I have posted on this issue last month in another thread and after a lot of diagnosing I came to the conclusion that my problem is the breakout board. I bought the machine in 2010 and EzRouter has said that the "Red" breakout board is no longer available. They wanted to sell an upgrade but I just don't have the extra $1400.00 to spend.
The back story is, I have checked parallel port power at the pc, male to male db-25 cable and ribbon cable that is inside the control box that plugs into the breakout board. Pins 10,11,12,13 and 15 show 4.38 DCV. Pins 1,14,16,17 show 64.3 DCV. I have checked the proximity sensors where the cables connect at the board and the cable connection at were the sensors are mounted on the machine and show 23.85 DCV. When I covered the sensors with metal at X,Y, or Z one at a time and the light at the sensor goes off and on the diagnostics screen the Home and Limits lighted up. But on the A Home, there was no change. Light still on on screen. ( During the testing, I set the pin for the Estop to "0" so it would not interfere with the diagnosis phase.)
On the Mach3 Diagnostic screen I have the Emergency light flashing red and the A Home light is yellow. During the testing I changed the low active box in inputs screen from "x" to "a check mark" for the estop on pin 10 and A Home on pin 15. They both turned off but still not able to home machine. (When I did try to home the machine the Z axis on the main screen started moving, but no movement at the machine.)As another test I changed the low active box in inputs for X-- Limit and X Home to a "check mark" and the yellow lights next to each on the diagnostics screen lighted up, at sensor, light went out. Did this also with Y and Z axis. Same result.
So, as I stated above. I believe that the board is bad. My question is: Will the board shown in the link below work with my machine?
Cnc Breakout Board, CM-201
In conclusion, if anybody knows what I might can try other than changing out the board or if you might feel there might be some other solution, please advise.
Thanks
P.S. EzRouter used "no brand" drives marked "SD 1000 and the motors "SM 1000". The main power coming into the control box is 240 ACV and there is a 240ACV/24DCV transformer inside the control box that powers the breakout board and the drive for the spindle.
