thanks your answer,
Actually, the y2 motor is currently going to the y1 motor position, but it is going very fast, can this speed be adjusted?

Homing for tandem axes is setup using negative numbers for the 'HOME_SEQUENCE' in the [JOINT_n] section of the ini file:
linuxcnc.org/docs/stable/html/config/ini...l#sec:homing-section

Alignment is then achieved using the 'HOME_OFFSET' value in the [JOINT_n] section.

It has been a long time since I used absolute encoder homing but I would suggest to add a 'HOME_SEQUENCE' to all of your joints as described in the link above and then compensate for the position difference using the 'HOME_OFFSET' value for one or both of the tandem joints.

A final update to this thread, using the anslog inputs on the Mesa 7i84 worked like a charm and I now have spindle load reading in Probe Basic.

While doing the setup I noticed that the four analog inputs on the 7i84 in mode 1 can still be used as normal digital inputs which makes the change from mode 0 to mode 1 very simple.

It's hard to not fall in love with these Mesa cards. So far they have managed to handle everything I've thrown at them.

 

Please post your ini file.

Currently, the y2 motor is going to the y1 position very fast. I should reduce this speed, how can I do this?
2.y jog button only moves y1 motor, how can I make it move both motors?

I observed wrongly, currently the y2 motor is moving itself to the y1 position, but it is fast, I will check how to reduce its speed.

hello,
I use gantry axis with gmoccapy.
The motors are absolute motors, there is no home sensor in the machine.
There are 2 servo motors on the y axis, this axis is approximately 7 meters long.
For example, at first startup, y1 motor position = 3.000mm
y2 engine position = 5,000 mm.
How can I send the y2 engine to the 3,000 position? What I want to do is to send the y2 engine to the y1 position and then make it work as a gantry when the y1 and y2 positions are equal.
Currently when you first run it for example position y1 is 2,000 and position y2 is 5,000.
When I send the y axis to position 100, y1 position is 100,000 and y2 position is 103,000. How can I make this work without any location difference between them?

The Z setting comes into its own if you have repeatable tool holders (I have TTS). You can premeasure your tools and 3D probe. I do this off line using  a toolsetter and a tiny granite plate from Tormach. It has a hole in it for the TTS holders so they sit flat on the plate.
Using QTdragon, you probe for the surface with tool 99 which holds the probe.
Then you can do a tool change to your desired tool and Z0 will be the surface of your workpiece.
This lets you generate a single gcode file for all tools, whereas my mate runs out gcode for every tool seperately and touches off as you would on a manual mill each time,

The tool table entries are used for automatic tool offset compensation (ie G41/G42 for radius and G43 for tool length) after a 'Tx M6' command.
If you don't use tool compensation but touch off each tool manually then the tool table is pretty much irrelevant.

I’d jump that way.

Yes it is usable.
When it let's me use ohmic probing it is working great.
It's a lot faster than the float switch, doesn't put pressure on any adjustments, and it doesn't push the material down. It seems like a much more accurate measure for pierce height.

I just realized. I have to select the starting points manually then it adds the lead ins etc.

I am currently using a 7i96s board to run my mill. When all is done, it will be a 4 axis machine with ATC. However, I have already run out of I/O (mainly outputs), so I'm looking to get a daughter card for expanding that. I would prefer it to be a serial card instead of a P1 connection as I am using the P1 connector for an MPG pendant.

I am planning on having the outputs mainly running relays for sub-spindle control and pneumatic cylinders. The sub-spindle would just be using the same 0-10V signal that the main spindle uses, but with a different set of relays. Maybe connecting a few limit switches on the inputs as well.

I was looking at boards and saw the 7i84 and was wondering if this would be a reasonable selection for this use case. I'm not very familiar with the daughter cards that mesa offers and there are so many of them. Perhaps the 7i73 would be the better option here since I want to add the MPG? That would allow the P1 connector to stay open, but I'm not sure I'd ever need the P1 for anything else and I already have the P1 MPG firmware loaded.

Any input here would be great. I've never run a daughter card before.

Some of the Stepperonline products are re-branded Leadshine items.  Some are identical, some have firmware changes.

It's possible that the Leadshine software will work with your Stepperonline drives, but don't be surprised if it doesn't.

My SO T6 servos are rebranded LS, and while the LS software will communicate with the T6 drives, there are some software features (i.e smarter auto-tune) that are disabled in both versions of the software.
