Re: Stepping up to 24V

George Cushing
 

Think that's smart. Batteries will give a circuit all the amperage they contain if asked. That's why you can weld things together with them. I've been reading up on the ESP32 and it's designed to need very little current. Certainly, the 1A available from the NCP1117 is enough. The only reason the D1 R32 is powered by 12V, is that most people don't have 3V3 power supplies and it's handy to have the 5V for shield logic.

That is the ESP8266 you are installing. I do not see the ESP32 there, which is the problem.

The text for preferences has gone stale. I have corrected it in the Wiki. Thank you for finding this. Hope this gets you going. The corrected line is:

Hello Drew, good afternoon, what happened to me is that when I downloaded the library, it usually installed as shown in the image, but when I go to download it instead of getting the blue download bar as in the image, it appears in red this that I indicate to you has continued

java.lang.nullpointerexception

I am curious about your resin printing setup. It will be my next step in the 3d printing adventure and I know almost nothing  about it.

Not sure how many of you build one of Jerry's very nice hand controllers. I did and had meant to design some proper, longer buttons for it for a while.  Well a finely got to it and you can find a cad model here.  The cad files are there as well if you wish.  these really need to be resin printed I think as some of the design elements are pretty small.   If anyone need a set, I'd be OK with printing a bunch.  I can print 12 in about 3 hours ;-)

I am having some trouble understanding your problem. It may be lost in translation. Are you unable to install the ESP32 hardware in the Arduino IDE? The Wiki is a little misleading (I have corrected it), It is not a library but is hardware installed under the "boards manager".

Here is the relevant instructions from the Wiki:

You will need to have the ESP32 firmware installed. Under the menu File->Preferences open the dialog and add this line in the "Additional "Boards Manager URL's" text box: "http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://dl.espressif.com/dl/package_esp32_index.json" (no quotes). The ESP32 firmware can then be installed from the Hardware Manager in Arduino IDE. Select the "tools" tab, go down to the "Board:" selection. The "Boards manager" will be the top selection. Click it and enter "ESP32" into the search box. Install version 2.0.0 . This is very important! Later version have problems with the serial port that the Wemos uses.

Well Gentlemen, so far so good!  All these little details!

Interesting how the upload messages look completely different.

Thanks again,

Hi, I'm working on this, https://onstep.groups.io/g/main/wiki/26762
But the problem I have is with the arduino IDE, I wanted to install the ESP32 library and when I go to install it instead of showing the download bar I get it at the bottom left
java.lang.nullpointerexception. All the best

There are 2 voltage regulators on the D1 R32. The first is a MP1482 with 5V output, max input 18V. The second is a NCP1117 3.3V output max input 20V. so you are wise to keep the power in at 12V.

The screw terminal on the CNC3 is rated to 35V. To get power for the shield I've been tapping the mount lugs of the D1 R32's power jack.

Heating the lugs and giving the board a tap will clear the hole in them for connecting your leads. The leads can power your step up buck. This model seems to fit your needs and has screw terminals in and out.
Thanks George.  Most of the Wemos D1 R32 searches mention 5-12V input voltage so I will just stick with that and apply the 24V only to the CNCv3 input connector.  That should go just to the external inputs of the TMC2130s and nowhere else as far as I know.   I will receive the step-up converter next week. 

Thanks everyone for confirming that this should work (at least no one told me it will fry anything - I buy 2 of each usually so one failure is OK).

Chris linked me to this youtuber Deep Space Dad and he has some CGE PEC videos that look to be the same as the Pro PEC.

Re: ASCOM interface sluggish.

Yes... In lower Left corner select the 2.4.2 version and click install. The 2.4.2 will overwrite the 3.0.0.
Close and re-open the .ino file and try again.


Re: ASCOM interface sluggish.

Robert Benward
 


So this is what I have installed (version 3.0.0).  Should I change the version to 2.4.2? and reload?

Re: ASCOM interface sluggish.

 

I don't know which build you are using, but take a look at this thread. The easiest way is to take Wemos out and flash it through it's micro USB port.

Make sure ESP8266 library v2.4.2 is used (in board manager). Newer libraries causes similar issues which results in instabilities just as you described.

  • In boards select Generic ESP8266 Module
  • Flash Mode: "DIO"
  • Erase Flash: "Sketch + WiFi Settings"
  • Flash Size: "1M (64K SPIFFS)"
  • Reset Method: "ck"
  • Upload Speed: "115200"

Make sure to use this SWS (not the one from addon folder)
Make sure Wemos is in bootloader mode while flashing SWS (pin D3 must be shorted to GND while flashing SWS)
Make sure MCU UART which you use to connect Wemos to operates at same baud rate as Wemos (set them all to the same value).
Check your PCB diagram to find out which pinout it's use and disable swapped pins
If You have custom build, do not use UART0 which is normally used by MCU's USB serial.


Re: Sky Safari GOTO limits

 

Nothing is overlapping in my config. I hope this diagram will make it more clear, as this is how I see it. From the comment in config.h, these values can be in range 90..270 and -90..-270:
-270° and 270° would be a full circle (whole dial)
-180° to 180° would be half of a circle (9-3), which is also the default for GEM.
-90° to 90° would exclude any motion of that axis.

The complication is probably here because this same constant is used for both AZ and RA calculation.


Re: Sky Safari GOTO limits

Robert Benward
 

Vladimir,
No error is reported.  I went back and checked again, and it seems +/-180 covers the whole sky.  +/-160 does not.  I am just not clear where zero is.  Is that at the Zenith? 

If you use +/-210, that is more than 360 degrees,  That overlaps and I am not sure why you would need to do that, or even if Onstep will accept those numbers.

ASCOM interface sluggish.

Robert Benward
 

Hi All,
I am having a heck of time getting my ASCOM hub working.  I finally got it to do something, but I keep getting message like the ones below that I fail to open a client socket.  I am trying to run a PHD calibration, and it extremely sluggish,  Everything seems to be timing out.  The SWS seems to connect immediately, but my Sky Safari takes forever to connect, and it seems I am having the same issue with ASCOM and PHD.  The IP address comes up as 192.168.50.55:9999.  I assume the 9999 is a port.  Do I need to do something on my network ease traffic to the Onstep? I also see that the Sky Safari does not like it when the SWS is active, it will disconnect on it's own, and then refuse to reconnect without reboot the Onstep.  FYI, my ASUS router came default at 192.168.50.1.
Any ideas?

Thanks,
Bob

Re: Stepper Drivers, MaxESP. A note of caution?

Khalid Baheyeldin
 

Agree ...

As I was looking at the pictures you posted, it was very confusing.
No clue whatsoever on which way the module goes: no labels on the pins, no coloured pins.

The other two (MKS and FYST) have a different colour on the pins of the logic side.


Re: Stepper Drivers, MaxESP. A note of caution?

I agree , i am just adding the general information that the bigtreetech ones have no obvious markings or coloured pins which could cause confusion to less experienced users.
