Gregors,
As far as we see, your PLCM Mach3 version is not actual.
Please find the updated one here https://purelogic.ru/data/soft/elekt...mach3_soft.zip
Also having a PLCM-E4 motion controller, you have an opportunity to get Pumotix software free.
Please have a look at the thread http://www.mycncuk.com/threads/13399...x-CNC-software
