Hopefully once I get everything set up I’ll stop almost spamming the forum here, but:
As updated in the other thread, I finally got z axis square, replaced the pinion gears, and started setting up calipers to tune counts per unit.
Turned everything off last night and it was working.
Today, turned everything on, hit home xyz - z axis just makes a grinding noise and y axis induction sensors just crash right into the stops.
Again, everything was working last night.
Since this is brand new and I haven’t really changed anything, I thought maybe when I was looking through screens last night at motors, axis mapping, etc I may have changed something inadvertently. I did a quick uninstall/reinstall and loaded the avid profile/configuration from scratch.
Same problem.
I’ve double checked that I have the right motors selected, spindle selected, etc.
Seems like support is already out for the holiday - any help would be appreciated!
Ok - update #1 - Z axis seems to be mechanically hosed.
I took everything off the front, unplugged the z motor, and I can’t move the z at all - either through turning the coupler at the top or by pushing up on it.
I’m not sure why the y axis would crash on homing at the very same time - maybe just a coincidence?
Since you just replaced the pinion gears I would take a look at that work.
Then I would grab the gantry (power off) and move it around by hand. Then I would power on and try to move the gantry and see if there was any movement that shouldn’t be there. Doing that might give me the confidence to say it isn’t a mechanical issue.
Next I would check for loose connections on the sensors and the motors.
Next I would try to manually activate the sensors (never tried it but I suspect if you wave a bolt in front of them they should detect it).
If the sensors are working and the Y axis is not playing correctly I would wonder about if the y1/y2 stuff got flipped. Note that if you moved the cable tray to the left side things are different than if the cable tray is on the right side.
Appreciate the response - all connections look good, cables are good, passes the ‘test’ of passing a wrench in front of the sensors and the correct ones show up as triggered in mach4. Just not sure why they worked, nothing changed, and they crashed. Sort of scared to try it again (assuming I can get my Z unstuck).
Also, on the Z, it’s the dumbest problem ever - I had the brake clicking thing, and I found the pdf Avid put out and ordered and used the loctite (509?) that they suggested. I think it got down to the ball screw itself and now it’s seized. I’m going to blast it with a heat gun and see if I can break that bond and get it moving again.
Take it slow, and if you aren’t sure double check/ask.
I have a rule that after I make one mistake I take a break/quit for the night. This lets me have time to think before I cause cascading problems trying to fix things that I don’t understand.
