Stepper Driver Fault

[john swift]

Was the machine simply switched off and left unused or was move into storage ?

If its been stored in cold damp conditions
check the wiring for damage and connectors and Z axis stepper motor for corrosion


what's the stepper driver part number ?

first I would search for the stepper driver data to see what the fault LED could be indicating
( motor stall , over temperature , internal driver fault ? )

once your sure the wiring is OK
I would try connecting the Z axis motor to the spare driver

Sorted now thx. Simple job to swap wiring over to the 4th axis driver but required a small child contortionist to get access back of the machine :-)

AFAIK the stepper driver is proprietry Syil, attached is Syils PDF& if I cannot source one do you know of any options?CNC_stepper_driver.pdf

I have three of them doing nothing but sitting in a drawer - I live in Cropwell Bishop, PM me if you want one or all of them. BTW they are Tonman drivers and obsolete.

Oooh, yes please. Are they off a Syil SX3 ???

I'm only 20mls away so I could pick them up anytime. How £much do you want?
