Can't get the most basic homing to work:

Code: Select all

M26/X
M26/Y
M26/Z

Removed home/limit switches from the wizard to see if I could figure it out. Not sure what's up.

You have simple home set up right now. It is not looking for limit switches in its current configuration.
When it says Machine Not Homed...Press Cycle Start, when you press Cycle Start it should set machine home right where it is.

Can you provide more information about what's going on exactly? Are you saying you can't get the machine to home with SIMPLE home or you can't get the machine to home when limit switches are configured?

You have some inputs configured, some on Ether1616. I would turn all off except EstopOK and DriveOK and retest, then enable them one at a time.
The last part of your report looked OK.

DriveOk IS INP5
EStopOk IS INP8
CycleStart2 IS INP33
FeedHold2 IS INP34
CycleCancel2 IS INP35
ToolCheck2 IS INP36
ToolUnclampButton IS INP43
LubeOk IS INP47
AirPressureLowMessage IS INP48

I can disable the inputs when I get to the shop tonight. I had commissioned the inputs that are currently enabled, and then decided to connected the X and Y motors.

When I hit home it interrupts and says something like cancelled by user (don’t recall exactly) and the DRO’s don’t zero. When I hit cycle start it says it’s not homed.

When I install a control, I install it as tested on the bench. (Meaning you should have been able to do a simple home on the bench)
Estop button was already wired on the bench and tested. I permanently mount the Estop button on the machine and wire it in.
Wire in power. Power up the control, it should be just as it was on the bench. You should be able to simple home it.
Then, if applicable, I wire in the limit switches. Open the diagnostic screen and test each switch manually and verify it is functioning properly.
Then configure them in CNC12. Test them.

So basically, I slowly add one subsystem at a time and test each one. I don't move on until that subsystem is successful.

My suggestion is you use the All in One DC Installation manual as a process guide. Obviously things specific to All in One DC do not apply, but the step by step process does.(We are going to work on a similar basic Acorn Installation manual soon. We recognize it is needed) All in One DC Installation manual can be found here for reference only: https://www.centroidcnc.com/downloads/c ... manual.pdf

Turn off all the unneeded inputs and get your machine basically setup, Then add one input at a time and test.

Report back. Sounds like you had a long night. But jogging axis around with VCP is a huge success...

Thank you so much, Marty! I sorted out what the deal is.. the external Cycle Cancel pushbutton is a NC switch. I had it inverted in the setup. Now it does simple home. I verified this by holding in the external Cycle Cancel pushbutton and pressing Home All. It homed just fine.

On to the next

Awesome!

The table movement vs tool movement thing is kicking my butt. Coming from a gantry router.. I've watched Marty's two videos and I am still not clear.. I also see the page in the manual. How is the mill supposed to be setup with regard to which direction the table is supposed to move when the X+/-, Y+/- is pressed? Seriously kicking my arse, especially when you throw in the limit switch plus and minus into the mix.

I know my issue is I don't know which way is what and relative to what.. Speaking in terms of table movement currently seems like it would make the most sense. I've watched videos, read the CNC12 and Allin1DC manuals.. Still confused. I appreciate any clarity on this.

Z+ up
X- table all the way to the right
Y- table all the way back

Most guys home y all the way forward Y+

What does forward/back on the Y mean? More specifically, where does Centroid want the table to be in the homed position? I'm assuming X0 is table all the way to the right. Still unclear where the saddle is.. at the operator or at the column?

Have a look at this thread: viewtopic.php?f=64&t=3638
Centroid doesn't "want" the machine in any particular way. You have to decide the way you want it and then tell CNC12 how you have set it up.

Thank you for the link. It doesn't clear it up for me. I don't know where I'm supposed to home the table and where the relationship between X+ on the VCP is relative to the table movement. I'm sorry to be so dense, but I'm lost on this.

There's no y prime on the knee mill in the example..
