Re: [Emc-users] 8" Rotary Table Index Chart

The FIRST place I looked. Since the item does not have the standard 40:1 ratio, the chart in my 22nd Edition did not have what I was looking for. I did a very nice two pager in Word, have to find out how to upload it correctly. Sorry about the delay. - Original Message - From: emc-use

[Emc-users] 7/G8 is driving me up a wall.

Greetings; Someone on irc said touchoff gives a choice when you have entered the first number. Not on 2.6.7, the only thing it says is radius, so I have to keep a pocket calc, to do a / 2. on the size the caliper reads for the actual touchoff data entry. IOW, it takes radius inputs only.

[Emc-users] 8" rotary table indexing chart

I bought a no name 8" rotary table and found that the Vertex DP-3 index plate set fits perfectly. After looking on the web for several hours for an indexing chart, to no avail. I did one myself. The newer index plate set allows divisions up to 100 without any missing values. - Original Mes

[Emc-users] lathe spindle motor accel/decel recommendations

I am retrofitting an EMCO 120P lathe with new controls. It has a spindle encoder so will do threading/tapping, etc. The 3HP Black Max motor and GS2 vfd combination (with braking resistor) can drive it fwd/rev 0-3500 rpm. It can accelerate from zero to full speed, or decelerate from full speed

[Emc-users] Machine limits question

Greetings all; Is there now, a gcode mode command that when invoked, would cause a loop to iterate to the next pass when a machine limit has been hit? I am out of X backout trying to do this taperlock in a 39mm diameter steel round. I am attempting to scale both motions by counting passes so t
