The problem is with the configuration of the network environment.
1. Turn off DHCP in the configuration utility.
if not help:
2. connect UC controller directly to the Ethernet port on the CNC PC motherboard and start UCCNC.
if not help:
3. Check - in Task Manager - some time UCCNC is not closed properly and halting in the tasks. Close halted UCCNC task.
Thank you. Unfortunately, this is not suitable for me.
1. I already use fixed IP addresses for the UC300ETH and the ETH to RS485 converter.
2. Can't do that and it should not be necessary. I want to go through the switch so that I can use more than one PC (not at the same time of course) and also not interested in having three Ethernet cards in my PC. Would not be a very nice solution.
3. When the PC is just started it is definitely not running. Also, uninstalling and installing again and again creates the same problem. Never the less, I will have a look next time and see if killing it manually is necessary or if that would solve the problem.
Anyway, when I start 1.2049 it updates the firmware and starts without issues in exactly the same environment.
