Hi guys I dont know if anyone here can help me but here goes.. The problem I am having is for some reason when i switch on my machine and run the software program the drives just go nuts running up and down the different axis like it's got a mind of its own. It dosent do it all the time only sometimes but more times than not, it runs on three servo drives with encoders on the top of the drives. I have used the machine lots of time with no problems but it's doing my head in I have checked for looses wires but cant find any.
Thanks in advance.

Well if all 3 axis are doing it then i will be a problem with whats supplying the signal. so chances are its your board.. what board are you running btw also what software?

Hi the software is amtechs gnc software as for the board im not sure, when i open the controller box there are three mini maestro drive boards and the controller is connected by two scsi cables.
By the way sorry for the delay in replying.
Also i have replaced the wiring from the encoders and its still doing it.
Thanks

You talk of scsi cables, is this what connects you controller to the PC? or are you using conventional printer cable to the parallel port? if you are using the later something else may be sharing the interrupt for that port.
If the nagging gets really bad......Get a bigger shed:naughty:

Hi the connections are two 37 way scsi connectors which have their own i/O cards in the computer the machine runs fine sometimes and others just goes nuts im thinking of changing the whole controll box if i cant get it sorted, is their any way of checking the drives and encoders before making any drastic decisions.
Thanks
