Kicad-to-HAL: Proof of Concept

So it turns out a few hundred lines of Python can convert a Kicad schematic:

Gamepad Axis Priority - schematic sample — Gamepad Axis Priority – schematic sample

Into a LinuxCNC HAL machine configuration file:

loadrt and2		count=22 
loadrt flipflop		count=5 
loadrt not		count=8 
<<< … etc … >>>

addf and2.0		servo-thread
<<< … etc … >>>

net X-Knob-Active <= or2.2.out => and2.1.in0 not.0.in
net X-Knob-Inactive <= not.0.out => and2.2.in0 and2.3.in0
<<< … etc … >>>
net Y-Knob-Active <= or2.3.out => and2.3.in1 not.1.in
net Y-Knob-Inactive <= not.1.out => and2.2.in1
<<< … etc … >>>
net _Axis_Priority_XY-Reset <= and2.2.out => flipflop.0.reset flipflop.1.reset
net _Axis_Priority_Y-Disable <= not.5.out => and2.1.in1
net _Axis_Priority_Y-Select <= and2.3.out => and2.7.in0
net _Axis_Priority_Y-Set <= and2.7.out => flipflop.1.set

The Kicad schematic interconnects components from a library defining LinuxCNC HAL devices:

Kicad symbol - AND2 — Kicad symbol – AND2

The process goes a little something like this:

Draw schematic using components in LinuxCNC-HAL.lib
Add missing components to LinuxCNC-HAL.lib
Iterate
Annotate schematic ~~(starting from 0)~~
Generate netlist in XML format
Run Kicad-to-HAL.py with Python 3.9.2 (sorry)
Fix whatever LinuxCNC complains about
Iterate
Fix logic flaws by adjusting schematic
Iterate

The Kicad components include magick HAL features, the Python program rides roughshod over Kicad conventions, and this thing stands deep in “It works for me!” territory, but I must coerce my notes into something resembling coherence before I forget the grisly details.

More to follow, but you can peruse the Python3 source code and Kicad library as a GitHub Gist:

The Joggy Thing vs. LinuxCNC 2.8

After getting the Sherline mostly working with LinuxCNC 2.8 and the Mesa 5I25 FPGA card, I updated the HAL code turning the Logitech gamepad into The Joggy Thing:

Sherline Mill - Logitech Gamepad Joggy Thing — Sherline Mill – Logitech Gamepad Joggy Thing

This required significantly more effort than I expected, mainly because I can no longer edit the Eagle schematics defining the HAL file. In the intervening years, Autodesk bought the Eagle EE CAD program, converted it into a subscription service, sutured it onto their Fusion 360 package, and priced the result far beyond my toy budget. While they do offer a free tier limited to “individuals for personal, non-commercial use”, schematics with only two sheets pretty much wipes out its value.

Because the EESchema part of Kicad can export its netlists as XML files, someone experienced in wrangling XSLT, perhaps using Python + lxml, could recreate the function of the Eagle ULP with Kicad schematics / netlists. I am not, however, that person, although it would certainly be a Learning Experience™ of the first water.

So I updated the automatically generated HAL file on hard mode with a text editor, which, given HAL’s limited debugging support, somewhat resembles juggling a greasy bowling ball, a full-throttle chainsaw, and a squalling baby in a poopy diaper.

The major conceptual problem was LinuxCNC’s recent separation of “axes” from “joints”, with resulting changes in both nomenclature and control. Eventually, I found some key hints in a very recent update to a LinuxCNC wiki entry describing a similar Logitech gamepad interface.

The basic Joggy Thing logic remains the same, with “analog” values from the joysticks now presented to both the halui.axis and halui.joint controls. The new trick of holding the pre-startup values (presumably zeros) with feedback around a multiplexer qualifies as a Moby Hack preventing a startup glitch from triggering an error having something to do with an E-stop.

The machine still runs away on X and Z at full throttle instantly after tapping the Machine-On button for the first time in the morning. Come to find out the gamepad starts up with all four joysticks jammed at -1 until the first activation of any axis or button, which I’m sure it always did, but something in HAL’s bowels now responds differently. More work will be required, although I think the simplest solution will involve holding everything inert until the logic sees a specific gamepad button.

LinuxCNC: Mesa 5I25 For The Sherline Mill

Updating the Sherline’s LinuxCNC from 2.7.ancient to 2.8.1, which I did by the simple expedient of replacing the hard drive with an SSD from the heap and doing a clean installation, provided the opportunity of switching from the parallel port to a Mesa 5I25 FPGA card to put timing-critical step generation under hardware control.

I has flashed the card with Mesa’s Probotix PBX-RF BIT file, then invoked it with a configuration string turning off everything except the stepgen modules:

loadrt hm2_pci config="num_encoders=0 num_pwmgens=0 num_stepgens=4"

Which produces a simple pinout on the back panel DB-25 connector:

The Sherline CNC driver requires an adapter to swap the Step and Direction signals on the output connector.

The Sherline controller expects active-low Step signals:

# invert step output bits
setp   [HMOT](FPGA0).gpio.002.invert_output     1
setp   [HMOT](FPGA0).gpio.006.invert_output     1
setp   [HMOT](FPGA0).gpio.009.invert_output     1
setp   [HMOT](FPGA0).gpio.011.invert_output     1

The Y and Z drivers needed the same Direction swap as before:

# invert direction output bits
setp   [HMOT](FPGA0).gpio.008.invert_output     1
setp   [HMOT](FPGA0).gpio.010.invert_output     1

Because the 5I25 uses 3.3 V logic with interface drivers to match the “parallel port” 5 V levels, it has different electrical characteristics than the parallel port built into the Dell Optiplex 760. Putting a 100 nF cap across the Probe input reduced, but did not eliminate, what looked like a nice 60 Hz signal on that long wire, so I added a firmware debouncer:

loadrt debounce cfg=2
addf debounce.0               servo-thread
setp debounce.0.delay 3

net probe-raw debounce.0.1.in [HMOT](FPGA0).gpio.003.in_not
net probe-in debounce.0.1.out

The additional 3 ms delay doesn’t amount to much distance, even were I to probe at the machine’s top 10 mm/s speed.

Although the seemingly identical Home switch input seemed stable, it got the same treatment:

net home-raw debounce.0.0.in [HMOT](FPGA0).gpio.013.in_not
net all-home debounce.0.0.out

The PID loops have a very simple setup, with P = 1000 and FF1 = 1, which seems entirely adequate without any attempt at tuning. The following errors seems to stay under 20 ppm, in the machine’s native inches, while cutting the standard Axis “splash G-Code” file with all the speeds cranked up to 24 in/min = 610 mm/min:

LinuxCNC - Sherline f-error — LinuxCNC – Sherline f-error

Claiming a 20 µinch error for a Sherline is certainly aspirational.

Adapting the HAL code driving my Joggy Thing to its new home didn’t go quite as smoothly, about which, more later.

Handle With Care – FRAGILE – Thank You

I wonder if somebody took careful aim at this particular corner:

FRAGILE package damage

Well, it arrived in a more-or-less timely manner, unlike some packages and letters we’ve both sent and received of late. Tracking data suggests packages can vanish for days at a time, teleport to distant sorting centers, and sometimes loop between centers.

The USPS may simply have run out of people willing to work under the current conditions.

Mesa 5i25 Superport: Reflash and Step-Direction Pin Swap

For reasons lost in the mists of time, the DB-25 pinout used in the Sherline CNC Driver Box is kinda-sorta the same as everybody else’s DB-25 pinout, with minor difference of swapping the Step and Direction pins on each axis. This made no difference with the LinuxCNC parallel port driver, because (nearly) all pins are alike to it, but having recently found the Mesa 5i25 Everything I/O card and being desirous of upgrading to the latest & Greatest LinuxCNC, I figured why not throw all the balls in the air at once?

Although it’s theoretically possible to recompile the FPGA source code to swap the pins, the least horrible alternative was converting a null modem (remember null modems?) into a passthrough pinswapper:

DB-25 Parallel Adapter - Step-Direction pin swap — DB-25 Parallel Adapter – Step-Direction pin swap

Make sure you put jumper W2 in the DOWN position to route pins 22-25 to DC ground, rather than +5 V. W1 does the same for the internal header, herein unused, but it’s in the same position just for neatness.

Similarly, put both W3 and W4 in their UP position to enable +5 V tolerance, connect the pullups to +5 V, and enable the pullups, thereby keeping the Sherline logic happy.

Jumper W5 must be UP in order to have the thing work.

The relevant diagram:

Mesa 5i25 - jumper locations — Mesa 5i25 – jumper locations

Flashing the 5i25 with the Probotix PBX-RF firmware produced the best fit to a simple parallel port:

sudo mesaflash --verbose --device 5i25 --write 5i25/configs/hostmot2/5i25_prob_rfx2.bit
sudo mesaflash --verbose --device 5i25 --reload

The mesaflash utility and all the BIT files come from their 5i25.zip file with all the goodies.

The Gecko G540 pinout came in a close second and, should the Sherline box go toes-up, I’ll probably replace it with a G540 and (definitely) rewire the steppers from Sherline’s unipolar drive to bipolar drive mode.

The 5i25 pinout now looks like this:

123 Block Links: Sherline Tooling Plate

Because the 123 block hole spacing doesn’t match the Sherline tooling plate’s 1.16 inch screw hole grid, each block has only a single 10-32 SHCS holding it down through a cap screw head pi n:

123 Block Links – Sherline table alignment

The spring clamp squashes a pair of reasonably straight steel bars against the blocks, whereupon gentle tightening can produce ~~perfect~~ Good Enough™ alignment.

You could remove the tooling plate and attach the blocks directly to the Sherline’s table with two (or more!) T-nuts and screws per block. I expect no standard SHCS length would be quite right for the distance between the head held in the block pin and the T-nut in the table slot, not to mention removing and reinstalling the tooling plate is enough of a nuisance I’d rather not do it without good reason.

Just to see how things looked, I attached the cursor milling fixture with threaded block pins:

123 Block Links – Sherline layout

Note that the remaining 10-32 clearance hole in the fixture (for the cursor hub) doesn’t align with the underlying hole in the block; the next fixture must take into account both the Sherline and the 123 block grids, as well as which block holes align with the tooling plate. Bleh!

2021-02-10
123 Block Links: Threaded Pins
The pins capturing the SHCS heads will mount the 123 blocks to the Sherline’s table or tooling plate, but attaching things to the blocks or joining them requires threaded pins on the other end of the screws:

123 Block Links – trial assembly

Optical illusion: those two pins are the same length.

I grabbed a length of 3/8 inch aluminum rod in the Sherline vise, center-drilled four holes spaced 7/8 inch apart, then drilled them with a #20 drill for E-Z tapping.

Space the holes with manual CNC command entry:
```
GO X[0*0.875*25.4]
GO X[1*0.875*25.4]
GO X[2*0.875*25.4]
GO X[3*0.875*25.4]
```
That’s LinuxCNC on a Sherline with hard-inch leadscrews and G21 active. I normally use millimeters, but inch dimensions make more sense for these pins.

Transfer the rod to the lathe for hand tapping:

123 Block Links – tapping

Not shown here: stick a transfer punch in one of the holes and eyeballometrically align tap with punch to get straight threads.

Then, for each pin:
- Chuck rod so the whole pin sticks out
- Turn OD to 8.4 mm
- Face to 3/8 inch rightward from hole center
- Chamfer edge with file
- Part off a little more than 3/8 inch leftward from hole center
- Find pin in chip tray
- Rechuck the other way around
- Face to 3/8 inch rightward from hole center
- Chamfer edge with file
- Ease thread entries with a round file
- Done!
Again, I can’t believe I’m the first person to think of these pins; aim me at the commercial offerings I can’t find anywhere.

Update: The keywords “cross dowel nut” and “furniture bolt” will turn up useful products intended for woodworkers. Thanks to blaz for the suggestio n.
