dear Nicklas, the problem you mentioned with cookies for accessing the OpenCN forum https://discourse.heig-vd.ch/c/opencn seems to be resolved.
best regards, Raoul -----Message d'origine----- De : N <[email protected]> Envoyé : mercredi 13 mai 2020 22:22 À : Herzog Raoul <[email protected]> Objet : Re: [Emc-developers] OpenCN forum + announcement of release v2 I tried to register on the forum but failed, it made complaint about cookies but do not think this an issue because it works everyhere also then asked if cookies are OK. Usually there are discussions of software steppers and statistical measurement of latency. This however look like they now what they are doing: 4) remote GUI in order to eliminate intermittent jitter problems in EtherCAT @10 kHz due to DMA access of GPU Have two different size Ethercat inverter card there I am soldering on prototype board right now. Have already tested first prototype boards and they should exactly what is needed for CNC machine servo drives but nothing special. Would probably make sense to make them available under GNU license, then I could probably get some help with control algorithms for different motors while others would benifit from them.
