stiickies?
I have a working config using 2 parallel ports. Can I start with that?
I am using closed loop steppers.
I undestand that I will have to add invert pins etc.
The reset pin has me confused. Is it to generate a particular pulse width?

I just watched your YouTube video on you high speed ohmic and it’s impressive. 

I assume you mean this one

I had a job which I filled a 8' x 4' sheet with some flanges and small parts. I cut it in 3 sections on a 4' x 4' table and there were heaps of probing so over time I tweaked the probing routine heights etc. I was using my hypersensing which uses a THCAD for the ohmic sensing. it does not like Hypertherm machines on a water table but it would work for you by the look.

Part of the speed comes from the way it breaks contact on up travel because as soon as it senses a fall in voltage, probing finishes (before the contact is broken).
I've been sent a ohmic circuit from Proma Elextronika in Poland. Its a very nice piece of kit and have some very good reviews on it. This will by my water table solution.

The documentation is outdated, try clicking on the colored channel buttons on the bottom of the screen to toggle channels on/off. Eg the red button with '1' on it.

    Hello, I have a machine with 32gb of RAM and an i5, QTdragon fails to visualize gcode files over 20-30mb. The RAM is not even loaded. What could be the problem and how to solve it? Instead of a program, a box within machine bounds is displayed.
