Z and y axis not working properly for Hello World

Hello all
Just received my SO3 yesterday and finished assembly today. Tried to print the hello world first project. Moved marker to the bottom left corner of paper, jog +z axis to just touch the paper, zero then zero all click done. load program push run.At this time the z axis moves up and the y axis moves towards me and the x axis moves to the right, machine prints in the air, z and y axis is out of position. What have I done wrong.

Mel,

Sorry, but I don’t quite understand your problem, BUT I see that you said you jogged Z+ to touch the paper, and Z+ should be UP, so that part I understand (Z motor is feeding backward) Easy fix.

But first let’s understand about your Y axis. Looking at the machine from in front, Y- is towards you, and Y+ is away from you. What way does your Y feed?

Next, the X Axis. Correct direction should be: X+ To the right, X- to the left (Again, looking at the machine from in front)

Awaiting your reply.

Rich

Thanks for the quick reply Rich. My Y+ moves forward or towards me and the Z+ moves down. I am using Carbide Motion. Guess I have to go into the GRBL and change a couple of parameters. Not sure how to do this. Can I do it in Carbide Motion and settings.

Mel

You didn’t talk about your X Axis, so I’ll assume that it is correct.

First let’s talk about your Y.

The controller board had 2 Y plugs. Can you reverse the Y1 and Y2 plugs, and tell me if that fixed the Y direction?

I had the same problem. Your z and y axis are reversed. Here’s the link to fix it. The real questions is way are they coming out of the factory like this. Seems to be the standard.

@Merv100 - The other suggestions above are good and worth investigating. With Y-axis, Rich is right you may have Y1 and Y2 swapped on the board. But since you said your Z-axis is going the reverse direction it sounds like an issue I had recently. Two of the little wires within a gray wire hardness (each has 4 wires inside) were out of order at the point where they plugged into the white connector. I was able to reverse them and all was good. This at least gives you one more idea to try as you’re troubleshooting.

Good luck

Hi Rich
I changed my Y1 and Y2 and that fixed the direction. I tried to fix my direction on the Z axis using
/#3=4 got an error (grbl error - expected command letter ) then tried #3=4 and got an error ( midi error: syntax error )
I copied my current settings

Use $3=4

Not #3=4

I’m glad you switched the wires to the correct position rather than changing the bit. Let’s do it the right way.

Rich
I entered $3=4 then send but the z axis is still reversed, do I have to save the new settings, if so how

They save automatically.

Can you show me another $$ settings page? I want to see your $3 setting.

Typed in $$ and send but does not show settings. The midi page says to first enter / to send directly

Is this the page you want to see

Almost, where is the information to the right?

See my example: (Photo 2)

Edit (Add) You are showing me that your machine had a $3 =6, which is Y AND Z inverse. The machine does not ship this way from Carbide, so I am a little confused as to who changed it?

See Photo 2 also

Is this the log file. my log count is up to 895 and keeps counting. this is a copy

<Idle,MPos:0.000,0.000,-4.000,WPos:0.000,0.000,-4.000,Buf:0,RX:0,Ln:0,F:0.>

Should I clear it first

Where is this copy you speak of?

And I added some information to my last comment, can you talk a little about the $6 setting?

<Idle,MPos:0.000,0.000,-4.000,WPos:0.000,0.000,-4.000,Buf:0,RX:0,Ln:0,F:0.>

The count is now up to 3300. For some reason when I paste the copy it does not show this
Mpos:0.000.0.000-4.000.WPos:0.000.-4.000.Buf:0.RX:0.Ln.F:0

I did try this one time /$3=4 and it reversed my Y axis again so I changed the Y1 and Y2 plugs I re entered the $3=4 again

Mel,

You don’t have to clear anything…ignore the test count, but please (a) answer my question and please provide me with another screen shot with the information to the right as my photo.

WHY are you adding the slash (/)???

All the log shows me is the count increasing and the test waiting and then the Mpos line

You can scroll the LOG Screen to see the $$ information if it went past.
