My X axis became erratic today, upon checking the 5 pin connector on the driver, it is toast!
I thought I saw a post on this in the past but I cant find it now, I would think Mouser or digikey would have one if I knew the ID number of the connectors involved. Anyone have any information on these?
The connectors on both X and Y drivers are discolored, the two lower pins are the worst, they appear to be a bit small to carry the current required?
Any insight on this would be much appreciated..........
If these are the little green connectors, they are probably copies of the ones that Phoenix Contacts makes. I'm pretty sure the major electronics houses in the US, like Newark, Mouser, Digital, Allied, Carleton-Bates, etc. all sell them. This might be one place to start:
I wound up going to the hobby shop and getting some bullet connectors and replaced the three output connectors to the steppers, got it going but it isnt permanent.
I need to rewire all three axes as they are all in various degrees of degradation, I dont think the connector is heavy enough for how its being used evidently??
The connector itself was bad, the leads are all fine on all three connectors.
So far as I can tell the green contacts on my 10+ year old 1100 are still in good shape. Maybe yours came from a bad batch of clones?
I am wondering if the new series 3 stepper motors draw more current??
I am going to look for plugs and sockets and remove the green connectors and come out of the driver with 3 wires to a plug removed from the driver itself. I thought about replacing the connectors but if all three are in various stages of burning/discoloration I think I need to replace them with something more heavy duty.
Follow up on the connector problem with the Leadshine drivers, I repaired them with insulated push connectors and short lengths of 16 ga wire soldered to the driver board, hopefully this will take care of the problem for good.
This post is for other 1100 series 3 owners, this may not be a common problem, but was for me, the machine is just over 5 years old. Just something you might want to check..............
edit: I cut down the existing connector rather than replace the whole thing, removing the three stepper connections on the X and Y drivers and soldered wire leads in place of them, then installed the push connectors about 2 1/2" from the board. I can still unplug and remove the driver if necessary, I just eliminated the high resistance joints.
The thing I've never understood about those connectors, at least the ones I've seen - they have round pins, but the contact fingers are flat, making for a VERY small contact area. Then there's the cheap tin plating... Just seems like a lousy design to me.
If you want some good bullet-proof connectors, look on EBay for "aviation connectors":
Despite the very low cost, they are fantastic. Waterproof (IP68), gold plated terminals, very secure. I use larger 4-pin ones in my PDBs and ATCs, putting as much as 30A continuous through them, and have had zero problems.
