90ZYT-155-12-MCP4-60:1 and JRK 12V12

For 4 motors are necessary 2 sabertooth 2x32 and 2 arduino uno? It's ok also arduino uno clone?

If there isn't too much load (weight) onto the lever (like TL) the jrks should do the job.

yes, yes and yes

....yes but better avoid to smoke jkr....so better sabertooth probably.
Arduino uno clone like this one might be ok?

maybe, maybe not. I would give it a try.

Nah, the JRK is still tripping out on the TL because I am using one of my big 5300RPM motors. I switched my 2DOF motors to 4300RPM motors which are sort of okay with the JRK's but I would like to swap all the motors out for 5300RPM ones with something like a couple of Sabertooth.

In this case two SaberTooths are a lot of money...You can just use a second Syren if you only need to drive one motor - @BlazinH could share more information here
As I already mentioned the Sabertooth (and I assume also the Syrens) are really dead easy to use

I attached the complete datasheet of ZYT90-155-12-mcp4 60:1 in wich is clear specify 40A peak current....I suppose really too much for Jrk 12V12. The file show Gh1466 version (5100 rpm) - my motors are GH1467 version (4000rpm) but this I think not change the current peak of 40A.
....I suppose really too much for Jrk 12V12

Now in my bag I have:

- 4 x ZYT90-155-12-MCP4 60:1 180W 23A nominal - 40A peak

- 2 x ZYT80- -12-MCP4 50:1 150W 15A nominal - ___A peak (less than 30A)

- 4 x JRK 12V12 (2 new unpacked - 2 just assembled and tested)

My options are:

1) Use 2 ZYT90 for pitch/roll - necessary buy buy 1 sabertooth 2x32 + arduino uno - Use 2 ZYT80 (1 for surge

and 1 for TL with 2 Jrk 12V12. Items to buy: 1 sabertooth 2x32+ a arduino uno. Items to sell: 2 Jrk 12v12 and

2 ZYT90

2) Use 4 zyt90 (2 for for pitch/roll, 1 for surge and 1 for TL). Items to buy: 2 sabertooth 2x32 and 2 arduino

uno. Items to sell: 4 Jrk12v12 and 2 ZYT80 motors

Ciao Gigi!

Hi gigi! If I understand well, you can use MCP4 with jrk by reducing power sent to motors, like @Blame73 did.

Hi Mirko. The problem is not mcp4 gearbox but the ZYT90-155-12 motor. This motor have a coninuos current of 23A and a peak current of 40A.... highter than 30A that Jrk can support .

Erwan960 suggest to set in pololu the max current at 30A in pololy utility.
Now I don't really understand wiche is the best solution.

Yes, and what I've said is @Blame73 use well this motor http://www.ebay.it/itm/381920267399 with 23A continuos with JRK... but he must limit the current to avoid damage to JRK.

Come ti dicevo, ho parlato con Blame73 per chiedergli informazioni: lui utilizza dei motori che assorbono 23A continui con le JRK. Non ha problemi di rottura perchè limita la corrente (attraverso l'utility JRK credo, o comunque attraverso SimTool credo che basti abbassare la percentuale dell'effetto)

I will use the same motors on my new sim.
Erwan suggest to limit the current but earobbie say another thing
See the discussion https://www.xsimulator.net/community/threads/diy-2dof-simulator.4793/page-16

No, I just lowered the motors power (duty cycle, acceleration, out of range d.c.) in the jrk utility motor tab to around 300 (600 means 100%)
I tried to limit to 30A or to use 0 (unlimited), no differences.

The problem is when motors need more power for fast changes (like for a fast movement from min position to max position) they could give 'motor driver errors' cause they don't get all the power they need.
