The reality is that over time the tiny difference in timing issues will show up and with no way of squaring the gantry indepedantly, other than running into hard stops, the machine will slowly twist it's self up. Not good arrangment and not something I'd do or encorage.

The problem and concern I have with these controllers is that they are not much more than DSP controllers which are fitted to many chinese machines.
It's well known that these are trouble and I've helped countless people who have bought chinese machines replace DSP's after little just 6mnths because they have failed or start acting strange.
When they start giving trouble there is very little can be done and they are throw away.!!!

I never call or praise any hardware untill I've fully test my self so I'm not calling them or saying rubbish. But I will be trying one these for my self and after Thrashing it for several months then I'll see if it's Winner.!
