As always a brilliant and great documented tutorial. I'm wondering, if you knows a port of the arduino servo lib for ESP32? I did some examples with ledcSetup, ledcAttachPin and ledcWrite. And I want to do this within multitasks. Hope you have any hints for me. Thanks
Thanks. What I learn - be careful by calibrating the tmc2100 steppermodules with a metal screwdriver. The pot is very close to the power pin. And after inspecting the mess don't insert them in reverse. Two major human faults - hope others can avoid my mistakes.
The steppers sound pretty loud in the recording - are they as bad in person? Is that inherent and unavoidable, or can it be reduced? (I was thinking of using steppers in some Halloween props, and this much sound would be problematic).
The noiselevel with 32x microstepping is OK but not really quite. This is why I try the TMC2100 with 256x microstepping. But unfortunately mine blow up while calibrating the output current and touching also the unlimited VCC input pin. With very slow speed they sound more like the ticking of a wallclock. But this can also vary with the vendor. Mine are (maybe) the cheapest NEMA17 in this size/torque for about 8$ delivered.
The sound is only because they are on his table. The table reflects the noise and makes it much much louder. If you hold the motors on your hand you can hear near nothing.
Sorry I am a little cheap so even I have to wait some weeks I am buying from the cheapest seller only if the ranking is bad I am a little sceptical, so I am not prefer any seller for modules only if I do some high quality stuff I order from the big component sellers direct.
Have to use this setup because this board (github.com/pcbreflux/espressif/tree/master/esp32/kicad/ESP32-adapter) have no usb2uart bridge and no 3.3V voltage regulator. If you use a devboard you don't need this. But my other devboards are either used in a different projects or sacrifice to the espressif heaven or in the mail.
While tuning the screw for the resistor value (current regulation) with a metal screwdriver touched the pin thats 1mm away that destroy both boards. Now i would suggest to use a ceramic screwdriver.
pcbreflux So sad I only demaged A4988 drivers but because their poor quality. I only change currents with metal screwdrivers when powering it off. So now I am dealing with the new TMC2130 I recommend you to try because the SPI interface has all digital kind of things like auto current profiles, and "endstopless" feature with loose step detection feedback. It is awesome and there is easy arduino libraries. Not to mention they have internal 256 microstepping resolution and they are completely quiet
Nice video, I learn something new with each video I watch. I noticed today that using two breadboards is an effective way to use proto boards that have pins too far apart to use a standard breadboard. Does anyone make non-standard breadboards for wider proto boards?
From a pricepoint it make maybe sence to buy an smaler devboard or design your own? But for me the cheapest way today are two breadboards (one power rail cutted).

Creative video, well done, thank you for sharing it with us :)
Thank you very much for this helpful video!
Thanks for the video. Maybe the trimmer should be replaced by a proper multi-turn pot for an easy and accurate adjustment :\
Great work, !!!!, thank you.

my sincere condolences on your loss ;-)

Another cool video. Thanks.
Love the video, as always! :)
24V=IR...so...it would be either be current or dissipated as heat.

Thanks a lot for this example of Multitasking with FreeRTOS. So I have to order motor drivers and Motors (from Pollin?).

Very Informative Great Video Thank You..
in the starting on the usb hub is it a stlink connected with a usb to serial converter?
Have to use this setup because this board (github.com/pcbreflux/espressif/tree/master/esp32/kicad/ESP32-adapter) have no usb2uart bridge and no 3.3V voltage regulator.

Excellent!!! thanks again!!
have you implemented Modbus rs485 using esp32?..Got any videos for that
No, looks like a SPS/PLC ?
pcbreflux sort of like a PLC. Actually I am trying to read values from an energy meter. Could you come up with something using rs485
Thanks for the great videos
Nice video! Why " RIP ESP32 and TMC2100" on description?

Hi you have some discount code for analoglamb?
No, no codes available. Have also pay full prices for my orders.
great I like giveaways.
nice video bro
Hört sich irgendwie deutsch an
