Bridgeport Manual to CNC conversion...

[njhussey]

Got the lube parts from Lubetec, very fast delivery.

They're stockists for the Bijur range so should be :)

One of the (many) things I've still to do is finish off the control/safety circuits...I've forgotten what I was going to do so probably going to start from scratch again and try to get my head round the subject (I hate electrickery stuff!!) again :) The CSMIO products are good, I'm glad I went with them.

Not being funny (well perhaps just a little) but I would not let mach decide I would definitely tell it which ones to use, the thought of mach going eenie meenie minie mo doesn't inspire me with confidence.. Sorry couldnt resist that!

Let me expand...

I will have two Mach profiles - std Bridgeport & engraving

In profile 1 I have say output 7 defined as active low and no other connection
In profile 2 I have say output 8 defined as active low and no other connection

On the CSMIO each one of these outputs controls a respective VFD these outputs, being active low will come on as soon as Mach has started up and will stay on regardless of Mach reset condition.

So to do engraving I would fit the aux spindle and tell Mach to use profile 2 and so on.

It doesn't actually decide what to do, it just chooses the correct VFD for the profile I click on.

I love the electrickery stuff - I have been cussed many times on here because I try to go too far with system controls etc - I am used to using PLC's and pneumatics at work and it tends to spread to my stuff ;)

I'll come to you then for double checking my stuff then, I did some programming, PLC and PIC stuff on my degree....but that was 15 years ago and I've forgotten more than I knew...which wasn't much in the first place!!

I am doing something similar but with linuxcnc and mesa combo 5i25 + 7i76 so that one profile controls the lathe and the other the mill with one control box

[Davek0974]

Sounds good, two machines with one system does seem to make sense when most of the I/O is the same.

Got the ram and knuckle on this morning, also stripped and painted the saddle and head.



Also fitted a spacer here as the gear mesh was terrible, way too wide. For the first time in all the years i've owned her, the knee now glides up and down silently

Looking lovely Dave, looks so much nicer cleaned up and painted, should turn out to be a nice conversion/restoration.

Got the head on, spindle in and new oil pipes plumbed in and tested.



Also stripped and painted the lower drive housings and scraped out the wax that used to be grease ;)

Looking good Dave, are you fitting new ballscrews you ordered as you re assemble or are they fairly easy to access/fit without breaking down the whole thing again?
