Re: [Emc-users] missing tooth index questions..

yep - andy is a genius... (and halscope is really cool..) I triggered on the rising edge of the index enable and put it one rotation back.. You can see the position is counting up by .01 each time by the steps. Then the gap happens and the next step is .02 so the rotation position ends at 1...

Re: [Emc-users] 7i76e with Rpi4

Sam and Robin, I found the immediate problem. The address should have been 10.10.10.10 rather than 10.10.10.11. I have a CNC’d Grizzly G4000 that is running a 5i25 with a 7i76. I tried wiring the 7i76e the same as 7i76. LinuxCNC fires up now but none of the motors spin. However, the motor all hol

Re: [Emc-users] missing tooth index questions..

ok.. It might be working? I made a hal component that would set index enable to true after so many encoder counts. I set it to 998 (<10 rotations) to set the index enable to true.. and the encoder position was 9.98... so it isn't losing every rotation. so I 'think' it is working right... ht

Re: [Emc-users] missing tooth index questions..

Much easier to visualize if you use less holes I think? I first made 6 holes and then laid out two arcs and created a longer slot from two of the holes. I count 5 holes and 5 spaces between the holes. Are you sure you actually cut 100 holes? John Dammeyer > -Original Message- > From

This may be a bit wild  but use pll and trigger when the expected pulse doesn't appear. Maybe a bit far out of the box. Basically the reverse of synchronous detection. D On 9/18/22 1:59 PM, Sam Sokolik wrote: in case that screenshot didn't come through https://electronicsam.com/images/emco/Scr

indeen! Spiral out from center going as deep as possible and constand radial engagement. When that is exhausted them try same idea on the triangular remanents. Then go back and test that against Jon Elson's code. Machining is an experimental science. Eh? Dave On 9/18/22 12:18 PM, Nicklas SB Ka

I have a optical encoder from a mouse running on an emco encoder wheel (100 holes). I cut out the metal between 2 holes. I think that would be considered one missing tooth... I have the encoder scale set to 100 and the missing tooth set to 1 I have a little comp that sets the index enable to tr

Re: [Emc-users] Pocket milling

I was not thinking to much about the corner. If machining with for example 50% tool engagement then end is reached machining at 90 degrees into material and tool engagement increase to 100% before next pass. An alternative would for example be to machine into material with an angle. For the fi

Hi Nicklas, Just a WAG, offset cutter maybe .25 mm from real corner and plunge then clean up in incrementally with a couple of passes to clean out the wings. I think most cam programs just take light passes including the finish pass. How stiff the spindle is and sharpness of the cutter are stil

That's what I have ... I have it wired directly to the ethernet port on the Pi, I just used a normal cable, Note that when LinuxEMC takes over control of the port, you can't use it for internet/IP connectivity (or at least I can't) so you'll need some other interface in addition to that if you ne
