Just to be clear.. Between hal and classicladder - 90 to 99% of what most people need to do with linuxcnc don't need to program in C..

Printer port vs external interface hardware (mesa)

The PID module within linuxcnc had a ton of parameters.. PID of course.. But also Feed forward 0-3..

Cool - One of the linuxcnc developers fixes watches. He is the only person I know that can re-wind accutron coils - amoung other coils.. (he fixed my accutrons) These are tuning fork watches from...
Can you remember what you were wanting to accomplish in linuxcnc?
Yes.. Kins is one of linuxcnc's strong points - but certainly isn't for the faint of heart..
Raises hand...
I can only give you educated opinions on closed loop servo/stepper drive combos.. (I have never actually used any of said drives - so you see where I am coming from)
If they are...
getting closer - using a single tooth index to do some simulated threading.. (and home switches..)

+/- 10 volts out of the printer port..
Found some circuits here.. https://www.eevblog.com/forum/beginn...to-10v-signal/
The first one from the forum seemed simple enough to try - although it...
Also playing with missing tooth index (so you can have in effect a 2 channel (A+Z) using 1 input...)

This is the X axis ball nut assembly fit.

Thanks!
If you want a painfully long video - I go through my thoughts on setting up the turret...

This is how I am setting up the pins.. I do have a turret now - so that will be pin 9
Looking at the parallel port - it looks like I have a pci version that runs what is called x mode. This...
Oh - and homing of the X axis...

Here is my latest video - just a quick overview so far..

I have been working on this for a while but finally got back to it. Using linuxcnc and PWM out of the printer port to $3 pwm modules. The below block diagram is pretty much how the loop is setup.. ...
wow - that is just crazy.. I wonder how many people actually know how well their machine is following the commanded position...
The other option is to add a spacer in the Z column... I did this on my 440 prototype. (the machine had lots of issues and wasn't the supplier tormach went with) I added a good 5 inches of cast...
I stand by my statement that you have no control over the exact path following tolerance in mach...

That is smurf -...
You don't understand. normal machine controls have a way to tell it how close it follows the programmed path. You don't have to guess. You don't have to slow the machine down if it doesn't follow...
So - do you know how well mach3/4 is following your programmed path? you don't do you. I can tell you when I am cutting a part - it is following the programmed path within x.xxx. No matter how...
No.. No no no...
The acceleration should not matter as to how well a machine follows the programmed path. You should be able to tell the machine that you want it to follow within a tolerance. ...
The only comment I have about mach3/4 trajectory planner is that the path following control is pretty poor. (I mean - I haven't looked at it in years) the last I looked - you had to create an angle...
What problems are you having with linuxcnc and mesa? The linuxcnc forum is full of very knowledgeable people and very helpful.

That cutter (spindle) isn't an axis. The x-y axis are slaved to the spindle encoder. (Kinda like conventional threading)
Over on home shop machinist forum Sir John (RIP) was trying to do hobbing by syncing 2 servo drives. He finally gave up and ended up using linuxcnc - which he hated.. But it worked and it was...
Wow. Some really good conversion here...
Couple things..
Linuxcnc has already been used in hobbing applications.
Linuxcnc works with ethercat.
You don't have to 'compile' linuxcnc unless...
also hooked up the light!
