Hi Sam

Not too familiar with the tower foam cutters,but I would have thought that with them being identical towers and each one supports/carrys and guides the hotwire through its paces but at identicl co-ords therefore all axises motors wired in parralell with each other on the three independant axis.

I see in your screen layout that one axis is out of sync is that the way it should be?

I'm thinking if one axis lags behind this would cause a problem?
