I recently finished building my xxl. I’ve downloaded the universal g code software and watched the instructional video several times. I plugged in the control box along with the computer and am not able to get the xxl to function. I don’t know if it’s an electrical issue or a computer program issue. The program shows I’m connected but I can not change the values xy step or the z step size or the feed rate. (Which should be 10, 4, 9000 respectively) I’m not sure if the fan on the control box should always run but it does not run when I plug the control box into a power source. I followed all the instructions in the build process to a T including not connecting the motors to the control box until all the build was complete, including the rack and pinion rails being positioned correctly. Since there are no lights or any other indicators that the box is receiving power how can I identify the problem? I have no problems taking the control box apart and checking the connections I just don’t want to void any warranty or go there if it’s a software issue. Thanks in advance for any information I receive! Jerry

The fan should run when the box is plugged in. The motors should also lock up when the box is powered and the motors are connected. They will also warm up. If you can move the gantry, the motors are not being powered. Make sure the E-stop button is not engaged. Turn it clockwise to reset the switch.
The Boards get power directly from the USB cord so it is possible to connect to the boards and not be able to move the machine.
Let me know what you find. You can also email me at support@millrightcnc.com.

Thanks! That fixed the power issue! Now when I try to home the machine it thinks the y axis homing switch is in the front of the machine instead of the right rear corner (if I’m facing the machine) I only had a minute to run out and mess with it so I’ll watch the video again and see if I missed anything. Thanks so much for the info! Those are the type of fixes I like😊.

Also there is not a step down window for the xy axis. Only a window that says step size and one that says feed rate. Thanks

Check the direction of your axis while jogging. Y+ should move to the rear, Y- to the front, X+ to the right, X- to the left, Z+ up and Z- down. If your Y is moving forward on Y+ then it if likely that your Y motors need to be switched where they plug into the electronics box. That should fix the jogging and the search direction for the Y Homing. If Y is moving in the correct direction during jogging, you will have to change the homing search direction.
Go to machine>setup wizard.
Click next until you get to the section talking about homing direction for the machine. You should be able to reverse the Y. Hit Next until you get to the end then hit finish.

That fixed the Y axis homing problem. Thanks so much! You have been great!

If I have tool paths that require different bits do I have to change the code for the zeroing macro with each bit? Or is there a better way of doing that. Thanks!

Hey,
I know we talked earlier on the phone. I will include the info here.
Once you set your first bit with the macro and touch plate, the XY will not need to be changed for the next bit. You will change the bit and the find the tool height. Move the bit over the place, attach the clip and in the command line of the console window type -
g38.2 z-50 f100 for mm and g38.2 z-3 f4 for inches. After the probe is done you will type -
g92 z12 for mm and g92 z0.472 for inches.
You can put the two lines of code into a macro separated by a semicolon.
For a bit like a v-bit or surfacing bit it is better to find your XY with a straight bit like a 1/4" endmill then switch to the other bit, assuming the same shank size, and finding your Z. This is if using the macro.

Maybe an obvious comment, but don't turn off the power to your Mega V while you're changing bits. With the power on, the stepper motors will lock the X and Y positions while you're changing bits so their zero settings won't be disturbed. If power to the Mega V is is turned off, the torque you apply to loosen and tighten the collet could move the router and disturb your X and Y settings and the G-code sender won't know that, so X and Y zeros will need to be reset -- and if it's precision work that you're doing, resetting to exactly the same zero point may not be easy.

Can I use the mill right touch plate in the center of a project? I have some rounds I want to use but not sure how to zero the machine if I’m not using a corner. Thanks!
