Strategie bei Hurco BMC20 refit / Interfacing the Drives to MESA

Not completely sure if you are asking for hardware recommendations,
For the 7i80HD+7i33TA+7i64, you would also need to add a 7i34 in order to be able to connect the 7i64

But a far less expensive route would be a 7i92 + 7i77 and if you need more digital IO maybe a 7i84. That would give you up to 5 axis + spindle (or 6 without spindle) + 16out + 32in just on the 7i77 and 16out + 32in more if you add the7i84 (The 7i84 could connect directly to the 7i77's Smart Serial port. or you could use another Smart Serial card like the 7i64)
If you need to connect more than 1 Smart Serial card to this combo, you would need to add a 7i74 to the other port on the 7i92.

Thanks for your Input,

I will follow your suggestions and go for 7i92 + 7i77 with optional 7i84
Is this setup straight forward enough for a beginner?
Or could it be a better decision to use the same hardware as Tom (he has the same machine) and if he supports me so far? wire the machine identical to rely on his setup as close as possible?

Another question is the PC Hardware i already contacted the Chinese Supplier of the PanelPC and i Could get this J19000 based PC with 64GB SSD and 4GB Ram and dual NIC in 18.5" touch with 1280x1024 for round about 550€ to the door!
Is it expectable that this hardware is good enough?
They claim to support Linux with this hardware?

Another input which came up above in german was to throw the Servo Drivers out because the old ones could be crap... And YES we tested the machine a few days ago and there is a red failure light on... So whats your suggestion throw this servo stuff directly out 1kW Lichuan Servos incl. driver and encoder are around 300€ per axis... Shall I go for it?

I want to have this rebuild done once and properly so it lasts kind of for ever at least next 10 years!

I appreciate your help a lot!
And wanted to thank all of you!

I have an Industrial boxed Panel PC available (2 of them) the are not very high powered but completly waterproof and in a stainless steel case without touchscreen.

Do you think this Intel Atom N270 @ 1.6GHz could be fast enough, it only has 2GB Ram but this could be upgraded.




Thanks for your kind support!

What Andy says is true for RTAI and non-Ethernet interfaces, but If you are using a Ethernet card and Preempt-RT you would probably need more horsepower. The dual core version of the N270 (N330) is just barely able to run a 1 KHz thread reliably on Preempt-RT...

I would suggest nothing slower than a J1800/J1900

So today I took some time and performed the Latency Test and tried some random Stuff while the test was performed (moving files, connecting ethernet, opening and playing youtube videos, moving windows) the outcome seems quite promising to me what do you think?



Please keep in mind I plan to use this hardware with Ethernet based Mesa Stuff and Or Ethercat based Servo-Drives

I have 3 of these units available got them nearly for free...
If they won't be suitable I would try to fit another small Mainboard into the case...

I appreciate your support!
and want to which all of you happy Easter.

HI folks,

I am currently about to decide which Servos I will go for, in generall NEMA51 types will fit pretty good not direct bolt on but easy to adapt.

I made inquirys about Lichuan and Leadshine not Delta because there is no 1kW NEMA51 type which would fit

So I hope you can help me with the decission, I personally see that the +/-10V Interface plus Encoder Feedback seems to be very common BUT some of you use ETHERCAT and I personally think this is a very smart solution only Leadshine is able to provide ETHERCAT as an option for there servo drivers BUT I found nobody using these servo drives through Ethercat any doubts???

I appriciate all your Input a LOT!

Thank You!
