Good question. But that is how things are, based on actual testing of how fast each microcontroller can actually pulse the motors. Counterintuitive, but that is how reality is different than theory.

I can't directly comment on the CnCV3 board, because I don't have one. But the 134 deg/sec is TOTALLY INSANE ... You must have input one or more wrong values to end up with that. Tell us what you used

Exactly right. The only thing I would add is that you need a visual reference object. Can be a nail on a faraway chimney, a utility pole, a communication tower, an artificial star or what have you. Yo

You don't have to. There are options you can add to make this totally automated. The BME280 sensor measures ambient temperature and humidity. OnStep calculates the dew point. And a thermometer measure

What I did to avoid that is pluging the dew heater in doors, and turn it on from OnStep. Then using an infrared thermometer, get an idea of where in the slider it would be ~ 3C higher than ambient. Th

I power the board from a 19V laptop power supply. I did not need to do anything different for the dew heater that I was powering it from a separate 12V power supply. You just need to use one of the ex

Confirmed ... I use the former on my V2.0 board now. I did use the latter when I was on the V1.2 board.

If you have a corridor or space in your house that is long enough, you can use my cheap artificial star instead of a terrestrial object. You can also try placing a mirror at one end of the house to do

Focus on axis1 only. Try with a combo of driver A, and motor A. Then try driver A, with motor B. Then B and A, and B and B. Instead of trying Unpark, do this: - Wait until the GPS stars to blink. That

I doubt whatever in there is still an issue. In my configuration, I have these: #define AXIS1_DRIVER_MICROSTEPS 32 #define AXIS1_DRIVER_MICROSTEPS_GOTO 8 #define AXIS2_DRIVER_MICROSTEPS 32 #define AXI

Works as designed now. Thanks for the fast response, as always.

If you are using an S6, I can say that BigTreeTech TMC5160s V1.2 that I bought around 10 months ago, work without the need to snip anything. Remember that both the board and the driver are for the 3D

No, it does not. There are plenty of supported options in every price range. See the last question on this page https://onstep.groups.io/g/main/wiki/7118

More current is usually associated with more torque, but not always the case. And with 2.5:1 or more gear reduction, the 51OzIn/36Ncm 0.9A 400 step motor is equally capable to the 62.5OzIn/44Ncm 1.68A

Those are really great, but kind of expensive, and you need to figure out if your board supports SPI drivers as is. 1.5A is the maximum on the LV8729, and you should be running any electronic componen

The S109 is used by some OnStep users. One of the largest mounts that run OnStep uses the S109 without any complaints. It is used for astrophotography. And it is a direct coupling, and the motors are

Wrong section of MyConfig.h. Actual value is: #define FEATURE1_PIN Heater0Pin

I am using OnStep 5.1m on an S6 V2.0. This is how the dew heater is configured: #define FEATURE1_NAME "Dew 1" #define FEATURE1_PURPOSE ANALOG_OUTPUT #define FEATURE1_PIN Aux1 It starts with 0%. When I

That is likely what this case is. Just to confirm, I loaded OnStep 5.1m on an S6 V2.0, plugged in the two BTT V1.2 TMC5160, and the mount works the same as it did on the V1.2 S6. Slews at 3.5 deg/sec

Not sure what that means ... can you explain?
