Title: uc400eth question
Post by: docltf on August 30, 2018, 06:17:35 PM

thinking about getting a uc400eth  when i update my drivers and power supply.
running mach3 .62
how is the backlash control handled ?
is it a combined mix of code and backlash like smoothstepper on direction change.
or does it handle the backlash first with each direction change then run the code.

My understanding is that the backlash comp happens during the motion. Not sure where I saw this, but I thought I just read an explanation from CNC Drive earlier this week.
You might want to ask them directly.
