Re: [Emc-users] Released: EMC 2.2.2

I am in proccess of configuring a new machine with 2.2.1 and, after reading your email, I ran Synaptic reloaded the list and it does not show 2.2.2 as the latest version. Maybe it takes a while for the repository to update? I am having trouble getting homing to work in 2.2.1 and I am hopeful t

[Emc-users] Released: EMC 2.2.2

I'm pleased to announce the next bugfix release of the EMC 2.2 series, version 2.2.2. This version fixes many user-reported problems. The new packages are now available in the package repository. If you already installed 2.2.0 or 2.2.1, this is available as an update. If you are still using 2.1

Re: [Emc-users] G Code Generators

I've uploaded a new version of face.py to EMC Wiki with many new features some of the suggestions from Manfredi have been incorprated as well as some I thought it needed as well as the fix for the remainder undocumented feature that Tom found... Please let me know if you see any problems or are

Re: [Emc-users] Encoder for lathe spindle

I just found this link: http://members.shaw.ca/swstuff/spindle-encoder.html I may have to try this on my lathe. I am concerned about coolant getting into my current setup because there are no seals between the spindle shaft and encoder housing. I am not wild about the belt either. With my current

Re: [Emc-users] open loop galvanometer control

A microcontroller will definitely give you better response (EMC is to slow to really scan the laser-machine tools are moving about an order of magnitude slower than a laser scan), but you would have to code the graphics or find a way to convert them. Easy enough for simple graphics like a squar
