General Mach Discussion / Problems with my probe???
« on: January 21, 2017, 06:51:09 PM »
I'm building a Joe's CNC EVO and have the machine up and running. With the three axis calibrated and running very smooth. But there is a glitch in the probe. I can see the probe light come on and run the probing script like it should, if I hold the probe plate in my hand. If I put the plate down on the work piece, Z goes down and touches the probe plate, the green light comes on and the script stops, the probe light will stay on and the Z will not retract. Then I have to unplug the probe plate in order to get control of the cnc again. I have checked all of the connections on the C-10 BOB. Here is something I've noticed when the probe light is on, pin 1 on the BOB comes on to a relay for the 12v to the spindle cooling pump. Also sometimes the Z stepper will move one or two steps. ???
For a little history, this is my second DIY CNC but I never had problems like this with my probing script. The screenset I'm using is 2010 Screenset.
I have a 104 capacitor on the pins going to the probe.

ger,
I'm not sure what's going on. I opened a new Mach3 with no settings and reset ports & pins, and motor tuning. Everything started working ??? ???

Thank Naijin,
I'm getting close to making chips. Just need for Mach3 to work right..............:(

General Mach Discussion / Will not zero machine coordinates

My Mach3 has started a new problem. It will not let me "Ref All Home" to zero in the machine coordinates. Is there a setting I should check. I had it working but I'm setting up a new Joe's EVO and the ref all home stopped working.

Well I found my problem. Bad soldering on a DB9 connector. Replaced DB9 connector with a new one . Now everything on  the Z axis is smooth and quiet!

Knock on wood but I knew that this build was going to smooth and that something had to go wrong. >:D >:D  Up tell now every thing has gone together without a single problem.  ::) ::)

Naijin:
Thanks, I looked at all of that while I was trouble shooting. The only thing I could come up with is the stepper it's self. Like I said I changed the cables with one of the other steppers and the Z stepper motor still would not run correctly going up or down using a different cables and driver. You'd think if the problem were at the driver, cable or BOB that the other stepper motor (Y axis) would show the same symptoms as the Z axis if the cables were reversed. I hope I'm making myself clear about switching the cables between the two stepper motors.
Thank for trying help.

These were all new out of the box NEMA23 570 oz-in steppers so you would thing that they would be good to go. After I removed the Z stepper motor I can tell by turning the shaft by hand that the motor has a problem. There is a drag part of the way around turning the shaft. Most of the 360 turn it turns easy then it gets harder to turn for about a quarter of the way.

Addendum:
This morning I did some more trouble shooting of my new Joe’s EVO CNC. I’m sure that the problem is in one of the NEMA23 stepper motors on the Z axis. I changed the cable from the driver of the Z axis motor with the Y axis motor. This drives the Y axis smooth but the Z axis motor will not work as it should. (See the above description) I notice also that the Z axis motor is noisy and will not run smooth at all. The other three motors make all most no noise at all.
This is what I told the company that I bought the 4-Axis NEMA23 CNC Kit from: >:(
I am a little unhappy with these parts I received from ******* ********* ***. First the 5 volt transformer had to be returned and I had to pay the shipping just to get a $10.21 refund to my PayPal account. I lost money on that deal. Now it looks like I will have to pay return shipping to return a defective NEMA23 stepper motor. More money lost. Next time I think I’ll look for my parts on Ebay.
