Hello everyone,
I am new to this community and new with cnc as-well. I have experience building a 3D printer and tweaking its firmware and programing some scripts to generate and clean up 3D meshes but a cnc seems to be much more complex. I bought a 2KW spindle with a VFC, nemas23, stop buttons and a cheap generic 5 axis breakout board with optocoupler isolation that connects directly to the montherboard of the computer via a passive parallel port adapter.
I still have no idea about how most of this stuff works but I hope it will not be an odyssey. Do you have any suggestions on how to start? Sort of like the "hello world" in programing.
Thank you and regards

An immediate following error may also be because the feedback is backwards.
(if the encoder is scaled right and has the correct direction, you may need to
reverse the analog output polarity in the hal file)

I just checked and they are in the left hand position.... I'm going to swap them over and give it a try!! Thank you as always for your help.

The 4th jerks when I enable the machine and i get a following error. The only way I can get it to work is if I enter a crazy high pulse count. It will rotate but with terrible accuracy, like 1 revolution shows a couple of degrees of rotation.

You can use single ended (5 wire) encoders with the 7I97/7I97T
as long as the three 7I97/7I97T encoder jumpers for the single ended
encoder are in the single ended/TTL positions (right hand position)

What error do you get?

Good morning gents!! 
I was wondering if a cheap amazon Incremental rotary encoder (5 wire including ground/shield) could be used for a 4th axis? I am using a Mesa 7i97T board and am experiencing so difficulty with it. I can see it count in Hal show but when i try to use it in real time it keeps erroring out...
Once again thank you to all the experts that make this possible!!!

please add your json config, i take a look

okok, can reproduce it: ERROR  (CT2000) : "/mnt/data2/src/riocore/Output/Tangbob/Gateware/fpga0/pins.cst":69 | 'syntax error' near token 'mbus0'

Hi,I am trying to add a 16DI/16DO Modbus RTU module (N4D3E16) via an RS-485 transceiver on the tangnano9k on RioCore.When running fpga compilation, Verilog synthesis fails in Gowin EDA with the following error:

here is web based interface

wow, very nice !!!
is there a repository for the web gui ?

If it all runs smoothly, it might even be worth building a separate board for it – after all, you wouldn’t need an extra PC for it anymore.
