I have a touch off plate (actually a z height setter that I also use on my mill) that I use to set the lathe tool Z. I zero Z to tool T01, and then set the tool table offsets for the rest of the tools using the touch off (documented in the wiki somewhere). I use a modified tool Z height setter (similar to enco part 636-7044, but mine has a magnetic base). I removed the battery and ran a wire through. The magnetic base allows it to be mounted to the headstock or chuck. -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

There seem to be at least several people using it in production. There are
undoubtedly some remaining firmware and driver bugs, but the basics look to be
pretty solid. (Thanks Sebastian!)

The main advantage of the 5I22 and 5I23 is future growth potential. Here are
some advantages of the 5I22 and 5I23:
1. The PCI bridge chips used on the 5I23 and 5I22 support DMA. The HostMot2
driver was designed at the outset to eventually support DMA to lower the
overhead of card access.
2. The larger FPGAs will support fancier configurations, for example
the resolver configuration I'm working on will not fit in the 5I20s Spartan2
chip (Mainly because theres no hardware multiplier in Spartan2)
3. Higher speed, the Spartan3 chips used on the 5I22 and 5I23 are about 50%
faster than Spartan2 used on the 5I20. This is especially noticeble when
processors are embedded in the FPGA.
On the other hand, the 5I20 is probably overkill for controlling a lathe, if
72 pins are sufficient. (GPIO will eventually be expandable via SPI anyway)
the HostMot2 firmware supports up to 12 axis of servo interface on the 5I20,
so a 3/4 axis lathe is not taxing its capabilities.

[Emc-users] Mesa 5i20 vs 22 vs 23 ?
Hi all, I have a mill which runs a mesa 5i20 card and I am now starting a lathe build/retrofit (more on that later!). Compared to a few years ago there are now three or four variants of these cards available: 5i20, 5i22-1, 5i22-1.5 and 5i23. Also, I know there has been some good work on the modular hm2 fpga-code and emc2-driver for these cards. - How stable is the hm2 fpga-code + driver right now? anyone using it routinely for 'production' ? - Any benefits of the 5i23 (400kgate fpga) over the 5i20 (200k fpga) ? - The 5i22 cards are more expensive, have a bit more I/O, but isn't the large fpga overkill for a setup where emc2 runs the pid-loops on the cpu anyway? For the lathe I will have servos on the Z- and X-axes, not sure about DC-brush vs. brushless yet, but Jon Elsons PWM amps work very well on the mill so I am leaning towards them. Then the spindle will hopefully be driven by a big 1.75kW brushless servo. The lathe project also calls for a revolver-type toolchanger which needs one I/O bit for a pneumatic cylinder, and one servo/stepper axis to rotate the revolver. In addition I will need the usual jog-pendant I/O: MPG (thinking about two, separate for X and Z), a few selection-switches, and some buttons. Live tooling is a dream for the future :) Looking at the schematic for the mill[1], I think the lathe setup will be pretty similar and I should be OK with 72 I/O pins. regards, Anders W [1] http://www.anderswallin.net/wp-content/uploads/2008/09/dc_servo_schematic_2008jan19.pdf -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
