Re: Major shift in printing
Here is a pic of my connector. 6 pin. How do you know if the two different ends are compatible? How far did you cut back on connector wires
Re: Major shift in printing
The motor end actually uses a 6 pin connector but only uses 4 of the pins. The end on the board is 4 pin.
Re: Major shift in printing
For the one that I cut the bad part out and spliced back together I was lucky enough to find the actually location of the break by connecting a multi-meter to each and then work along the wire flexing and straining it. Slowly stressed a smaller and smaller section of the wire until I narrowed it down to being in about a 2 inch section near the 6 pin end.
The other one (x-axis that I completely replaced), I knew it had an issue but couldn't isolate it. The trouble with just using a multi-meter is that you might always have conductivity even when under strain, but it might still fail when under load.

Re: Major shift in printing
Did you use a new wire harness. For x axis. If so. Did you buy it from xyz?
Re: Major shift in printing
I made a new wire harness with some 24 gauge wire I had around and some JST 2.0 components purchased from DigiKey. Also picked up a PA-09 universal microcrimper from Amazon (~$40).
Re: Major shift in printing
Was the female jst you bought compatible with the one on the x axis motor.
Re: Major shift in printing
Yes, the JST 2.0 PH series connectors are compatible with all the connectors used on the Da Vinci 1.0A board, stepper motors, and sensors. The real pain is getting a good crimp with the crimp on ends because they are so small. That's why I ended up Spending ~$40 for that tool from Amazon.
Re: Major shift in printing
Well after a few hours of investigation I discovered that the blue wire that connecst to the x axis motor has a break in it that doesn't always loose contact. Used an Ohm meter and connected it to the cable connected to motherboard and the other end that connects to motor. placed meter to each colored wire then I moved the x axis manually and watched meter values. all colors except blue wire showed were good. Blue wire would show open at various locations. Mostly when the x axis was all the way forward. This is when there is the most flex on the cable harness. I believe the break is near the cable tie they used to connect harness before the connection to motor. Does my theory sound correct? Plan on splicing blue wire a couple of inches before cable tie to just after tie. I hope I'm correct.

Sounds plausible. Could surely cause your issue.
Printing since 2009 and still love it!

Re: Major shift in printing
That is how you determind your problem. Correct?
Re: Major shift in printing
Sounds like you're on the right track.
Re: Major shift in printing
Fixed blue wire that connects x axis motor to motherboard. Found where cable was broken and spliced new piece Where cable tie connected to motor. Cable tie must have damaged wire over time. Have 100hrs of print time. Easy fix when you know what to look for. Hope this helps anyone experiences same problem.

Just the female end.
Thanks
That is the correct style but I believe the motors use 5 pin connectors with only 4 wires. I did not redo that end when I converted.
My motor is a 6 pin with four wires.
