Set x offset from home

Currently when I home, if I lower Z all the way down, it hits the vacuum tube.
I need to shift my X axis 20mm away from endstop.
How do I set this permanently so every time I home, it will move away 20mm and set that as home position

Would it be:
M666 X20
M500

M666 is worth a try and might work. You could skip the M500 until you are sure it will work.

As an alternate solution, you can use custom g-code for the homing. Something like:

G28 X
G1 X20 F300
G92 X0
G28 Y Z

This code could be triggered from a custom buttons in Repetier-Host, or from the V1 custom menu, or run from a file on the SD card.

Personally, I’d look for a physical solution so that the X limit switch is triggered 20mm sooner.

Ok so m666 code don’t work.

Anyone capable of modifying the X-tensioner for me? So i could 3D print it.

Or better yet modify it to add a m3 locknut, that way it’s adjustable with any length m3 screw size?

I don’t have a Lowrider, so I can only make “blind” changes. In the attached ZIP are two versions of the tensioner…one is extended to 25mm, the second extended to 10mm and then threaded for M3x0.5.

Ohh thank you, I will let you know how it goes :slight_smile:

Don’t hesitate to ask for changes/additions. As mentioned, I only have a vague idea of how this part fits on the Lowrider.

Well this was my original, with the added screw which I glued in place.

Seems to have done the track temporarily until I print the one you done for me :slight_smile:

I’m printing the 25mm version,
My only concern with the threaded version, as the limit switch will keep hitting it, over time it might get threaded.
I’m wondering if your 25mm design if it works can be then altered with customiser on thingiverse so that way others can alter the 25mm to whichever length they require for there machines?

So the 25mm works well, but may need to extend it to 27mm. There is a bit of a rub on the vac tube.
Are you able to extend it out to 28mm for a bit of extra clearance?

No problem. Resized to 28mm. Zip attached.
