Hello,
It all started with the Y-Axis Stall error. With inspection I found I needed a new bearing. To make things easier in order to "drill out" the locked in screws, I removed the entire Y assembly from the machine, big mistake. All connectors on the Head Termination Electronics Board Assembly(HTEBA) were factory glued, male to female in such a way as to reveal naked pins on the HTEBA as each connection was force ably pulled out. OK, I replaced the bearings and properly assembled the unit. Regarding the connections to HTEBA, I was somewhat careless and mis-pinned the close cover/probe connector to the naked pins on the HTEBA, not knowing this, I fired up the machine and got the "please close cover" readout. Checking things out, I found my incorrect connection and fixed it, checked it and got the same error reading. Ordered a new HTEBA card, new wire assembly for cover switch/probe. Same problem. OK, so now I removed the cover and shorted out the motor cut off connection and the close cover pins on the HTEBA. Same problem...... "please close cover" The only thing I can think of is I may have trashed a logic circuit when I mis pinned the cover switch/probe connector to the HTEBA. Any ideas? Please note that I have absolutely eliminated the possibility of the HTEBA receiving a signal that the cover is open (shorted the correct (far left) pins) and additionally shorted the motor bullet connectors.
If it is the system controller assembly, is their a fix other than $300+ replacement. Note that prior to getting the close cover notification, the machine readout panel performs correctly and accepts my input. For testing purpose I've asked to measure a board, after which I get the close cover reading.
Thanks in advance for your help
Neil
