Hello Robert, i copy the .cpp in the firmware dir. Flash again, but i am sorry, is the same. Move cw and ccw over the move Button works, without the Sensor enabled the Home Button works also, after enable sensor, no home button. The stepper make one tick, not more. Sorry. greetings Andreas

Hi The mistake is mine. really. It is.\ Attached is a replacement file for myrotator_comms.cpp I forget to strip out all the debugging statements that I put in when resolving other issues. Those debug statements write to the serial port, so the windows app, and ascom, that talk to the serial port received data that made no sense. Apologies, let me know it the problems go away (or not) Regards Robert

Hello Robert, I'm not sure if I made a mistake. I built the rotator according to schema 1.03 with DRV8825 and Firmware 2024-07 on astripboard. With the Windows App I can operate the rotator, move to an angle and home works. But if I set the "enable home senor", I can only do move, when I click home nothing happens, the motor don´t, the angle also. If I then approach the home sensor with a magnet, the angle jumps to zero and I can move again, the "find home on connect" doesn't do also anything. What...

Hi Klaus I cannot activate the home sensor. In the Windows application it says „true“ and „moving“ even though there is no movement at all. In the Sketch I type „:421#“ and it still tells „$0“ when I check with „:43#“. There is no change in speed no matter what I use (slow, medium or fast)..... Home Switch I think there is a typo wrong there, Looking at the protocol :41# $int# Get Stepmode :42int# Set Stepmode :43# $byte# Read Home Sensor logic state (true, false) :42x is used to se the STEPMODE....

Hi Robert! Since I’m a bloody beginner in respect to programming Arduino (honestly spoken -I have no idea 😊) I will stick with the USB-connection. I downloaded the Sketch – and it works (almost). However, there is the following issues… I cannot activate the home sensor. In the Windows application it says „true“ and „moving“ even though there is no movement at all.

Hi Why not use the Arduino PINs RX0 and TX1 with a resistor divider (1k and 2k Bridge) on TX of the HC-05 Because those pins are used by the USB connection. to read and control the focuser. I am not sure using 3v3 on those pins are a good idea. This means that with a Bluetooth connection no change/alteration of the Arduino code/Windows SW would be necessary…. The rotator code would need firmware changes to support bluetooth OR as the wiring on your dew heater controller were you used the PINs D12...

Hi Robert. Thank you for your immediate answer. This means that with a Bluetooth connection no change/alteration of the Arduino code/Windows SW would be necessary…. The rotator will work the same as with the USB cable – as discribed in your myDewController pdf (sorry I’m not that comfortable with such Topics…😊) Regarding the PINs for the HC-05….. why not use the Arduino PINs RX0 and TX1 with a resistor divider (1k and 2k Bridge) on TX of the HC-05 Hi Robert. Thank you for your immediate answer. This...

Hi Klaus Not so easy as I thought. The below is fairly long, comparing myFP2 against myRotator comparing pin usage etc. Should be simple if using UL2003 of L298N, difficult using DRV8825. I have never tried using different pins for Software Serial other than the ones for myFP2 (d10-d11) so cannot say for sure if other pins work. I seem to recall that sw uses a group of 8 pins and would not work if the pins were not in the same PCINT group, this 0-7 and 8-13 meaning you cannot have D2 and D10 as they...
-
Hi! I already build your MyDewController and I'm thrilled!!!! Since my USB ports are very limited I was happy to connect the dew controller by using the Bluetooth module HC-05 to connect to the PC. Can I also add the HC-05 to the myRotator layout/PCB and run the Arduino/WIN SW - ordo I have to adapt the sketch? Thanks Klaus

Robert, Wouldn't I need to be connected to the app to be able to set this? The error Im getting is upon connecting.
-
Hi Brannon myRotator-User-Guide-24-09.pdf ROTATOR SETUP pgs41 to 44 StepSize is a constant and should not be changed. It does not have the same meaning as in a focuser. In a rotator stepsize refers to (from pg 52) STEPSIZE Is the minimum movement of the rotator expressed as an angle (1 degree), as set as 1 degree The current firmware only supports 1 degree, there is no support for sub-degree resolution at this time. Regards Robert
-
Hey Robert, What page talks about the post config for setting stepsize?
-
Hey Robert! I sent you an email about test code for another issue and talked about this in it, but figured this might be better place to bring it up and with some more info. I ordered some Nano's and they are the newer USB C version. I created a stripboard with the Nano and a DRV8825. It was working fine and then all the sudden when trying to connect I get an error on the GUI of " Error invalid data", the log is showing it to be a associated with Case 25 Get StepSize. I thought that maybe my controller...

I ended up figuring it out! One issue was my Nano wasn't taking new code even though IDE was showing successful for some reason. The second issue is on myrotator_config.h line 24-25 I believe Since Im using a DRV8825 driver and stripboard I had uncommented line 25, but unable to connect with that to the GUI. I tried to use line 22 "DRV8825 driver with a NEMA stepper motor" and no more errors. I was reading it as line 22 is for when you are using a PCB and line 25 is for when you are using a stri...

I have two doubts. a) I have installed the hall sensor, but it does nothing... what should I do? I guess spin until you find the magnet... but it doesn't spin or do anything... b) On the other hand, I have seen that it only rotates the degrees that I indicate in one direction, that is, if I indicate 90º it rotates those degrees, but if I indicate 45º, it does not rotate in the opposite direction, but rather it rotates in the same direction 45º.

Hello, Robert. I'm trying to make the change so it works on an arduino pro micro... but I can't get it to compile. Am I getting into trouble? or is it feasible Sorry for insisting

Hi Jean The central pin is well connected to the -. Is that a typo error? You mean D0 on J5 Thanks for the information, because it does help to eliminate things. And you are correct about R3. That is my mistake. I have observed with the log that there is an issue detected. The issue is that after a Move home, it seems that the move starts but on the second read of ismoving the controller is returning 0 meaning it has stopped. That stop however occurs well before the move is meant to complete. I have...

And the "Find Home onb connect" in N.I.N.A. does nothing.

Hello, I will respond to your message in two installments, Here is my first response: I have a multimeter. I don't see an R3 resistor, so I didn't put one, Only R1 (4.7K) is in place. The sensor is only one chip, I added the 100nF capacitor between - and +. The central pin is well connected to the -. The small surface of the sensor is well directed towards the magnet. I will soon do the tests with the other firmware, but it seams that the magnet is well detected, I see it in the Windows application,...

Hi The :05# and :06# rotate the motor 360 degrees OK, but slowly. the :0330# command worked once, OK, but fast. I tried again thoses 3 commands, the :0330# did not worked anymore, even if I quit IDE and disconnect the arduino. Message appearing are ", CCW" and ", CW" The 05 and 06 worked, speed is not important. The 0330 moved rotator to absolute position angle 30 Then you repeated the commands but this time the 0330 resulted in no motor movement. that is expected Here us why The 05 and 06 are setup...

The motor speed delay is 5000. I tried on the app again, and I can give you precisions : The "Find home on connect" worked on the app. but after that, if I go to "rotator", move to 10 (for exemple) then click on "home" , the motor doesn't come back at home. If I try it again, (move to 20 witch works well) then press home again, a got a small move (one or two steps) then nothing, and the "Is moving" indication stays on "True". Impossible now to make a move (still thinks it's moving). I have to unplug...

Hello, I noticed something strange : When using the home sensor, It the motor run a very short way then stop, but the "is moving" stay on true. the motor sould continue running until the sensor is detected. but if I disconnect from USB then reconnect, the Home button works once, but at the second attemp (after moving to another value) it to the same. any idea? Is it a bug? Thank you. Jean

Thank you very much for answering! Precisely today I was going to provide this solution, since I had the same problem with a rotator using moonlite. I solved it by activating "reverse" in the driver. It's a relief to know the solution, since I like myrotator much better. One question, can the code be adapted to use an Arduino Pro Micro? I say this because I have PCB boards for focusers and they would be useful for this. Thank you so much!!!

Patrick PASC posted a comment on discussion General Discussion
Hello everyone. Just some information which will not help the development of the project but which may possibly give a clue. I have been using MyRotateur with NINA for over a year without encountering the slightest problem. I have remained at version 125- 1 of the firmware with the ASCOM 108 driver and the Windows application 2.0.0.2 As it works perfectly I remain on this configuration. However, when I moved to version 3 of NINA I had to reverse the direction of rotation of the rotator to that the...
-
Good morning. After doing some tests, I have been able to verify that the rotator rotates and behaves perfectly if it is rotated through "equipment", but if NINA uses the rotator to make a frame, it no longer works well. The sky position box appears. For this reason, as of today, it cannot be used in NINA. At least, this has been my experience. Thanks Robert for the projects you do!

Hello, Robert Yesterday my rotator worked great. For it to work, the "sky position" part does not have to appear in NINA. What I found surprising is that before going to sleep the rotator was correctly in NINA and when I woke up, it had changed! I attach some screenshots of what I found and right after, when I disconnected and connected again. I tell you all this in case it helps improve this great project. Thank you
-
Hello! Thanks for responding so quickly Robert! I am using the latest version of firmware (downloaded it 2 weeks ago). Since it works very well with the application, could the problem be with the driver? (I don't understand what you told me in your answer) I send you NINA's log. The screenshot I sent you corresponds to 11 p.m. All the best PD. I just reinstalled the driver and it seems that "sky position" no longer appears, only mechanical position. Let's see how it goes tonight!!

Hi As far as I know, the ASCOM driver I supplied is compliant with the Rotator Interface v2 of ASCOM. Interface v2 does not support the "mechanical" / "position of sky" I have just checked the ascom driver source which returns interfave version 2 for the method InterfaceVersion public short InterfaceVersion { // set by the driver wizard get { tl.LogMessage("driver.InterfaceVersion", "2"); return Convert.ToInt16("2"); } } There is NO corresponding method in Interface 2 for mechanical position.

Good morning. Yesterday I was finally able to test the myrotator project. My configuration is the following: - 28JYB motor modified to bipolar - Driver DRV8825 Modified firmware only for the pins. I have done several tests in my living room, trying to spin it and it works perfectly. The problem arose when I used NINA's framing assistant. It has been unable to reach the desired turn, making erratic tests. I have also been unable to see the relationship between mechanical position (it matches the data...

Good morning. Yesterday I tried installing the rotator on the breadboard. Everything seems to work well, except that the motor remains powered continuously, although coil power is off (the driver and the motor start burning!!!) Could it be a wiring problem? Apparently it's fine.... Thanks and greetings

Hi Sebastian The Ky024/003 module is preferred. https://www.joy-it.net/en/products/SEN-KY003HMS It has appropriate components on the module board to ensure correct operation. if you intend NOT to use a module board, then you will need to look at the PDF datasheet for the component and see what extra components are required for correct operation. regards Robert

Hello, I am building my second myrotator... great project, thank you. I am certain that I found somewhere instructions on how to change pinouts that connect to IN1 to IN4 on the ULN2002 so I can use an existing Arduino/ULN2003 board for a myrotator. In spite of much searching I cannot find it again. I just want to change the Arduino mcode to use pins D4 to D7 instead of D5,6,9 and 10. Can you help me with this? Cheers, Stephen
