GT2560 rev B. Interrupt (Rx Capable) Pins?

Same question like here https://www.geeetech.com/forum/viewtopi ... 18&t=71401 , rephrased:
Which are the Rx capable pins (interrupt pins) on the GT2560 rev B control board?
And yes, I need them to figure out how to set up the UART communication for TMC2208.

GT2560 rev B. UART pins?

So, this is the board, except it has only one Molex Connector. (image taken from a different post in this forum): GT_2560_Rev b.jpg I'm trying to set up TMC2208 in UART mode. I know, I could use TMC2209... no need to tell me. The purpose of this forum post is to find out the best options available o...

2560 Rev B - how to add Heatbed Mosfet?

I'm thinking it wouldn't be the worst idea to take some stress off the board by putting an external mosfet board for the heatbed, the problem is that I couldn't figure out where to connect the triggering wire from the mosfet on the board.

Any help appreciated.

Re: Setting the Steppers current for MeCreator2 ? (A4988)

What is the value of Rs for this driver? Can't see it because of the aluminium radiator. I don't want to remove it, because i am worried it won't stick back.

What about the Z axis motor current value?

Thanks.

Setting the Steppers current for MeCreator2 ? (A4988)

Hi, My printer MeCreator2 is equipped with a variety of motors and each of them has different nominal current: The motors are as follows: X - 42SHD 0217-24F ... Current = 1.5A Y - 42SHD 0034-20B ... Current = 1.0A Z - 42HS3418-305N8 ... ??? E - N42HS3418-24B22... ??? For the Z and E motors I could n...

Re: MeCreator 2 - X Motor very hot!

I'm sorry, this is not very helpful at all... In fact you either don't understand my question, or don't care much. Either way, your latest answer make no sense whatsoever. I am sorry that I had to say this :(

Re: MeCreator 2 - X Motor very hot!

I am not sure I understand what the diagram shows ... because the red line goes in the center of the potentiometer, which normally is just a bushing (the rotation point). So, if one terminal is the GND terminal, which is the other terminal? Please check the attached image, it explains what I'm tryin...

Re: MeCreator 2 - X Motor very hot!

I understand that...but HOW MUCH to reduce it? Which voltage (between which pins that voltage has to be measured)? If i turn that potentiometer, i will not know how much I changed the voltage, unless I can measure it. The diagram says voltage should be between 0.8 - 1.2V, but it doesn't say between ...

Re: MeCreator 2 - X Motor very hot!

What value should be the voltage and between which terminals to measure? I see there are 4 wires entering in the motor.

Thanks.

MeCreator 2 - X Motor very hot!

I just noticed now whilst printing, the X-Stepper motor gets extremely hot! (I measured 56 degrees C, compared to the Y motor which was 36 degrees C) NOTE: The above is the EXTERNAL TEMPERATURE! - inside the motor casing could be considerably hotter!! Also, printer is new (less than one week) ! Inde...
