It's usually easier to wire the signals commonly between the two Z-stepper drivers, or to chain the two steppers (in serial) on the output of the one Z-stepper driver.

That said, it wouldn't be hard to support two Z-stepper outputs in the code. Look for `z_step` and `z_direction` in the code. You could probably add all the needed changes...

The trick is that this device is a retractable z-probe. It has a servo control to deploy and retract the probe tip. Once deployed, it works like an end-stop. But...

@Tomin1 I did think about getting one after reading your comments, but I saw some concerns posted about reliability on the Amazon listing. At least some of them seem to...

Here's how unlevel my bed is today. This is my 3-point registration script, as manually determined with the "business card" touch probe: G29 S1 X20.000 Y20.000 Z-0.300 G29 S1 X220.000...

@Tomin1 Have you tried adding the BLTouch as a "heater" in the ConfigTool setup? This is how we normally set up PWM devices. If your device is setup as the...

I just tried it and it didn't work for me. I used DIO11, which should be PWM-able. Edit: I can see the blue pulse LED blinking on the BLTouch. Maybe...

Results: DIO11 is NOT pwm-able in Teacup because it uses Timer1 which we don't do pwm on. Maybe we can document that somewhere. Then I tried DIO6, the next set...

Continuing the BLTouch commands: The math is `pulse-width * 1024 * 256 / F_CPU` (F_CPU is 16MHz or 20MHz on AVRs) BLTouch-Classic | Available PWM Range | 16MHz CPU |...

I found a bug in my new bed-leveling code (incorrect movement after homing). Fixing it actually simplified the original change a bit, so I rebased and squashed them, then pushed...
