I’m in the process of getting my crossfire up and going. The first sign of trouble has bared it’s face, the set screws attaching the Y axis lead screw worked lose.
Fixed that and then the X axis tossed it’s lead screw set screws to parts unknown.
End of first experience, need to go to Abba Bolt and buy a box of set screws…
Btw I COULDN’T get through the breakin before the screws left for parts unknown.
And please don’t tell me I didn’t tighten them enough, any tighter and I would have broke the head where the allen wrench connects.
The lead screws have a monster chamfer on each end, nearly a point, this doesn’t help the set screw problem.
Suggestion. Leave the leave the ends of the lead screws square with a .015 edge break, don’t set the screws in the threads, put a whistle stop flat on it. That is a flat that has a slight back taper, that pulls the lead screw in, one flat for motor end, 2 on the support end.
Better yet would be make compression type lead screw attach couplings.
My first experience with “Fire Control” hasn’t been the best either, if I leave the plot on I get a general protection fault and a stack dump. The software itself I’m finding very minimal, first impression, you should have stayed with the Mach products.
In case you are wondering if I should be so audacious to criticize the software, I spend my days programming 5 axis mills with Siemens NX, I know a smidgen about controls.
Fred, I look forward to your reply.
