Schaublin 125-CNC retrofit.

LMAO!

I doubt this drive will be reliable. It wouldn't boot for about 3 days, but now seems normal.

CONGRATULATIONS on first chips!

Edit: I forgot to include the last video:


The Schaublin has the two hall sensors on the X axis, so it has the second config shown in the LinixCNC homing guide:

 

The +X limit switch will also be used as the home switch. I am a little confused by the HAL on this axis:
# ---setup home / limit switch signals---

#net x-home-sw       =>  joint.0.home-sw-in    [HMOT](CARD0).7i84.0.0.input-00 - (No separate home switch)
net x-neg-limit     =>  joint.0.neg-lim-sw-in [HMOT](CARD0).7i84.0.0.input-01
net x-pos-limit     =>  joint.0.pos-lim-sw-in [HMOT](CARD0).7i84.0.0.input-00

in combination with the INI:
[JOINT_0]
TYPE = LINEAR
HOME = 180
HOME_SEARCH_VEL = 2
HOME_LATCH_VEL = 2
HOME_FINAL_VEL = 2
HOME_USE_INDEX = YES
HOME_IGNORE_LIMITS = YES
HOME_OFFSET = 180
HOME_SEQUENCE = 0

Do I need the HOME_IS _SHARED to inform it that the switch it needs is the limit switch, or is that used for home switch pin shared between multiple axis? I guess my question is "how do I net the limit switch to also be used as the home switch?"

The odd thing about a lathe versus is a mill, In a lathe we want home to be as far from the chuck as possible typically so full travel to + Z and positive X. So in this case it is home to limit, and then IIRC you set home direction to positive.

So positive home can be a shared limit switch. it is the exact opposite of a mill typically.

in the Axis setup tab in pnconf, there is a direction for Home, and you can just set the travel direction towards the  + switch as the home switch, and then set the Z min " at chuck as the Z limit. I hope that's less confusing. 

THanks, I think i wasn't clear, as the direction of homing is not the issue, it is simply how to net to both joint pins. Thinking about it, I guess I just need to net the input pin to both joint pins:

net  x-pos-limit    [HMOT](CARD0).7i84.0.0.input-00        joint.0.pos-lim-sw-in        joint.0.home-sw-in

I will try that tonight. I sometimes get confused by the signals PNFconf creates.  I made the mistake of trying:
net x-home-sw    =>  joint.0.home-sw-in    [HMOT](CARD0).7i84.0.0.input-00
net x-pos-limit     =>  joint.0.pos-lim-sw-in [HMOT](CARD0).7i84.0.0.input-00
Which of course errors out with the pin already assigned error.

I already have Z working, as it has no limit switches, just the home. I am thinking of adding addition limit switches though.

I tend to write my hal files as one input or output per line. I also tend to keep all connections to a certain net grouped together whenever practical. So something like this: It's a bit lengthy but very clear IMO. It makes it very easy to see if a net has no, or several, inputs (i.e. an error) and it becomes very easy to add or remove a single connection.
