General Mach Discussion / Re: THIS IS DEDICATED TO "HOOD"

In the early days of converting my Denford Triac, I had more communications with HOOD than my wife. His prompt replies and on the mark diagnosis were brilliant and solved several problems. He never gave up on me, thanks HOOD. I have already given him a kightHOOD arise Sir Hood.

General Mach Discussion / Jogging keys

« on: April 27, 2010, 03:53:02 PM »

Hi, can you tell me how to asssign the Z axis movements so I can use the keyboard. At present I can jog the  X and Y axis with either the arrox keys on the keyboard or click the mouse on the on screen jog buttons. However the Z only moves with the on screen jog buttons activated by the mouse. Can I assign the page up page down for the Z axis?

OK they are sitill there, I took the wires to the motor from one of the contactors as it was connected to the ATC which I removed, the spindle then started working. I kept a record of the wiring and when I have caught up with the job outstanding will have a go. There are so many wires going in some at 240v I was worried if I used them might do damage. When setting up the stepper drive cards I has a strange 240v supply into one of them which blew it up. Denford were renownwed in the early days for making adaptions and not recording them in their manuals.  Attached a picture of the contactors for your reference, you can see the number of wires going into them, dont need M4 so going on the saying if it working dont mess.

Hi this is just for reference, I noticed I had sent you the latest LYNX manual, I have tried to attach the correct one, Nothing has changed it looks as if you need to attach something to it to get reverse. Hope you got the attachment (for your reference only)

OK Roy at DIYCNC has identified as a 1uf capacitor so might have a go later. Hood I'm going to dump all the denford stuff including an origonal manual. Do you know anyone who might want some bits, Already flogged the toolchange mechanical parts, front panel and 6 off SD2/3 drive cards on ebay. But the rest I'm going to dump. If they pay the postage and they can have it for free.

Hi Hood again you have hit the nail on the head. If you remember I could not get anything out of the LYNX08 board at the start of this thread, so I bypassed a couple of relays that were linked between the breakout board and the LYNX spindle board. I think they were controlled by signals from the ATC as the spindle had to stop in a set position to line up the dogs of the toolchanger and the slots in the tools. It looks as if Denford controlled the spindle with a mixture of the DC drive and AC contactors. I'm going to leave it, as I said I can't think of any reason why I would want an M4. Later on might invest in a new SSD 512C unit from the inverter supermarket which is the replacement for this unit. It has a reversing option but at £110 seems a lot just to tap holes. The LYNX08 aint going to last long, one of the capacitors has blown but does not seem to affect its operation. Cheers for all your help mate

Just checked the manual for the lynx08 drive board, it does have a reverse option and dynamic breaking, what ever that means.

Yep I think it does the old denford programming had an M3 and M4, it also had a tapping subroutine as one of its options. Would it do any harm if I assigned output 2 with the same pins as output 1? that is pins 16 & 17.

Hi Hood I set up the spindle according to the tutorial video troubleshooting, You know I can't get the spindle to reverse. well in the video its shows CW and CCW using the same output. So I set output 1 for both with pin 16 & 17 according to my breakout board instructions. Do you think if I set CCW as output 2 and used pin 16 & 17 again it would work. If it goes in the same direction I tick the dir section. As I said I'm new to electronics so don't like changing things with seeking advice.

Hi Hood  just cut my first job, nameplate for my granson took about 20mins. All fine however I notoced the motors run a bit warm, they aint that hot but when I used to use the denford software they stayed cool. I have an enable option on my stepper and my spindle drive will this cut down the temperature of the motors or am I worrying about nothing.
