Otto, The ammeter is in line with the ground between the external connector and the PCB. Doing one axis at a time, one is looking for the current draw when slewing to be the same CW and CCW. This part

Khalid, I've ordered replacement LV8729s from Germany, should be here in a couple of weeks. Both axes displayed the same behaviour, even when I changed from one set of drivers to another. By changing

Hi, I've got OnStep running already on a Fysect S6 and I'm working on a case for it now. I have a small fan laying around and I thought I could use it for this build, but I know little about electroni

Ok, too bad. Regarding drivers, it shouldn't matter. If you didn't try it already, I would swap the bigtreetech to one of the working axis, try both focuser with fysetc and slew with bigtreetech, just

After tuning backlash and leveling base seems now it's tracking fine. These planetary gears from OMC have a terrible backlash but enough for visual. Thanks Khalid

Dave... Could you comment on whether you have dampers/flywheel weights on your steppers? and If you do, from personal experience perhaps you can help us in improving Guy Brandenburgs setup.

The MKS allows you to have both external power and USB connected at the same time BUT, you have to do it in order. I always connect my external 24v power first, and then I connect USB. Then the revers

I get the joke, I remember... :)

Thanks Khalid and to all who have responded. I've got a message into George. I'm thinking of the MiniPCB route.

Very nice Peter! On the volt/Amp meter, how do you diagnose if you are imbalanced? Are you looking at balance in both the RA/Dec axis? Do you have a picture of the internals you can share on how you w

These look interesting: https://motor.mtl.co.jp/dcms_media/other/%CE%BCDD_Motor_EN202006_B1.pdf Not sure what spec one needs to build a Plane Wave style mount though? Peter

Hey Everyone, So, Many of you supported me last year during my build of the Wemos+CNCV3 OnStep build which worked well, but even back then I was reporting the issue of having to reset the board everyt

Otto, I just completed my build using the MaxESP3. I was able to squeeze in a 4 digital Volt/Amp meter after modifying it:), which I use to balance my axes. In this build my drivers are external to th

David, I didn't hear an attack, but I do hear someone who is not listening. Khalid is just telling you what you want to design, is already existing. Khalid is, as I am, at a loss to understand what yo

I haven't tried out having the sequencer unpark my mount yet, but I have noticed I can't unpark if my GPS hasn't updated the time yet. In case I have to set date/time via app or SWS before it will unp

Screw-ups that happened, from what I remember, is not setting the USB 5V jumper correctly while connecting 12V. It is finnicky when flashing only if you have a chatty GPS (NEO 7M). You need to try sev

Oh, I should mention as triggered by the sequencer.

Does anyone else find the unpark mount option in NINA not working with Onstep? Peter

Guys, There is no attack here. This is surely not intended. My writing style is usually terse, and to the point. Sometimes this can be viewed as being rude. And the medium does not lend itself to nuan

For my initial testing i just sent commands directly to the serial port from the serial monitor in Arduino IDE then i used TeraTerm terminal emulator next i went to Stellarium and controlled the scope
