Are you using steppers with no feedback?

Iv gotten my homing switches as limit switches and works ok. But the lathe also has a prox sensor which would be much more accurate. I have added the following lines to the ini and Hal. It finds the limit switch and then goes looking for the prox. The prox triggers and it also triggers in hal but it dosnt trigger as home and keeps searching till it bottoms out. Any ideas? I'm on Linux 2.10
The prox by the way is a pulse from the encoder, triggers every full turn of the stepper. Pulse is on input.07

Thanks for the link Scott,got it working. Thats the homing/limits, axis and spindle working. On to the tool turret now. also is there an encoder in remora fast enough for a spindle ?

Great to hear! On the RT1052 boards the software encoder module is the only one available at the moment. Hardware encoder counting is on the to do list.

Hey guys what do you think I can do to recover this EC500 board? I’ve got no ack if I use daplink or esp board with wifi dap no matter what I do this happened after I flashed and debugged it than after that it was working and I restarted it and now no activity in the Ethernet or dap, solid two red lights. How can I recover this?

A couple of things to try

1. Turn the power onto the board whilst trying to connect
2. Jumper the BOOT pin and 3.3v and then turn on the board, try to connect.

On the EC300 there is a boot button which on occasion I've had to use to change the boot mode to allow a connection. Haven't had the issue with the EC500 though.
