What price do you charge for the kits? Do you sell the PCB's by themselves?

Thanks,
Bob

hello
in reguards to mr changs lost controllers.
i have e_mailed him and another fellow and told him i intend to send him 3 more controllers at my cost. this will be done when i have the new controllers available. it is my loss, but thats the fair and right thing to do.
i don't make a living in selling electronic stuff, i do it on the side, i have to focus on my regular job first as it keeps a roof over my head.
i just try to be fair and am doing this as a pass time / hobby, but it is almost like work. :-)

How many $ did you send Uli for the 4 controllers and did you use pay pal or what???

Thx mike

I have some Globe Motors [hollow shaft] that came out of StorageTek tape transports the appear to be brushless [ three power leads] and have shaft encoders by RENCO
The Globe # is 569A124
The STK# is 1565028-01
The sticker on the Renco is D/C 9910 & P/N 77980-035
also has 2 10 wire ribbon cables to a plug ...
Does anybody have any info on these...

The motors are unusable. The UHU controller only works with brushed dc motors.
Encoders may be useable depending on line count. The UHU requires TTL encoders (5v square wave quadrature signal), ideally between 100cpr and 500cpr but counts up 1000 are still usable. Above 1000 you need a step multiplier (built in in the UHU)

try a jrkerr controller,they sell 3 phase controlers, since this is not do it your self ,its do it by uhu controller,dont mind if i smile

DIY = Do It Yourself
Open Source = All design aspects are open for others to improve on or add to.

As for the button missing... Not sure what to tell you there. Maybe try a different web browser?

thanks for the head;s up fifty ohm, i was needing to see if i was the only one with a need (not the use of need 2 times) for conformation,i will be building a 5 axis machine ,the software will be cncturbo(dos) servos will be used,and i will be using a pic chip since i cannot find any proper programming (high level that is) for the tiny chip..source code and such will be posted,smile because i cannot print smillies

[MrWild]

I like to solder and build things. I've played and made some circuit boards and "most" have worked. After looking at the price of a kit versus completely built from Smarbaga, I decided that the $20 for each board is a bargain. Why? Well, Smarbaga has built many of these boards now. If a problem arises, he has the parts on hand to swap them out with new ones without a waiting period. Maybe the BEST reason for the $20 is that he checks the boards thoroughly and scope checks them to make sure the transistors are clicking properly without doing a shot through and everything is functioning as it should. As I don't have a scope and have lost a lot of dexterity due to an ongoing disability, I've gone with the ready built boards.

These will be going on a Crusader M conversion. Once I figure it all out, I'll sell off the Crusader M (not yet so don't contact me) and hopefully have a faster/better control. Has to be a better option than Anilams 3000 Controller upgrade for the crusader M. $7,500 isn't an option for this poor boy.

Is here a way to use motors with brake? Or for UHU controller it is useless option?
Oscar

[ejkoeze]

There is a way to use the enable signal for the H-bridge as a release for the brakes. You'll have to do some hacking with the board but it is possible.

Of course the brakes cannot be used for dynamic braking, just to keep things steady when the controllers are switched off (by emergency stop or regular switch off).

Erik Jan

[ulihuber]

Oscar,

a signal for releasing the brake needs to be generated with the knowledge of the actual trajectory and next action and has come from the CNC controller. If it was generated by the servo board, it would open and close the breake for every single step..

Best regards
Uli

Mr Wild or sombody

Please elaborate on the 20$ option

It's the difference between the DIY board and the board that is complete done and tested.

[smarbaga]

in reguards to trajectory:
i don't understand how a trajectory can be considered if the input or movement signal is a step pulse.
to have a trajectory one needs a start and destination.
also (de)acceleration, torque and a pid loop etc..
how can these conditions be implimented if there is only a single step pulse input.
i can understand if the controller saved a bunch of steps then acted on them as a groop.
but if you had several controllers, say x & y making a circle the 2 axis would have to be sinchronized in some way. ( tied together electronically ).
can anyone explain how these setting can or are be implimented with a step/direction input

You are right, the trajectory, acceleration, deceleration, etc. is calculated by the program on the PC (e.g. Mach3). Uli is also right, there is nothing we could do from the motor driver board to effectively control the brake, it has to be done from the PC program by using one of the available outputs.

you seem to be a very intellegent fellow.
your replies and sugestions are always clear and informative
thank you very much.

My drive does that and works very well from step/dir source. It works correctly even when destination changes spontaneously during move. However drive should have higher accel/velocity limits than PC software to avoid lagging motion.

LOL. Sorry. Not a controller for just $20. Smarbaga sells both kits and completed boards. The kits are a good deal at $90. But for just $20 more ($110 for a complete board), he will populate, solder, and test to perfection the kit so you have a working board and no worries if you don't have a scope or extra parts should a problem arise during testing. Hence, the $20 option.

Smarbaga, u mentioned earlier that you would lend a controller board to Kreutz..........seems U forgot.......Kreutz has his motor ready...........can u lend him a board now...........

i am testing my converted mill with my SMD UHU version, the controller seems to work ok but i have a problem:

there are small acumulated position error when large programs are running, it seems than some noise are afecting step-direcction lines or A-B encoder lines.

somebody have found this problem?
