Well there is another thread dealing with the admin side so keep the chatter here :) Yes Rtelligent have both open loop ECR series and closed loop ECT series drives. Dominik's CIA402 component is effective here. The ECT series seems quite solid, Their NEMA24 motor offers amazing performance based on our stepper motor model but I have not tried one for real. It should keep up with small Nema 34's
Intelligent also have the ECR1616 I/O slave and its working well for me. Rtelligent's products are very well documented in English There are a number of other Chinese I/O modules available. I have one with an Encoder input coming. Wish me luck! I was unable to get Sittner's repo working on Debian 11 (Bullseye) but it was flawless on Debian 10. I think it was a Etherlabmaster issue. I was able to install Etherlabmaster on Bullseye using a .deb file another member provided. This bypassed the need for Stttner's repo. So there is a little bit of work to get this operational on Debian 11/12/unstable Rod Webster *1300 896 832* +61 435 765 611 Vehicle Modifications Network www.vehiclemods.net.au On Tue, 1 Mar 2022 at 11:29, Chad Woitas <cwoi...@rmd-engineering.com> wrote: > Well, this is already off topic: > > For the hobbyists: These seem promising > http://www.rtelligent.net/ECR60.html > > > For the Commerical Applications: > Sittners repo works well with Bosch/Beckhoff/SMC, there hasn't been any > updates in almost a year but a few MR's are up. > > Beckhoff will recommend a PLC/Safety PLC control talking to linuxcnc > through a bridge. > This seems to works albeit a 15-20 ms latency from command to movement. > > > Exploring a few other options as well for Ethercat. > > > ________________________________ > From: Bernt Hustad Hembre <bernthustadhem...@gmail.com> > Sent: February 28, 2022 2:40 PM > To: EMC developers <emc-developers@lists.sourceforge.net> > Subject: Re: [Emc-developers] LinuxCNC is in Debian! > > Hi all, > > I have not used EtherCAT equipment with LinuxCNC.
