Dumb Reverse

[Clive S]

My motors run smoothly but only in one direction

Can you check the voltage on the direction pin on the drive as it should change from around 5V to 0V when you jog back and forward

Thank you for your replies. I have spent a week on and off checking the wiring to the Longs info. Checked every bit of wiring for continuity. Yes I have 5v to 0v drop as suggested. I have noticed this morning that the normal 2/3 4/5 6/7 pin out is not lighting the Z and X diode on the BOB when signaling from Mach. These axis are wired to A and Aux. Stupid of me not to notice that before. Never take things for granted. Will be checking the RS232 pin signals later. At the moment whatever pins I enable in config I cannot activate Z and X on the BOB. So probably got a duff BOB here.
