I bought a used Taz 5 to learn how to 3D print. After spending a day trying to get the printer adjusted it stopped turning on. Just completely dead. Checked power supply with multimeter and it looks ok. I removed the fuses to check with a multimeter and they seem ok.
While adjusting the printer I physically moved the print head quite a bit and the LCD panel would flicker. There were also a few loud noises when the motors would run into the manual stops.
I’m wondering if the abuse I put the machine through while trying to get it adjusted wiped out the Rambo board. However, I don’t know how to test the board to see if it’s fried.
How do I test to see if the Rambo is toast? If it is toast, should I replace it with an upgraded board or get the same version?
