Boxford TCL 125

I do have a UC100 Jazz, so uccnc is not a problem. I was led to believe that to run Mach3 on a 64 bit computer I would need UC100 so am used to using that on a mill . Havent looked to see pin arrangement for lathe . I suspect we have a way to go before we connect the computer

Just to butt-in, use UCCNC for integration and all that, but it doesn't really support lathe operation at all well. That's the only reason I use LinuxCNC on my lathe.

good that the spindle goes both ways.
Mine would jog the axis without a computer attached, gert daft question time, can you turn the pot on the control panel 1/2 way and try again, try with the manual button on
also check the fuses in front of the stepper drivers, (i doubt they will be blown, but its worth checking to knock another potential issue off the list).

The stepper driver manual is available online, download it as it shows how they are wired.

Limits looks like someone's borrowed a part or 2 off the z limit, the black switch just behind the chuck and in line with the top of the z axis is your z limit switch, on top of the axis are a couple of holes this is where the limit switch adj rod fits Yours seems to be either invisible or missing. Operate the switch a couple of times with your finger as they some times get stuck, on the righthand side of the front your lathe is a hole with 4 3mm threaded holes around it, there should be a plate with a switch on it, which allows you to jog off z if the limit switch is on. Don't worry about that now i put it there as i might have forgot to do it later.
If you remove the Boxford plate on the l/h front side it will give you access to the limit switch wires, and the wires for the index and position wires
Don't connect to pc just yet, as it's better to check things work, It does look like someone converted it in the past what to your guess is a good as mine.
let us know how you get on especially after you move the pot,.

My boke i fely dirty when i converted it to -ve earth and fitted an old jap reg/rec i found in the shed, put some better coils on and cried when i fitted a boyer ign kit

This bike was a leg breaker so we did not feel guilty having converted to electric start . I was invited to do an article for Old bike mart.so I f you want to give me your email I will send you a copy.

Do you have a pic of what the rod should look like so I can produce something similar.
Most of the limit buttons seem to have a healthy click but the ball switch , RH side back of the perspex guard has no click at all so doesnt sound to be switching anything. I will take it off and check it out but it looks like I need to remove the fan to get at the switch fixings.

Is there a limit on the X traverse ? I dont see one.

While I am checking these I will take and post pics of the things you asked for .

[John11668]

Some pics as requested







Am in the process of checking continuity through switches ( they certainly didnt stint on interlocks) and looks like there are two circuits
Would be nice to have a wiring circuit for interlocks to be able to test end to end .. I cant see where these are connected to the panel

Door to spindle drive belts seems to have 3. A button switch at opening end seems to have been disconnected, ball switch at hinge end has two microswitches.
Have linked out the suspect ball switch on perspex cover although it does seem to be operating, but still no joy with traverses ,with manual on or Off.

Stepper motors and traverses move freely (untill you switch power on and then the motors lock)

Dont seem to be any homing switches ??
I f you guys have any wiring diagrams then i would love to see them .
If not the guy I spoke of thinks he may have some .

I am using linuxcnc on an Orac lathe. Using two parallel ports one on motherboard and a pci card running an encoder limit switches and a number of control panel buttons. Cycle start stop pause etc. It’s been rock solid since I set it up after the conversion some 8 months ago
I’ve used mach3 but linuxcnc is just sooooo much better
Gmaccopy is a major improvement over axis as a screen interface. All I can say is it just works where as Mach3 would and still does on my other cnc lathe have its moments
I would go to linuxcnc on that one as well but I invested in a pokeys motion controller and don’t want to bin that so mach3 will love on for the time being

Quick question
When i looked into linuxcnc, it said once installed do not update the linux distro.
Is that still the same today or have they found a way to allow update of the linux, was thinking about caelinux as its geared towards cad etc, can linux cnc be added to cae at all

I get the principle on the x limit Inee . I can probably rig one of those .
Am replacing the micro in my Fail safe switch . Seems to be switching but no positive click so I dont have a lot of confidence in it ,.
Where is the ring of interlocks connected to the boards . Wires are hard to trace with all the zip ties they have used.

Cant remember where they connect on the board, what i did when i first got mine was to remove the cable ties and replace em loosely unit i got to the wires i was following, bloody tedious but i got there in the end, i loosely replaced em as it was easier to trace other wires.
just had a look at one of your pics to me it looks like the interlocks are wired to the top board in positions 7 and 8 of the connector which mostly went to the speed controller, havwe a look at one of your images I'm reposting, I've added a yellow circle is the wire in the yellow ring broken(orange wire).
Dead quick check is do a continuity test between those 2 orange wires pin 7 and 8.. if you get no joy try a check between one pin and every wire in the ceramic connector then try the other pin.

was going to log off then had a look at the pics
