i have been trying to upgrade to M4 for more than a year. M3 runs like it should be on an intel nuc I5 with 16GB RAM, with CS-MIO IP/s from CSLabs. on this PC i run M4 as wel.... i continuously get PID errors when moving the axis. had several times contact with CSLabs, and they updated their firmware once in 1.5 year... still get the PID errors.
i went back to M3...tired of testing. M4 in combination with CSLabs products is definitely not the right combination

thanks all for the replies.

It's long issues here csmio and mach4
If you search in there plugins you never see Mach 4
They always explain it's fit both but ( I'm talking when I search supplier then I chose Pokey's)but they never promote plug-in to mach 4

Hello, I have been working since the beginning of Mach4, I have 10 machines working in the industry, all with CSMIO/IP-A. and the question is? You have problems with the PID system. If I remember correctly, Your Controller is CSMIO/IP-S, and this System does not use PID.

hi, the cslabs ip/s gives a PID error message when the controller receives more pulse information than it can handle. it has nothing to do with a PID control loop.
