7i80hd_25_2x7i65.bit has 2x BSPI and 16 muxed encoders

(which would work for testing even if
you don't have muxed interface hardware)

It sounds like you would want custom formware


mesaflash --device 7i80 --addr 10.10.10.10 --write  7i80hd_25_2x7i65.bit

it writes and verifies but then in halrun I get a different error. I tried
this several times.

hm2/hm2_7i80.0 Low level init 0.15
hm2/hm2_7i80.0 invalid IDROM type 65535, expected 2 or 3 aborting load

also when you say 16 muxed encoders how are these muxed?

regards,

Muxed encoders are 2x multiplexed (even/odd) by a single output pin

Umm not sure what the error is all about, maybe communication issues?

I get this with 7i80hd_25_2x7i65 firmware:

Re: [Emc-users] can I hide the nativecam interface

2022-01-27 Thread Thaddeus Waldner 
I’m not sure if you can “hide” NativeCam once embedded, but it’s possible to 
use it as a standalone application. That way it won’t take up space on your CNC 
gui.

The problem with trantorque comes if you want a very small motor pulley.

What I have done in that situation when there is a thread in the end
of the motor shaft,  (in addition to the things already mentioned) is
bore the pulley tapered, then use a bolt in the shaft threaded hole to
pull a matching tapered split collar in.

have a numerical spindle number. master had grown the ability to control 
more than one spindle some time back, and the S argument now expects a 
following number before the speed of the numerical assignment of the 
spindle number. All my machines only have one, they start at base 0, IDK 
what the max is, so the argument for my stuff is S0 500 (or whatever 
speed you want to assign to the first spindle.)

However I suspect something else is aglay besides that, so I'll leave it 
to the experts. I did see you're on buster, but not what architecture.

Cheers, Gene Heskett.

Go to store.mesanet.com, find your card then click the "Specification"

Re: [Emc-users] miniature taper-lock type pulleys

2022-01-27 Thread Todd Zuercher 
One machine I have is using some of those Transtorque taper locks.  For a 1/2" 
shaft they require a 7/8" bore on the pulley.  It works very well in the 
application we're using it.

Attached if it passes, is a piece of the openscad screen show that 
armature as its printed right now. The reduced diameter extension 
projects out of the back of the housing to engage as much of the 8mm 
motor shaft as possible. Unshown on the bottom is a pocket for another 
metal bearing that is optional. If its installed at about $1.75 
additional cost, a printed peg is inserted thru the 53 tooth output 
pulley center hole to engage the 10mm bore of that bearing to help brace 
that end of the armature, and that is in the one running on the kitchen 
counter, but is not doing enough to warrant its continued use and 
additional cost. Everytime I print another of this part, I reduce the 
diameter of the hole another .01mm which should hold it a bit closer to 
centered. The hole sounds oversized, but remember the nozzle is .4mm, 
meaning its lying down plastic at 8.35mm whose half the nozzle diameter 
smaller for the inside measurement or around 7.97mm, so it is a drive 
with a small hammer fit the first time installed on the motor shaft. 
Accuracy and a 3d print do not really belong in the same paragraph. :o) 

Cheers, Gene Heskett.

If you're 3D printing a larger pulley, you could do something as in the pic.
You drive a self-tapper into the small hole on the left to clamp the
flexure.
Add more screws/holes as needed.
