PS. Thanks for your contributions that became MB2HAL. I'm using it. ----- Original Message ----- From: "Les Newell" <les.new...@fastmail.co.uk> To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Sent: Wednesday, June 28, 2017 2:26:52 PM Subject: Re: [Emc-users] Rough motion with servos
Hi Todd, I am building from source. I have tried several distros: Debian - something old, I can't remember what. This has been running fine for about 8 years but it lacks driver support for modern hardware. Ubuntu 10.04 LinuxCNC ISO - appears to run smoothly but I can't test properly until I get LCNC to build. It's also a bit long in the tooth. Ubuntu 16.04 LinuxCNC ISO - runs rough but I can build fine. I've tried various different branches of LinuxCNC, including one that is close to what I was originally running, on this and they all run rough. > Are you sure all of your custom modules are still "custom", or needed?

Yes, some of the modules do have fairly direct replacements, such as my original Modbus component and the new MB2HAl (which is based on my original). However I have extra stuff to control my spindle and electronically controlled gearbox which don't have direct replacements. > Maybe they can be added using halcompile (formerly known as comp)? Yes, most are comps but I still need a working build environment. I am wondering if now would be a good time to move away from RTAI and use preempt-rt instead. My reasoning behind that is that I have two projects coming up that use HM2 ethernet boards so I'll have to work with preempt-rt at some point. Keeping everything on the same platform will simplify maintenance in the future.
