Got first run today , a little ? tho..

Your end switch for z-axis has to be set to zero. All of your working space is in negative values.

I can give you my 420 settings if you want.

Hey

Looking on it now,, in softlimits i have..

Z: softmax=130,, softlim=0,, homeoff=130,,

Right. This is possibly wrong. Try max=0mm, min=-130mm, home=0mm

BR,
Ronald

Yes, thx, do you have x and y to?

I mess around,,, the fix on Y worked 🙂 Now Z goes up,,

Sadly i forgot to take a picture of the settings before i tryed other settings, and soft llilimts wont work now...

If some of you will post a picture of Mach3 Softlilimts screen would be help full 🙂

Got most work now,,, only thing is that ater job finish it goes to left front, i want it to go left back?

But if i change Home offset from 418 to 0 i get a Softlimit error.

This is due to the strange G28 code. I also didn´t succeed to get it to the other end. It always goes to x=0, y=0, z=0 at the end of every job. Please find attached the settings of my 420/2. If you succeed to change the G28 code in your post processor to get the machine to x=0, y=420 and z=0 at the end of every job, I would really appreciate when you could tell me how to do it.

Best regards,
Ronald

G28 only tell to gotot machine 0.0.0 as i know,, the strange thing for me is cant get Mach3 offset/Softlimits to accept Y=0 is left back corner 🙂

Oh, you´re totally right. I never thought about this problem this way, but we can also do it this way. We are totally free to choose the origin of our machine coordinate system. Actually, I have the following settings.

X-Axis: Soft Max=295.5mm, Soft Min=0mm, Home Off.=0mm
Y-Axis: Soft Max=418mm, Soft Min=0mm, Home Off.=418mm
Z-Axis: Soft Max=0mm, Soft Min=-138mm, Home Off.=0mm

If we want the machine to go to the upper left corner, when going to zero, we have to tell Mach3 that all the end switches are at zero position. In my case, the settings must be the following ones (not tested yet):

X-Axis: Soft Max=295.5mm, Soft Min=0mm, Home Off.=0mm
Y-Axis: Soft Max=0mm, Soft Min=-418mm, Home Off.=0mm
Z-Axis: Soft Max=0mm, Soft Min=-138mm, Home Off.=0mm

So you only have to set the home position for the Y-Axis and the Soft Max for the Y-Axis to zero and the Soft Min to -418mm or what ever you actually have at Soft Max.

Give it a try and let me know the results.

I will test it tomorrow.

Best regards,
Ronald

Thx i will test that 🙂

Did you already test it?

BR,
Ronald

Hello,, no not yet, havend had the machine started yet, had a busy week 🙂

So i testet some...

X= max=299,0,,,,,Min=0,0,,,,,,,Off=0,0
y= max=418,0,,,,,Min=0,0,,,,,,,Off=418,0
X= max=130,0,,,,,Min=0,0,,,,,,,Off=130,0

Homing and soft endstop and slowdown zone works great..

If i put in G28=0 it goes down to the bed..

If i reverse Y ---Max=0,0 Min=-130 Off=130 then G28=0 works, it goes up
But then Softlimits give me warning and wont run..

You don't want the machine to go down after a job. That's dangerous for workpiece and mill.
If you want the machine to go to the upper left corner in the back all home switches must be zero.

Try the following settings.

X= max=299,0,,,,,Min=0,0,,,,,,,Off=0,0
y= max=0,,,,,Min=-418,,,,,,,Off=0
Z= max=0,,,,,Min=-130,,,,,,,Off=0
