@real1st Cool that I'm helping a fellow Canadian but also a fellow Ontarian! I'm in Cornwall, a 1-hour drive to Ottawa. Please post your Milo build in our build section when you get it started. We love to follow along. Is it an LDO kit? What are your plans for the electronics? Jake England has put together an electronic box, an alternative to stuffing the electronics under the Milo.

I am in Brampton.. West end.  Plans for it?  Nothing crazy.  It interested me.. Problem is I have 7 projects Im supposed to be doing.  I have never been a fan of stuffing stuff under anything, voron included, thats another one of my many projects, I have a 500x500x500 voron 2.4 that I need to clean up and redo the gantry.. so much to do.. thankfully I have all summer..

That's great, not dumb, this is how you learn!

Hey.. So I have the machine functionally working..  x, y, z, etc.  Endstops all work..  wiring is cleaned up to the back, good enough for some testing..

 

I have NO experience really, I have a shapeoko but rarely used it, everyone else did.

 

Looking for find software that will let me generate the gcode, sicne the other machines are all connected to a desktop, while the scylla is wireless and I just upload gcode.

 

Any tips?  Anything that is useful?  Carbide Create was one I used a bit.

[PFarm]

Glad to hear you got the machine working. I'm using Fusion 360 free version, but the drawback is that the tool changes require generating gcode for every tool change. In this example, there are 5 tool changes.

Okay so I am trying to fine tune my settings..  

My official work area on my cnc are:  X 335  Y 365

I adjusted LIMITS.G and put those.. but Y is showing 400 still..

Did you do m999 (firmware reset) to see those changes? Again, any changes you make to a G file should be made in user-config.g, so if you update the RRF the changes won't get overwritten.

Yes. I did. M9999 not M999 though.

M9999? That is not a RRF command.

Okay weird...  Let's try this again.

[real1st]

Okay that fixed it.. My bad..

[real1st]

I am now getting this:

But it says correct Y number.

By the way M9999 reload Millennum OS.

Okay.  So I cleared those warnings, and homed, they did not come up again.

[real1st]

Okay so I want to do a dry run kind of thing, no router installed. Just to test the movement of everything.

I tried using openbuilds cam, setup a basic spoilboard, and uploaded the gcode..  immediately got an error saying:

[real1st]

This is the gcode

[real1st]

I would assume I am not setting up the cam thing properly for my machine, which is causing the issue

 

[real1st]

My machine when fully homed, shows this on the dashboard.

 

[real1st]

I even tried setting the z, since I dont have a probe setup yet..  Just wantd to do a quick test

Only one end stop required for the y axis to trip both steppers as PFarm mentioned.

i have my y axis motors at the front purely for ease of maintenance so will post my estop code for you tomorrow.

You need to work out your minima and maxima travel on all 3 axis also input this at the same time

so you will need to reverse your y axis directions in the code I post tomorrow if I understand correctly 

Hey buddy, I could really use your help with your CAM setup...  Since we have similar setup, would be easier.  I am thinking I need to do something with my config files/cam setup.  Really could use your help on this..

[real1st]

So I have it running, now, I had to set the z (just used paper method).  From there it runs now.. 

[real1st]

Okay so I have done a couple tests... fixed an issue there and here.. but right now I am using EASEL just because its fast..

 

I noticed though because my Y endstops at the front, my XY intersect at 0 and 365.  Instead of 0,0.  So as a result my projects come out inverted.  Is there a way to fix that?  so when the Y endstops it is at 0.  and when it moves backwards, it is positive increments intsead of negative?

Hey sure no problem,

Can you post your "User config" file in its entirety and I will see what needs tweeking.

Apologies for the long time away ironically since getting mine up and running theres been one thing or another stopping me from getting stuck in.

 

Cheers

Just to add when it homes which corner does it go to front right ?
