I try to Use UART on my new MKS Gen2.1 Board:

Hey guys.

I got the artillery Sidewinder x1 and Upgraded it with an MKS gen L 2.1 Board.

I tried to use my new TMC2208 stepper driver in UART mode but its not working for any reason. hope you can help me.

If I try to run TMC_dump code my output is this:

"TMC_Dump code"

these are my stepper driver : TMC2208 Driver

I hope you can help me. I appreciate any hint

[linuxpaul]

I’m running my DIY MMU with this board and I’m also using UART and I’m not familiar with mainsail.
From my point of view, PG and PK are not valid pin names for this arduino.
Here an example of one of my stepper (mult mcu config)

[zyrron]

i got the pinning from this side mks gen l 2.1 git

[linuxpaul]

OK, checked this, maybe the difference depends to the older klipper version, which I’m using, sorry.

[linuxpaul]

… I’m running a single wire uart, not the rx/tx solution with Y cable and resistor.
I can remember I started with something like that, but it don’t know when and ahy I changed that…

[Sineos]

@zyrron

MKS Gen L 2.1

This board likely follows the RAMPS 1.4 pin layout, but it seems your pins are correctly set up. Otherwise, the error message would be different.

Make sure the jumpers on the board are correctly configured: Drivers_MKS_TMC2225_2208 · makerbase-mks/MKS-GEN_L Wiki · GitHub

[zyrron]

thats what i did i placed it on the right slot

is it possible that my drivers are incompatible for this board in uart mode?

[Sineos]

Looks correct but I do not know the board in detail.

@zyrron

is it possible that my drivers are incompatible for this board in uart mode?

Yes. On very ancient drivers this was even common, but today it should no longer be the case.
Depending on the driver it might look something like this:

You would need to manually solder the correct bridges. As shown in the picture, usually on the bottom side, roughly in the middle

[zyrron]

I put them in my request, there is my amazon link what type i boought. I am not sure if this is necessary

[Sineos]

Unfortunately, the pictures there do not show this side of the driver, nor does the link contain any related instructions.

[zyrron]

I found something in commentary section. Ty my friend. I will reply after i soldered it.

[mykepredko]

Ummm… I just noticed that the brand for these steppers is “DollaTek” and I can’t find a schematic for them.

You may be able to move the jumper (or solder the two pins as noted in the comment) and everything will be fine but I honestly think you might be better off buying a stepper module from a “known” brand (like BTT or MKS).

If you are going to try to solder them, make sure you have an iron with a needle tip and you are working with lead-free solder.

[zyrron]

those are gilent2208 v1.2 driver dollatek is only the seller name in amazon

[mykepredko]

Sorry, I can’t find a schematic for that either.

I guess my message should have been go ahead and try the modification but remember that instructions found in an Amazon review isn’t the most reliable source of information.

[zyrron]

ok guys, tmc dump gets an answer now. its working! ty!

But now i have this problem with z1. this was the same before.

Unable to read tmc uart ‘stepper_z1’ register IFCNT…

i checked the soldering it looks ok. i dont know why there is a problem now.

here are the tmc dump console outputs:

[mykepredko]

Can you post your latest klippy.log?

The most likely cause is that you haven’t set your jumpers correctly or you haven’t specified the right UART pin for the socket.

[zyrron]

yeah i understand but i double and triple checked the uart pins. but here is the photo:

and here is the klippy.log:
logs-20241216-222241.zip (104.8 KB)

[zyrron]

allright i found the issue for the last problem. 2 of the driver are broken. i resoldered it but no connection. i swapped places and tried to configure.

i guess i will replace them with 2100 tmc and standalone for z axis.

thanks for oyur help guys. this can be closed!

[mykepredko]

Congratulations and happy printing!
