“What you quote is correct. What did you expect? Think of hitting a limit switch as a fatal, non-recoverable error.”
While your reply was technically correct for general operation, it isn’t for homing and it wasn’t exactly the kind of help we would expect from a mod, nor was it any sort of help to a novice stuck on a problem.
I understood perfectly what his problem was and how to fix it, what you did was to confuse and be a bit pedantic.
Switches are switches and can be used both as limit and homing switches, depending on mode of operation. If you’re not aware of that, you might want to reconsider your role as an expert. It was bloody clear from his post what he was trying to do, yet you talked down to him and actually pointed him in the least helpful direction you could.
Many questions are asked on here that I don’t respond to, feeling there are more experienced members able to better answer them, working on the premise that if I can’t give an informed answer that helps, wait and see if someone else can.
Maybe you should think about what value you are adding before you post?
You need to set them as homing and limit, as the wiki article states:
https://github.com/synthetos/TinyG/wiki/Homing-and-Limits-Description-and-Operation
The following switch settings are supported:
0=Disabled – Switch closures will have no effect. All unused switch pins must be set to Disabled.
1=Homing-only – Switch is active during homing but has no effect otherwise
2=Limits-only – Switch is not active in homing but will act as a kill switch during normal operation.
3=Homing-and-limits – Switch is active during homing and acts as kill switch during normal operation.
The following settings are used for switch configuration.Humming would indicate a lack of current. The range of motion of the adjuster is from approx 8 o’clock to 4 o’clock, so around 270degrees. You shouldn’t need to turn further than 1-2 o’clock to get things moving. If you have turned it past 4 o’clock, there’s a reasonable chance you’ve broken your adjuster.
Did you use a voltmeter to confirm? . Did you follow this document? https://github.com/synthetos/TinyG/wiki/TinyG-Tuning
It very much depends on the PSU as to whether it will accept operating in series or parallel.
Some will work in parallel, some won’t – the same that won’t will work in series, the ones that did work in parallel won’t work in series – some will work in both and some will work in neither.
It depends 🙂
One thing that is sure, for it to work it MUST be wired like this:
I’ve used a Super-PID before – great unit. I asked the same question of the manufacturer way back when.
The instructions are clear: “Super-PID can directly accept a speed control voltage of 0v to 5v ”
So, it can directly accept between 0 and 5V – 3.3V is between 0 and 5V.
You won’t have a problem.
