stepper motor mount hardware did not fit thru. lame.
this made me nervous.
ah, its not too bad once clamped in the little mill. very easy to drill.
Had to do all 16 holes. (4 in each motor)
I don't understand why these motors have a beautiful micro-finish on the mount surface, yet the mount holes were chewed out by a rat.
mounting stepper motors
spring for preload. Accelleration of the motors is tuned for spring weight and mass of gantry. there is a calculation the designers did to make this a balanced system that has to do with accelleration and gear geometery.
installing Z home switch. This is used to find the height of the work before cutting. The tip of the plasma will touch the work while shut off, and the "floating head" will make this switch and the controller will then know the height to pierce or cut at.
attached switch leads to a board in the power supply.
the brown/yellow ones. I didn't need that trailer harness anyway.
lots of expensive things to drill holes in.
computer system. thx to rallyroach for system, Rob for monitor.
the scary side lol
had flakey communication between pc and bladerunner. The LPT1 port screws would not engage. What to do?
Head back to 1939 and cut 'em down to size.
I got a real kick out of this, it was 3am, sorta drunk and really tired.

no load, but the tinyest peice of dirt, or slag could cause a jump, which can break your cut, and throw your tolerance.. i'm sure you know what i mean... most things, a little bit off isn't gonna matter, but i'm sure your used to tolerance in the =/- 0.0001" range... when fitting parts, or machining, it can make a differnce.
strange that a little corrosion would make it skip a tooth. both sides jump, or just one?
i'm sure i could think of a million things that could go wrong... but i'll try not too
have fun with those plasma schematics. they try to make them so most people can't understand them lol

CNCZone.com has a Hypertherm forum with one of the engineers who has been there designing for 30 years answering questions. they provide unparalled support for doing this stuff. I have waded thru the schematics for the last hour, and was able to pare it down to two questions for the support forum. I just posted over there, should have my answer soon.
i hear ya on the tiny dirties. This was leaping from the rack, it would have fawked the part being cut. Some little turnbuckles might do the trick, but no-one else has issues with the springs. I dunno yet.
