FYI, when I ran my full configuration the vfd would work correctly at startup but would fail after several commands. Sometimes after homing, sometimes after MDI commands, but seemed to lock up and stop sending commands to the VFD. No errors reported in hm2_modbus and did not recover after set/clr the modbus reset.
I looked at git repo and saw several updates after the 2.9.8 tag. I have not noticed any lockups since installing and running the RIP master. I do get a few dialog errors about PDU too small while running but I don't lose control of VFD.
