IIRC the datasheet says it

OK, NOW it makes sense! Can't be terribly fast if it needs
resistive pull-up though.
Thanks!

Good start. But a 9x20 that weighs 750Kg/1650 lbs? Unreal. I should be
so lucky. :)

Hi All,
Wondering if there is a preference to G73 or G83 for drilling and clearing
chips (which I think I want to do for aluminum drilling).

Thanks,

If it takes pulses for position control then pretend it is a stepper
system. use 1:1 gearing, x1 micro stepping and 2500 s

Beautiful lathe Andy and quite a heavy one!
We have two big hydraulic tracer lathes (one weights almost 1 kg and
the other 5000 kg) that are waiting for a LinuxCNC conversion. The
challenge is that these have to be modified to have the perpendicular way
since now it's angled to suit the copyin

Hi,
I have Adtech Q7 series drive and 1.5 kv close loop motors I am trying to
configure with EMC2 but on basic setup there is no servo motors
configuration.
What I I know about my drive support 2500 pulse /revaluation I other
information I need to putt in basic configuration?
Please reply
Hey Andy - reading your web page - Ok - the Emco Compact-8 was the one
copied extensively overseas. It was made in Austria originally.
The Compact-8 is approx 8" diameter swing and 18" between centres. The
Asian 7x lathes are NOT equivalent, and are NOT copies of the Emco
Compact-8. Some of the 9x
I am converting a Holbrook Minor lathe to CNC.
First stage, making it run on domestic power:

If you can't fix it, you don't own it.

This reminds me. My Holbrook has a Poly-V belt. It's probably bigger
than you are considering, despite only being a 9x20 lathe:

That's not the way that I inter
