Tronic's AMC motor motion-controller with pwm/servo output

wow super tronigr :clap:

do I have to change my amc 5.1 Controller something? or only atmega

OMG,
I`m thrilled and scared at the same time 8)

I was about to start printing the boards layout and saw Thanos`s post.
I must repeat Interview`s question: Does new AMC means new board or not?

I`m sure that this will be another peace of art from Thanos, but I can`t find 644 locally and already bought all the parts for AMC 1.5

Yes, but ATmega644 is the one that has all the functions we need for simulation and interfacing.

Its true. But that will be no problem. Since the economy here in greece going down, soon I'll be left with no job too... So I need to prepare for the worst. I decided to start a small production of complete kits or ready assembled boards of AMC + DSMHB. It will contain pre-programmed chips (Atmega644 + 2x Attiny45) and everything that a beginner will need to get started in no time. I'll try to keep the price tag low, and the shipping will be worldwide.

I do not see it as a business but as a hand of help for all these that have no access to certain electronic parts or knowledge to put them together. So don't get me wrong... For the brave in heart there is still the good-old AMC1.5 available!

No, it will not be compatible with the existing AMC1.5 board. Its a complete new board redesigned with modern parts and functions. It will be only USB and the inputs will include optical encoder hardware and configuration menu on the LCD with rotary encoder... The outputs will include the hardware for 0-11v signals for heavy duty industrial motor drivers!

Of course I might put some of these features in a firmware for the old AMC1.5 in the degree that the current pin connections allow it.

May I ask what these functions are?

With 2 other microprocessors on the board you must be thinking something big!

Good to hear the development is back on track! I think the pre-programmed kits will be very welcome!

The two Attiny45 are for the encoders... will count 16bit positions and talk back to Atmega644 with I2C...

I plan to make the new boards smaller actually! Professionally made here in greece with two or four layers.

Functions? Well its a servo motor controller. It will do that as fast and accurate it can be done! The other additions are to make it easy for everyone to use it! If you have any other functions in mind that I'm missing you can suggest them!

hi

thanos put me on the waiting list for the first compleate kit you build as soon as you sort out the pricing let me know ill paypall you

wow great idea tronicgr!!

you already have a buyer

<-------------


thanks

I was thinking about more specific functions regarding the Atmega644, that make it the only one suitable. Eg: PWM hardware, processing power, number of I/O, Bootloader, etc..
Servo motor controller and easy to use are very open definitions of functions/features.

You already outlined the main functions like bootloader, usb-serial connection, encoders, industrial outputs, so not much more to add there. :thbup:
The key will be reliability, ease of use, and customization.

Couldn't it be done in the Atmega644?

Thanos great work !

how manny axis will it control ?

best regards Ad

Well, Atmega644 is one of the last big ones that can be still found in PDIP format! Soldering SMD parts its not the easiest thing to do!!

Yes and no. I'd prefer not because I'd have to use interrupts to capture the pulses that will slow down the main code too much. Its easier to have some slave devices doing this in real time and only fetch the data to Atmega644 when its needed.

Two...! I could use up to six but I'd have to sacrifice precious timers that handle serial commucication and interrupts!!

What I have in mind for more axis is to daisy-chain two AMC boards for mixed 3-dof systems. For indepented axis its not necessary!

Hello Thanos and all the X-simers

First of all thanks for his work in creating AMC 1.5 and H-bridge and everything else, I wanted to ask if you could list the general characteristics that should have this new control board.

I weighed that you could add:

- Reserved ports to the limit switches
- Emergency button
controlled by the firmware if possible.

To control the motors continue to use H-bridge 1.2?
or will be fully implemented in the new control board?
:hi: :clap: :hi:
Thanks for Everything

-Yes, Limit switches are required for the quadrature encoders, to measure the limits as it differs for every simulator!

-Emergency button? Just connect the emergency button to the power source or if you don't have a heavy duty one, cut the power to the AMC! :lol:
Controlled by the firmware? What are you mean?

-The DSMhb will be redesigned too into a smaller board, easier to assemble and use. But the new AMC connections will be backward compatible with old DSMhb1.2b ... So no worries!

I agree, PDIP is nice and easy to work with, but more importantly you can change damaged chips! You can also place components under them to save more room. Well, I guess size wouldn't be an issue with SMT...

There are different ways of reading the encoders, both in hardware and software. I'm only speculating here, but I think you will spend more processing time with I2C.
Of course it also depends on the encoder, it's CPS, mechanical/optical etc.


Anyhow, looking forward to the first release!

Thank you Thanos for your hard work. I'm looking forward to the new version.

Can I make a request for the DSMhb to be beefed up to handle 100+amps continuous :yippiee: ?

Never say never... You might surprised!

Tronic I have been watching all your work here for some time (2 years )but i am now ready to start on my 3dof and seriously just ready to purchase Ians boards and software. I have my actuators and was going to order the Sabertooth motor controllers.Question? How much longer should i wait for your new boards , this sounds to good to be true ,2 boards daisy chained for a 3DOF . Ians is great but Xsim has more profiles ,now you got me all excited!

Hello, you can help me ?
I have a simulator 2DOF to 2 motors 24v, in the H-bridge the IRF4905 and IRFZ44N is burned. I have changed motors 24V by motors 12v (for me the power 24v is too big ), I have changed IRFZ44N by IRF3205, test with motor 9v and power 9v the H-bridge work, when test a motor 12v and power 12v, the H-bridge no work. I saw that it fauld to uses IRLZ44N. It is possible working with IRF3205?

Ok, so I've just replaced the old Atmega8535 and the 10K Trimmer Resistor with new ones and I still can't get any response when I turn the pots in their full range of motion. I have gone ahead and ordered new pots (Bourns 3590S-2-104L). As you can tell, being the amateur that I am, I am grasping at straws here. Any further help would be greatly appreciated. I couldn't find any other firmware other than the one mentioned in my earlier post on page 110.
