REPAIR
There is a repair charge of up to $45 per axis, This is only available for motor drive boards less then 15 months old, and with our discretion, The boards must not have been modified or altered in any way, and must be in repairable condition, 

   Always make sure you have absolutely  identified the problem before installing a new or replacement.

       The four most common human error causes of drive failures are:

WIRING  -  it doesn't take much to make an error when wiring or re-wiring your Drive Board,  it's your responsibility to ensure you understand what your doing, always double check your work, or ask if you don't know, mis-wiring can not only destroy the drive, but can also destroy the PC that it's attached to. Care should be taken when wiring to terminal connections, even a single stray wire crossed into the next terminal, can cause a dead short condition resulting in an instant drive failure, the use of proper wire termination lugs, can prevent this simple mistake, also insure your wiring is tight, and cannot come loose, a single loose wire can damage the circuit board, examine your work closely before applying power to the board.

OVERVOLTAGE - 35 VDC is the absolute maximum the drive board can handle without being permanently damaged, always stay below by using a 24vdc or 12vdc power supply

STATIC ELECTRICITY -  Static charges can be built up in you or by other means, and be discharged in the electronics, causing failure, everyone at some point in time has built some static charge and had a small shock, touching something and discharging, for our drive boards a Static Discharge to it's circuitry, is a sure way kill it, always discharge yourself on a known earth ground, before attempting to handle or even come close to the drive board, Static also really likes to build up in vacuum systems, never vacuum anywhere near electronics, and always take measures to ground your vacuum if your using one for dust collection.  Large amounts of EMI (electro-magnetic-interference)  produced by Tig Welding, Arc welding and Plasma cutting arcs can also cause problems, the EMI coming from this type of equipment, is so strong it can actually harm the circuit, cause missed and unwanted steps,  properly ground and shield all affected areas and yourself  

HEAT - Make sure there is adequate ventilation,  the use of cooling fans are recommended, insure the electronics enclosure is large enough and has adequate holes and fans to allow air to transfer in and out of the enclosure. Over-heating can occur if the drive current is set to higher levels without proper cooling
