Check machine values for series, distance, backlash, lead error, etc.
At main screen, press "*", code = "11235", "ENTER", "ENTER"

on switching the machine on to home the axis it goes the normal motions of x,y,z homing but right at the very end the y-axis figure jumps -7349761 after which the machine stalls. This error occurs everytime and as things stand I have no control over the machine after this point.
I anybody has any idea what may be causing this or has previous experience of a similar problem, could you please advise me as to how I should best remedy this situation. Thanks in advance.

tried what you said but once the machine goes through the motions of homing the axis the keys are rendered inoperative ....nothing at all happens when i press them ...even tried pressing the * key at various times but still nothing
getting desperate now
If the keyboard does not work, there are usually two reasons for it.
First is that the mother board looks for a full size keyboard. The half size one is not recognized as good. Thus this test is shut off in CMOS. To check or set CMOS, you need to attach a full size keyboard either at the back of the monitor cabinet or at the mother board.
I have also seen the ni-cad CMOS battery leak and take out the wiring deposited on the mother board. Typically this includes those going to the keyboard plug.

Problems never seem to be far away from me with this machine ..just came back from holiday and cant get it to start up at all ,we switch it on and the screen goes through the process of checking the memory and stuff then it says "waiting for BMDC" as it counts down,normally it kicks into life at about 12 but now passes this point and goes right to zero when at this point the message says "set parameter1 failed" anybody any ideas on what has caused this and how to solve the problem?
If it counts done to zero, the BMDC is not loading. This side of the pond it says no BMDC desktop. i heard your software is different. But, it has one or more of these difficulties. cannot read the mass storage device correctly (hard drive, flash card, etc). Usually this may be a CMOS problem especially after a extended period of being off. I get these calls after a longer than usual weekend. The CMOS batteries that are weak fail. So check your CMOS. You may also have corrupted software. Lastly you have a bad connection to the BMDC. Remove it and clean the edge connector with a soft eraser and reinstall. Be careful to put the ribbon cables back the way they were.

IT probably is the batteries now that i think of it because theres always been slight start up probs if the machines been down for a few days ..can they be replaced? and if so where exactly are they as i havve had both the boards out and cant see anything that resembles a battery
Thanks a lot for your help buddy
If it turns out that it is a weak battry will it eventually work if i keep the machine on all the time perhaps?
There are many mother boards out there. Original ones used a stack of 3 nicad button cells soldered to the board, covered with heat shrink tubing, near where the keyboard plugs in. Later mother boards used lithium coin sized batteries. The half sized mother boards used "Dallas Real Time" chips and later the lithium coin type batteries.
The nicad type I purchase at a local electronics supply store. Unsolder the old and put in the new. I use a temperature controlled soldering iron to not damage the board.
Replacing the nicad requires charging it by leaving the machine on. Lithiums do not recharge. But the CMOS still needs to be corrected in all cases.

george this may seem a stupid question but what do you mean by correcting the cmos?.it might help if you can explain to a real novice what a cmos is
again thanks for your help
Every mother board has parameters maintained by the CMOS battery. These parameters are called CMOS. They tell the mother board what time it is, what day it is, what hard drive it has (set by heads, sectors, cylinders, landing zone, wprecomp. and LBA mode but be aware that these values are specific to your device), type/size of floppy, and many other things.
Most newer mother board CMOS can auto detect a hard drives parameters UNLESS you have a larger hard drive FDISKED at a smaller partition to be compatible with older mother boards. Yes, it can get involved. You need to have a geek friend.

George we cant find anything on this mother board that resembles any of the batteries you described the only thing that seems to be there is called "realtime clock lithium battery" would this be the part that you guess has died? premierpatterns@btinternet.com ..if you could send a message to this address i could reply with pictures
Is there any way to identify the motherboard model?
