New RepRap Config tool an Absolute Headache
-
Okay I will begin by listing hardware, software, and firmware data.
I am running the Duet 3 6HC mainboard, and it is running in SBC mode with a 4GB Raspberry Pi 4. I use an ethernet cable for comms and the Duet Web Control for controlling the board.
Up till now I have run config files generated by the old RRF tool with some modification. And then recently I decided I would add a poor man's BL touch, so I figured I would switch and use the new RRF tool.
Right off I started setting up the optical sensor for the poor man's bltouch and got it working, but when I went to home my X and Y it acted like the end-stops were already triggered so I tried changing the S1 in the config.g in the end-stop section to S0 but it said the S0 value is invalid so I put it back to S1 and tried rewiring my end-stops using every possible combination and no luck. So I switched out my end-stops for optical triggers and rigged up flags. That worked. Is there an explanation for the other end-stops?
Next, the servo motor I am using for the poor man's bltouch buzzes, jumps up and down and gets hot when I go to print is it just the servo motor or is it something I got wrong in setup?
Here is config.g the RRF tool v3.5.0-rc.3+2 please note that this config file is unmodified and the reason it is different in the Esteps and driver mapping is because I could set those up in the new tool but not in the old, and would have to modify them manually.

When you say servo motor you mean like an RC servo? if that`s the case you need an M42 to control it, I didn't spot one in your config, take a look at the link.

@Ignite said in New RepRap Config tool an Absolute Headache:
Is there an explanation for the other end-stops?
You need to invert the pin by adding a ! to the pin name.
https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m574-set-endstop-configuration
P"pin_name" Defines the pin name(s) that the endstop(s) for the specified axis are connected to, see Pin Names. Needed when S=1. May need ! before pin name to invert signal, or ^ to enable the pullup resistor, for example on the Duet 2 expansion header if using the pins directly without a duex5.What do you have in deployprobe.g and retractprobe.g to command the servo?
