No need to throw it away just yet. You can unsolder pin 16 off the Teensy and jumpwire that hole on the socket to some unused pin and then redeclare it in Config.h. This can be easily done on rear sid

Setting to full (1.68A) may result in inaccuracies due to thermal protection, step skipping and overheating. Max output current should be set to somewhere between 30% and 60% of motor nominal current,

Which pins you connected TMC SPI bus to?

Try setting both GoTo microstepping settings to OFF (for the sake of testing) and see if there is any difference. Your slew rate will be slower though, but just test if DEC and RA will become equal th

So you want to say that you only have this problem when using it via ASCOM?

Let us see your config then

I think precision industrial robot requirements are somewhat different from AP appliances so the two categories are hardly comparable and see no point. But, you're right about expences. In AP field, t

What does mean DEC axis is slow? Is it pointing where it should, regardless of speed?

CNCv3 in combination with SPI drivers? Disable and disconnect GPS and see what's happening

Strain wave gearing (marketed as harmonic drive) has been around for a while. Frankly, I don't understand people's obsession with it. It's zero backlash feature is main selling point, but there are so

I believe that was typo. Here is how to finely adjust tracking rate (spoiler: not by editing steps per degree)

No, but if your board have temperature compensated crystal oscillator of good accuracy then you don't need a PPS at all. MCU already getting CLK from that oscillator and there is nothing to sync. Just

First you need to define RTC source in order to initialize 1Hz square wave signal to be used as PPS source. If you have DS3231 on I²C bus it would go something like this: #define TIME_LOCATION_SOURCE

No, you don't need different power supply or regulator. You can safely run everything with 12V PSU or car battery. Steppers are current regulated devices and drivers will take care of everything. Ques

Once again, do we speak about scope pointing encoders (on axis) or encoders for closed loop DC servos?

That trimpot on TMC2209 should be set to give Vref not highger than 1.0V for 1.68A stepper (thats equal to 60% of Imax), regardless of decay mode. Too high Vref can cause motors to stall.

Yes. Encoder support is implemented in SmartWebServer (i.e Wemos D1 Mini) and Max series have prepared leads for encoders on DB9 (MaxESP3, MaxPCB) or DB15 (MaxSTM) connector in PCB design itself.

When flashing SmartWebServer, use source from this link: https://github.com/hjd1964/SmartWebServer and use ESP8266 2.4.2 board version. Before flashing, short G and D3 pins with jumper wire, reboot We

They are supported in recent versions of OnStep and OnStepX in standalone mode and they works fine. It's not about OnStep version but about build. One can use them pretty much everywhere except in Max

This was meant for linear regulator 7812 or such which just disipate heat. PWM regulated step down is different. I had XL4015 from deep discharge battery reducing to 11.5 all the way from 11.8 and had
