I am able to communicate to my Davinci 1.0 w/ Repetier firmware but only for a few moments and then it just stops working. The communication is intermittent. I have the baud rate set to 115200 both in the EEPROM and in Simplify3D. Repetier-Host can communicate without issue.
Under Firmware Configuration, I have:
Select Profile set to RepRap
All G/M codes are the same as they were in Repetier Host
Wait for startup command UNCHECKED
Serial Acknowledge OK
Comment Character ;
Allow command buffering CHECKED and 202 bytes (same as I have in Repetier Host)
Communication Timeout CHECKED and 5 seconds.
In Machine Control Panel, I select the correct COM port, set the baud rate, have verbose checked. When I click connect, it says attempting connection followed by connected to machine. Everything seems to work! I send some commands, it responds. I do some G28s and some G0s and turn on and off the bed and extruder and then suddenly it doesnt respond to any commands anymore. If I disconnect and reconnect, it does the same behavior. I also don't get a temperature back when it auto sends M105.
I have tried a few different USB ports and that doesn't matter.
I have reflashed Repetier and that too doesn't matter.
Any ideas?
