Hope this day finds you all well,I have been reading posts for sometime and just want to say thanks for Sharing your knowledge, experiences and expertise
Now here’s the situation I am building a CNC Router, work envelope of 62” x 98” with ball-screws and linier slides on all axes dual ball-screws on the x with a slave motor
I’m also using servo motors and gecko drives
The machine is about 75% complete
And I’m working on the controller
I have heat sinks for all the drives, my power supply, my control box, fans for cooling, sensors for over travel and homing,
Touch screen, 7.5HP Colombo spindle and VFD, vacuum pump
But I have not purchased breakout board
Because I do not know what board or combination of boards I need
I have read so much material that I just don’t know how to make a decision on what I need
So I’m asking for help
I will tell what I want to control from my touch screen
1. Vacuum hold down
2. Spindle off and on
3. Spindle speed VFD voltage 0 to 10 (do not want to use a pot)
4. Home machine From Touch screen and home individual axes at my discretion
5. Also turn off and on dust collection
6. E-stop reset
7. Tool height touch off plate
8. Pop up Material Locating pins I have built into my table I don’t think machine should move while locating pins are in the up position (all axes disabled when locating pins are activated)
9. I also have a pendant
I have looked at all kinds of boards just don’t know what to buy to get me where I want to go using Mach3
10. I will be adding a forth Rotary axes (technically 5th axes)
Any help would be appreciated
Thanks
