I have a GCC mercury which I bought new from the Australian supplier in 2000 and basically I have had to look after all my own problems. I am electronics minded which helps, but have very little info on the machine. It has developed the following fault.
During Power On Self Test, it comes up with the error "EEROM Malfunction Replace EEROM"
Also it does not sound the EOF alarm now, nor does it lower the table before setting the head to Home position. This can be a problem when using the rotary attachment. However the machine still accepts files and still cuts. It also allows me to lower and raise the table from the panel. (If I need to put the Rotary attachment on I have to power up the machine, Lower the table, Switch off, Fit attachment and re-power the machine.)
The other problem I have had is that the engraving level has been too high. Files that I have used many times over, now engrave deep and even through the 4mm plywood when doing (vector) text, but are skinny on the vector lines when the speed picks up. the penetration into acrylic was really bad and I had to turn the power down to 1% for engraving vector part of text (raster part seems OK)
If I try to change any parameters using the front panel it sometimes appears to change them even though it reports a EEROM error during the process.
On Power up it reports "Laserpro MERCURY", "Firmware V2.17-07", "Copyright 2002".
Then I get the EEROM error message.
"EEROM Malfunction Replace EEROM"
Is anyone able to tell me which chip the EEROM is? I am hoping it is one of the socket ones, but as some have labels over the chips I have not gone so far as to remove those that obscure the chip type. Of course this might be my next course of action, but I thought that running it past the forum might give me better information on this problem before I risk the soldering iron !
Hope you can either help me, point me in the direction of help,
Kindest regards
