I have experience with their manual lathe 1640L... I had my hands on it at Laney college here in Oakland. Its a pretty AWSOME lathe and I really enjoyed working on it. It is dear to the machining...

Any comments.... please:confused:

Hi,

I was wondering if tormach has a spindle brake mechanism that can be controlled through Gcode? Can tormach (770) be programmed such that it has a holding torque when the the spindle is not...

We can opt for a G540 steppter drive for XYZ and a servo drive connected to the A axis... all of them connected to mach3 via a smooth stepper.

In this way, I can do both lath operations and...

Ok, here’s what exactly I would like to do and I am wondering I can achieve this with a taig (with its backlash). Any feedback will be highly appreciated.
I would like to make Double Enveloping Worm...

Too much of programming is getting confused: VNC & VMC :-(

Here are some videos:

Jeff & Fly_boy_bc, thanks so much for your time. I intend to write G-code by hand since VNC maching on a normal mill is not supported by standard CAM software. Also, I am comfortable programming...

I suppose we have more hope on the way:

Thanks so much for the info.

Hmm… I didn’t see this ‘type of ball screw’ issue coming. I learned how to deal with backlash through the old school and I am fairly confident; except for a few...

I come from a non mechanical engineering discipline. I got the opportunity to learn machining recently (early 30s) in a community college. I never knew what a mill was until recently and how metal...

Hi everyone,

I am looking to purchase a benchtop CNC mill strictly serious prototyping stuff

>> Obviously, the solar thermal approach is much less sensitive to imperfections in beam uniformity that triple junction pv.

This need not necessarily be true in all the cases. Lets look at the...

Ya, I definitely understand the mine fields we are looking at here. My understanding is that most of the solar thermal related technologies such as solar dishes, reflecting heliostats, solar...

Never mind... my message got posted anyway....

Thanks so much for your time and advice. So, here are some specs and directions that I am looking at:

In general, solar trackers can be classified into to two informal groups:

Hi Everyone,

I am an electronics newbie who just learned how solder circuits on a prototype board. I am currently working on a project that requires interfacing stepper motors with my...
