set step switches
5,6,7,&8
to--- off,off,on,on
8th step
stepper motor 20 steps per revolution 1.8 DEG = 200 steps.
So that 1600 steps per rev
I thought the ball screws were in inches they are not
they are metric
I MDI command X 7 inches machine moves to 6.889 measured
Display shows 7.0000
machine moved measured 175 mm=6.889
stepper motor made 35 turns
SO to calculate of a metric screw
turns per inch for a metric ball screw
7 inches =7*25.4=177.8 mm
177.8/35=5.08
so 5.08 = number of turns of the ball screw to
get inch inch of movement
hope this help some one ?
machine now moves the correct distance
YES 7 inches
8th step plenty of Power no stall
forgottoturnonspindlemotor
end mill pushed part out of vise ?
still attempting to mill
been using MDI
switch 4 set to off (off makes power reduction to on ?)
123
for X,Y on off on
for Z on,off,off
motors have been on for over a hour and are cool, not even warm!
and had Power to move
DO NOT FLIP SWITCHES UNDER POWER
U will Blow the drive
No Smoke 2 ?
OK that all for now
Thanks for sharing. I'm starting a build to convert a Seig X2D to CNC. When I get to assembly I'll definitely be looking at the relevant formulas.
My original plan was to convert a little machine shop 3990 mill to cnc so I bought the cnc mechanics and electronics at the same time. My problem is that I like having a manual mill in the shop. I decided instead to buy the Seig for CNC.
I am interested in where you got the abs case? I've been looking and the closest I found is a metal cabinet used to make electrical connections. If I go that route I'll need to make sure to isolate everything from the case. I also like the aircraft connectors which would mean drilling fairly large holes in the metal case. The plastic case would eliminate those two problems.
