AFAIK/Sounds like the issue where GPIO12 (the stepper drivers enable pin) needs to be pulled low with a say 4.7K resistor. GPIO12 controls the flash memory voltage at boot must be low.

SERIAL_C_BAUD_DEFAULT is OFF , this needs to be ON to be able to connect via OnStep Android app and bluetooth. how are you testing your OnStep ?by serial command?

Design of your mount? How are you getting 720:1? How many stages? IIRC A4988s are limited to 16 µsteps. A GR1 of 5 and a 144T worm wheel is 720:1. Stepper-Steps MICROSTEPS GR1 (Other stages) GR2 (Fina

The file name first char is supposed to be upper case. Should be fixed now.

#tmc2209 #sws

Should work for Axis1/2 AFAIK... Both drivers must be in the same micro-step mode and no micro-step mode switching is allowed; the spread pin on the drivers should be supported though.

With some modifications, in UART mode, they should. You will have to unsolder some pins off the drivers and solder them back pointing upwards so you can connect them to MCU.

#tmc2209

Yes, hardware is using jumpers to configure the driver. The MiniPCB2.0 only supports software configuration thru SPI.

Was hoping to use my gps module with my tmc2209's but just read that it's not possible. Is there any way around this at all? I know it's a redundant question but I've already purchased the module so j

Even having inserted the jumper in MS3, which should have enabled the spreadcycle mode, the motors stall over 0.8deg / s. I don't know, then, what could be the cause, but I think I'll be satisfied eve

I have had my CG5/EQ5 converted to Onstep for some time now, but the horrible Texas heat and mosquitoes (along with too much summer clouds) prevented me from fully testing the Goto and tracking. With

Otto, Thanks for sharing. Your conversion is in the showcase now. Yes, we need a table somewhere on what specific x driver goes with y board, as it is not obvious. In the meantime, users can either lo

At the end of the day I (as you have) use the TMC5160 as my goto driver. It can be completely setup from the config.h file and offers a current range that supports most of the stepper motors we use. I

Excellent ... Both should work. Both are well tested. If you have an Android device, the WiFi will give you a very useful application for most OnStep functions.

The Arduino Nano does not work with OnStep. You need to get a supported board. Before you decide on which one, read the OnStep Wiki, specially the last question in this FAQ. The resolution needs to be

#tmc2209 #arduinonano

As Howard said, OnStep cannot use the UART interface. You can still use the TMC2209, but you are limited to microstepping of: 64,32,16,or 8. Not a real limitation though, since it covers the range we
