Hi Here I share with you a 3d model I did for my rotator. It is designed having in consideration the PCB for DRV8825, and for a rotator of M42 thread. I tested and it works. I included a gap for the home sensor, and also it has a box attached for the electronical parts. Best regards, Joaquin. P.S.: Forgot to mention that I needed the rotator and an 10mm extensor M42 to fit everything. The pulley I got it from here: https://www.thingiverse.com/thing:5243794 And this is the rotator I used:

I tried different things, and stuff that works the best for now is 1/4 steps, motor speed delay 1500. Motor-shaft-360 is 1600 rotator-360 is 12000 Now I got to make home sensor to work ..

Hey there, after few days of trying to make this work and looking for answer in the forum, I'm creating a new post. Config : DRV8825 with nema14hm11-0404s motors. Arduino nano The build went very well thanks to an very well detailed manual (thank's Robert !) I'm now setting the rotator on the windows app, but motor get way too hot, I can barely touch it 800 steps configured in myConfig.h I tried half steppng, ful step mode, lowered motor speed delay, increased it, the motor kind of vibrates, making...

J1 PRG Switch This is a circuit that prevents an upload of the firmware, when switch is closed. When open, the controller can be uploaded with new or changed firmware Regards Robert

Vin is the means to power a 12V NEMA stepper motor. There is a limit on how much current the board can get using USB. For older USB types then the limit is low. But USB3 and C provide a lot more current and when used with ULN2003-28BYJ-49 motors then 12V connected to board may not be required. The messup re 12V and when to turn on has more to do with the USB connection and Arduino chip components, and not the project. As you have found, there is a solution that you discovered. If you have no need...

Alberto Peralta Martin posted a comment on discussion General Discussion
Hi, I'm building the rotator, everything is great! But I have a question about the Vin pin. Why is it connected? I've tried not connecting it, and it works perfectly with USB power. However, if I connect Vin, if I connect 12V first and then the USB, it doesn't work. The Arduino shuts down and doesn't connect to the PC. I have to unplug the 12V and reconnect them. That is, I have to connect the USB first and then the 12V. Is this correct? Why does this happen? That's why I'm asking if it's necessary,...

Ok, I found out the problem: the light led I was using was meant to be used for a lower voltage. So by now everything is working fine, except the J1 PRG Switch but I think I will leave this without using it. I am finishing a 3D design I will share as soon as I have everything ready. Best regards, Joaquin.

Hi, Finally I have my rotator fully working but with a small problem. I use a DRV8825 with a NEMA 14 working fine with PCB Gerber. The only problem is the board fries my LEDs as soon as it start the power. With a tester I measured 11.53 volts. Tryed different LED lights with same result, they are fried. Any help? Finally in the PCB there is a second interruptor which doesn't seem to do anything, conector J1 "PRG SW", Is that all right? Best regards, Joaquin. P.S. I am trying to make a 3d design for...

Check proper wiring connection, I had this issue with a Nema 14 steper motor and it was caused by a wrong wiring connection.

Extract the zip file, go to a subfolder called "Application files", then go to the subfolder "myrotator 2.4.0.8", there just rename the file "myrotator.exe.deply" to "myrotator.exe" and it will work flawlessly.

Hi everyone! Does anyone eperiences temperature issues with the stepper motor? I run the hardware with the ULN2003 driver board and the 28BYJ-48 stepper motor. Setting "coil power" on or off does not make a difference. The moter still gets very hot! Help/recommendations are very much appreciated :-) best Klaus-P.

Hallo Ralf! Schau mal meinen neue Post bzgl. der Windows Application an! Gruß Klaus-P.

Hi Bob! Please check the latest versions of both Windows-Applications. Most likely there is a bug in the Software! I found some earlier versions on m harddrive (myewControllerPro3 3_0_7_6 and mDRotator 2_4_0_5) and both of them can be installed without any problems. Best Klaus-P.

Hallo Ralf. Ich kann leider nichts zu Deinem Thema beitragen.... Aber kannst Du die Windows-Aplication bei dir installieren? Ich habe leider die in meinem Chat beschriebenen Probleme. Daher kann ich den Rotator nicht benutzen. Wäre suoer, wenn Du mir antworten könntest. Danke und Gruß Klaus-P.

Hello Robert, I had the same problem as Julion Hornos, that the stepper just jerked. Perhaps it should be added to the otherwise really excellent instructions that the cable colors for the motor windings specified there are not standardized. I had A1 red, A2 blue, B1 green, B2 black. In the config.h there is a separate DRVBRD for 8825 for stripboard. Is there a difference?

Ok, now I have everything working. My problem was the pins of the Nema motor were different number than the ones in the manual. So I took a look at the datasheet of my Nema motor, put the right order of the wires in the J4 connector and now it is working!!! I just need to assemble everything and print my case in my 3d printer. Thanks, and I hope my case can help someone else. Best regards.

Ok, I got the windows app working!!! So now I have connection to the board and everything works fine, except that the Nema motor make noise but does not turn. I get no clue why it is not working. Any help would be much appreciated. By the way, my set up has no Home sensor, I am not sure if this coould be the problem. In the Windows app is set that no home sensor is available. Thanks in advance.

Thanks Robert for your support I will take that into account

Hi Julio Coming home from the angles <180 stop in left side of the sensor and coming from angles >180 stop in right side of the sensor, so the home position is not always the same. For doing that the only posibility is to move to angles from 0 to 360 always in the same direction (right) and that way the home position will be always on the left side of the sensor.> I dont think anyone seriously supports the 0-360 rotator any more. The major problem with that is the cable wrapping. Software is easy....
-
JJX No, not really. I think there is no need to use motors with 2A. And the pdf does say that the driver BED needs a heat sink if running with 2A motors. In a lot of rotators it may be possible to use a simpler 5V motor running off USB. I'm sorry to say that time and effort (which is in short supply) are just not there to implement that further Regards Robert
-
Hi Julio One possible explanation for the issue is that the reset button is easy to slide and probably i tried to connect with the reset pressed and this can affect to the eeprom. Is it possible? I hope that this not happen very often.> No should not occur. The reset button is not "reset". All the switch does in like a "write protect" meaning that when set to the On position, reprogramming the Controller is disabled, EEPROM changes are occurring regularly during use. The Save EEPROM code tries to...

Dear all, Now that all seems to work I am testing the home button from different angles. I have notice that the home position is different coming from angles <180 and from angles >180, this is due because for angles <180 the rotator move in right direction and for angles >180 in left direction to arriving faster to the correct angle, Coming home from the angles <180 stop in left side of the sensor and coming from angles >180 stop in right side of the sensor, so the home position is not always the...

Firmware -2024-09 is the latest here The issue of the home sensor working ok for the 1st time. and then motor only moves 1 step for other home commands. I think this is connected to the home sensor detection. I believe that the Home Sensor, once detected, stays ON when found at Home, and stays on when the rotator moves away from Home. so next time a HOME command occurs, the firmware thinks the focuser is still Home.

Good afternoon. I have seen that there is a new ascom driver that solves the reverse issue. Let's see if the clouds go away and I can try it. As a suggestion, it would be nice to be able to modify parameters from the driver and not from the Windows application, so we wouldn't have to depend on it. Thanks and greetings

Thanks Robert, Yes, the sensor was the only element with no revision and it is in a very bad position, with a not clear visibility. It is not easy so see if the magnet passes close enough and the connection was not very stable.

Hello Robert. I am a fan of yours for the work you have done and what you have contributed to so that fans like me are encouraged to build our astronomical gadgets. That's why I refuse to not use your rotator. The rotator rotates very well, but I have not been able to get NINA to fix the frame, it only makes the rotation move from one place to another erratically. I have the "Reverse" option activated using the Windows application. What can happen? Thanks again for everything

Hello from France, and congratulations for all this work. Just found an old Brian Schmaltz PCB : Big Easy Driver from https://www.sparkfun.com/products/12859 in my garage. Do you you think it's possible to use or adapt it with the right stepper motor. The BED can handle 2A bipolar stepper motors. If I look at the schematic there is a lot of common points and it share the same original chip A4988. Thanks for your help. Regards

I am using the PBC DRVBRD_DRV8825 v103 with the Nema motor 14HM11-0404S. I have read in different places that it is necessary to adjust the Vref to limit the maximum current to the Nema motor. In my case, the motor accepts 0,4 A per phase. For DRV8825 the Vref=Curren_limit/2 For my motor Vref=0,4/2=0,2 V Are any of you doing that? I can't see any reference in myRotator user guide Thanks

As I have ordered more than one pcb, I am mounting all from zero to correct errors. One question, It is necessary to adjust the Vref? In my case Vref=curren limit/2=0,4/2=0,2 V

Hi Carlos Its actually not implemented yet for this project. It may be included n the next update, or it may not, I gave a reply to a user on this project that is possible to get a small footprint, and posted a picture of the LlilyGo as an example, but I did make it clear in the reply that the was not a work in progress. I think I said something like 'someone would have to do the work on that. I sometimes put placeholders (think like one of the small yellow stick note) for things that may be introduced...

good morning. I have seen that in the latest firmware, the LILYGO board is included. I have tried to compile with ESP PICO-D4 but it gives an error in myepromm.... no idea how to correct that. Does anyone know how to solve this? I take this opportunity to say that unfortunately I have not been able to get NINA to rotate the camera in the framing assistant, it turns erratically (I have the reverse box activated)... greetings

yes i understand! Thanks anyway for your kindness

hang on a sec, as I wrote above re LilyGo motor driver Would require firmware rewrite for use as rotator project) This rotator project has been written to run on an Arduino Nano. There is no support at present for any esp32 chips. That may happen at sometime but it is still a long way off even if that happens, It would be a significant amount of work to fully implement. At present the LilyGo its supported by the myFP2ESP32 focuser project only. Apologies if I had spelled that out, Regards Robert

i wasnt aware of the tmotor ... that would be awesome ! im ordering one to thinker with, i understand the pain to rewrite a firmware for different architecture... thank you for the inspiration!

Hi Marco I looked at that but it seems to be costly when compared to others, and I have found its much harder to port firmware designed for certain architecture types. When one goes down that path, there are a lot of obstacles and challenges due to differences in internal changes like timers, not to mention the use of 3rd party libraries and drivers not working on those chips. There are smaller options available, Such as Nano SuperMini (should run with minor rotator firmware changes and would require...

Hi Carlos When you say write limit, do you mean number of firmware changes? Every time you program the device that counts as 1 Everytime you write a setting (or multiple settings at once) that counts as 1 In earlier firmware versions there was counter implemented in firmware that kept track of the number of writes. Some Internet links will say 100,000. Some state 10,000. Some say different values for Flash (where the program is stored) and EPROM (where settings are stored). The chip used in the controller...

What a good explanation! When you say write limit, do you mean number of firmware changes? or to changes of state in the rotator (turns) Greetings and thank you very much as always!

Hello robert, i've seen your project and i love it ! also i would like to know if you are willing to port it to other platform, because im looking for a smaller solution and right now i stumbled upon an RP2040 integrated solution with TMC2209. actually is used in the Enraged Carrot Feeder (a funny name to have, indeed) The board is the ERB v1 by fysetc. it features a lot of IO and 2 integrated drivers, in a very small for factor and a wide range of input voltages. can you give a look at it and tell...

Hi Carlos Important settings are saved in permanent storage. At boot time, these settings are read from permanent storage into a memory based area. ( load_settings() in myRotator_2024_xx.ino ) When you change a setting, the setting is changed in the memory based area, and a timer interval in seconds starts counting, 1.. 2.. 3 etc When the count reaches 30s (this can be changed) the changed value is copied from the memory area into permanent storage. The permanent storage has a limited number of "writes"...
