Well ok then.
Is there a particular website where I can start reading up on this stuff? I have think I have a half decent grip of the parts inside the box but I have no real understanding on their interactions. I have no idea how to determine what should be connected to what pin and how that translates to inside mach3 when you look at ports and pins. I didn't build this machine but I don't mind getting my hands dirty with it.
It seems to me like if it used to work fine it should not be too far off and unless there are differences in the 7762 ports and pins to the 7761 ports and pins, this should all be software related. While I really do appreciate the help from both Vital and MachMotion, confirming that the 7762 is talking to the computer does not solve my problem. I don't mind learning but I need material for that. If anyone else has some ideas and advice I would love to hear it. Marc I am also willing to pay you for support or anyone that can help me with this.
Here is a list of know facts;
-This machine was built by someone else. It worked ok for the last two years with the 7761, 7535 (not v3), 7721p. It uses and dell with XP, Mach3 with 2.********* revision and Ultimate Screen. It uses dc brushed servo motors and motion dynamic cards
-I took out the 7761s and directly replaced with a 7762s. Plugged in everything to where it was plugged in before.
-As soon as the install was done I ran the VSI device manager and upgraded both the firmware from 7.********* and the fpga file to current files. Based on the file I read I disabled the J11 & J12 Stepgen and Encoder Variables in VSI Manager. All the firmware pins have -1 value in VSI Manager as well
-I also upgraded the mach3 driver
-When the mach3 was loaded up the machine would only arm momentarily. The z and x axis moved when it armed for that split second. the only error message was "command killed due to buffer error" When I had the e stop in it would not try to arm at all which I thought was a good thing. on the pins window in Mach3 the emergency led light was flashing red and all the limit switches were yellow
-Marc remotely accessed the machine and verified that the 7762 is in communication with the computer. Nothing changed after a new XML file was loaded by Marc.
-MachMotion went remotely on line and changed the value of the input pins on the e-stop and limit switches from low active to high active and at that point the machine was able to arm but again z axis and x axis were in motion. and after about 3 seconds I had an error message that said" buffer overrun". When you click ok Mach3 just shuts down.
- I went back in just to see what would happen if I only changed the low active value for the e-stop and not the limit switches. The machine armed but disarmed right away saying limit switches are triggered which is obviously not true.
Where do i go from here?
