Re: Alternatives to STM32 #EQ3

Wrong title.

If you mean on the Blue Pill PCB, then yes, STM32 compatible microcontrollers will work.
It has to be 128K of flash memory.

A better alternative is the RobotDyn F303CC module.


Re: Please help how the confing.h settings for EQ-2 should be #eq2

Marius Ungureanu
 

Hello, i am just starting a project based on ramps 1.4 and eq1, i wonder the following: eq2 like eq1 can’t make a 360degrees turn on it’s DEC axis, it has just a few degrees of turn on eyther side, is this a problem for a GoTo project?

...erratum the wire is 30 cm and not 30 mm


Re: Another GPS Module: AGM336H

Good to know, i'd like to test this module 
On the paper it is written that the Neo6 can get a fix after 18 seconds,  i tested this module indoor and outdoor and was not disappointed, around 30 seconds for time and date and between 2 and 4 minutes to get the location after the triangulation of several satellites.
In my setup I soldered a 30 mm wire on the central pin o the antenna and leave it outside the box (i had nothing better around me), actually it helps a lot

Can I use CSK32 or CH32 to replaced STM32?

All that's left is a halleffect sensor.
I hope everything goes well.

Hi Howard,

And I noticed you use /index.htm (and .htm in general for other files) and not the /start.html I see when the error occurs. That hinted to me i might have something left from previous uploads in the flash, so i chose the option to erase everything in the flash memory.

Apparently that worked as i got the page up just fine after restarting the divide. I'm using the board version 2.6.2 but i guess this will work with 2.7.4 too. 

I will try the SWS but not now as we have a streak of clear nights here for the next week and i don't want to miss it. Clear nights in PNW are at a premium lately :)

Another GPS Module: AGM336H

Khalid Baheyeldin
 

I tested the AGM336H GPS module with OnStep on a FYSETC S6, and can confirm that it works.

How is this module different from the more widely used NEO 7M ones?
It is very small (15.7 x 13.1 mm), works with all the satellite constellations (USA, Russia, China, Japan, Europe), and comes with a ceramic antenna that can fit inside the box (one less cable!)

They claim it can get a fix from cold start in 32 seconds. Testing indoors, it is much more than that.
About 1 minute 50 seconds, but at least it does get a fix. The NEO 7M with an proper external antenna
usually does not get a fix for me indoors.

It is also somewhat cheaper, but not by much.

Here is where you can buy it on eBay, and a page with the specifications.

Based on the many contacts I've had with OnStep builders a majority of conversions have been performed on GP copies. So there are hundreds of people here who have experience they can share. Don't be afraid to ask for help.

Like I said, it's been a while... guess I skipped that.  Regardless, you have set AXISn_ENC_DIFF_LIMIT_FROM so OnStep can't sync (any large amount) to the encoders.  The only difference is that the OFF setting doesn't allow you save the "zero" and that limits you to having to physically orientate the encoder body.

I have no intention of going back to the existing Wifi and Ethernet addons to patch things at this point.  Use them as-is or try the SWS (which has the call to setZero now) and see if it works.

Re: Max ESP 3.03 - PEC pin?

The MaxESP3 brings out the PEC input on the DB9 connector.  The design has a 0.1uF capacitor for some basic ESD protection.

Refer to the MaxESP3 Wiki, near the bottom of the page:

Max ESP 3.03 - PEC pin?

a.galavotti1@...
 

Hi Friends.

I'm using a MAxEsp 3.03 board and I would like to try Periodic Error Correction  in my old EQ5.

  • Could someone tell me which board pin should I use for ?
  • Is it possible to connect it directly to GPIO 36 (ADC0) of ESP32S?

BTW Thank to all Creators and Contributors to this great community: first time I suceed in moving a pair of steppers.

Re: eq 4 mount help

James Lancaster
 

If it's got a large pin that ra attached to, like the meade 6600, I can upload files for RA at least (my dec was diy). (Thought I had, but can't find it on thingiverse.) I think the mount, a licensed Mizar was the basis of the original EQ4. Though EQ4 is a lot more shrouded in history for me, than any other. 

(If you edit and re-edit posts, it sends an email for each one.)

Hi Sami,

could you be somehow  be more precise? There are serveral EQ-4 versions outside. Which manufactor? Probaly a link to the exact product and a photo would be helpful. I searched for you in Google and Yeggi.com but did not find any STL. Sorry.

For a "ready to go"-solution you can look here: http://www.astro-electronic.de/eq4.htm This gives you probably an idea how to realise it. But I personally would work with a belt and pulley (GT2) - not with gears (belt/pulley -> almost no backslash :-) ). You should be able so to construct something with Fusion 360 (Hobby-Version ist free). As long as there exist some holes for screws it should be possible. 

Cheers Axel


Re: CGE- Celestron => OnStepp electronics

Nice!
In my case, the stepper motor is raised by 3-4mm. Its upper surface is aligned with the cover of this space. The lower compartment allows the motor wires to go on this side, to the connector. Due to the length of the strap, I had to allow distance. Because of this, I had to cut a few sides. A 2-3mm air gap was formed. It’s not annoying because there’s a black engine in the back. I highly recommend drilling a recess in the axis of the worm gear into which the screw that secures the pulley sits. There must be another screw. Because vibration occurs, it is dangerous for the screw to unscrew and jam because the space is tight. For good axle adjustment, I added an angle profile with a screw to adjust the good position of the rear of this axle. Then the stronger bolts are tightened alternately. It is tested all the time if the turning of the belt drive is soft.
