Changing TMC2660 into TMC2130

Stan

@dc42 @briskspirit there is neither a laser engraved model number or a sticker... I have just mailed the company for mor details. If i can't get more info from them i'll try the method of measuring the length and resistance. Thank you all for your quick responses!

Stan

@dc42 okay measured the phase resistance at 1.8ohms, think that means between 1.5 and 2A? And found out i have 2 Y motors.. guess i overlooked one. So in short: 6x bipolar stepper motors with a current draw between 1.5 and 2 amps. Hope this helps you and me out? Thanks again man!

It looks like those motors would be a good match for the TMC2660.

@dc42 and what about the secondary Y-motor? Just wire it in with the other one but switch out two wires?

Three possibilities:

Wire the two Y motors in series. That way they get the same current. If you have only one Z motor, then the simplest way to achieve this would be to connect the Y motors to the two Z outputs, and the Z motor to the Y output. Then use the M584 command in config.g to swap Z and Y.
Wire them in parallel, and double the Y motor current in the M906 command in config.g.
If you have only one extruder then the E1 motor output will be free. So you can connect one motor to the Y output, and the other to the E1 output, and use the M584 command in config.g to tell the firmware you have done that.

If you are using 24V power then series connection should work well. If you are using 12V power then I suggest one of the other two options.

@dc42 okay thanks a whole lot again man! Did not see there were 2 Z connectors... Decided to go with the duet ethernet. Then i'll try to change the Z and Y then in the slicer. I'll order soon!
