Thank you for your reply, I have read your explanation before.
According to your explanation, I changed my scale to
Only in this way can my movement axis be stable, but when I issue an instruction to move 1mm, the actual movement is not 1mm but about 6mm.
I use AKD drives and linear motors. I don't know what kind of algorithm should be used to calculate the scale to fully adapt linuxcnc to my machine tool. I want the instruction to move 1mm to make the motor actually move 1mm.
Looking forward to your reply, I want to know what this algorithm looks like, rather than simply changing a certain value.
According to your explanation, I changed my scale to
<pdoEntry idx="607A" subIdx="00" bitLen="32" halPin="poscommand" halType="float" scale="-1000000"/>
<pdoEntry idx="6064" subIdx ="00" bitLen="32" halPin="pos" halType="float" scale="-0.000001"/>Only in this way can my movement axis be stable, but when I issue an instruction to move 1mm, the actual movement is not 1mm but about 6mm.
