Derek,

I'm in the UGS Platform. Everything to this point appears to be working. When I connect and reconnect, the console streams lots of codes and at the end, It shows I'm connected.

I did see the $20 = 0 (Soft limits enable, boolean) was set at "1".  I changed settings $20 = 0.

Reference Assy Instructions Page 32 (to make some jogs on the machine.)

Click the socket icon that is to the right of the baud rate. It will turn from red to green, indicating that a connection has been made. We will now make some jogs on the machine. Set your steps/mm settings to what you see in the picture below. It’s very important that we start with just 1 millimeter steps at first. We’ll use these small steps to see if something is backwards or crossed up. Press the Z+ button in the job screen shown below. We are expecting the Z axis to move up 1mm. If it moves the opposite direction, make a note of it. Once power is turned off (and only when power is off and has been off for 60 seconds) you’ll need to flip the Z axis motor plug 180 degrees if it moves backwards. Now press X+. We are expecting the X axis to move to the right when viewed from the front of the machine. If not, make a note so the X plug can be flipped around. Now press Y+. We want to see the gantry move towards the back frame on both sides. Pay special attention to whether one motor is turning opposite the other. If one or both Y motors is driving its side towards the front frame when you press the Y+ button, make a note so you can flip the plug on that particular motor. If necessary, remove the power plug from the wall and the USB cable from your computer, wait 60 seconds, and flip relevant motor plugs if any motor was travelling opposite the intended direction.

When I click Z+, Z axis motor hummms.

When I click X+, X axis motor hummms.

When I click Y+, Y axis motor hummms....

I did this many times and tried changing feed and steps in mm to 10, 20 to 50 etc...

So, in the back of instructions, I found this reference when machine isn't moving.

Reference: Troubleshooting Addendum

Problem: The machine isn’t moving to the commanded position.
Solution: Most often this happens when incremental positioning is set (G91) but the user thinks the machine is in absolute positioning (G90). Set the appropriate mode.

I tried changing G90 to G91 but UGS platform but this would give me an error and the Alarm message showed up... and it would not let me change G90 to G91

I could not get out of error unless I disconnected and exited UGS platform.

I then would restart UGS platform. set “Grbl”, baud =115200 and set the second USB connection to COM6.  I'm not sure but something maybe going on with first USB connection it usually only shows COM3 and not COM6.  I believe second USB connection to COM6, makes light on UNO board to blink.

When I hit connect,  it streams code settings through the console then tells me that it is connected.

Then I try jogging X, Y, and Z and only get the humming of the motors.

Updated 51 minutes later by skale:

I did some on-line reading and I guess I do not need to change Soft limits $20. When I get home I will set $20 = "1". I do not believe this will fix my no movement problem.

What do you suggest and also using UGS 2.0 Platform (Nightly Build, screens appear different) what's the best way to reset machine if my values entered are too high or requested moves are out of range and to reset alarm.

I wondering if this is my problem, since I have the homing switches.

If you have homing switches, the machine will also prompt you with [‘$H’|’$X’ to Home]. Click on the commands tab at the top and type in $X then press enter. This will unlock the machine to allow motion commands. Alternatively, you could type $H then press enter. This will initiate a homing cycle.

?

I honestly don't understand what you are experiencing with g90 vs g91. I've never seen that in UGS.

The soft limit change will not affect the no movement situation. Please don't change any settings from defaults. It will only make things harder to diagnose.

Did we set up your electronics for you here?

[skale]

To assist in troubleshooting, I want to provide the following information to help solve my dilemma.

Ref. text from Monday night, to change $21=0. I have not had a chance to change yet.  I will be out for a few days and can give you an update on my return.

I did try $X last weekend but it did not turn off alarm but I guess that may be because Hard Limits were then set to "1". The X, Y, and Z values on the Alarm window, would not clear.

This is the picture I texted, Monday and you replied Hard Limits should not be enabled.  Please type in $21=0 in the command FYI...line and $X will turn off the alarm.  So I am hoping by clearing the alarm, I will be able to get movement on CNC.

Additionally, I changed setting reference page 37-38 Grbl Settings Appendix: and made to match.  But, I missed the comment: "Hard limits are not recommended unless you take some additional electrical noise precautions." 

Also, I know I have tried the Home reset buttons in UGS.  Would that cause a problem?

If I change $21=0, and enter $X, then try jogging X, Y, Z axis.  If I do not get any movement can I send you a picture or file to help troubleshoot?

[Derek the Admin]

If you don't get any movement after that I'd suggest checking everything from square one. If I remember correctly, we set up your electronics boards should be good in respect to that. It's then a matter of checking and rechecking all those things you assume were okay: IE: The power supply is connected correctly. There is 24V at the screw terminals. Every setting matches the factory settings, etc.

[skale]

Good news:  Some progress....

I reset $G21=0

also entered $Xl

Y axis moves when I jog Y axis

Z axis moves when I jog Z axis

X axis humms each time when I jog X but no movement.

Any suggestions???  getting closer......


Also, is there a way copy and paste text from UGS to this reply and a picture from an iPhone to this reply while in a laptop.

UPDATED POST 7/15/2019 1:00 PM:  TRYING TO SOLVE PROBLEM WITH X AXIS FOR NO MOVEMENT....................

1.  I GUESS FOR A TEST, I WILL SWITCH THE WIRES GOING TO THE RED BOARD.  I'm going to switch connection between Z axis and X axis to try to isolated problem and to determine if problem is at the motor.

2. If I get no movement now on the Z axis because of switching wires, I will check voltage on purple board for Z axis.  If voltage is off, I will correct voltage.  If I cannot correct voltage, I will swap out purple board....

Not sure what to try if this does not work.....

UPDATED POST 7/15/2019 7:40 PM:  No movement with X axis only,  Z and Y axis are good.

1.  I switched wires to motors for X and Z.  The X axis motor checked OK.

2.  I checked voltage on X axis purple board.  Voltage check .64-.65

3.  I reseated purple board.  Still no movement with X axis.

Pic show error msg: An error was detected while sending '$J=G21G91X2F600' (error:15) Jog target exceeds machine travel.  Jog command has been ignored.  Streaming has been paused.

Current position of X axis is approx. in the middle of work area.  no movement in the -X and I get error above if I jog once in the +X axis.

I think but not sure, that some how machine thinks I have exceeded to X axis limits.

When I had no movement with Z axis, I increase the steps in Z from .6 to 6.  I could then see the Z axis move but this is not true for X axis.

You can email yourself the photo from your phone and then open the email from your laptop, then paste it into your reply on this forum.

[skale]

Thanks,

I try not to use my email on a laptop due to spam. I use email on iPhone 99.9% of the time. I just tried to save a pic to drop box. I thought there is a way from the cloud and then paste a link in the reply. Do you know what I’m talking about.

Thanks for your reply..

[rowiac]

If you have the Dropbox app installed on your iPhone, go to your Photos, select the photo you want, click the rectangle with the upward arrow in the lower left corner, and your options for sharing photos will pop up. Slide the icons to the left until you see "More" and click that. Now more options are available and Dropbox should be there. This should allow you save the actual Photo to Dropbox rather than just a link.

If you have it turned on in Settings, photos will also be automatically saved to your iCloud, which you can access on the laptop at www.icloud.com. I use Google Photos for that instead (even though I hate Google) since it doesn't use up my iCloud backup storage.

You have on soft limits when you shouldn't. Whether it moves or not, the X+ command will trigger a soft limit alarm if they are enabled. You'll need to set setting 20=0 by typing $20=0.


The X driver is either blown or the coupler isn't set on the motor. Does the X max noise?

I suspect if you turn everything off, including removing the USB, and swap in Z driver into the X driver's position you will see movement out of the X. If that's the case, you need to install a spare driver.

[skale]

Thanks Derek for replying.

For clarification for me, I'm hard headed (thick headed)....

I think you are saying to switch X purple module. X purple module = X driver. Is that correct?

I'm at work now, not at home. But currently, $20=1. X-axis (original X motor) had no movement. Yesterday, I switched the wires on the Red board, between Z and X axis. In UGS display X became Z. When I jog Z to move the original X motor I got no movement on X motor. So does that tell me that X motor or X homing switch is the problem.

Also, by switching Z and X axis the original Z motor still works.

So based on the information above, do you want me to switch X purple module (X driver) with Z driver?

I hope you understand this....

[Bruce]

Yes, The purple module is the stepper driver. 👍

[Derek the Admin]

So to clarify, are you saying that when the X is plugged in somewhere else that is known to work it does not move? Does the Z move when plugged into X?

[skale]

Success!!! I have X axis movement. The X axis motor coupler was too loose.

I found this out after removing X motor and connecting wires to the Z stepper drive connection. When I jogged the Z axis the motor turned.

I now have installed the X motor back but additional adjustments to the coupler are needed. It slips, I believe the coupler is not pushed all the way back on the motor shaft and still needs to be tighten. I will make that adjustment.

But I have three new questions:

1. When jogging X, Y, or Z, why do I get the message "Use separate sizes for Z and XY"?

2. Is there a listing of error messages and possible solutions when using the UGS?

3. I am now starting back to assembly instructions (page 33) building the electronics enclosure kit. Currently, I have $20=0 and $21=0. Are these correct?
