Hi Chris,
It's likely you tried attaching photos etc larger than the 1.6Mb limit on LinuxCNC. Any digital camera will create a photo much larger than that limit.I use a free download program called paint.net for editing simple stuff. Bring a photo into it then do a "save as". It will take you to a preview image where you can do a bit before saving. Up the top left is a slider which allows you to compress the photo. The preview shows how bad the final image will be. You can compress almost any happy snap to below 1Mb and still have acceptable quality for posting. The "okay" button is down at bottom right.
There is a black round side plate on my machine that allows access to the horizontal quill clamp.See attached. I some cases they have another quill handle there which would be handy for manual use. I unclamped mine but the quill is stuck with what looks like old oil varnishing.
I'll have a look, if I get time, to see where the hydraulic hose goes. I suspect it will have the same rotary joint as the Z quill. It will need disconnecting there. There will also be an anti rotation/ travel stop pin somewhere.Then the whole quill will need to come out.
I'm confident you don't need to bleed the hydraulic hoses. The trapped air will act as an accumulator. So the air will compress up to the hydraulic pressure of 180 Bar. In fact I suspect if it is bled the switch/pump feedback will have conniptions. It would only have the flexibility of the hoses and oil to slow the switching cycle down.
If the claws on the tool clamp aren't retracted by the hydraulics the tool holder wont go all the way into position. The claws sit naturally in the clamped position forced by the springs. So if it looks like the tool holder needs to go further by a bit less than a centimeter then the springs are working, at least to some extent. If you have adjusted the setting distance without the hydraulics pulling the claws back then you have messed up the correct position for the claws.
Cheers,
David
