  1. Code now updated to include any number for filters. Change the following settings to suit your setup // SETTINGS - MAIN PARAMETERS #define stepsPerRevolution 2048 //set number motor steps for wheel to rotate once #define numberOfFilters 5 #define offSetResolution 5 //number of motor steps for one offset change #define homingOffsetSteps 56 // number of steps from homing point to centre of first filter #define buzzerConnected 0 //1 to enable on pin 2, 0 to disable #define ledConnected 1 //1 to enable on pin 3, 0 to disable // SETTINGS - MOTOR #define IN1 9 // unipolar motor pins (set all pins) #define IN2 6 //motor driver step pin #define IN3 8 #define IN4 7 //motor driver dir pin #define motorType 1 //1 for unipolar, 2 for motor drive board (e.g. A4988) // SETTINGS - HALL SENSOR #define analogSensorThreshold 430 // set the threshold below which the homing sensor is triggered #define HALLSENSORTYPE 2 // SET to 1 for ANALOG HALL Sensor, CHANGE to 2 for DIGITAL HALL SENSOR #define HALLACTIVETYPE 2 // SET to 1 for ACTIVE HIGH Digital Sensor, CHANGE to 2 for ACTIVE LOW digital Sensor
  2. Hi this is possible, the current code is hard coded for 5 in several places (bad me), but I will try and have time to update to a more general code for filter numbers up to 8. Do the official filter wheels do magnetic sensing?
  3. Line 8: the 4 sets the mode of the Accelstepper driver to Unipolar. Line 22: #define analogSensorThreshold 430 // set the threshold below which the homing sensor is triggered set threshold for trigger if using an analog Hall Sensor (analog is 0-1023), with no magnet it will read ~512. #define HALLSENSORTYPE 2 // SET to 1 for ANALOG HALL Sensor, CHANGE to 2 for DIGITAL HALL SENSOR #define HALLACTIVETYPE 2 // SET to 1 for ACTIVE HIGH Digital Sensor, CHANGE to 2 for ACTIVE LOW digital Sensor change to suit hall sensor type. ine 26 const int filterPos[] = {0, 56, 466, 876, 1286, 1696}; //Rough alignment of filterPos rough position of filter positions from Hall Sensor (sensor, filter1, filter2, filter3, filter4, filter5). used to set rough position of filters in motor steps from home. The position offsets are later used to fine tune these values. line 85 stepper.runToNewPosition(stepper.currentPosition() - 500); //back magnet off sensor used to move the magnet off the sensors so that if by chance the sensor and magent are aligned we can remove the signal stepper.moveTo(3000); //set move to as 3000 (one rotation is ~2000 steps so if not homed by then raise error. do just over one revolution of the filter wheel looking for sensor signal. We must find the homing signal by then.
  4. Thank you, I like all controls in one place for my Astro rig and also if I use a remote set up I couldn’t access the dew controller. That was the reason for writing the driver. I hope others find it useful. After talking with Jasem (Indi) the driver will be available from source (Indi Github) or through the nightly builds (PPA details) and in the upcoming stable release on 31st March.
  5. I have just finished writing an Indi driver that implements all features of the mydewcontrollerpro 3 fw 340+. The driver is now included in indiLib under auxiliary drivers.
  6. I actually used duct tape for the focus ring on the lens for the time lapse. My children were around and one small hand could spelt an out of focus horror!!!!
  7. No, standard photo tripod, re-centre between captures. Then process in PIPP to centre and crop frames plus produce video.
  8. Isn't that what duct tape is for?
  9. My Efforts: Still: Canon 6d, Bresser 127 mak (1900/127), 0.5 x reducer - supplied filter Time lapse (Canon 80d, 15 secs interval, 400 mm lens, Bader Astro film). Time lapse.m4v
  10. I like the effect!! This is my effort: Time lapse.m4v Cloudy at the end.
  11. Hi Sorry, I attached the github html download not the correct xml file. Here is the correct XML file.AstroThreads.xml
  12. just to add my experience: I have printed threads, 1.25", 2" and M42. In my experience internal threads tend to shrink a little making them tight. To alleviate this I created an 8G tolerance for internal threads to account for this. I also print if possible with the threads around the z-axis with a 0.1 mm layer height. I have included my fusion 360 thread file with 8G tolerances Astronomy Fusion 360 Custom Threads.xml
  13. ooh, not seen that one..A 3d printer has been very useful, I have printed... SWeq5 motor mounts, dew shield, m42, m48 adaptors, dove tails, flats boxes, screen bezels, lens adaptors for asi294, telescope back plates........and things I can't remember. Before I had a 3d printer, I didn't know I needed one, but now I do!!!!
  14. I own an Ender 3 v2, and drilling plastic boxes is thankfully a thing of the past. Now I just boot up Fusion 360, find my calipers, grab a coffee and an hour later off to the printer and a while later I have the perfect box.
  15. Hi, you just need to cut the traces and then use small wire to jump across to nearby track.
  16. I buy cast iron round (100 mm diameter) on ebay, I then drill centre out to require diameter and drill in from side and tap to M8 and fit screw knob, I have just one for my samyang 135 mm on my SW eq5. I usually also give them a clear laquer coats to stop rust. Weight is around 1 -2 kg depending on thickness of round. Cast piece for this was £12 including postage. (100 mm x 1")
  17. Note: I have not used stripboard for years, horrible stuff, much better solutions out there now.
  18. I bought these boards for prototyping: Protob oards Amazon very little cutting of tracks needed, I have pictured a possible layout for you. I could probably put that circuit above on these boards in under an hour.
  19. I can highly recommend the ender 3 v2 3d print, just make sure you get the latest main board with it.
  20. Hi, I spend along time looking for a way to mount by new 135 mm lens to my mount with my ASI294 attached, I could only find a commercial 3d printed one. So I used Fusion 360 to make my own. I have included the STL files on thingyverse (https://www.thingiverse.com/thing:5205883) (Not up for 24 hours as I am a new user). I printed in PLA on ender 3 v2, 208 deg nozzle, bed at 65 deg, 0.2 mm layer height and 20 % infill. I used M4 bolts to attach rings to dovetail and M6 nylon bolts to secure lens into the rings (Note: don't over tighten nylon bolt in ring near front of lens as it stops the focuser turning). hope it is useful to someone! large sma135 ring_with M6 thread v2.stlSmall sma135 ring_with M6 thread v2.stlsamyang dovetail v1.stl
  21. Hi There, Sorry for the long time for a reply, work, christmas and Covid has got in the way. I have wrote the basics of a arduino library for accessing EF and EFS lens. I have also wrote a sketch that can communicate with Ekos via the Myfocuser2 protocol, it allows you to do the autofocus routine with a canon lens. I have attached the current files for your enjoyment!!! Canonef.cpp Canonef.h main.cpp
  22. Finally managed to have time to progress this project. So far: 1) Figured out the protocol and code to send commands and parse replies. 2) I can adjust aperture and focus. 3) Implemented routine to find current focus position. 4) Implemented routine to move focus steps +/-. 5) Implemented routine to find total number of focus steps. On the lens I am using the focus motor is not that precise. IMG_0225.m4v IMG_0226.m4v
  23. Here is a photo with a asi120mm and 2x Barlow connected. One thing to note with Indi is to put the driver into auto search mode, I have sometimes 4 arduinos connected (mount, focuser, dew heater, filter wheel) and the driver needs to hunt for the correct one.
  24. Thank you, I am currently modifying the cad to take 2" filters, the firmware will be the same.
  25. I cut a new focuser hole in my 130p to upgrade and solve prime focus issues. Here is the details about how I cut the actual hole :
