I do like the knee because it has like 15in. of travel. One 1780oz.in. motor would move the knee with a 2-1 gearing, but that was all it would do. I've gotta try to put another stepper on it, Stack or 3 pulley set up just to see. I've never got the torque curve for these motors yet. That will help me make a decision.

Oh yea, I saw those pics. I want to see that 5 axis monster run. You do good work. I'll have to keep an eye on you. Thanks for the link, I will check it out.

Tell us more about your setup. What is it on? Is it a retro? I don't have those boards but I would think all breakout boards would be set up the same. Go into config., ports and pins.. Do you have a straight through cable. (Not a printer cable) Do you have power hooked to your board?

Those should be in your screen set. The default is 1024 for a mill.(I think)

Hello,
    I'm not sure what all you have to reset. I think it depends on what version you have and what version your upgrading to. I'm pretty sure if you go from Mach2 to Mach3 you have to reset everything. I think if you are going from an older Mach3 to a newer Mach3 all you have to do is save your xml files to the new one. Please don't take my word for it though. Some of the guys with more knowledge will let you know.
    Have you tried doing a search on this?

Hood,
    It's the Mach. What can I say, he's in love!!!!!!  He's changed so much since he meet Mach. They are  just dancing around, all the time, doing frivolous things. Maybe the infatuation will wear off one day and they can put their heads together and do something productive. They sure are having allot of fun now though. I'm pretty sure this is going to be a long lasting love!!!!!

   Yes, the knee is heavy enough to remove any backlash it may have had. No drift,no counter weights, no break and no d_ _ _  speed. 8 in. minute is all I can get on the knee, 130+ on the x and y. I don't think this will be to big a problem though, most stuff I'll be cutting will have a low feed anyway. Spindle is to slow to feed too fast.I'm using 1780 oz.in. steppers on all three axis. The finial drive for the knee is 6-1.  I replaced the lead screw and nut, with high precision ones. I also replaced all the bearings and gears. It is pretty tight. I have .0015 backlash in the knee, .0015 in the y, and .002 in the x.

General Mach Discussion / Battery Backup?

« on: October 09, 2006, 07:03:16 PM »

Does anyone see a problem with me using a battery backup for my control PC. It'll probably be an APC. I think APC power chute will have to run in the background for it to work as it should.

Here are some pics of my little Frankenstein. Not much, but I sure do love it being controlled by Mach.
