Ray, doesnt your resistor do the same as a debounce setting? I was under the impression that once all the wiring was cleaned up and properly drained possibly no resistor or debounce would be needed. I am not sure why I thought/think the resistor has a time value also.

Arturo has always treated me excellent. He answers questions quickly even if I havent bought a product. When I have ordered an item, it arrived very quickly. I do understand the possible deflection of support as a frustration. I am not makng a judgement on who needs to or needed to correct a previous Mach issue.

I had that happen to a toe where it was pointed the wrong way (not in a drill press LOL) and the nurse even said first "this will hurt worse than when you injured it" the pain killers being injected directly into my toe wasnt that nice either. But when she pulled it, words dont explain the feeling. However once the pain subsided it felt much better than it did pointing the wrong way. Btw I have been keeping the medical community well rehearsed most of my life. Usually a victim of speed and gravity, motorcycles!
Well parts may fly, tools may be broken, but i got hurt once and have never fogotten it.
I was using a simple drill press, 1/2hp motor on it, 1/4" drill at say 40 rpm to drill though some wear material.
To clear the chips i was using a wooden stick, but for whatever reason i started using the kevlar gloves to move the
chips aside. The drill caught the tip of the glove on my left hand, it just started pulling and wrapping the glove around my hand.
I was lifted off my feet and thrown against the drill press. I screamed as i watched the drill now start cutting the glove and
could feel my thumb being pulled on and wrapped around and over the adjoining finger. I could now feel the drill cutting my
ger. The thumb and finger were just wrapped around the drill and was watching it twist the glove and start cutting it.
As the buzzing in my head started and i knew i was going to faint, i kicked the wall and hit the cord knocking it out of the wall.
I fainted for about a minute and then came through.  F.....did it ever hurt!  I slid the hand down the drill and told the wife
that to i cut my finger off. I now felt no pain so i removed the glove. The drill cut through the skin to the bone.
My thumb was pulled  out of it's socket and rotated about 90 degrees or so. Because the thumb was over top of the
finger it pushed the nail through the skin. It hurt just as much when the doctor pulled the thumb to reset it back into the socket.
I took about 6 months for all to heal. I would say that the finger felt like someone hit the nail  full force with a 10 # sludge hammer.
SO don't thing for a moment that a small machine can't do harm or underestimate the power of a motor.

Beautiful work from both of you! Wow. How long is the wait list? gd, how many hours do you estimate from start to finish? I want to play 1. I am sure my 4 chords wont be worthy but it would still be fun!

I am with everybody else, Nice!

Can you run gcode or do you run a proprietary software with your Benchman?

Just try disabling the limit switches til the project is finished. Then fix them. The sheilded wiring will help but dont forget to separate the stepper and limit switch wiring as them running close to each other will or can induce triggering. Each unit of debounce is a measurement of time the way I understand it. So a debounce setting of 2000 (x 40us/microseconds = .08 seconds). This could be enough travel after triggering to mangle the switch or at least to bend the arm.

Just out of curiousity, what kind of variances are you getting? Is it in the .05mm/.00196" that Hood was referring to?

Ok so I did order an MK6 parts kit. I am going to build that stepstruder head and put it on my A2ZCNC mill. Just 1 of those projects that might take years. Kind of like the lathes and mills in my garage that are under constant change. LOL

Was that San Francisco? That might explain a few things.
