Wiring a Corner finder and height control

[EddyCurrent]

just reading your linksilyavski, is the resistor needed in my application?

No, it says this in the uniport manual;

"Either way you can wire switches between input and ground with no external component needed."

you know, i keep forgetting to read that damn manual! guess i just like testing you guys haha

Uniport works fine straight from the inputs I used one for 2yrs until it gave up the ghost. My famous Rupert Egg touch probe video was using the uniport.

OK guys i got the touch probe working (ish)

The bit touches the ali plate - stops and backs off
comes down again slower - stops

but rather than reset above it drives the tool down!!

for the purpose of the video - "PLEASE NOTE: No innocent tools were hurt in the making of this video. collet is loose and the tool is wounded volunteer" the thud at the end is the escape key being pressed.

Presume your using gerry's screen set.?

Have you set the clearence plane.? and is the number positive not negative.?

With all the issues you have been having with changing axis directions etc could you possible have the Z axis going in wrong direction.? IE down = positive Z axis are nearly always negative moves down with positive up.!

Test by zeroing dro clear of any obstructions and typing G1 Z-5 F100 in the MDI box. This will move nice an slow 5mm down. If goes up your set wrong.!

Cheers JAZZ,

yeah im using said screenset.

I done G1 Z-5 F100 and the axis goes down 5mm

Clearance is +5.000

still driving intop the plate

went into the simple zero file does this make sense?

Else ' Off = Metric Measure MM

FirstProbeDist = 150.0 ' Probe down 150mm
FirstRetractDist = 1.0 ' Then retract 1mm
SecProbeDist = 6.0 ' Then probe down 6mm
FirstProbeFeed = 250.0 ' First probe feed @ 250 mm/min
SecondProbeFeed = 25.0 ' Second probe feed @ 25 mm/min
ClearAllow = 2.0 ' Max Allowable Clearance = Z Machine Zero - 2mm



i cant read that lol
