Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?
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!- Jim Wilson

Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?
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 ball-screw being jammed, or whatever, would affect test results. Something occurred to me. I went...- Jim Wilson

Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?
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 at essentially a constant speed. At or near the end of its journey, I heard a few or maybe several...- Jim Wilson

Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?
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. As usual, you bring up the useful points. My machine does get homed at startup, but we have been...- Jim Wilson

CAN P with no dedicated P key?
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 respond to there, just to close this one off as solved. Thank you, again. You have been very...- Jim Wilson

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 jogging +X, but the carriage doesn't move. In other threads on overtravel issues, I've seen...- Jim Wilson

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. Short Story: Please help me correctly recover from a severe X-axis hardware overtravel. I powered up my lathe with the X- and A-axis motor leads disconnected at the servo amp...- Jim Wilson

Hardinge Conquest T51 X-axis hardware overtravel - my fault, but how to recover?
Please help me correctly recover from a severe X-axis hardware overtravel. Short Story: I powered up my lathe with the X- and A-axis motor leads disconnected at the servo amp. Wham! The carriage fell from its top position all the way down against the hard stop at the bottom. Unsurprisingly, I...- Jim Wilson

750 alarm: serial spindle woes
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 get back to me by tomorrow morning. I've got my fingers crossed...- Jim Wilson

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, it decided to make itself permanent. :( Because the alarm had been intermittent, I expected an...- Jim Wilson

Making Nylon Washers
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 virtually any cutter. De-burring, nylon parts take probably 5 times as long as the equivalent in...- Jim Wilson

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 structure of any of these files. Does anyone have any knowledge about this? In particular, I would like to...- Jim Wilson
