I have a Supermax milling machine (basically a bridgeport) running lcnc 2.9.
I use a Huanyang HY series vfd to drive the spindle motor. The mill has a varispeed.
My current configuration is here:
github.com/sliptonic/millstone/tree/linuxcnc-2.9-gmoccapy
Recently the VFD took a lightning strike and needed to be replaced. Since I'm going through that process, I thought I might like to convert it to control the VFD with modbus. That would clean up the wiring a lot.
I've installed the HY-VFD component and configured the vfd per all the instructions associated with that component, various posts, and a youtube video or two. But no dice. When I turn on on the spindle in gmoccapy, nothing happens.
My naive configuration is in a different branch:
github.com/sliptonic/millstone/tree/vfd_modbus
Any help is very much appreciated.
On another point, I've had an account on this board for over ten years and I still feel like an idiot every time I have to post. As much as I love this software, I really find it difficult to find useful information. The community is great but I ALWAYS have to post and ask a question. I never find anything useful searching and posting is no small challenge. For example consider this post. There are seven subtopic areas under 'Configuring LinuxCNC' I could only rule out two of them when trying to decide where to post. Is this 'basic configuration' or 'Advanced', or is it a 'HAL' question. Maybe I'm in the wrong area entirely. Should I be posting in the gmoccapy thread or the section about milling machines?
When I search for information, it default to only the last 12 months. Is that because older information is unreliable or is it because of indexing to make the site faster. I have no idea.
I hate the fact that my profile avatar says 'Expert Boarder' because I'm clearly still an idiot.
