Hi,

Thanks for your response I got my readings all from the soldered pins on the back of the board, as it worked fine with the main power connector for the board.

I will test your suggestion and get back to you asap It feels good to get closer to the root of the problem!

Thanks.

Also when you said to check the tension, did you mean something to do with the resistance?

thanks.

Hi :)

I have tested pins on the mainboard and got some readings:

Power Supply cable: 12V
USB board connection: 2.04V
Extruder heater: 0.02V
Heatbed heater: 0.02V
Thermistors: 4.97V

I also noticed a red flashing LED on the extruder heater (which doesn't stop flashing during print) once it had ...

Hi,

Is there a schematic available for the GT2560 Rev A+ that I can use as a guide? Otherwise I am basically just guessing which parts to test specifically on the board (other than that obvious connections)

Thanks.

Hi,

Thanks for all the info, I'll figure out what I'm doing and report back my board is the rev A+

Cheers

Hi,

I have looked at the cable ends for the psu and they look fine, I have attached some pictures as well. I also have a multimeter but am unsure what to test and how to use it. Can you please help?

Thanks

Hi,

I was going to buy a multimeter anyway so no worries. The board is a GT2560; I will take pictures of the controller and connections soon and upload them

Hi,

I willcheck the quality and buy a multimeter to test the PSU. Thank you for the suggestion and I will get back to you

Thanks.

Hi,

I have ran some more tests and found that the 'gibberish' text and communication issues always occur after the heatbed has finished heating. I tried connecting and doing basic functions without the power being on and I had no weird text or error messages. Assuming it is the power supply, what ...

Thank you for replying so quickly!

Could this also explain why is cuts out after a while even when being able to print? The same thing occured when using an SD card, so it didn't seem like a communication issue at all. Could the power supply also cause the 'gibberish' text?

Thank you for your ...
