Investigating motor issues; The motor is a Centroid p/n 3879 17 in/lb 2350 rpm @120 vdc I took he X motor out, spun it by hand no problem. then I shorted the two wire and felt it dragging. I also ran it with 12 vdc and it spins freely. I measured resistance; red to black 1.5 Ohm. Red to gnd open Bla...

Probably should have checked earlier but the X axis fuse was blown and the replacement blew as soon as I powered the board. I will need to start the process of returning the board. This was bought August 2023 what is the warranty period?

It's the one on the board. And I noticed #2 was blinking later. BUT
I checked the X fuse on the board and it was blown. I'm pretty sure I heard the replacement go...poof...yup it blew as soon as I turned on power.
I would think that could be why Z didn't move when the swap happened...

On the ALLIN12DC one of the limit defeat switches is blinking green - specifically #3

UPDATE I swapped encoder on X and Z and still have a problem on X, the encoders are both OK. Troubleshooting servo, ballscrews and ways sounds like the next steps

I am retrofitting a Hardinge CHNC 4 with an ALLIN1DC. Things were going ok until a couple days ago when I started having problems with the X-axis; not sure I can call it oscillation but it will shudder as it tried to move and will error out with a couple different codes 410 & 411, as I recall. A...

Here is the video of the machine https://photos.app.goo.gl/tTHaAoWbbaSFoaM86 it doesn't last long before I get a fault. You can see when it starts as the chuck wrench dances down the parts chute...9-) UPDATED with PID screen shot and the tuning file UPDATE 2 I have the homing set to Jog. I set part ...

For my last try, I used Fusion to generate the tool path and upon closer inspection the default pitch and depth values were very far off and the containment was wrong, making the tool cut into the shoulder. I'm currently having some X axis problems. When I get going again, I will try first with Inte...

OK I will put everything back together today. I have a question about encoder alignment, is it critical to reposition it back to where it was? There is a wide range of adjustment. It sits on a plate, which can rotate - I marked it's position. The encoder has a bracket with a slot that also allows so...

As for cutting into your shoulder, where are you setting your Z0 for the threading tool. Many people start threads by single pointing them and finish with a die. I set Z offset at the spindle side. I will try taking a few passes and finishing with a die.. I've got other issues going on that are roa...
