Best diseq motor?

[arkanoid9]

Hi everyone!
Can you help me to find and buy the best diseq motor ? Any suggestion?
Thx!

 

[butchyboy]

not easy got these days,but if you can get one make sure its got metal cogs.as the plastic cogs wear after a short few yrs depending on how much you wave your wand.

 

[samir mokhtari]

As butchy told you,
it is better not to use a heavy Dish
I suggest this to you, its high quality, if you have it available

 

[arkanoid9]

Thx guys! Can you suggest me a web provider? In PM if is it a problem in public chat

Sorry if this is not the correct section and for my English, but I wanted to ask why this motor stops at east 62 and west 40.5.
I reset the limits and reset the motor from its button but the motor does not go over
many thanks

Resetting on your receiver? I recall looking at a manual for a motor I had and there were mechanical limiters on the motor itself that could be set.

Welcome to the forum, @pluto60 !

Many USALS-programs do not support USALS commands going further than about 60 or 65 degrees from zero, if I am informed correctly.

Do you encounter your problems while using USALS commands? Or (also) with "manual" MoveLeft or MoveRight commands, or GotoPosXx commands?

If only with USALS commands, you can use StorePosXX and GotoPosXx commands for satellites further away from zero.

I'd check this first, before looking into other limit issues.

thanks for the response
Unfortunately, I have problems with both USALS commands, the manual MoveLeft or MoveRight commands, and the GotoPosXx commands.
any other suggestions?
tks

Had me confused for a minute. Am I correct or not that a diseqc motor and usals are different animals. I have heard that usals motors can also use the diseqc protocol.
But when somebody says diseqc. I immediately think of a vbox type controller and linear actuator on a polar mount.

OK, clear.

Where does the motor go when you give your command GotoZero (or GotoReference)? Does it go to exactly zero?
(Are you exactly halfway between 62E and 40W?)

How exactly did you "reset" the limits? With the general Motor Reset, on the motor itself?

I've read that setting motor limits just puts the limit positions in the motor, but that to implement them you have to use the enable/disable limits commands. Have you checked that?

What brand of motor do you have? A SG2100 Moteck (and clones) have settable physical limits inside.

Diseqc 1.2 is a set of motor commands, for both H-H motors and Vbox positioners.

USALS is a receiver "program", that uses the diseqc 1.2 command GotoX (X being a certain angle away from Zero/Apex position).
These USALS calculations don't work for actuator setups, as an angular outcome is given, and the actuator has linear movement. For a linear actuator, extra calculations are necessary (Google for instance: "USALS for buds". I have a functioning calculator for it nowadays, but never finished my draft article about it with the formulas.).

Diseqc 1.0 and 1.1 are a set of commands for switches.

thanks again
technomate motor tm-2300m3
confirmed that the motor when you give the GotoZero (or GotoReference) command go exactly to zero
i reset the limits with the general Motor Reset, on the motor itself.
for the 'last question I verified, the limits are disabling commands from the receiver
tks rgds

 

[a33]

So in that case I think it might be the hardware limits, then. As @saturn9 mentioned.

The tm2300 looks like the SG2100. So I'd think it might be a SG2100 clone. (I'm not 100% sure, though. Maybe other members know?).

For the procedure of hardware limit changing on such a motor, find a Moteck SG2100 manual on the internet.
Alas, the motor tube must be removed to reach the setting screws.

I myself have no experience with the TM2300 though, or with changing hard-limit settings.

I hope this is the correct "diagnosis".

Oh no biggie. As mentioned, when the OP asked for the best "diseqc" motor, my immediate response would have been Von Weise or Venture.
Good thing I read before replying, huh?!
I understand usals and diseqc. And have read both manuals.
Unless a calculator could be built that takes actuator arm geometry into the mix. I would have to state that no linear actuator mounted to a big dish will have X degrees travel in the arc per shaft revolution (or inch, cm extension/retraction).
From practical and everyday experience. 100% of my satellite location predictions are from interpolation.
So let's say for where I live. 131W-127W is 120 encoder pulses. And 127W-125W is 132 pulses (or "counts" on the dish mover display).
As you get higher up in the arc the two-degree per satellite encoder pulses diminish to 90. Then when the dish gets over zenith and aims more towards you folks.
Calculations take a different turn. It's really simply impossible to think that every two-degree spaced satellite across the entire arc is going to show an even X encoder counts on the dish mover control display. And blindscan is very important to snag a transponder signal after what you think may be the target location. Which happens.
So a spreadsheet or simple "cheat sheet" in a ring binder with simple math calculations helps predict where a satellite should be.
Now a diseqc 1.2 controller on a horizon-horizon mount that drives the dish directly from the polar angle pivot should give easy counts-per-degree calculations.
Would that be the same for a Stab type usals dish mover in go-to mode??

Of course I took all that into account, and my calculator calculates exact. Just 5 input data necessary, from the actuator triangle setup (geometry, and apex position), to calculate exact actuator length out of the USALS angle, for every satellite that you want.
The only inaccuracies that arise are due to arriving from left/right at the target satellite position, and/or "play" in the axes/moving parts. So with a bigger dish, I'd always finetune a satellite position, and use a StorePosNn command.

So your thoughts and considerations are long behind me. In fact, they were already when I posted in "USALS for buds".

Hi guys!

I’m picking up this discussion again because I ended up buying the satellite motor that @barney115 recommended, but I was just curious about one thing: does anyone know if it has metal gears or plastic/nylon ones?

Technomate 2300 M3

 

[barney115]

plastic/nylon gears .
Technomate 2600 Disecq Motor has the metal gears but since Technomate stopped supply and duly went Bust it is near impossible to find .
But it is a bit irrelevant really because the Technomate 2300 still gets the job done and will last every bit as long IMHO .
Good luck with the Motor : )

Thanks for the clarification @barney115 !! I was doing a bit of research and it seems that nowadays it's almost impossible to find a new motor with metal gears. All the motors currently being sold have plastic/nylon gears and are made in Asia... To get one with metal gears, you have to be lucky enough to find a second-hand model – and one that isn’t half-destroyed or rusted!
