Aluminium Framed Router

[lucan07]

I have not seen Tweakie post but I am pretty sure that using double opto's won't make any difference to an axis refusing to go in one direction or the other. I would check the cables for loose connections.

post in question attached with reply had seen this mentioned elsewhere all other cables checked have replaced Bob alone and problem is now solved, in short if not problem on occasions why did tweakie come up with response straight away without opto bob or drivers mentioned, why did non opto bob solve problem?

However fixed problem of slipping pulleys before it occured, a bit of testing/tuning first cuts a few slats of 25mm mdf which I have decided to use for first sacrificial bed, had a selection of 2020 off cuts laying around from printer builds etc so using these for clamping t-slots gives me 5mm to skim as needed. Using 6mm Router bit 1st DOC 3mm 2nd 6mm 3rd 12mm MDF using 12000rpm and 1500mm pm feed no problems with cuts. I have used a BOB I was given I think its a cheap chinese import and I appear to be having occasional problems, axis will refuse to operate in one direction, jogging a different axis then frees the original axis to move as required so another BOB on its way, double checking wiring next on to do list, all wiring is CY shielded cable currently all mounted in small pc tower case whilst waiting for cabinet to arrive so may just be everything to close for comfort. VFD is mounted well away from everthing else.
