Apparently available in June it looks like this version of the Beagle may
well be a good successor to the original Beagle and MachineKit.

Where I'm still having trouble is understanding the compromises.
Using G02 I,J motion it's possible to specify a feed rate and spindle RPM that
remains constant regardless of the spiral diameter. This approach generated by
the CAM software does a number of segments. But since a spiral is
I'd take a closer look at the power supplies. A system from 1997 could easily
have electrolytic capacitors that have aged enough to no longer be effective.
If you have an ESR meter you could pull caps and check against new ones. Or
just go whole hog and replace them all.

A friend and I have been discussing exactly how to write the G-Code to
create a spiral scroll.
His rotary table 90:1 reduction with a 1600 micro-step motor could be set up
to move N steps for each step of the X axis to create the spiral. But that
approach seems clumsy.

Does anyone have a generic GibbsCAM .pst file for LinuxCNC?
I've generated G-Code for a FANUC but comments start with a '*' and it has
rigid tapping using G84.1 and G84.2. I replaced those with G84 just to see
if it would load. Had to add an M3 in front of the S300.

Quick question here. The HAL file has two time intervals I believe in

BASE_PERIOD = 24000
SERVO_PERIOD = 100
So BASE_PERIOD is about 41.67kHz and SERVO_PERIOD is 1kHz?

Thanks to everyone who worked on this. I do understand just how much is
involved to get to a new release.
First question on this subject then. My LinuxCNC on the Pi4 is 2.8.4 on
Buster. A sudo apt-get update does update some files but then says other paths
won't be valid for 17 days and
My guess is it doesn't. At least not directly but likely could have a cape
built for it that does. But unless it has the co-processors, like the original
BBB, to handle say a 5 axis mill and VFD for the spindle I don't see a future
in it for LCNC. If the FPGA programming is required for the

OK. 500kHz max step rate.
Max micro-steps/step is 16. Standard stepper motor has 200 full steps per
rev so that's 3200 steps/rev or 156.25 revs/sec at 500kHz max step rate
which is 9375 RPM. Yeah right a stepper motor turning that fast.
And their data sheet also states 200-51,200 micro steps in
This might be a silly question but if you only want to move it one step then
does the step line stay high? When does it go low? After all the next step
might be in 30 minutes so should it go low in 15 minutes? That's quite the
lookahead.
Enquiring minds wish to know. ;-)

Yes. That's way faster tapping than I've done. I'm going to have to try
tapping that quickly just to keep up. ;-)
But I'm not so concerned about being able to tap slowly. Just that I want
to see the behaviour and how the trajectory planner handles hand turning the
spindle and have the Z axis
How would that be done in the HAL file?
And BTW, Peter could probably explain why but when I bumped the RPM up to

velocity profile. Just at higher rate.I'm guessing that even though the

My biggest issue with the Xylotex BBB Cape for CNC was that the logic for ESTOP
was inverted. ESTOP was a N/O switch so if a wire was broken you wouldn't find
out until you tried to save a body part from being injured with the ESTOP.
But back when a BBB was around $50 and a cape around $25 you
I'm curious. I have one of the original Xylotex boards. The link to this web
site implies there's a newer version along with a link to 4GB BeagleBone Image
for MachineKit which I have read hasn't been supported for years.

Raspberry Pi Desktop.
Is it possible to install LinuxCNC into this environment?
I did try:
sudo apt-get install linuxcnc
It reported an error
E: Unable to locate package linuxcnc

However it just stops at the end of the retraction point. The S200 M3
doesn't occur. No fault message.
