I use easyDNC with Siemens Sinumerik 810M GA3. When executing a program using a drip feed, the machine constantly seems to stumble when moving. This only happens when blocks are actively being transferred from the computer, but if the transfer is paused and the machine is allowed to execute blocks from the buffer, then everything runs smoothly. Why is this happening? Is there something wrong with the easyDNC settings?

When you say "Stumble" do you mean that it appears to lose some data and skip a line and make a mistake? If that is the case then it maybe be buffer overflow. Make sure flow control is enabled. Maybe increase block delay see if that makes any difference.

I had this problem too. No problem when running programs in CNC memory but drip feeding was scary. In my case the machine didn't make any mistakes but the tool movements were very jerky causing the whole machine to shake. Turns out the machine wasn't anchored properly on all four legs so was rocking. So that needed fixing. But the cause was the Block Delay in easydnc was set too high so there was a slight pause between each tool movement. Decreased the block delay and all fine
