I have been using EC300 with Remora for the last four months, and it has been great. Once I got it up and running, I didn't have any problems. You can now get an EC300 with Remora firmware on eBay.

I noticed when looking at encoderS0.position I'm getting no valves. Also no valves when looking at spindle.0.revs in halshow. Could this be causing the issue ? EncoderS0.phase-Z is getting the signal from one of the remora input pins(my encoder index) which both are blinking in halshow when triggered. Should I be seeing the spindle.0.revs displaying a valve in halshow?

normally yes, it will increase, and then during threading i think, there is a reset index command which turns it to 0 i think. during css operation im not sure.

did you end up getting the abz encoder? did you do the spindle.speed-in stuff? monitor that while your doing the css and see if it takes a dive while the speed is changing. the remora.sp0 signal looks exactly as i would expect though, with the speed tapering up or down as the diameter changes.

Yes iv A and B hooked up to the PV which is working, counting fwd and back. Iv another encoder that came with the machine stock (emco encoder) that I'm using for the Z as it's 24v and hooked straight to an input pin. Yes iv the spindle speed in , in my Hal file same as yours.

When I hook a multimeter up to the vfd 10v in, the voltage physically drops near to Zero if a lot of speed adjustments are done. So I can see now what is happening but iv no idea why the voltage drops so much. It must be something to do with how remora outputs the signal ? 

I spent the whole day going through different code with chatgpt and still nothing, it's still dipping. Should I ask this in a general new topic in the forum or is this specific to remora do you think

thanks vp, that will save us a lot of work. we need to archive this shit for the repo or something

darkpheonix - that is good to hear

spyder - this is my WIP remora spindle template (no encoder edition). murphy is also using it. some might be duplicate to what you have now
Code:

I tried this spindle config and I get the following error - ./remora-ec500.hal:79: Ini variable '[SPINDLE_0]RPM_GAIN' not found. Would you or anyone else know what might be wrong and how to fix it?
