This is the first time I've heard of anyone trying to run our Wheezy/RTAI system on hardware with an ISA bus. Please post the entire output you get when you try to start linuxcnc, and the entire output of dmesg after it fails. Original Message From: Todd

[Emc-users] ISA Cards and Wheezy RTAI?

2017-12-13 Thread Todd Zuercher
Is there a problem with the version of RTAI on the Wheezy ISO which prevents it from working right on a system with an ISA card(s)? I have tried several times to install one of the newer Linuxcnc ISOs on an older system that has been running Linuxcnc on Ubuntu 10.04 for years. The Wheezy iso s

Hi Gene, It's been a long time since I've looked at the code, and I don't have it in front of me. But... 1. The file is named _clear_offset.ngc -- isn't it (you didn't leave out the .ngc)? 2. As I recall, the file is opened the first time it is referenced (and memory mapped). After

Re: [Emc-users] synchronized servo motors with phase control

2017-12-13 Thread Dave Cole
I doubt this will be an issue.  I did an application a while back (years) incrementing a position in hal for a linear drive that was actually a chain loop.  So the servo motor always ran in the same direction.    Rollover of the position counter was brought up then and calculations were made. I

Thank you John and Andy - We will be running at a max speed of 900 RPM, so will have 150kHz encoder pulses, which will certainly be too much for software encoder counting. I thought about electronic gearing, but didn't see any support for that in the hostmot2 components. I'll start out with the s

The lights do not turn on the switch port that your Ethercat device is plugged into? Did you install TwinCat 2 or TwinCat 3.   I have TwinCat 3 loaded on a laptop here. Check this out.  This is for TwinCat2 https://infosys.beckhoff.com/english.php?content=../content/1033/tcsystemmanager/refer

One thing to be aware of: If your application runs the motors in the same direction for long periods of time, absolute position will keep increasing even though relative position doesn't change. If HAL still uses single precision (32bit) floats, you eventually might start losing resolution. I
