Manncorp ECM93 Pick and Place

unfortunately I didn't have a whole lot of time for tuning the stepper speed today so the machine hasn't taken flight yet .
however the machine is faster then it was yesterday. Now I have to find a way to label the A axis a C axis any thought on this is appreciated . And the to do list just keeps growing.
connect homing switches
make feeders operational
and then
and then
and then....

This week I haven't made much progress on the machine per say, however I did find and fix an issue with my fusion 360
linuxcnc post processor not returning the X and Y axis back to the home position.

Isn't it funny how when you get going on a project life jumps in and hijacks everything. I haven't been able to do much
on the PnP ,however I did manage to cross off converting my old Windows XP laptop to linux mint 19.3 XFCE . Then quickly followed
a second and a third laptop ( family ). Unfortunately none of them were good candidates for linuxcnc especially my XP machine, it had a max Jitter of 2.2 million on the base thread. The rest is due to work getting really busy on me so I am stuck to when I have free time
( not much of that either ) to mess with the PnP. I am trying to build circuitry for the homing switches so that when they're in their home position each will light an LED. Of course even that has to throw a wrench into things. 3 of them turn it's photo transistor off when in home position and the 4th turns it on . Oh well it's always something .

when I finally get time again to mess with things I will have to check into doing a laptop with the mesa 7i76e or ed
for my Mill or possibly a Lathe to convert to cnc ( Grizzly G0602 comes to mind ). For now I am using one of the
laptops for evaluation with Linux mint for every day computer use . I like it a lot, I just have to get use to using the terminal for installing most programs . As far as the pick and place is concerned I did get the Mesa 7i75 so I can use the other output port of the 6i25 card
in preparation for actuating the feeders .

The synaptic package manager gives you a GUI interfaces to install programs. As I got more confidence, I moved to using the command line.

thanks rodw I will have to check into the synaptic package manager.

I have to finish working on the openCV plug-ins for QTPYVCP. then you can add a cheap webcam for aligning the pick-n-place head to the parts and also align the machine to fiducials on the PCB.

thanks Bari I will defiantly keep an eye out for that

I'm finally able to get the machine to home itself . I could get the X, Y, and Z to home but the A axis just kept turning
so I figured I needed to reverse the digital logic going into Linuxcnc. ( I will do a video this coming week
about how the homing system works ) after a few weeks trying different circuits I got nowhere. Out of frustration
I did some axis tuning and hooked the A axis home switch up in the same configuration as the others
and it worked . So now I am happy that the machine fully homes and also feeling like a complete moron for not
figuring this out earlier. Talk about not seeing the trees through the forest. Now I just need the get the feeders to
advance on command how hard could that be?

P.S.
Yes I do actually know I am in for a real fight trying to figure it out.

So here is video 6 . I hope to have the temporary homing control board ( perf board with some led's and resistors ) built soon.
I am one step closer . Sorry in advance for the shaky cam work. One of these days I will actually get good at shooting video.
