Z axis error woes

[HankMcSpank]

Thanks guys....would you believe that since my last "solved" post - my problems (missing steps) moved to my Y axis!!

Basically, to solve the former Z axis problems I put in place a chinese TB6560 board...it transpires the 6 way DIP switch (ie the one that sets the current, decay & micro-stepping) for the Y axis was faulty & therefore some of the individual DIP contacts weren't making properly - the outcome being my Y axis was actually only running at 25% current...which made my Y Axis lose steps, which wasted a lot of my jobs (not to mention a couple of days lost time!) ...the solution was to hard wire (with little strips of wire) across the contacts on the base of the DIP switch!

Should anyone be misfortunate enough to hit a similar 'missing steps' problem with a TB6560 board ...if you've the same issue as me it's actually easy to diganose (in hindsight!), the swishing sound made by your stepper changes if your press down on the overall DIP switch! (the switch itself is a nasty bit of manafacturing....I can see a lot of these giving problems)

An unbelievable bad run of luck - & speaks volumes for the importance of using good stepper drivers - that's two consecutive boards that have bit me in the arse in short order!
