MiKro Posted January 25, 2018 Author Report Share Posted January 25, 2018 Not a happy camper at the moment. I put the stepper on the Zaxis and dammit it is binding somewhere? I keep getting resonance stalls from binding. I have it torn down again. trying my best to find the bind? I think my ball screw is not parallel to the rails by ever so little of an RCH. Fuck ME!!! MK update: found it. all appears okay now. had a ball screw bearing that was binding Quote Link to comment Share on other sites More sharing options...
curtisa Posted January 25, 2018 Report Share Posted January 25, 2018 So was it a resonance stall or physical interference? Quote Link to comment Share on other sites More sharing options...

As you know sometimes it takes so little to make it go into mid-band resonance. Basically I had an end bearing that had not seated properly which was binding the ball screw. That's why I felt it was the ball screw appeared to off parallel. LOL!! It now runs@ 300ipm with zero issues. I will push it up more tomorrow. See if I can get 500IPM not that I need it. Time for a scotch. Quote Link to comment Share on other sites More sharing options...

MiKro Posted February 6, 2018 Author Report Share Posted February 6, 2018 OKay here is a quick vid of X, Y and Z axis testing XYZ Test Video Quote Link to comment Share on other sites More sharing options...
MiKro Posted March 6, 2018 Author Report Share Posted March 6, 2018 I had a set back yesterday. While squaring up the x and y axis my z axis power connector smoked itself. It is rated at 5 amps. Even at idle it is drawing some amps due to the weight of the z axis. I suspect that this led to overheating of the avionics style connector and melted it inside causing a short. So back to the drawing board. I will change these out to EC3 connectors used for HIGH discharge lipos in the RC sector, as they are rated at 15amps and 30amp instantaneous. No they wont look as nice but I don't want to worry about when another connector fails. MK Quote Link to comment Share on other sites More sharing options...

MiKro Posted March 9, 2018 Author Report Share Posted March 9, 2018 Got my new connectors in today. Now the task of redoing everything starts. GRRRRRRR!!!!! MK Quote Link to comment Share on other sites More sharing options...
MiKro Posted March 10, 2018 Author Report Share Posted March 10, 2018 Got the connectors done, Now back to squaring up X,Y I'm within 0.0005 at this point square in 3 inches. I'm 0.0005 " off parallel on the X in 3 inches. and same perpendicular to X in Y Sounds close but still not good enough. That comes out to 0.0033 in 20 inches.. LOL!! I think I can get it closer?

MiKro Posted March 12, 2018 Author Report Share Posted March 12, 2018 While waiting on my new test indicator, I have been tramming the spindle. I use a certified granite slab to do this. Once it is level to within 0.000" corner to corner. it's 12"x 9"x 2". I then start the tramming process. Currently it is 0.000" in Y in 5" and 0.002" in X in 5 inches. I am tired and will continue Tuesday to dial X in to 0.000" MK Quote Link to comment Share on other sites More sharing options...
MiKro Posted March 13, 2018 Author Report Share Posted March 13, 2018 Okay done with preliminary tramming and square. Tramming 0.0003" in 5 inches in X and 0.0002" Y I can live with this. X parallel 0.0000 in 3" I'm really good with that. Y perpendicular to X 0.00025" in 3" I'm very happy with that. That's 0.0016" in 20" I'm sure once I get the bed on it ,these will need to have some small adjustment again. Time to move forward with machine bed and other electrical aspects.

MiKro Posted March 17, 2018 Author Report Share Posted March 17, 2018 So, I got the bed on and yes there was some movement. So now to reset everything again. The difference is it is only off by a few thousandths, so pretty easy to fix. Hopefully Sunday I will have that all done and the spindle power wired. MK edited to add: Tramming and square done again, better than before. Spindle power is operational now. Next is to mount vfd and wire to controller for computer control of start/stop and spindle RPM for gcode. Quote Link to comment Share on other sites More sharing options...

F'me I don't want to spend 2 days looking or $75 to replace it , just to find the one I had 2 days later. Dammit!!!!!! MK Quote Link to comment Share on other sites More sharing options...
curtisa Posted March 21, 2018 Report Share Posted March 21, 2018 Have you got any plans for dust control? I've just added a dust shoe to the spindle and it's made a massive difference to the amount of mess. The added bonus is that I don't have to babysit the machine and follow it around all the time holding a vacuum cleaner nozzle. Quote Link to comment Share on other sites More sharing options...
