Re: VisualMill, which post for Mach1?
Roger,
You'll probably have to modify an existing post to suit your needs. I use the Flashcut post and have found that it is pretty generic and probably a pretty good starting point for Mach1. Once

Re: Has anyone built an SPC display for Digimatic scales?
Has anyone built a purpose-made box for displaying the output from this type
of caliper? I'd like to avoid using a computer if possible.

How do I 'make' a ballscrew antibacklash nut?
Hi all, I'm kind of a CNC newbie.
I've converted my Grizzly G1006 to CNC (Master5/Mach1 and Camtronics
4 axis servo), but the backlash and lead accuracy stink.
I understand I can get decent/cheap

Re: Chain drive
Bob:
I built an X-Y Table once where chain-drive was used to connect the MOTOR to

My 1" acme leadscrews are 1" OD (ie 0.990 - 1.000" major pitch dia).
As the minor dia varies (.7509"-.7800") you can use a .75" ID or smaller
bearing.
If you are looking at the 1/2" acme

Re: Ball/acme screw question
JJ,
You do not use the O.D. of the screw in the I.D. of the bearing. The
ends of the screw are machined or ground to the next standard size down, to
a snug fit in the bearing I.D.. My R & D in

Re: Ball/acme screw question
Thanks for all the info everyone!
One last (for now) question: Are acme screws their true diameter? Ie. If
I buy a 1/2" screw, do I plan on using 1/2" ID bearings?
Okay, one more: Does anyone make

Re: DRO encoders- Rotary or Linear?
Instead of using a rack and pinion, would it be possible to use a rigid bar
(like 1" or 1.5" drill rod) and a rubber roller mounted to a rotary encoder?
With a solid bar, wipes could be used to clear

Re: plasma cutter/machine torch
Dave,
You might find an OK el cheapo plasma but the Hypertherm and Thermal Dynamic plasmas are the real deal. On the other hand some of the el chepos are real junk. So make sure the machine will do
