I missed that in the original posting. That translates to your being about to run, all other stuff equal, at about 135% of my best speeds. > Thanks for the pointers, I think you have dumbed it down as much as > possible Being thick and persistant is not a good combination > It works anyway Great! > Richard :) I hear that! I got curious and picked up my table and bolted it down, then started moving recent config values to the 4 or 5 year old .hal & .ini files which were originally setup for 4 axis's. I had to adjust lots of things but I wound up with an mdi 'g0a360' and g0a0 that worked but I have something set too slow as I have no feed override increase available. But it was running error free at 1800 degrees/minute for a g0 move, and can run at 2400/minute once I find where my headroom went. And this was with a 252 oz/in motor on it, not the 425 I thought I had installed earlier. That translates to having 3 425's left to put on a lathe. ;-) By that time (about 1.5-2 hours elapsed) my feet were about to sign off (I'm 77, diabetic and the shop building the mill is in is not well insulated, and its down to the lower 40's here in WV now. I have plenty of 240 volt power out there and keep it just warm enough to stay above the dew point so tools don't rust). I'll likely repeat, with the next session having fresh printouts of the integrators manual available since mine in the 3 ring binders out in the shop are about a year old & Big John Thornton has been busy updating them. But before it gets back to warm weather, I need to pull my drive box off the shelf and ascertain the state of the "idle powerdown to 50% current" dip switch on that axis, that motor alone was running nice & warm (115F?) where the other 3 weren't much more than 75F in a 55F building. The motor can take it, and has for days at a time in the heat of the summer, its not really overheating that much. I am more concerned with the life of the capacitors in the drive since its running at set current 100% of the time. My lifetime specialty was electronics, troubleshooting to the bad part level, and making a living at it since I was about 15 YO, in tv broadcast the last 45 years. I am a CET, but that doesn't make me anything here but a hobbyist now into his dotage years. :) A retired JOAT who uses this stuff to keep him out of the bars is one way I could be described. :) These guys here on this list, and on IRC continually amaze me by bailing me out when I am out on a limb and sawing it off behind me, so I try to return the favor when I can.
