I guess you can use the proximity sensor. I have that on my denford mill.
The sensor sits orthogonal to the spindle and there is a setscrew that protrudes from the spindle.
Every time the screw passes the sensor one revolution has occured.
The output of the sensor is wired to an input pin on your breakout board and configured as index in mach3.

Third party software and hardware support forums. / TB6560 Spindle speed

A gecko won't give you spindle speed ;)
You need to either make a black'n'white sensor setup (don't know the exact term) and hook that up to an input pin or install a rotary encoder on the spindle. The latter will provide for a more precise rpm count as it's 1024 impulses per revolution.
I went with the encoder and switched out the Chinese BOB with a CSMIO-S and eventually geckos for the axis steppers.

Depending on what you want for them I might be interested!

It sure looks like it, albeit a generation or two older.
Might be a fun project for the lathe and good practice for me ;)

No worries :)

I just found out that my triac isn't ISO30 but instead R8.

It has a quick change tool holder of sorts that I think confused the seller about the spindle.

So now I'm thinking I'll machine holders for that and forget about atc for now  ;D

Do you perchance know what the holders are called?

Regards,
Jens

Hi Jim,

I just picked up a triac without the atc.
Doing the conversion to mach3 as well.

Do you still have the dumped atc on hand?

Regards,
Jens

General Mach Discussion / Re: Cannot move Z negative
« on: October 27, 2013, 03:52:19 PM »
I'm using V2.040 but it works fine if I start on a new configuration.
Just don't know where to look in the old config to spot the problem though.

The signal from the Z home switch is ignored in the homing cycle (ref all home) so I press E-Stop as the Z axis is at it's end and making noise.

General Mach Discussion / Cannot move Z negative
« on: October 27, 2013, 10:41:35 AM »
Hello,

I've been trying to mill a pcb today and ended up with some imperial (G20) gcode.
Now I cannot move the Z-axis in the negative direction anymore.  ???

My MPG only reacts to Z-positive.
If I enter in MDI, say G0Z-1, the machine goes into e-stop with the message "Limit Switch Triggered"

The only switches I have on the machine is reference switches of which the Z is also ignored.
Can't say about the others as Z is the first one being referenced.

I've attached my XML for the machine.

Thanks in advance!

Have a look at pcb2gcode. http://sourceforge.net/apps/mediawiki/pcb2gcode/index.php?title=Main_Page
I use it to convert fritzing made gerber files to gcode.
It's part of the standard repo on ubuntu. Haven't had any luck compiling on OSX.

General Mach Discussion / Decimals when sending DRO's via MODBUS

Multiply by 10000 before sending and divide by 10000 at the other end?
