Received the new PICA card yesterday and immediately installed it. Confirmed that ALL connections were correct, that the board was properly seated on the MEGA, and that the stepper drivers were positioned correctly. Great expectations that after power on, I would have a functioning printer. NOT! When powered on, the LCD display was not properly displaying the upper left quadrant of the display:
Being the eternal optimist I thought I could overcome this nuisance and proceeded to attempt to run AUTO HOME. Nothing happened when selected. Not good. I then attempted to move the X, Y, and Z axis positions (Prepare > Motion …). Nothing moved. I verified that the X,Y, and Z endstop switches were working – they were. I then attached the printer to its USB port on my PC. I didn’t get the message that should display when connected to the PC so, it isn’t communicating with the PC.
Any suggestions on what the next steps should be? Any other things to check
with power on before I remove the board?
(I would note that the PRINTER FAN connection on the new PICA is a JST-type connecter instead of the two position male header pins on the older PICA. Fortunately I am able to use the existing two-position female connector but am not sure if the polarity is correct. I assumed the + lead would be to the right?)
