Probe_basic Toolchanger

Mesa 7i76E has two more IDC26 headers, each of those have 17 IO pins that can do high speed stepgen, encoder, PWM, etc.
Use those if they are free.

Tommy,

The stock Probe Basic control scheme doesn't use carousel.comp.  All platter movement is controlled in the ngc files using parameters and motion.digital-out (or in) and motion.analog-out for the pocket number command.

My modified version of PB does use carousel.comp because I'm using a stepper in position mode - no geneva wheel - and I didn't want to treat the ATC as an axis.  Andy Pugh modified carousel.comp to send position-mode pulses to a stepper dive rather than treating the stepper as a velocity-mode 'dumb' motor.

The experimental version of carousel still needs some work (jogging doesn't work), but it's driving my ATC now.

Yup, i followed the development there, and that is the main reason i started thinking about making a TC.

I've collected every ATC example I can find on the forum and github. Rack, ATC-as-axis, carousel.comp, Classic Ladder, etc.

I don't have a double-arm ATC, nor do I have an example using an external controller (arduino, PLC, robot arm).  And I'm limited in my knowledge of programming GUI's to interface with ATC's.

When you're ready I'll be happy to help - it's the least I can do to reciprocate.

What isolation - if any - would be used/needed for those IDC26 headers?  I've come across threads where PCW has mentioned using those pins, but I cant remember what the best way to physically hook them up to a drive (or other component for I/O).

ok im thinking about that for one night....

so i think i will order a second Mesacard....

what do you say is the best doughtercard for my mesa 7i76e?

7i76 or 7i85s or 7i78

7i78 only have 4 more STEP/DIR Ports and 1 rs422
7i85s does have 4 More Axis, 1x Smartserial, 4x Encoder

or 7i76 for 4 more axis, 32inputs, 16 outputs, 1x rs422, 1x encoder

i think i will order the 7i76

7i76E+7i76

a homing sensor is already placed on my TC prototyp
