Finally able to get the machine to the garage! On a temporary table as I intended to go full 4x8 sheet but likely have 40x40 workable as-is so I can at least start on a workflow.
One question, one of the couplers looks a little more open than I was expecting. I suspect this is from my initial running of the machine when I didn’t realize I had the wires in backwards, kept hitting to raise Z and I believe it was lowering it. Does this require fixing or am I OK to continue as is?
I ended up replacing mine when I bent mine in transit. I suspect that you could use it but that it would be hard to square your z as the tensions would be different.
Try printing a pair of of these from @anttix:
To protect your next set.
The two things I would care about are:
If those two things are good, then I wouldn’t rush to replace them. But probably order some spares on the slow boat.
I am still running some fairly badly battered couplers inside of these plastic shells. I dismounted them after the “incident” and used two pairs of small needle nose pliers to press the “spring” part back together, coil by coil.
Needless to say I have spares, somewhere …
These “spring” couplers are really not precision parts to begin with so as long as they don’t slip or twist under torque, they’re fine.
@Mcunn will make sure to print this for the next set!
@jeffeb3 yep, everything checks out so I think I’ll order a spare set to have on hand.
@anttix Thanks! Seems like I should be OK for a bit but will order, and likely lose, a set of spares
These snap around the coupler from the sides so they can be installed even without taking the couplers off the machine. You may need to loosen set-screws on one end to be able to compress them enough to fit though.
