Thread: The illusive Boxford 260vmc
Ok fitted BOB today, all axis move in one direction only!!! but sound rough and move very slowly so a bit of sherlock is required (par for the course, how much is simple nowadays)....

Check for voltage at Dir +&- also pulse? on BOB inputs
LOL how stupid can one get....derrrrr forgot to connect GND on BOB. All Axis now work both step and direction!!! im off to play for a while and tune the motors :)Always bear in mind that your own resolution to succeed is more important than any other - Abe Lincoln
Ok im going mad,, will someone take a look at these two items and tell me how they interface and how they connect to the bob please ive tried for two hours and when it gets to that my experience tell me im doing something wrong...
there are only three connections to the lenze 534 to the speed interface and although it only shows 1 connection to the breakout board there is also an rtn connection.....:confused:
pins 7,8,9 are for the speed control using a 10klin pot or circuit below

0v on speed controller TB2 to pin 7 on Lenze
+ve on speed controller TB2 not connected
STEP on speedcontroller TB1 to BOB Output (typically pin 8)
RTN on speedcontroller TB1 to BOB Ground associated with the chosen output
Do NOT share the grounds... they may not be the same ground level...
Thanks irving, did you know what the rtn connection on the speed control to bob is..
RTN = return
see my post above... connected to BOB ground alongside pin 8
