Because no jerk ,you must put very poor acc dcc and then because very poor acc dcc ( you can see how the trapeze become longggg) CV cant calculate well and all movement become crazy
My suggestion its find the filter parameter in yours servo drive and play wirh it ,this will solve half of all problems

i wrote here in the past
mach have very good features but one very important point its missing ,its called jerk or S curve
if you use servo drive you can try add the filter time ,this in my case act like jerk and almost solve the accl problem

Mach4 General Discussion / Re: c axiss move while z axiss comand

« on: October 08, 2021, 02:49:39 AM »

change of state from minus to plus i also had ,but i think i solved it when put all motors in plus direction(uncheack the reverse cheack box)
and change direction when need only in servo drive
i have some point to agree with you (but not sure 100%)that its some thing with pokeys and mach because i didnt see such in my laptop
that its work only simulation
i saw this only when connect real pokeys card
but still i cant be sure and its big problem ,that axiss move without any command
in some cases i even get over soft max error on the axiss i didn't command ,for example when c its on "00" and its got that bug comand
in  minus ,i got c over max (c its like z "0" is max)even i didn't comand it at all
thanks
