirm that it's controlled by an analogue voltage which is presented to terminals 17 and 18. This voltage varies depending on the speed selected. Martin. Picture of control card attached. I believe it's a Baldor Eurostep? The only pot fitt...

Spindle speed incorrect.

I have a problem with spindle speeds on my recently acquired Mirac. If I select a spindle speed of say 1000 rpm, the spindle actually rotates at about 800 rpm (it wavers a bit) as indicated by the On Screen Display and an independent test tachometer using a reflective sensor checking the spindle spe...

Re: MIRAC. ERROR 128.

It's an option in the format menu. Delete all the files from the disc with the exception of IO.SYS, MSDOS.SYS and...

Re: MIRAC. ERROR 128.

EPROM is labeled "MINT 3.28 V1.6G B1/S-JD3". I'm beginning to wonder whether the problem is down to the way I'm running the software. Copying all the Mirac or Flstep files to a floppy disc does not make it a bootable system disc. I created an MS-DOS start up disc using a PC running Windows XP. It's ...

I've just discovered the MInt Manager utility. I'll see if I can talk to the Eurocard using that.

No put down intended Pete. I'm sorry if it came across that way. Regarding experience, I have a good theoretical and practical knowledge of electronics. I know how PC's dating from the 1990's are put together. Not so good on software. Alas I had no joy with the Flstep software along with the .go and...

Thanks Martin. I'm amazed that Denford still have info on such an old machine. I'll give the settings and flstep a try. If it doesn't work at least I'll know I'm looking at a hardware problem. Pete.

Re: MIRAC. ERROR 128.

Thanks for your reply. I read through a number of error 128 posts before starting this new thread. The reason two com ports are installed by my .go file is that one was used for a serial printer. This is no longer connected, so I suppose I could edit the .go file to only install the com port for the...

VR Milling 5. Software versions.

I've noticed that the last version of VR Milling 5 to be formally announced in this section is V5.61.

The version available from the download page is V5.66.

Is there a statement available showing the changes in the latest build?

Thanks.
