I want to make sure everyone knows that I only stand on the shoulders of giants. I am learning more and more about electronics and how all of this works. Without all of the members of this forum I wou

I was wonder what the relative advantages of the Teensy 4.1 processor has over the ESP32. For instance, does the greater processing power affect: 1. Sidereal tracking accuracy? 2. Slewing rates? 3. St

Long shot here but I'm ordering this worm gear set 50:1 0.8 modulus and need the diameter of the driven gear. Problem is I'll have to wait a month to get the thing, then another month to order the cor

Hi All, I am trying to move a stepping motor by connecting BigTreeTech's TMS2209v1.2 to OnStep, but it does not rotate. TMC2130 and DEV8825 can be used in the same circuit, so there seems to be no mis

I have PEC on my MiniPCB, it works well, no autoguiding for me. On my FYSETC S6 I’ve tried to do the same. It doesn’t work, is my configuration to blame? The Sensor I’m using is an A3144, I’ve tried w

I noticed the 5v switching regulator used for the maxPCB4 are not available through SMT partner to EasyEDA. Is there a shortage of these things? Anyone has a suggestion where to buy and not wait 6 wee

Hi all, I have a silly question regarding the SHC: has anyone else had problems with the last digit of the RA/Dec seconds _not_ displaying for the above (smallest) OLED display? There are not many men

Half year ago decided to build a telescope mount controller based on the MaxSTM3 Hardware. Took a while to collect all the parts but managed to get it up & running for Axis 1 & 2 in combination with t

Hi fellow enthusiasts, First-time forum poster here -- I have followed the group since early 2021, when I decided to assemble a MaxESP3.03 PCB (ESP32-WROOM-32D dev kit, D1 mini ESP8266 wireless contro

Hi all, first post here, so be tolerant with a novice as I am, Thanks, My question: I would like to add a buzzer to MiniPCBv2 with a Teensy4.0; Pins.MiniPCB.h (is the correct one, I argue) reports #de

Hi, i need help to set the correct values for my mount. I have a synscan upgrade kit and the motor-controller is broken. Now i have a Wemos R32 board and TCM2130 Stepperdriver. The goto works, but my

The title says it all. I am using only one focuser, but it is on AXIS4. Since I don't need field rotator, what should I edit in Config.h in order to turn AXIS3 into additional focuser? Couldn't find a

Hello SmartWebServer maintainers, I have found a typo bug in the src tree for the tmc2209.cpp & tmc2209.h files. In the most recent download a few minutes ago I found the tmc2209.h file spelled as Tmc
