You need to find out what Speedline recomends for lubrication and use it (chain oil and screw shafts). Don't try to be clever or cheap by second sourcing your own concoction. Currently I am using: Tribol for the chain Krytox for the screw shaft

I should read this closer before I post it. It should read "Lead" paste not "Led" paste. This is grease for the screw shaft that brings the rails in/out on the reflow oven.

Hi again Bob, I checked the theta motor coupling and the set screws are definately tight. I noticed that the theta motor drives an snti-backlash gear (nice design) so there is no play there. It appears that the gear drives a slotted shaft which is d

DAX ! You don't need to remove the entire shaft assembly to clean the clutches. You can just drop the top portion of the spline out to get to them. It seems as if you have already taken off several shafts. I would HIGHLY reccomend that you do not

Before risking screwing up the alignment of the frame, and upon the advice of several SMTNET users, I decided to see if I could get away W. just changing the screws. I found screws with 2x the pull strength as Alpha's. But they didn't fit!! The Alph

Don't try the mecha check yet unless you know how. have you checked the coupling shaft of Y-axis? If it's ok, take a look at the ball screw if it looks like being scratched or something unusual. Also, observe the movement of the machine if you hear a
