Higher end Chinese controllers?

[JAZZCNC]

So your assuming it can square the gantry individually or you are doing it.? . . .. You do know what they say about assumption.!!!

If you are using 3 axis controller how are you running your machine which as 4 motors.? Are you using the servo drive slave option, meaning the slave servo drive mirrors the master. If not then surely your not connecting two drives to one Motor output.?

I have just taken delivery of a new batch of these controllers but instead of being called 1.1 this model is called 2.1

Personally i think they are the same just that these have a neater and cleaner button layout and all in English.
Manual is the same manual, I think but again better English although it shows some of the V1.1 screen shots inside.

Doing some testing over the next two weeks, eye operation not withstanding then got 15 machines to convert down in Oxford 3rd week of November.]

Without this stand alone controller I would not have got the job.

Is this the NEW990TD-b controller.

No it's the next upgrade to the dsv1.1 controller.

Surely i am connecting 2 servo motors to one output without any problem. Reality is different that what we think is good or no good. Works perfectly. And if works perfectly at my speeds, for the normal DIY machine will be a winner

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.!

Yep my DSP lasted under a year, warranty, yeah right. Now running CS-Labs thanks to Dean.
