    Eh, I think I will remain in bliss on this a bit longer... :D

    If it proves to be an issue--I'm takin' your word that it shouldn't be!--then I'll have a stab at tricking it.

    Cheers!

    Yes, I think you are right about no need to push. I was hoping to move it up out of the limit, to troubleshoot the other issue without any concern that the presence of the overtravel alarm or the...

    So, I'm not the first one to witness this? :D

    Yes, as it fell, it sounded briefly like the motor was being "spun up"--this happened quite rapidly--and then it seemed to travel the rest of the way...

    Thanks, Fred. Your questions mirror mine. I have the manuals for this machine, but didn't find an appropriate procedure. I probably just haven't looked in the right place.

    Also, thanks again, Ox....

    Thanks, Ox! That answers the P/Can question--I just wasn't sure whether it applied to my machine, or whether the Shift key would be needed, or what.

    What you mentioned about the other thread, I'll...

    CAN P with no dedicated P key?

    Hardinge Conquest T51 with 18T control. On my control keypad, the P is actually a Shift-O; the key is marked "O/P"

    Trying to move the carriage out of the -X hard stop, I hold E-Stop Reset while...
  7. Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?

    I posted this in the Hardinge forum and received the suggestion to post here, since it's a CNC issue. Hope that's ok.

    Thank you.

    I called this morning and ordered the IC. They had it on order from Japan (none in stock), ETA end of last month. I asked if they had any way to expedite the order and they said they'd...

    750 alarm: serial spindle woes

    Until yesterday, I had occasionally witnessed a 750 SPINDLE SERIAL LINK ERROR alarm on my Hardinge Conquest T51 lathe (Fanuc 18 control). Hit the reset button and it would go away. Yesterday morning,...

    I make a lot of acetal parts and some nylon. Acetal is a cakewalk to machine -- especially compared to nylon. Even with very sharp tools, nylon hates stock removal; it prefers to deform away from...

    Fanuc PMC download data format?

    I can download the PMC data (ladder, params, etc) from my control into any of several file formats: Handy, MCARD ("memory card format"), ROM, etc.

    However, I have no information about the...

    Enjoyin' the show? :D

    There's a little progress:

    1. I've got Fanuc's Ladder III, but my PMC is type RA2, which apparently isn't supported. So, I tried configuring for RA3. Importing the...

    Problem solved, only one step back now

    I made a little discovery: you don't have to be in MDI mode to set PWE if you haven't pressed [E-Stop Reset] yet. With that little tidbit, I could clear K03.0/RTOPT, and voila, she homes like she...

    That does sound reasonable, but I have no clue what, or how to find out. I've been thumbing through the ladder trying to find what signal isn't happening, but I'm empty handed so far.

    Well, mine at least has never homed unless it stopped on its own on the -X move. If you try just pressing +X after moving -X an inch or two, nothing happens. The cross-slide doesn't move at all.

    Ok, so it won't help me now, but how do you do a P/CAN with no P key? Just use the O key? :confused:

    No, the zero return procedure is supposed to go like this:

    2. Hold down the -X button until the...

    How about this for a logic puzzle:

    I wondered if changing the K03.0/RTOPT bit had something to do with the machine not homing anymore. I don't see any reason why it should, but just to be sure......

    Are you slotting these before running the dovetail cutter? IME, they can't do the whole cut from the git-go.

    Oops, my bad. Missed the line where you said that.
