Boxford 165 HMC

[chris w]

Yes the tool length differences are a concern but my vertical denford doesn't have an ATC so I have a rack with numbers on it and the program has text in to tell me the tool number and descripition,
but that is why I want a tool setting probe on this machine I am hoping to be able to check/ set the tool length.

the difference in voltage between the CSI lab and the stepper I don't know about because I had a chap helping me when I first got the machine a year ago, and he advised that the CSI labs equipment was the way to go as you can keep all the original motors and drives but after we fit the CS labs unit I think his personal circumstances changed as I cannot contact him now.
he also owns one of these machines and told me there was only 16 made.
i will take you some pics of the wiring, I cut the wires and connected them into where he told me, the machines axes were smooth and quiet at 5000 mm/min Rapids we then set out to rewire the spindle as when we powered the machine up the spindle was always running at about 100rpm with no command, and even when we command m5 still it run,
but since then I have no contact with the chap so the reason that I so stuck.
cheers for the manual,

Always 100 rpm is a bit slow. If you haven't a problem to switch the motor manually on and off, maybe with the front switches, than you can connect the 2 wires directly to the relais, like original. Than you add a 10K rheostat to change the speed from a 10V connector to a outer contact. The slider goes to the +10V connector of the iso-Board. If I come to the machine the next days, I'll make some pics how the switches are connected in original. The CSMIO Board have 2 analog outputs, you need only one for the speed regulation of the motor.
If 16 machines are produced, then they are not so seldom, as I thought, but how much exists today?

Ok from the existing wiring on the drives you can see where they have been connected to the CS labs and you can also see the "extra" wire I have soldered onto the connector,
that hot wire you mentioned earlier goes to the large contactor (enable activated) which has a 240v wire to one of the contacts, so I am now in a position that I have no reverse (m4) but I have control of m3 but the spindle still runs slowly at power on I have got hold of the collet chuck in the spindle and it's not driven with any power,
have you got homing switches on your machine?
i have moved axes to their extremes tonight and marked it with a permanent marker to measure stroke lengths and see where is best to locate the switches, I found the CS labs mpg unit to be very notchy in movement I need to figure out how to smooth that out, but all in all much more positive about the machine now, thanks for your input guys.
