FAQs / Straighening Thread Bar

« on: January 02, 2010, 11:37:19 AM »

Sometimes rolled ACME ,thread bar etc comes slightly bent. After trying one or two ideas a simple clamp was made up from a piece of suitable angle iron to straighten the bar. This consists of two fingers blocks about 9" apart approx. With a tapped hole on the opposite side in the centre to take a M12 setbolt. This clamp is simply put onto the bar at the high point and by slowly adjusting the M12 setbolt with a piece of plastic on the end to protect the thread the bar can be adjusted straight. . The high point can be found by watching the bar rotate or by a good rule against along the centre line of the bar. But take it easy don`t bend it to far. Some idea can be obtained was remembering the position of the adjusting spanner.

Today tried another computer which we know is O.K. on another system, but gave same result letters at an Angle.
So tried smaller steps the angle straightened out but the whole system much to slow, slow as a snail, now we have a kernel warning. DECIDED TO AWAIT FOR ANOTHER CONTROL BOARD to try.

Thks for reply Graham, using 16mm x 4mm pitch   screws, no not resonate, have made adjustable nuts for square thread so can take out any play that may be there. It seems like when in the programme does not like it the slower turning.

Using Mach 3 on win. XP 2000 P4 2.0G sets up OK with ruler on the X & Y but when in a known good Gcode programme slants at 20 degs. Htkeys seem reasonable on the stepper movement but when in the programme sounds noisy on the Y . Steppers have been changed around and drivers but still the same. Using Arc Eurotrade steppers and driver boards all opto isolated. We have changed most  only the control board to go and any suggestions on the computer ?
