???

Just connect the 8825 as shown in the diagram and there is no problem, just adjust the current for the stepper motor correctly !

Thanks for your swift reply.
I have went through it.

As for using the DRV8825 , is the fast decay needed to be tied to 5V to have a stable tracking?

I am facing an intermittent tracking problem with my DYI ASTROEQ  using the DRV8834.
In order to achieve the 1/4 and    1/32 step, I did not connect M0 in order to let it float. When I track, at times the tracking is ok but some times the RA moves faster and some times it moves slower. Could this be a result of not connecting the M0?


Looking forward to hear form anyone.

Thank you.

If it's working with V1.29, then its an EQMOD issue, not an AstroEQ issue. There is no difference between the two in how the AstroEQ communicates.
The compatibility issue previously reported was due to a new feature in EQMOD V2.00 that conflicted with a command (now changed) used by the configuration utility.

Its possible that there is an issue with the "special version" of v2.0, I have no idea what changes Chris made to that for you. Or it could be as simple as an installation problem.

Cool, thanks Tom, It'll give me a place to start.

What do you mean by "EQMOD can't find any ports"? I presume you've set up the EQMOD settings and selected which COM port it should be using?

     I mean that neither EQASCOM_Run nor the Toolbox can see Astro-EQ...I tried to on every port (all 16) and no communication between EQASCOM and Astro EQ. Yes I DL'd the newest Config Utility and firmware. It works fine...connects on Com 8 every time, but when I finish it won't even go into Test mode because EQASCOM cant find the Port. It just shows "No Com Port Available (or Found)" I dont remember what the status light was doing...I re installed a special  V1.29a that Chris (EQMOD) made for me and it workds fine but I don't get all the new whizzbangs in V2.00.
   
thanks,
Rick

Hi Rick,

Sorry it takes me some time to respond, I am exceedingly busy at the moment..

What do you mean by "EQMOD can't find any ports"? I presume you've set up the EQMOD settings and selected which COM port it should be using?

Sometimes switching between versions can cause problems with the EQMOD.ini file. You could try making a backup of the EQMOD configuration and starting fresh - say rename "%APPDATA\EQMOD\EQMOD.ini" to something like "%APPDATA\EQMOD\EQMOD.ini.bak", the load EQMOD again and it should create a new file. If that doesn't help, you can rename the backup back to restore your previous setup.

I presume having downloaded the latest config utility that you've run the update firmware button to ensure the latest firmware is on the AstroEQ?
What does the status light of the AstroEQ do when you try to connect EQMOD?
When you configure the AstroEQ settings, you'll need to make sure that the Advanced HC Detect option is set to disabled (the default) as the old controllers are missing a resistor which is used as part of that detection.

With little information to go on, I can't offer any more advice.
